I can repeat these results over and over again on my Prime. A good distance from my router (through 2 indoor walls, 1 outside brick wall) I get the top 4 throughputs on Photo 1. I cannot stream video without an awful lot of buffering and everything else is slow. With some testing I found if I put that little piece of foil on the face of the tablet(Photo2) then I get the bottom four throughputs and I can stream video until the cows come home with no buffering. It seems simple and works well on my unit. And again, I can repeat the results. I've been using this for three days now and am really happy with the improvement. I'd be real interested in knowing it this affects anyone else's unit the same way. If it does let everyone know and this may be a quick and easy way to help with your WiFi without having to result in disassembling your Prime or doing an RMA.
I'm planning on painting it black and taping it the the face.
See post 99 for details of my installation.
That is quite impressive. I'm game to give this a try. How far down the back of the Prime does the aluminum foil go?
I remember the little antenna earlier model iPhone users stuck on their phones. Perhaps something like that can simply be stuck on the Prime's glass? But, in your situation, the foil going over the top and down the back may also have an influence. I'm going to see if this improves GPS, too! My wi-fi is decent, but my GPS in non-existent at this point.
Thanks for the post...

Holy Crap. I'm going to try this when I get home -- I've got a dead spot in my house where my WiFi drops off almost completely. If this works, I'm going to 1) laugh, and 2) think about all the physical damage that some people have done to their Primes in the hardware modding thread, and then 3) be sad for them, and then 4) laugh again, but bitterly.
Keeping the fingers crossed.
Next thing is foil hat!
On a serious note, quite interesting to see results.

Also, have you tried putting your prime in a portfolio-type case (like the Minisuit) with the foil on it? If so, does it still work? If so, that would be excellent, because the case would hide the foil.

Wow so cool! Even though we shouldn't have to do this lol. Brings me back to the days of my modded wifi dongle with tin foil upgrades to "borrow" my neighbors connection haha.
Damn I'm out of tin foil, I'm gonna run to the store and report back! Even though my new C2 serial get almost identical speeds in my living room in my apartment. Let's see how far I can go!
What about some copper conductive tape? A thin strip of it.
Interesting......simple yet effective, it seems
What happens to your GPS signals if you move the foil over to the left a wee bit (above the GPS antenna)?
I don't have a problem with Wifi, but I certainly do with GPS, so I'd be interested to see.

lol very cool. Looks like you are reflecting your wireless signal into your primes antenna. Forcing it down the throat so to speak
Cool Parabolic effect. Aluminum foil is great for that.
Even seems to work somewhat with anti-static bags.
WTF!!!
If this is really true then i'm even more glad i returned my unit. So for my 600€ toy to work i gotta get a 1€ foil-roll, ASUS are you kidding me?

It doesn't have to go down the back. I have it taped on now nd it goes from the top edge of the screen down. You have to move it from side to side to get the best signal. Again it does not need to go down the back, but to find the best location I originally had the foil going over the back.

Very cool PolishPoet. Yes I imagine if you had it in some sort of Parabolic shape. You could increase / direct the signal even more.
hahahah i love this.
Make a plastic frame with aluminum in it and you can clip on top of prime. Sell them and you will be rich!
It appears to block/degrade GPS signal. I'm getting 0 now instead of 2-3 by the window with the foil on. But wifi definitely improved.
Works particularly well holding a DVD in place. I guess they are super smooth and reflective so it makes sense.
Mixed result for me. 1.2MB/s with the foil then 5.8MB/s without the foil and then 6.4MB/s with the foil again.
If I use Wifi analyzer as soon as I hold a DVD in place I suddenly see about four other networks that disappear as soon as I take the DVD away. Happens every time without fail. Signal goes from ~70dB to ~55dB

I was tired of my gps not working with the dreaded spinning circle so i decided to to try to fix it on the cheap. Take a little piece of aluminum foil and jam it between the 2 gold conductors on the right side of your bolt when the bolt is upside down looking from the back. This helps conductivity between the actual gps and foil amtenna on your battery cover. It now takes me 4secs to get gps lock with 10 satellites with gps test from the market. Hopes this helps you too!
FYI the other gold conductors on the top are for the antenna for 3g and lte...

Can you take a picture of what you've done? Curious to see it, and this could probably be improved upon as a 'hardware hack' to improve reception and gps...
Also, grab the speedtest.net app, and do a few trials with and without. Does it make your data go faster?
It ain't pretty but it works for me...
Haha, slick!
The foil on the left in that picture might not be doing anything, as its about the same size and shape as the foil that's built into the cover (painted black). Nice work though, I'll try this out myself and see what happens.
Do any speed tests?
Tried this mod and walked outside and still **** gps.. can't even get a lock lol.
Try something better than foil, aluminum is not an ideal conductor....You know those $.99 stick on gold foil cell booster things? I wonder if one of those, modded to contact the contacts on the case, would make a difference.
...
If you want to get quicker GPS locks I suggest the steps in the following post.
http://forum.androidcentral.com/801754-post32.html
Also I haven't experienced the slow GPS lock time in newer roms.

What do we have here? A discovery I made on BriefMobile.com about an extreme loss of signal while using the HTC EVO View 4G. As sad as this is, it is true. I have embedded a video I made describing and detailing this problem.
Can anyone duplicate this issue? If so, please explain in detail what is going on, and then go ahead and send you complaint to HTC and see what they have to say. I have already done so and am waiting on a reply, but if anyone else wants to join me, please send this video along with any others to HTC and mention where you found it first.

Huh? You tell him that's dumb but then you make a dumber statement? Honeycomb does work in portrait mode. The only native app I"m aware that forces landscape is Market.
(Owner of an HTC View and Acer Iconia)
I was able to reproduce the problem with the bars on mine, however it didn't really seem to cause a performance hit for the most part.also, except for one hiccup, I have stayed consistently in evdo on the 3g side since my last reset.
Also, I have the official htc case from sprint, and in the case I don't really se e the signal drop. However, in a stupid design flaw the case hinders the speakers.
just curious. why would a case make it better? wouldnt it make it worse? I see this on both the flyer and view.
Just ran speedtest in portrait mode with around 950K download and 640k upload Average over 3 runs. Land scape had a 400k average download and 300k upload. Then back to Portrait with a 950 k download and 670k upload.
It is Def a performance Hit holding it with 2 hands in landscape. Holding with 1 hand in landscap with hand supporting bottom of tablet has no effect. That is the way I use it as I'm using my other hand to navigate. Only time I use 2 hands is when typing or reading. But it is an issue, though probably won't be able to be resolved. Your hand isn't the best conductor. There Just needs to be a label like on several of my other phones that say, "Holding in this area may reduce signal strength." This really isn't a big deal and can probably be found in some sort or another in every device out there.
Yes, Placing your hand over a wireless antenae may result in reduced signal strength. This is nothing new in wireless devices.

If the issue was similar to the one on the iPhone 4 then I was hoping the tpu case would act in a similar manner as the bumper did on the iphone 4 thus improving reception.

Indeed. Antennagate was such a big deal because it was Apple making a large design mistake and was causing dropped calls. Two things we certainly don't have to worry about. Thanks to Korey for noticing the issue and bringing it to our attention.

The problem with the Iphone was Pressure, adding a case fixed the problem as there was no longer direct pressure. There is No Such Issue with the View. It is not a case problem or lack of one. Having or not having a case won't make a bit of difference. My View acts the same wether the tpu case is on or not. It is an interference problem caused by covering the Antennae with you hand. Could be a crappy antennae, but it's not the same issue Apple was having.
For instance I can place my hand over the tablet in that area without touching the tablet and the signal strength will decrease. This IS NOT an Apple Like issue.

No, but it is the placement of the antenna in such a critical spot...
Picked up a grey 32GB at Best Buy yesterday. Got home, charged and then connected to my wireless: Netgear WNDR4500. It connected but said I was at -1mbps. Minus? Reset the router, restarted the tablet/computer/dsl gate/etc. Still -1mbps.
I remembered where the antenna was from Anand's teardown so I moderately thumped it with a flick of my finger (like playing paper football with the triangles). As soon as I did BAM! 65mbps! Seriously? Should I keep this thing or take it back?

might as well keep it...it'll be under warranty if it goes again....and you never know if there's more stock available.
It shouldn't revert again most likely since if the pogo pin antenna thing was stuck in the down position it is now in the up position with no way of being pushed down again.
I concur
Modded by MBOK
I would carefully evaluate the unit to make sure EVERYTHING else works to your satisfaction: audio, haptic feedback, screen quality (not too yellow, good colors, solid text), GPS (to whatever extent it matters to you), microphone, touchscreen, etc.
If everything checks out, then consider keeping it. I'm faced with the same sort of decision myself. I have three sitting in my house that I'm trying to decide between (or return all of them and get a different one entirely, or even just give up):
1. Great screen (excellent temp, great colors, very solid text) except for one stuck pixel, decent haptic feedback, but a vibration from the speakers at full volume, non-functional GPS, weaker wifi.
2. Good screen (a little warmer than #1, colors are good but not as much detail, text decent but not as sharp) but a little light bleed, great GPS (locks quickly to many satellites indoors, as many as 12/14 outdoors), stronger wifi, but broken haptic feedback and stains on the backplate that I can't remove.
3. Horrible screen (whites are a dingy yellow, color is washed out, text is pixellated), non-functional haptic feedback, good audio, good GPS and wifi.
All three are BCs and 0214 hardware builds. #3 is clearly going back, but with #1 and #2 I have to choose between the best screen I've seen on a Prime and the rest that's wrong with it. Not an easy choice--I can see details in images on its screen that I can't see on #2.
My point? As Forrest Gump would say, you never know what you're gonna get. If you return the one you have, you run the risk of getting one with more of a problem.

Admittedly off topic but did you buy these all from 1 place? We are clearly in different leagues as I would not have the balls to return three of these to the same vendor not to mention explaining the $1500 in charges to the credit card to compare screen colors to my wife.
Could be the pogo pins... if the SN starts with BC0CK it has bad hardware probably
Last night all was well. It is a BC but I've not heard/read any bad BC stories unlike some bad C stories.
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.

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.

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

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.

Looks like it close to the location for the Easy Wifi Improvement Mod only with the added wire.

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....
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.

YOOOOOOOOOOOOOOOOOOOOO
Make a thread tomorrow when you get it back. And tell US if it improved.
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?

Where did you get it from? My wifi signal in my bedroom is terrible and moving the router doesn't seem to be an option

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:

Why didnt you just tether to your HD2?
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.
