So, I've been spending the better part of an hour scouring over the Anandtech teardown gallery of the prime trying to get a decent understanding of the GPS/WiFi antennas and the underlying design flaws which contribute to these features messing up; namely the giant metal shield of a cover and the placement of the antennas. They're not exactly in a bad place, but I guess Asus assumed that if you were using WiFi/GPS with your tablet then you would always do so with the screen facing the AP/satellites. In reality, mine at least, it's the back of the device generally pointing to these things. Maybe I place my network hubs in strange places and enjoy astronomy apps too much?
Now on to the actual question, especially to any of you who have gotten the device and been brave enough to peek inside it yourself; would creating my own plastic windows/metal grates within the aluminum backing actually help anything? Do these antennas broadcast a 360 degree signal or are they directional? The motherboard itself would allow decent signal to get to the transmitter wouldn't it, so long as the case does?
My order isn't set to ship for another month, but I think I'll be getting this tablet regardless of the known issues, though the audio/video problems with the miniHDMI port make me a bit nervous. This thing will still be a power-house even as better spec'd tablets come out, just like my single-core Desire Z is still pretty relevant and decent. Just not top-of-the-line, and it wasn't for any real amount of time, but that's just how these things go.
Ideally, the antenna would couple to the whole backplate, making a big slot antenna (but then it starts to risk being too directional). It's just as probably that the issue is noise or feeble pogo-pin connectors.
If you do make a cut-out, it needs to be about 1 wavelength larger than the outline of the antenna (and you risk de-tuning the antenna if it was designed to operate in close proximity to a groundplane)

Coupling to the backplate, though increasing power decreases accuracy doesn't it?
I hadn't thought of the pogo-pins as a possible culprit, that's certainly possible.
Couldn't I make a couple windows and retro-fit either some plastic or plexi-glass into the design? Would that help keep from de-tuning, especially if kept to a small size with accurate positioning?
Thank you for the response, I know nothing of the finer details on GPS and other wireless signals.
*Edit: After re-reading and thinking, I actually understand what you're saying. Plastic or no, any cutout would need to be a very specific size larger than the antenna itself which would take more than I would be able to do I'm sure. Oh well, I know I'll still love this thing, so long as the miniHDMI works properly, I'll be happy. Phone's GPS works like a dream.
And now I apologize. I found it odd not finding topics on this, but now I've found them and have a bit more of an understanding on the matter. Namely that the cpu seems to have a strong possibility of creating interference for the chip. The casing apparently just worsens the issue.

How sure are we about this? I've read that Apple puts their WiFi antenna behind the black plastic logo on their WiFi-only models for exactly this reason. Not only that, but on the 3g models they simply have all the wireless modules placed on top of the device where they are covered with black plastic as well.
It seems to me that a stupid plastic apple cutout - a complex geometric shape - is not likely capable of being as "tuned" as a rectangular cutout. Yet, I think it's safe to say that the 3G and WiFi versions of the iPad have similar if not identical WiFi performance. That is to say, I don't think manufactures are using the aluminum back for anything other than looking pretty. I think it's safe to hack away at.
Thoughts?

Maybe for some heat dispersion too?
I wish they would start selling the back plate only (like they do with ipods etc)
That way i'm sure someone could cutout a shape and try the antenna behind a plastic window etc, but youd always have the option to put the original back.
I wouldnt mind modding mine after the garantee has ran out.
I think Asus might consider making an after-market backplate that they would fit to your Prime after they have fully tested the issues.

I've been thinking that even if Asus didn't some third party will. And I'm willing to get to cutting the day it arrives if I can determine it'll help. However, I don't want just an open grate for dust and junk to get into. Maybe just a thin fabric filter, or should I close it up with some plastic/plexiglass and epoxy?

I don't see why plastic wouldn't work. It's what the iPad has and it seems to work out in that case.
You should consider cross-posting this in the "General" forum. It is a "question", but the General forum gets a LOT more eyeballs.

i agree, this post should be on general... this would be a great solution, a homemade plastic ipad-like hole... we need it, and if third party doesnt do this, we will have to do it...
well, but anyone tested the device without the case to see the real power of the wifi-gps-bt ?

I will be, but it's still a good two-four weeks before I have mine. All mentions of it I've seen in general never get answered, I haven't seen anyone comment on whether or not they've tried without the backing. Probably because most aren't willing to try and heat up the glue to do so or damage the thing in the process...
Some expertise required
Does the aluminium back plate attenuate both wifi and gps signals? From what I have read it seems to be confirmed that this is the situation, although other factors such as internal interference have NOT been discounted, nor has the connection method (gold pogo pin) between motherboard and the antennae (blackened out pcb strip). I have noted on the TF101 Transformer teardown, a very similar placement of both WIFI and GPS antennae to that on the TF201 Transformer Prime - near the top edge and adjacent each other. Looking at similarities between models, an obvious and perhaps too simple explination would be the aluminium back plate. There does seem to be some interest in experimenting with making some holes (similar to the speaker grill), on the back plate in front of the antennae in the hope that it MAY improve reception. I have read numerous posts and was hoping that someone may have tried this. I don't want to hear about the merits of having or not having a GPS and how it matters to them personaly etc - lets focus people, but whether someone has had the ability and knowledge to try it. I am unsure given the wavelength of both GPS and WIFI (1.2 / 1.5 Ghz) whether mutliple small holes would do it. I feel that a transparent plastic window may be required. I do not believe the back plate is used a coupled ground plate etc. and it is used purely as the chasis. Come on - there has to be some smart engineering graduates/professionals who are willing to give this a go...it would have been nice if they were paid by ASUS but that seems unlikely. Point to note - that the GPS and WIFI antennas (there are two for the WIFI on the TF201) would be obtaining some reception through the front gorilla glass and plastic (on which the antennae are mounted). My question is - what and IF modifications are necessary to the back plate to obtain better reception. Any ideas?
I have not seen a single test where anyone proved it was the back plate. Anyone have a link to a test that shows the prime navigating successfully without the back plate?
I have had my Prime for a week now and it was working perfectly. I got the ICS update and everything was working even better. I never had any wifi connection issues. Today the prime will suddenly no longer connect to wifi. It appears to not be picking up the wifi signals anymore. When it does manage to pick up a signal it shows up as a small dot and still can't connect. It wouldn't connect at work this morning and when I came home it connected for about a minute and then dropped connection and would not connect again. I rebooted several times, tried a hard reset and then finally resorted to a factory reset. It still did no good. My unit was previously picking up my wifi signals with full strength usually and sometimes 3 bars. Not sure what happened but I guess I'll just take it back to Office Depot for a refund while I still have time. Not sure what I'll do now because i REALLY liked the prime during the time that it was working right.
If you're under warranty Asus will tell you to return it for a fix and hopefully their turnaround time is measured in days, not weeks or months. Sorry for you, it seems the Prime is not as durable as I thought, poor quality control is probably the culprit.
I would go the repair route but I'm kind of afraid that I'll then get stuck with it if they can't fix it and I've missed my return window at office depot. The bad thing is that there is no other tablet that I'd be satisfied with now that I've experienced how smoothly the quad core tegra 3 Prime runs. I had a Xoom before the Prime and I gave it to my fiancee after the Prime arrived. I really liked my Xoom too but the Prime is a MUCH BETTER device (when it worked).

Haven't heard of this issue yet, that is a new one. If you are in warranty, take it back and get a full refund or a replacement. If not, contact Asus.
However, good luck with contacting Asus and getting a timely response. I am on day 3 of just waiting for a return email. I did it through their own messaging service on their site, not regular email. I would appreciate someone responding to my simple questions, but they must not have the time right now.

I know that is why I was so shocked when it happened this morning at work. I was hoping that it was just something going on with the wifi connection at my office. I now that there are Primes with bad wifi out there but mine doesn't just have a bad connection now, it can't connect at all. I figured that I had been lucky enough to get one of the good units considering how incredibly well it had worked over the past week. At least I've only had it for seven days so I can still return it to Office Depot. I just hate the thought of being tabletless now. Guess I gave my Xoom to my fiancee a little too fast.
Well my prime got to the point where it would connect when I was next to the router but would either drop out or lose signal strength when I moved away. I have scheduled for a return to office depot. Yesterday I found another prime in stock at hh gregg so I picked it up. This one once again has excellent wifi service just like my first one did for awhile. I am hoping that this one keeps it. I still can't understand what happened to my first one. The only thing that I had done before the wifi crapped out was install a memory card and I don't see how that could have had anything to do with it. This experience has shown me though that the prime is definitely capable of giving good wifi service and that there is something going on other than the aluminum backplate. Having seen both sides of it I can see why no one would be satisfied with the wifi performance it had when it went bad on my first one. Maybe it is a mechanical issue with the wifi antenna connections coming loose in the system? I don't know how likely that is but it is the only thing I can think of based on my experiences with the issue
It very well could be the antenna wires are coming undone from the Wi-Fi adapter it would allow you to connect right next to a router but not much further away.
Sorry to ask the obvious, but did you power down your Prime before starting again to see if the problem was still there. I'm sure this was the first thing you did, but just checking.
The wifi on my Prime cut off last night but it came back after a quick reset (holding down the power button for 13 seconds or so).
Yes I powered down, tried a hard reset and finally tried a factory reset and none of that helped with the problem. It was a complete night and day difference in performance that was quite shocking. As I said if people are experiencing that kind of performance from the beginning then I can totally understand the complaints. So far the new unit is having the same great performance as my other one had at first.
From looking at the Prime teardown, your wifi loss may be due to a loose connection. Instead of running a pigtail directly from the chip lead-out to the antenna, the Prime uses spring-loaded pogo pins (1st pic) as intermediate connectors.
Second pic shows the pogo pins for the main wifi and GPS antennae. The spring-loaded pins are pressed against the copper pads of the respective antenna (3rd pic). Suffice it to say, this isn't the most secure way to connect the antennae.
Aside from possible broken or intermittent connection, it also looks like a high-loss connection, and could contribute to attenuated signal reception. My guess is that this may be the main culprit of wifi/GPS woes, with the metal shell being a contributing factor.
The 4th pic below is a U.FL connector that's normally used for antenna pigtails. The lip has an outer overhang for a secure connection.
My guess is that the tablet was bumped and something shifted a bit, breaking the antenna connection.
This is FYI only, as the unit isn't user-serviceable. It does look like a simple fix, but you'd have to open the unit. Edit: You can try smacking the top edge of the tablet a few times and see if it will jar back into place. Worth a try.

Heck yea it's worth a try!
And to the OP - since it only just happened today, I think I would wait a day or two to see what else might develop. I know you've tested it out in two different places, but it came on so suddenly, maybe (hopefully ) it will go away?
Unless of course waiting a day or seeing what might be different tomorrow would interfere with an exchange or return policy. If you are still within a window and are out of time soon, then you gotta do what you gotta do.

very interesting info as some users have flexed device in that area n now supposedly have good wifi n GPS now. this will affect the signal strength more tthan the backplate.

Before packaging my Prime up to be sent to ASUS for RMA. I did exactly that, I did the black part of the screen at the top with my kunckles kind of hard a few times.
My signal went from 35-40% where I was sitting at to around almost 70%.

You really can't use terms like "good" and "more" beacause they're all relative. "Good" compared to what Wi-Fi/GPS is with other devices or against other Prime's? And until it's known for sure that all devices are suffering some type of signal issue saying the unproven pogo pin expose is "more" or less an issue than anything else is premature. It's impossible to compare Wi-Fi performance on a forum because each testing condition is different and there's no baseline to have a common discussion around. To see if there's differences between Prime's a couple of them need to be tested side-by-side at the same time.
hang in there demadarin - I think Barry is weakening and we will eventually convince him there are potential issues beyond the back plate.

I'm like Spock on Star Trek - it's all about logic. It seems more and more people are having their signal change when squeezing above where the antennas are. That certainly points to a common issue. But even the hand-picked Prime Asus sent to Anand to replace his defective sample still peformed poorly against the TF1. So the metal back cover's not an innocent victim (yet).

With one minor difference, Anandtech never flexed his Prime. You couldn't blame the pogos so the backplate took the hit.

Look at it this way, when Apple move the antenna from behind a plastic disk on the iPad1 to behind a metal speaker grill on the iPad2, performance took a hit. The Prime has no opening at all for a signal to travel through and Asus makes less in a year than Apple spends on R&D. Ergo, the metal back cover is and will remain a factor.

Agreed, but by how much in comparison to a tarnished pogo contact? And as time goes by, the influence of the latter will be increasingly pronounced. BTW, the TF101 does not use the pogos, the antennas are hardwired. I also noticed that the mainframe is made of solid aluminum and yet the 101 has never had any rf problems like the Prime.
With users experiencing sudden change in signal level after making good contact with the antenna, I'd say the evidence of inconsistency in performance is pretty convincing as to the real cause of the fault.

EVEN Spock went postal when he realized humans are a complex being n that not all things obvious are always the truth. That some things cant be explained by facts alone. As there could always be contributing factors. Spock was like Data, from the next generation. Even Data was Assimilated..lmfao. my father loved that show.
Off topic..but did you know the guy who played luetenant worf wanted to originally be the Captain? They denied him the part over Picard or whatever his real name was. I still laughed knowing the guy who played Jordi was the guy from reading rainbow.

Correction needed here. Anandtech last tablet test held prime wifi on par with tf-101. Then he also said range "Might" be an issue. He never said Prime wifi performed badly after his last test.

READ THIS POST AND POST 74 AND FURTHER
Have you ever seen such quality in the GPS signals and the fixes? (picture 1)
Ever since I got my TFP in early January I have been trying to find a way to enhance the GPS and the Wifi. I read just about all the threads on these subjects and tried every tweak. Even the crazy ones ;-) But because of the form factor I wasn't going to drill holes and put antennas on the back (respect guys, awesome work)
It started with a poster that got flamed straight away. He put a phone on the top right hand corner and got a better GPS. I felt sorry for him because everyone treated him like a retard. Just for the sake of being able to put the flamers in their spot I gave his idea a chance.
And it worked!!! But it was not practical. I can't walk around with a phone pressed against my TFP. But it was a start. Something started happening.
Next came the screwdriver trick. Even better result. Then I discovered the paperclip trick. Again improvement. But still not good enough and certainly not stable. It was difficult to reproduce. It became clear to me that positioning was very critical.
On the Wifi side people started enhancing their signal by placing foil the right Wifi antenna. Then they started using beer cans. It worked for some. But for others it didn't work. Theory was that somehow the Wifi signal got shielded forcing the other Wifi antenna to kick in. Tried it. Worked sometimes and at other moments didn't work. But there was something. And again it became clear to me that positioning was very critical.
Furthermore I started fooling around with grounding to the back plate. It had a dramatic effect on Wifi and GPS. As soon as something touches the back plate the signals die. I got the impression that the Wifi and GPS antenna were to close to each other and with all the RF signals they were screwing each other.
But all together there were things happening. I started documenting exact positions and sizes of the tweaks I was applying. Wifi was reasonable for me as long as I had a good base signal. GPS had my attention. I could get an external GPS, I could tether from my phone, I could buy a map, I could ask directions.
But NO!!!!
I wanted the GPS inside the Prime to get a reasonable fix.
It has cost me a lot of hours of trying, tweaking, adapting, and documenting.
But......
I FOUND THE 10 CENTS SOLUTION!!!
You only need to buy a 1 mm stainless steel cable.
Instructions (also see diagram):
1. First get yourself a beer. And drink it (this is the best part)
2. Then cut yourself a square 15x25 mm from the can (carefull)
3. Stick it in the right place onto the glass
4. Make sure it is isolated with electical tape on the topside
5. Place steel cable across the isolated square (I don’t know if this matters but I used 9,75 mm length = 0,5 x wavelength of GPS)
6. Fix it in place with electrical tape
And ......
ENJOY A GOOD GPS (better than my HTC Sensation)
Up to now this is the best result I can get.
Probably sizes and locations can be optimized.
However my experience is that the cable has to extend outside the plane of the TFP. Either vertical or horizontal. As long as it is inside the confines and flat on the glass of the TFP the signal dies instantly
And the electrical tape on top can be exchanged for something better looking.
Customize it like a sticker of a mouse with the tail being the steel cable.
Or a droid sticker with antenna ears upwards.
Outside and in the car I get a 4 second lock and after 10 seconds 15 sats and 10 locked. Inside has improved but not really good enough.
I have reset the prime before testing, cleared AGPS and Wifi off.
I hope you guys enjoy and appreciate my solution.
And if someone finds a better or more elegant solution please post.
Have fun
Oh I forgot to mention. The trick also works with the paperclip. Use a small paperclip. When straightened the length is 95 mm. Also works. I turned to the steel cable because I wanted something flexible.
very cool.
I currently have a beer can piece myself on my prime
-not as precise as yours, but it improves my wifi
not a beer, but after this j i shall try!
You guys are awesome....I've been looking for this all day..... a reason to drink beer tonight ^_^ oh and a possible gps solution without opening my TFP

Perfect turn by turn navigation.
On the highway about 10 locks and in urban area a minimum of 6 locks.
And all the time average 14 sats in sight.
I have not tried it yet in an area with very tall buildings.
I think the highest buildings during my tests were 6 floors.
If this can be independently verified (and sounds like it can be), then someone could definitely make a little money with this. Not enough to retire on, but a little spending money.
A question: could this be made into something that could clip onto the Prime and so be easily added/removed? While I wouldn't tape anything to my Prime, I'd clip something on it if I were to want GPS to work (which I don't actually, but being speculative here).

Yes can be done.
I have been trying some solutions myself.
But the positioning turned out to be a critical factor.
Had to work that out first.
Wanted to share those results first.
But some sort of minimized and customisable clip on device would be nice.
Either pimped or just simple
I'm thinking you could use a simple clip like we use at home for potato chip bags. Line the inside of one part of the clip with the require metal, add in the wire, and then you could simply clip it on when you need GPS. Those clips aren't particularly strong, either, so no worries about damaging the Prime.
I might give this a shot myself this week, if I get some time.
The 12 Steps to ruin.... and a Hangover
My attempt (not really but could be fun)
1. Drink one can, cut open and place on screen.
Tape was too old. Can kept falling off.
2. Get another can and drink then place on screen again.
New tape stayed on but can didn't work.
3. Get yet another beer. Had a brainstorm idea to try doing the same for Wifi... got another beer.
Drank beers, needed a pee. Wife threw out the empties.
4. Got another two beers. Rang friend to ask if he had a beeter metal cutter....
5. Got two more beers then forgot what I was doing.
6. Glot two more bbers. Needed another pee.... Came back stood on berr cans. They were hiding on the floor.
7. Grot a new crate of beers in from the sheller hic! Drunk clan cut finger with can opener. Oh Eck...
8. Opened nudder bleer. Got drill out and dilled lotsh of oles on can.
Bol*x.... need a pee.
9. Sloped can wid whisky bottle... Poored whiskey on wire... Sh1t.. where da fcuk did wire come ffrommm???
10. Passt hammmmer to schreen. Bloke grass an spong at glue.
11. Glue noo worrrk. Need beeerr. hic!
12. Shud not put fingerss in live lectric shockket!
Fin............. Dont work.
zzzzZZzzZzzzzZzzzzzz
So I guess the prime as a glorified beer coaster wasnt too far off since it can improve signal strength.
hey guys come on.
I'm trying to start a serious thread and now you are turning it into something hilarious.
Well they always say 'keep on smiling'.
Had a great laugh.
Great story.
Let's see if thereś any beer left.
Cheers guys
Jesus.. you couldn't pay me to do this.
BTW, I got better than you without this nasty hack. I have screenshots of 18ft right in my backyard. No tin foil, no duct tape, not guitar/bike wire.
But none of it matters... AS YOU CANT DRIVE AND GET IT TO WORK

Perfect turn by turn navigation.
On the highway about 10 locks and in urban area a minimum of 6 locks.
And all the time average 14 sats in sight.
I have not tried it yet in an area with very tall buildings.
I think the highest buildings during my tests were 6 floors.

I actually just got 18 ft in my brother's front yard Same place I kept getting nada for a couple weeks. No mods, but not stable either. Soon I'll have external antenna and be done with it
*EDIT: Obviously with data on, but I was getting 1 bird in and out of view with the same setup pre-.15. That is not to say .15 in any way helped this.

So what antenna will you be using?

Have you ever seen such quality in the GPS signals and the fixes? (picture 1)
Ever since I got my TFP in early January I have been trying to find a way to enhance the GPS and the Wifi. I read just about all the threads on these subjects and tried every tweak. Even the crazy ones ;-) But because of the form factor I wasn't going to drill holes and put antennas on the back (respect guys, awesome work)
It started with a poster that got flamed straight away. He put a phone on the top right hand corner and got a better GPS. I felt sorry for him because everyone treated him like a retard. Just for the sake of being able to put the flamers in their spot I gave his idea a chance.
And it worked!!! But it was not practical. I can't walk around with a phone pressed against my TFP. But it was a start. Something started happening.
Next came the screwdriver trick. Even better result. Then I discovered the paperclip trick. Again improvement. But still not good enough and certainly not stable. It was difficult to reproduce. It became clear to me that positioning was very critical.
On the Wifi side people started enhancing their signal by placing foil the right Wifi antenna. Then they started using beer cans. It worked for some. But for others it didn't work. Theory was that somehow the Wifi signal got shielded forcing the other Wifi antenna to kick in. Tried it. Worked sometimes and at other moments didn't work. But there was something. And again it became clear to me that positioning was very critical.
Furthermore I started fooling around with grounding to the back plate. It had a dramatic effect on Wifi and GPS. As soon as something touches the back plate the signals die. I got the impression that the Wifi and GPS antenna were to close to each other and with all the RF signals they were screwing each other.
But all together there were things happening. I started documenting exact positions and sizes of the tweaks I was applying. Wifi was reasonable for me as long as I had a good base signal. GPS had my attention. I could get an external GPS, I could tether from my phone, I could buy a map, I could ask directions.
But NO!!!!
I wanted the GPS inside the Prime to get a reasonable fix.
It has cost me a lot of hours of trying, tweaking, adapting, and documenting.
But......
I FOUND THE 10 CENTS SOLUTION!!!
You only need to buy a 1 mm stainless steel cable.
Instructions (also see diagram):
1. First get yourself a beer. And drink it (this is the best part)
2. Then cut yourself a square 15x25 mm from the can (carefull)
3. Stick it in the right place onto the glass
4. Make sure it is isolated with electical tape on the topside
5. Place steel cable across the isolated square (I don’t know if this matters but I used 9,75 mm length = 0,5 x wavelength of GPS)
6. Fix it in place with electrical tape
And ......
ENJOY A GOOD GPS (better than my HTC Sensation)
Up to now this is the best result I can get.
Probably sizes and locations can be optimized.
However my experience is that the cable has to extend outside the plane of the TFP. Either vertical or horizontal. As long as it is inside the confines and flat on the glass of the TFP the signal dies instantly
And the electrical tape on top can be exchanged for something better looking.
Customize it like a sticker of a mouse with the tail being the steel cable.
Or a droid sticker with antenna ears upwards.
Outside and in the car I get a 4 second lock and after 10 seconds 15 sats and 10 locked. Inside has improved but not really good enough.
I have reset the prime before testing, cleared AGPS and Wifi off.
I hope you guys enjoy and appreciate my solution.
And if someone finds a better or more elegant solution please post.
Have fun
Oh I forgot to mention. The trick also works with the paperclip. Use a small paperclip. When straightened the length is 95 mm. Also works. I turned to the steel cable because I wanted something flexible.

I think that's the point.
Kill the primary WiFi (if that's what it does... and I think it does) with the aluminum, then use the wire as a conductor for the GPS signal, just kind of funneling it to the right area for the internal antenna to get a concentrated blast. Per RF theory I've seen around here, the signal then doesn't need a hard line to the antenna, it'll travel that little gap from covered wire to antenna easily.
hey! That crazy asian with the phone on the corner was me! I've been meaning to post my further investigation on this and this is what I did.
1. Bought a Moco case on Amazon for like $12.
2. Put Prime in case.
3. Cut a 5 inch speaker wire. The tiny ones, not monster cable but them average size wire about 22 gauge (?).
4. Place the wire under the case but above the Prime in same location as yours. It stuck out so I bent the end and tucked it into the headphone opening.
5. Went for a drive. I drive a bronco and with the case set up to stand the Prime up, I was able to watch GPS test as I drove. Kept very steady GPS lock with no less than 4 at a time. Tried Google maps with Bluetooth data tethering to my phone to draw map and now I have a 10.1 in screen gps !
I think getting a case (any case) is a good investment for your Prime. It can also very casually and discreetly hide any of these " additions" to your Prime to enhance certain features like those with the foil wifi "mod".
So I didn't get to drink any beer but I sure will not drink scotch out a can!
OMG beard, too funny ...lmao....
Hi,
this morning someone sent me a link from Tom's Hardware about this tablet. The articles mentions that some people have modded their case to improve GPS signals.
I wonder why Asus don't revise this product to address this issue.
Sent from my HTC Desire using xda premium
You DONT even have to do all that anymore. Asus is offering free GPS dongles to people who purchase a prime. Offer ends in July. Just take a look in my GPS dongle test thread. Then take a look at the link in my signature THST says positive transformer thread.
Prime is a great device. Get one asap
Well first of all, I find it hard to believe that the aluminum case is causing 100% of the problem. Because, if it were then like you said, why not just change the design of the backplate? My guess is that simply adding a plastic strip to the top of the backplate would not improve GPS performance that much. And personally I think the plastic strip look is ugly as hell. What they could have done is kept the all aluminum finish and just relocated the antenna to behind a speaker grill, which is similar to what other devices with metal casings have done. I am sure the GPS still wouldn't be 'professional grade' but it would at least be better than what we currently have.
Either way, the whole GPS problem was something that was obviously not 'caught' until really late in the production process. If it were caught earlier, I am sure something more pro-active would have been done about it. But by the time they found out, they were in too deep to make a hardware change as they were most likely already in mass production. The early regions of where the device was released they had already advertised the thing as having GPS, both on the box and on the official spec sheets. Then when it was released these people found out that GPS was virtually non-functional and ASUS had to quickly back track and pull GPS as a feature from the spec list. My guess is their lawyers told them they need to do something to avoid a class action law suit and any further bad press around this whole situation. So their options were:
1) Recall the device and then modify the hardware in some way to fix the GPS problem (whether that be done via a newly designed back pate or whatever). And then any new ones produced would obviously have this hardware change incorporated as well.
2) Offer a free addon that improves GPS performance.
As we now know, they went with option 2, which I am sure was also the cheaper route. Also, option 1 would imply an admission of guilt in that they messed up. The GPS dongle option allows them to say: "Although the TF201 is not a professional GPS device, as part of our unwavering commitment to our customers we are offering all customers who purchased a TF201 system a free external GPS extension kit, called a dongle, which may help improve signal reception and optimize the user experience".
Honestly I do not care about GPS in a tablet and I will probably only ever use my dongle a select few times in the entire span that I own and use the Prime. I do think it is good that ASUS is doing something about it though. Other companies may very well have just brushed this thing under the rug and moved on with life (which is what I assumed ASUS has been doing until we found out about the GPS dongle).

+1...although the solution of a GPS dongle really kills the idea of a TRANSFORMER prime...cant use it with the keyboard dock, and its not as flush and they said it is..you wont be able to use majority of the leather cases and etc when you are using the dongle
I have owned the prime for months. My wifi strength is fine and I dont use GPS enough to justify the problem.

They are, for the 300 and 700 series, back to plastic where the radios are going. iPad tried behind the speaker grille and it still has issues. Its better than nothing but def not perfect.
Yes, the black strip doesnt always look as appealing, however you could cover it with a case or carbon fiber sticker or whatever, i'd much rather go for plastic strip over no radio reception.
And also yes, the interference can definately be 10000% caused by the metalic back plate. Both by blocking the signal and RF noise. Everything pretty much is grounded to the metal back and it, in turn, has a lot of RF noise associated with it. If i attach a lead to the gps or wifi contact inside the tablet and have the wire run outside the tab i get excellent reception. Once that wire goes within about an inch of the tablet the signal drops dramatically. Even if the access point is on the proper side of the tablet so its not blocking the signal.
Asus knows how to make killer electronics. they did an amazing job on the prime, however the demand caught them off guard. They tried to do something different with the metalic design and got caught with their pants down. They will get it right eventually and in the mean time we are at least getting SOMETHING (free dongle for gps, why not?)
The prime is a great tablet, awesome for watching movies, playing games, browsing the internet. ya, the wifi is not that great, i look forward to mods for using the dongle for wifi instead of GPS, but in the mean time this is the best we got, and its good enough. When the 700 comes out i may sell my prime for that but i got money in my pocket. if your on a budget, buy the TF101, its still better than any other tablet (aside from the 201 IMO), or wait for the 300 series which will still be a cost efficent tablet.
Asus is doing their best to remedy this situation. They are a big company and big machines move slow. Considering their track record i will still continue buying their products. I have been impressed overall by the prime, and the 101 before it, and look forward to the 700 when it comes out. Continue doing your research and determine what is going to be important for you (and if you do go Prime make damn sure to test it every way you can before accepting it).

This last weekend I was fustrated while vacationing when my Prime could not hold onto the hotel WiFi connection because of the distance to the router, yet my HD2 phone had no problems. This was the first time poor Wifi affected me. That got me thinking....
Looking at the fix made to the T700 to improve Wifi signal (and GPS), why couldn't a similar DIY mod be done to an existing Prime's back? I dont think cutting a slice off the top of the aluminum back is a doable option, but what about just cutting or drilling a large hole over the antennas, and filling in the hole with plastic or epoxy. This could look similar to the black oval plastic "wifi window" on the 3rd generation iPod Touch.
I'm thinking of trying this but wanted some input from others before trying. I looked at the other hardware mod thread here, but that concentrated on adding external antennas. According to that thread, once you removed the back, Wifi improved dramatically.
I think this was discussed before..but if you are feeling brave enough, let us know how it turns out man
This idea has been talked about in great length, but general consensus was that it would be too difficult to add a plastic window to the back of the Prime, because all of the hardware physically attaches to the aluminum back plate of the Prime.
You you be voiding your warranty by taking the device apart. And there is a very good chance you would render the device 100% non-working while doing the mod.
If the WiFi really doesn't meet your needs, return the tablet.
I'm glad I sent mine in to get it fixed, I am getting mine back tomorrow and that will make 10 days. I figured they would be pretty quick at fixing the wifi by now

Sorry, but this is not an option for a second hand Prime with an unlocked bootloader.
I'll have to take another look at the tear down pictures and video to get a feel of the space between the electronics connected to the back and the back itself. I have no fear of eventually opening up my Prime as I have opened up many phones in the past.
I had the same problem while on vacation in Mexico, my HTC Eco 3d picked up the hotels wifi no problem but my Asus didn't. I'm so happy I picked up a Asus WL-330N3G portable wifi router based on someone suggestion here, I wouldn't been able to work without.
Basically placed the portable router where I had the strongest signal in the room, and was able to use my prime anywhere in the room. An on top of it the router is very small, and can be powered by a USB port as well. As a bonus I use it as a gaming adapter for my ps3 when I'm home.
I think getting a portable router is a lot easier option then modding the back of the Prime.

Seriously .
ive said this before but could another idea be wait for the 700 to come out and then wait for some inner photos to be taken. If they look similar to the prime then could we not just try and buy a 700 backplate and try and fix it to the prime?

What about drilling small holes in the area where the wifi antenna is, creating a sort of a mesh? Could be very easily done with a drill with a small enough head by very carefully and slowly drilling into the aluminum.
I don't know if that would improve the wifi signal, but it is doable.
Might want to consider one thing though- People have been getting different wifi and GPS readings on unmodded primes, meaning that the problem is not necessarily the aluminum cover, but rather the quality of construction, components, etc.

I'm sorry, Faradays law says this will not work, for RF, mesh or solid is the same.
The contact area of the pingions on the motherboard to the antenna are realy tiny,I think replacing the pingions on the mainboard for small coax will improve, The wifi chip is at the other end of the tablet, the signals have to cross the entire device. I even saw they route the wifi signal trough a series of PCB trace and cables to the place where they connect to the antenna. I think replacing these connections by new a cable with at one end an MMCX and the other end solderd to the antenna, will improve the reception.

The other thread linked in the original post has all information regarding this topic.
Creating something like the 700 would be basically too complicated (though never impossible)
We won't know if the 700 back plate will match up until it is released (i doubt it is worth the work)
The external antenna works wonders, and can be made "removable"
A simple wire from the pogo pin that is isolated from the glass/aluminum will increase connectivity
Here is another link for good reading...

I've read through both of those threads, the one I posted and the second one posted above. Unfortunately they both went the route of replacing the existing antennas with wires or external connections. The closest one to my idea was this:

Totally possible IF you wanted to kick it up a few levels now that the hard work is done and shows an antenna wire can hep. Essentially steal Apples' idea but keep it simple and make it home grown.

Like I said, slicing off the top of the back and covering it with plexiglass is probably too much. I'm thinking more like just a hole, over the existing antennas, covering it with epoxy, and making a Wifi Window like that on an iPod Touch:

i just had a great idea. Based off what the linked thread was earlier,
It would be a handle on both sides, makes your TFP like a briefcase and eliminate the ugly/bulky antennas. Of course it won't be as powerful, but this would let us put antennas in the handle and increase reception. of course, it would require holes to be drilled in the back, but we can easily stick that on (and it would be very strong). It can be easily created with fiberglass, a color could easily be created and the brush strokes could be done as well. and a little gloss could be added after we have painted/added the brush strokes and get pretty close

Very nice design The handle is a great idea. All you need to do is run some wires through the handle. That is all my WIFI attached antenna are doing in my "Optimus Prime" mod. As long as you get the wires away and above the metal backplate your in business. You can check out my link in thread for the original mod. GL m8
Here is pic of two wires coming from WIFI pogo pins. Raised out and above
the metal backplate. All you would need to do is run wires through a nice handle and you will get amazing wifi or GPS.

I've read on this forum that some (or one) devices (not the TFP obviously) have their wifi antenna located behind the speaker grill in order to allow proper wifi reception.
