Because the other thread is getting way too big and contains alot of useless posts, I started this thread for FACTS only and "scientific" research. I will update this post (or the second) with findings and possible solutions that are given in this thread.
@mod, maybe this can become a sticky?
Please read before posting to keep it clean!
Please don't post:
- Your testing results without a succesful driving test because we have enough of them already
Test protocol:

- Your conspiracy theories, just wait what ASUS has officially to say
- Posts with no additional information (thus which has been said already by another user, or something like "thanks")
- Posts telling people not to whine and live with it
- Useless discussions if ASUS did or did not gave an official statement
- Useless discussions why ASUS removed the GPS from the spec sheet on their USA website
- Posts telling what you are going to do with your Transformer (return it etc.)
Please do post:
- Proposed fixes which have proved to work before or which have a good scientific backing
- Test results of these fixes (we don't need hundreds of them... 2 - 3 are enough)
- Other significant details which can help to come to a solution
The problem:
- The Transformer Prime (TP) can't hold a lock on GPS satellites or can't even see them and WiFi is relatively weak.
So what do we know already?
- The GPS chip is a BCM47511 Broadcom chip: http://www.broadcom.com/press/release.php?id=s548713
- Antennas are located in the top left corner (looking from the back): http://forum.xda-developers.com/showpost.php?p=20923418&postcount=1
- Extensive testing by users showed that the TP is losing lock very often during movement and accuracy is highly fluctuating
Possible causes:
- All metal back of the TP
- Firmware/software bugs
- Bad/weak/cheap antenna
Proposed fixes (not confirmed working):
- Changing the gps.conf file:

Proposed gps standard test protocol is at http://forum.xda-developers.com/showthread.php?p=20878091#post20878091
Seems to be a new firmware downloading this morning
This might be a fix.
Version 8.8.3.33
FCC information
If you're interested in digging around the FCC's website for pictures and reports:
Website here:
http://transition.fcc.gov/oet/ea/fccid/
Then enter:
Grantee Code: MSQ
Product Code: TF201
The first row shows WiFi-related information.
The second row shows Bluetooth-related information.
Both have very interesting diagrams! Despite them being either WiFi or Bluetooth related reports, they have some cool diagrams of the Prime.
GPS work-around - via wifi
Another work-around (in addition to bluetooth) is to get gps information from a cell phone and transfer to the Prime via wifi.
I've installed and tested TetherGPS and it worked perfectly. There is a lite version available for free on Android Market but it has time limitations. I tested with the lite version and then paid $2.99 for the full version. Here is the link https://market.android.com/details?id=com.comptonsoft.tgps&feature=order_history#?t=W251bGwsMSwxLDUwMCwiY29tLmNvbXB0b25zb2Z0LnRncHMiXQ..
I love how everyone wants their posts to be stickied
Samsung Galaxy Note, which succefully works with GPS and GLONASS, has the same Broadcom chip, thus it is reasonable to check the GP related files from him.
The latest 8.8.3.33 firmware update seems to have definitely improved things... For me at least anyway. I just updated and took the tab out onto my balcony (where it previously was unable to detect ANY satellites at all). Within 20 seconds it located 14 satellites and locked to 10 of them. The connection strength left much to be desired, but alas, I had achieved a lock.
The update also updated the GPS version from 5.8.12 to 5.8.13, so a change has definitely been made.
Sorry, I haven't done a full test as required in the original post, but given the firmware update, I think that this information is worth posting regardless.

Stepping outside onto my balcony gave me this, where previously it would not pick up anything. On my last test, a 45 minute drive, no fixes were achieved, with a maximum of 6 satellites detected.
Version numbers here. I did not take note of the WiFi version before this update, only GPS, so if someone could make known the 8.8.3.29 WiFi version that would be great.
Any others who are able to update and do a more comprehensive test, please do so.
Edit#2: With WiFi assist turned off I was still able to go outside and achieve a 8/13 fix within seconds.. though that's probably to do with the aGPS data being saved from the previous session.
obvious observation, but this does have a factor on GPS tests:
The orientation of the GPS antenna has a great deal with how it performs. Because over half of it is shielded by the aluminum backplate, it needs at least part of the front screen facing the sky to get a good reception.
as i am reading the specs of the GPS module. i'm reading GPS with combined GLONASS support. backwards compatible with old drivers.
is it using both systems?
about the problem. the chip does most processing itself. it leaves the final interpretative task to the CPU. The TEGRA 3, wich does it's own scaling. has the GPS been tested in several performance modes?(battery saver/normal etc) it seems that this last task isn't getting done properly.
with ICS requiring different drivers. (at least on devices as DHD) it seems most likely they're using an old compatible driver for 3.2 honeycomb. and await ICS before using latest drivers improving signal and calculation transfer to the TEGRA 3 (unsupported in old driver?)
i find it hard to believe that it's hardware related, FCC tests and why buy a receiver put it in and sell it, disable it. leave the receiver out in the first place. (what about certifications that have to be re-done to allow it without GPS receiver?)
if looking troug GPSCONFIG.XML from asus transformer Prime dump. there's typo's in the descriptions. A LOT of different arguments are there compared to code found online (cyanogen for samsung P4. etc.)
don't know what PPM means in the frqPlan. cause only the 2ppm is not commented. the 100 PPB and 300PPB are commented. RFType being used is GL_RF_47511_BCRM_EXT_LNA. in commented section it says RfType="GL_RF_BARRACUDA_EXT_LNA"
seems really messy. and that's just a config. (found in /etc/gps/gpsconfig.xml)
hoping ICS with better drivers is the fix

this may be the answer and cause here within your post. it makes the most sense and further back up claim of it being software/driver issues. great find! ICS may be the key to solving this whole ordeal.
At this point it looks to be a hardware software combination I cannot even lock a satellite after the update......

Possibility..
But with the current bootloader status, we can't even tinker with GPSconfig or other drivers to see if it'll fix the issue (like they did it with Acer Iconia and few other android devices).
Another reason for skepticism..
If your theory is correct, it really boggles my mind on how Asus is reacting & responding to GPS fiasco. If s/w or tinkering on drivers can solve the issue, Asus doesn't have to react by "removing GPS from specification" or calling it "bonus feature".
It's a possibility, and I'll be grateful if it is.. but it is leaning more towards hardware issue.

Same boat here. GPS was working pretty good for me before the firmware updates today. Now I can't get a lock at all, I let GPS status sit there for 30 minutes... never even saw a single sat.
My GPS seems to get an initial lock faster but is still unstable after the update. Even without being moved, receiving several satellites with a decent fix, it will suddenly lose everything and then start searching again. I had this same problem before the update. I realize the signal strength is marginal, but to just dump everything and start over is not acceptable. A drive using google maps was the same as before the update, resulting in many signal losses along with loss of position. This marginal operation is with the Prime on the dash directly under the windshield with a decent view of the sky. Other devices I've used do not have this problem. So in my opinion, it is reasonable to say Asus has not yet solved the GPS problem.

The Lite version foreclosed 100% of the time I tried to start it AND did not provide widgets it said it would. Version on my phone had widgets and no FC issues.. WTF
Asus of Taiwan confirmed that it is Hardware issue (backplate). Oh, and they aren't planning to do anything to rectify the situation since "they can't do much about it" (except change the design of the back).

While it may seem like (and very well may BE) a stupid question, I'm not 200% sure one way or the other.. until recently I guess. Read on..
Last night I flashed to DCD's 2.10 ROM with 3.27 radio and go to test Google Maps. I see "GPS Activated", but nothing's picked up, no satellites. This seems like it would mean I'm probably NOT working with a Rev A ROM.
Well then I go from the regular old IE/PIE to Opera Mini 4 Beta 2 and speed test from dslreports.com/stest & mobilespeedtest.com... From dslreports I get "too fast/unstable" (whereas before, with PIE it would load "fine" and average about 600kbps) and from mobilespeedtest.com I get *2.35Mbps* (which I don't think is right/even possible. is it?)
I guess the ultimate question is - Is DCD's 2.10 ROM with 3.27 Radio running EVDO Rev A/GPS or not? Again, I know this seems stupid, and probably is, but this is place to come ask questions so I figured why not. Also, is it really possible that I was getting 2.35Mbps? I've tested a few other times with some read higher (2.6Mbps) and some a little lower (2.2Mbps) but I just don't trust it
well, theoretically, it's possible that you're getting those speeds. I personally doubt it, but it's impossible to say for 100% certain.
on the GPS thing: the first time, it takes a long time (some say as long as 20 minutes) to get the fix the first time, since it has to download a lot of data from the GPS sattelites to get a fix. some have better luck doing that outside. for me, it worked inside, but it did take a long time the first time, and then it all started working.
However, I don't like to harp on a repeating admonition, if you'll go back the last few days you'll find a plethora of posts on the subject that will tell you a lot more than I can in one short post.
So, short answer: Yes, you have Rev A and GPS, but you may not notice amazing speed differences with Rev A because it depends on the infrastructure of the local station and the GPS takes some time to initialize to start with. After the first time it'll get better.
My understanding is that Opera Mini uses a proxy to optimize data for mobile devices, so you're likely to get false speed test results through Opera Mini. PIE or Opera Mobile will give you more realistic speed test results.
Any other thoughts on this?
The leaked ROM that DCD is based on includes GPS. It doesn't include Rev A. The official release is supposed to include both, but Sprint has had unexpected difficulty with Rev. A, so we'll see.

RevA is part of the 3.27 radio, not DCD's roms. The new ones won't work WITHOUT 3.27, but that's where you're getting RevA

OK, thank you. But are there any browsers (not using proxies - Opera) that'll fully utilize Rev A and not crash? I love Opera, you just can't play YouTube/flash videos. And while you CAN play those videos through PIE (and I have no issues playing them), the browser itself stalls out and is very slow and clunky.
REV-A and you;-)
The best way to tell if you are on REV-A is to install WMWIFIRouter and ICS or tether to your PC in some way, and go to speakeasy.net/speedtest and run your tests. You may not even be in a REV-A coverage area, but if so then your download will not change so much but your upload will be above 200k or more if signal is good. REV-0 upload speed is max 153.6k, REV-A is 1.8meg.

Correct, Alltel implemented Michigan EVDO as one of their first, before the DOM-A card was released, and the later markets like Louisiana and Kansas much later, after the DOM-a release, so they got DOM-A cards but did not have VER 4.01.106 Nortel software/firmware yet to put in them so they were REV-0 anyway but upgradeable. I am not sure which newer markets have updated as it is available now cause we are on 5 in VZW land. I am sure Michigan will swap their DOMs in but bet they have not yet, so you are right.
P.S. I know this stuff because I was NT NI and put most of it in ;-)
I am in a Rev. A area (Austin, TX) and have no speed increase, nor have I heard of anyone with a confirmed speed increase. Where is the evidence that people are getting Rev. A speeds? If you are, please post a screenshot. I know the official release is supposed to include Rev. A, but I've seen no evidence that the leaked version actually does. My speed tests have been consistent with what I was getting prior to the new ROMs, and others have reported the same.
You have to take into account that you're using RF not a direct connection, and that those max speeds include overhead and not raw data throughput. Rev A isn't some magical speed increase, it relies on your signal to the tower. Just like how you can get less than 54Mbps on 802.11g due to signal conditions, you can get less than the maximum data rate with EVDO.
In fact you can never actually get 54Mbps, just like you'll never really get 3Mbps+ with Rev A. Rev A actually builds directly of Rev 0 and adds some new modulation techniques that are used in conditions where the signal is good enough.
Then, you still can't be sure your phone is provisioned for Rev A, which it probably isn't because your carrier does not officially support that service on your phone yet.

I am on Sprint. I am in one of the first areas that deployed Rev. A. I speed tested my EVDO connection before & after the upgrade with no discernible difference. The most noticeable speed increase with Rev. A should be on the upload, which has not changed at all. In fact, nothing has. This issue has been discussed across multiple forums and still not one person has posted evidence that this ROM activates Rev. A. Again, I'm not trying to be argumentative, but can you point me to any evidence that this ROM contains Rev. A? Sprint never said this leaked early build contains Rev A, only that the release build would. People assume it does because the release build was promised to, but all those that have tested it that I'm aware of have not shown a speed increase, either in upload or download speeds.
From the Engadget Mobile article about the leaked ROM: "Rev. A -- a feature promised by Sprint to be enabled at some point in the future when the Mogul was first released -- is also apparently going to be prominently featured when this update officially hits, but it's either flaky or switched off altogether in this particular build while the devs are still hammering out some last-minute issues." Just as I said in my first post in this thread.
Source: http://www.engadgetmobile.com/2008/01/26/new-sprint-mogul-rom-leaks-out-gps-support-and-all/
It is important to note that if you are using Opera Mobile for your speed tests the results will be misleading as Opera Mobile uses an intermediate server and then renders a "view" of your webpage and transmits it to your phone. So when you speed test using Opera you are speed testing the intermediate server NOT your phone.

Photoshop! Just kidding, thanks, that's exactly what I asked for. I (and Engadget) was wrong. Do you get those speeds consistently? Anybody else getting those kinds of speeds, especially, on Sprint?
Hi all,
There's no doubt that the Touch Pro/Fuze GPS is lagging. I was comparing it with my imate 8502 today and doing a side by side test, the Fuze is consistently at least 1 second behind. This is confirmed not only by looking at the map, but also at the GPS coordinate. The imate 8502 is quite accurate.
The question is, imate uses the same qualcomm chipset as the fuze. Is it possible to extract the imate driver to try in Fuze? I'm willing to do it if I can get some directions on how to proceed.

Umm.. when you are driving at 75mph, 1 second is some distance. Furthermore, the GPS lock is unreliable, sometimes it would lock in and sometimes it just wouldn't. It's inconsistent.
Don't you want your Touch Pro GPS to work flawlessly?
Please post a link to an official RUU upgrader for the imate containing the drivers you are referring to. I will port them and see if they are compatible and affect our issue.

Good question, heh. But seriously, a second difference when you're using GPS navigation is a long time, especially on congested streets of a large city.
I'm all in favor of something that reduces the lag, reduces the fix time, and increases accuracy.
What am I going to have to do? Carry my old BT GPS with me, as well as my Fuze? That sucks.
I don't even think "nessesity" is the issue here. All of us just spent at least 300 dollars on this thing.... We want it to work perfectly! I've been waiting for the do it all gps/wifi/bluetooth/wm/speakerphone/washthedishes phone for quite a while - and I expect ALOT out of it. GPS is one of my main concerns; and I've been searching these forums for a week now trying to improve it... so yes, 1 second is enough to worry about. In fact - I can't get any fix - and that's even more to worry about. If you guys are sucessful please pm me to let me know the files up.
Thanks,
BZ.
I have examined the imate 8502 drivers, unfortunatly they use an entirely different method of communicating with the GPS hardware than the HTC drivers, in such a way that a large amount of drivers would need to replaced (as driver xxx is dependant on driver yyy, and so forth)
So far I have not had success booting up with the imate drivers loaded. But am continuing to work on it
Main problem is differing OS driver design. On Raphael, rilphone.dll provides interface to Radio ROM, gps driver sits on top of RIL and provides communication between RIL and HTC GPS Intermediate Driver. On imate, TaiServer.dll provides RIL, gps daemon provides communication between taiserver and stock microsoft GPSID.
So, not sure how lucky we are going to be porting those drivers, as much of HTC's software is based on communication with rilphone.dll, and those apps will all break.
Da_G, I want to thank you for releasing such crucial drivers. Lots of ROM chefs have used your great driver extracts and you should get a credit on all their ROMs. Great job you are doing.
I was wondering, could you give your take on the Raphael video drivers? What is the main problem with them and what's keeping us from using Raphael's video hardware to its full potential?
No sweat, I don't do it for credit, I do it to get better use out of the device I paid good money for And learning. Knowledge is power! Spread the wealth! So forth and so on!
Anyway, moving along..
I have tested raph driver 1.43 (xperia), 1.90, 1.95, and blackstone 2008.6.25
Performance goes as such from best to worse: 1.95, 1.90, 1.43, blackstone
There is much potential optmization to be done in regards to the video chipset, but the simple fact of the matter appears to be that the optmization was not done. For example, with the 3d drivers, some roms include hardware support (d3dm_ati.dll) and some use the microsoft reference drivers (equivilant to software rendering on the PC), some use the HTC reference drivers (again software rendering but optimized for performance)
Problem with video playback and 2d interface functions is that only very basic acceleration is included, advanced acceleration features are simply not coded in to the driver. Unfortunatly on my end there isnt much to be done, either we get our hands on drivers not coded by htc (like the imate drivers) and try and port the entire set (not terribly likely to work), or we get our hands on some HTC coded drivers that include proper acceleration support, and drop them in as replacement for current drivers. Adding in the features ourselves is not practical without source code and chipset documentation.
So for the moment, in regards to video drivers, the best we can do is to keep an eye out for phones with similar chipsets (qc msm7xxxx)
Best performance I have seen out of any combination of the drivers is roughly what pfcsabre shows here: http://forum.xda-developers.com/showthread.php?t=448268 give or take. That's with the 1.95 driver w/1.43 HTCmdp.dll
Rest assured i'll be dismantling every ROM i can get my hands on with a similar chipset, looking at the graphics drivers

Very interesting Da_G. Yours is the clearest explanation of the video driver problem I have read. I will definitely watch your posts to see what you come up with. Your work at xda is really appreciated
I just want to thank Da_G for even trying. You know we all appreciate and continue to support your work!
I wanted to add another strange observation of mine regarding the GPS. I use Garmin XT on my Fuze and I notice that the signal bar strength is DIFFERENT if I connect directly to the com port vs going through the Intermediate Driver. The direct com port connection usually yield stronger signal (as displayed by longer bars), and also produces random spikes on some of the bars. With the Intermediate Driver, the signal seems low and 'smoothed' out.
Don't know what's going on...
I just came back from Hong Kong and I have several GPS problems with my Fuze. They really need to fix this thing!
Here's the story:
Had a vibrant, put Axura (Axura 205 Vibrant) on it. Worked great for many many months, until I broke the screen. I tried to replace it but that's another story.
Fast forward to now, I have a new Vibrant, with the same ROM on it, (flashed from stock).
I have tried 6 or 7 different ROMS of various release (Froyo/GB), but the GPS never shows satellites. I have done the access LBSTest fix as suggested elsewhere in the forums, but still not seeing satellites.
On my old phone this specific ROM (Axura) worked great. Same ROM, another phone, doesn't work.
It feels like the gps hardware is bad (I bought the phone used) but my business partner's phone does the exact same thing.
ANY diagnostic steps or outline would be great! I don't know how to determine if the GPS hardware is functioning properly or not. A link, list or other from someone who has dealt with this before would be a wonderful help.
THANKS!
(The only odd thing I have noticed is the stock rom won't connect to any cellular networks. Putting Axura (or any ROM) corrects that issue.)
EDIT: I should note that enabling "Use wireless networks" allows some data to be used, but I assume this is based off of hardware mac addresses of the wireless routers and google's location database rather than actual satellite data
I should also note the manufacture date is 10.10 and the current modem is JK2.
I have been researching various fixes (in spite of the anomaly stated above) and it seems the hardware soldering fix only relates to pre 10.10 and suggests a modem higher than JI6.
I am tempted to try some other ROMs but have exhausted my attempts and feel maybe this isn't something I can fix anymore. Help still appreciated.
sounds like you'll need to open it and do the HW mod for the GPS antenna contacts to be firm together, I used a piece of shaped plastic to keep the tab in an elevated position so it wouldn't lose tension after its snapped back. then DL heathens GB GPS fix , it works awesome for me, best GPS lock ever
Oh an one more thing, Aurora isn't the best choice of ROM, unless that's what you like. JMHO
Thanks. I'll do both, I am kind of apprehensive about soldering the gps, I have broken things before, although I am ok with a solder gun.
Any suggestions on ROMS? I am open for them, have tried a few (Cm7, SIMPLE, Revolution, + others) but since I couldn't get the gps to work I assumed it was rom related.
You might also try a new modem with a Froyo ROM. Any of the KAx or KBx modems with a Froyo ROM should be an improvement.

Something I've noticed with the hardware fix is the author of the post here states that the manufacture date is 9.10 or before, and mine (10.10) shouldn't need it. Is this true?

Running KB5 now. Which app do you recommend for seeing what/how many satellites have a lock? The one I am using now (Gps Status) just has a spinning icon on the bottom, with no info.
I am at a loss as to why this phone won't lock. I'm willing to paypal anyone who has the time and gumption to assist with a true repair.
Edit: Just went outside with the GPS Test app (disabled use WiFi for location) and it could "see" 1 satellite, but was using 0. Does this help in giving an idea as to why it won't work?
Maybe the antenna issue can still exist post the 9.10 manufacturer date.

THIS IS ALREADY INCLUDED IN THE PRIME ICYLICIOUS ROM LOCATED HERE
THIS IS NOT A FIX FOR FAULTY HARDWARE!
Attached at the bottom of this post is a CWM flashable file to help with the known GPS issues with our beloved Prime.
When creating my ROM, I noticed that Asus had left out the gps.conf file completely from the ROM, which exists in every other Android ROM I've come across.
In the zip file is a tweaked "gps.conf" and a tweaked "SuplRootCert".
Directions are as follows.
Download the zip file from the attachments in this post.
Boot into CWM
Clear Cache and Dalvik Cache before flashing (your first boot after clearing will be longer than normal)
Flash file in CWM, and reboot.
To calibrate your GPS download GPS STATUS, install and open. Go into settings, "Display and Tools"....tick "keep screen on". Go into "tools" click "compass calibration" and follow instructions. Once calibrated go outside in an area clear of obstructions. Make sure GPS is turned on in "settings". Start up GPS status and let it sit for a few minutes (if GPS icon does not start blinking, click on your quicksettings to bring up the quicksettings bar, then click on the GPS Status app screen). First time starting the GPS will take a few minutes to lock. After they're acquired, your GPS should lock quicker the next time you start your GPS.
These are my results from THIS THREAD following the directions listed above.

Video with NO Wifi Connection using the fix:
If you're not in the USA, you can find the files you need HERE, but you'll have to manually extract the files from the zip, and copy them into the appropriate directories!
Credit for the gps.conf file contained in this patch goes to:
crypted
Asus uses /etc/gps/gpsconfig.xml
you reference the android gps.conf, which i think was a android3.x default, and no longer comes with ICS.
with gps.conf you get a lock based on wifi+internet time, and not actual hardware gps, which the gps/gpsconfig.xml is for.
so gps.conf virtually just looks good, because you previously activated hardware GPS at your home with internet connected. This will not help if you have no wifi available, or if its an unknown AP.
gps.conf is just a false hope for hardware improvement, but is pure internet data based.

gps.conf is a quick lock based on wifi and known internet AP routers, so it can point out your coordinates, not a hardware gps fix.
but yes, it can help in wifi-lock if wifi is also achieved, i do not deny that from here, but its not fixing any asus hardware issue.

Uploading a video right now. Never said it fixed any hardware issue Dexter, just that Asus had left out files that EVERYONE else is still using even in ICS, along with the cert file we've been using for a long time with the A500. Moscow said he thought you might have been the one to come up with the cert file...is that true? If so, my apologies for not giving you recognition.

I actually had to reboot just before the test. no wiping of anything, but of course that's already included in my ROM, so you might want to wipe dalvik, and cache if you're using it with another ROM, as that might help
EDIT: have modified the instructions, and thanks for pointing that out.
yeah the video looks official. those sat's locked quick as a mofo. well you know the next proof people going to want to see. actually driving and seeing if satellites can lock and hold the lock for navigation purposes like in Google earth or whatever.
seems legit. hopefully this is a viable fix and can be improved on further down the road.

Like Dexter pointed out, this doesn't fix any hardware issues. All I did was put a tweaked version of the file that Asus should have put there in there, and added the cert file that most don't include.

If this is 2 tweaked files why can't we download unzip & place the 2 files with Root Explorer & bypass the whole flashing process if your only rooted? See any issues with this?
If not what are the directory paths for each?

Hey Guys, just thought I would pass this info along that I found really interesting. I have a friend who recently purchased the Archos G9 tablet, which came with Honeycomb. His Wifi/GPS worked great during this time, but after updating to ICS, his wifi signal is considerably weaker,(even drops connections) and he can no longer get a GPS lock! Also, it seems to be a widespread problem for the recently released Archos devices. Before ICS, they had no wifi/GPS issues, but right after the update, numerous owners are reporting that they can no longer get a GPS lock, or they may only pick up one satellite even when outdoors, but lose the signals as soon as they are in motion. Now this seems to be one hell of a coincidence don't you think?? Can anyone confirm that GPS and wifi was better for them before updating to ICS?? I also attached the forum link for you guys as proof of the ICS update issue. Apparently, Archos is working with Google to determine the cause of the GPS/wifi issues since the update. Now I am not saying that ICS is the root cause of our issues, but it is possible that it is compounding the problem with the metal backed plate on our Primes. It's well known that Asus installed two wifi chips to compensate for the metal backing, but what if the ICS code is also hindering on the wifi/gps performance??

Interesting read for sure. Well hopefully the big surprise from Asus is a new firmware with most of the issues fixed. Can't wait to see what they have instore for us. Then can't wait for diamond to integrate the good parts into his rom so I can flash it =)

My Nexus One on unofficial ICS has the same wifi reception as on gingerbread. This being said, it also uses almost the same kernel and the same proprietary drivers as on gingerbread. My point is : ICS is not the problem. IF there is a software issue that can somehow be fixed, it should/must be done in the kernel/driver area.

Well.. I figure I have to reply to that post...
I have a Archos 80 G9 that I bought after reading too many horry stories on XDA, my heart was really set on a ATP but I figured that I would get a tablet that would a) be upgaded to ICS and b) I wouldn't mind giving way once the dust had settled and bugs have been ironed out.
I have been following these threads since the ATP hit the shelve, but they have not reached the ME where I live and after reading here there was now way I would buy an import without warranty support... So as I say I bought a cheapo Archos just to get me by.
I can now confirm the OP's statement. the Wifi problem is in ICS (can't say that about the GPS as I've not tested). I've read about you guys opening the boxx and from the start upgrading from HC to ICS so you've never seen the ATP running on HC. With the Archcos I had a good 2 month running on HC before the ICS upgrade so I can sure see the difference. The main problem I faced with the Archos on HC was anything using video - Youtube & Skype come to mind off the top of my head - they were both un-useable, but I figured you get what you pay for and let's see what the ICS upgrade brings.
Low and behold, after ICS, my WiFi is crap in comparision to before, I can't put my fingure on the issiue, but it's sure weaker connection, or doesn't connect automatically, or just won't allow me to load a web page! In addition, the touch screen is way less responsive in that I'm having topoke and poke again at the screen to make anything happen - that may be because the WiFi is crap so I don't have internet access, or it may be a touch screen issue. Either way it feels like I've jumped out of the pan and into the fire - no video before (now that is better), but I never know when I have internet access.
Well spotted OP... if there is anything I can test from here, let me know OK

That's exactly what I'm thinking. The new firmware fix could possibly address the WiFi issues which seems to be also caused by ICS. Maybe this is why Asus are returning RMA's with the same issues, could be that their dual WiFi components are working as intended, but ics is causing signal issues! This will be great news if the problem can be solved through a firmware update
Well if the wifi gets fixed on this tablet I will have zero complaints what so ever. GPS bothers me, but not much. Ill probably try to fix the small light bleed I have.
......and the thread blows up with speculation.... lol
Sent from my Transformer Prime TF201 using Tapatalk
I had GPS problems on the Prime before ICS. While there could be something in ICS that hinders GPS reception, I think it's well established that there are hardware problems with the Prime with respect to GPS and wifi reception.
My wifi seemed to be the same on HC as ICS; I haven't had any problems before or after upgrading.

Nah, it's a myth. It is always a "s/w" problem... You should know that by now if you read this forum.
Ok, GPS issued is confirmed on the Archos G9 after my friend updated to ics. He didn't have the GPS test app prior ics, but on honeycomb he had no issues getting a GPS signal in seconds, an he confirmed that it worked in his car while driving to an from work. Now using the GPS test after updating to ics, it takes him in average of 2 minutes to pick up 3 satellites while outside, but he loses his signal when driving. Also, he has freezing issues when browsing an random reboots at least once a day. He's coming to my home now to do a wifi speed comparison, but he stated that he can no longer watch netflix when he is in his bedroom, while his router is in the living room(seperated by two walls). This to me is just one heck of a coincidence.
My tf101s wifi got really bad after ics update. Range was shorter, and disconnects.

I can see ICS maybe affecting wifi. as far as GPS, we know the components of the deadly cocktail already. software is part of it but doubt it bears more weight than design issues on some units. I do believe wifi can be tweaked or optimized even more so. I get good wifi reception n all but anything could be made better.
we do have an update to .16 which is due anyday now. I would've thought we would've gotten it already. maybe tonight or tomorrow. still awaiting the great prime news also. maybe they will announce 5 million units sold in 3 months..lol

I read about wifi problems on original transformer due to ICS as well. Heard asus pushed out an update to ty and fix it yesterday.
[QUOTQUOTE=shinzz;23629090]Nah, it's a myth. It is always a "s/w" problem... You should know that by now if you read this forum.[/QUOTE]
Obviously your joking right? I opened mine and can confirm it's hard ware. Attaching one piece of wire to the wireless connection gives nearly double the wifi performance for me.
I can support the GPS theory for sure... My GPS stopped working completely as soon as I upgraded my Prime to ICS. While still under HC, I could get a lock on 10-12 satellites ... though it took way longer than it should (like a few minutes). Haven't had much trouble with my wi-fi, so cannot tell if it degraded with ICS, or not.
So ICS is still very new and has still bugs in it. I dont see where this is any new information Have some patience. My prime (can only speak for me) is very usable right now and i know that it will only get better over time as software improves. This was the case on all my android devices and will be true for the prime as well.
The difference is that ICS was quite the step for android, a lot of visual changes and tweaks/improvements. So i think we will see a big improvement overall if something like Android 4.1 comes out.
But as i wanted to say this is not really news to me^^ I expected something like ICS to be somewhat buggy I mean look at iOS. 5.0 had the battery bug which is being fixed now with 5.1. This is half a year after the release of ios 5.
Ok, lets pull up a couple of statements real quick. This is a Archos tablet that is having Wi-fi problems after ICS. How does this relate to android? I understand that this is based on the idea of ICS doing this, but they are different companies. Asus makes tablets for their tablets and the Archos tablets is made for their company. The company making Archos could have made a mistake when altering it to make it compatible for the Archos tablet. Also it has been proven that the metal backplate on the prime blocks off the wi-fi signal dramatically. ICS on the prime is already covered as it is. Think about it, why would they make the TF700 with the specific backplate if they knew that this was a software problem?

Also it has been proven that the metal backplate on the prime blocks off the wi-fi signal dramatically. ICS on the prime is already covered as it is. Think about it, why would they make the TF700 with the specific backplate if they knew that this was a software problem?

What are you talking about?? Both tablets are running ICS, both have wifi/gps issues after updating.. I never said that ICS was the cause only... I am saying that it MAY contribute.. Could be an code issue within ICS that doesn't play well with wifi, which is only amplified by the Primes metal backing.
I and others will confirm that wifi an gps was fine for the Archos tablets before updating to ICS. People are also reporting browser crashes, freezes etc. So yes ICS is still a young os an could be added to at least the wifi issue
