Hi,
I have received my Nexus a couple days ago and have a serious issue with the Wifi speed.
It's connected with a link speed of 104Mbps and a "good" signal strength, but it
takes forever to completely load a website. In comparison I have an iPad Air and
a nexus 5 connected to the same AP and they work fine.
For example: to load a website such as seattletimes.com it takes 44 sec. until I see the
first content and once the content is there the tab is still loading for another minute(!).
On my Nexus 5 the whole page is loaded in less than 10secs.
If I connect the tablet to my Nexus 5 via the hotspot function, browsing works perfectly,
so it can't really be the wifi?
Any idea is appreciated!
Andreas
I also find that speed tests do not yield favorable results. My N5 receives the full 50 mbps from my router whereas the N9 seems to cap out at about 40 mbps.

So no one else here experiences problems like these? I have yet to hit 50 mbps on my N9 while my N5 (on 5.0 as well) can hit it every time.
Yeah Wi-Fi seems to have issues. Anyone notice problems with Wi-Fi band? I set to 5ghz instead of auto but every time I reboot it ignores this and connects to 2.4ghz.

I actually have set my 5 GHz to a separate SSID so I don't have that problem. I wish more people would chime in with speed tests...

Actually I can relate to that issue. I have both 5 GHz and 2.4 GHz connections in my home and it's very slow on both networks, especially images take forever to load. I'm sure this is something Google can fix with an update, but it's definitely annoying for now. A simple speed test with Ookla shows nothing out of the ordinary though.
What build version is having the issue? What browser are you using? Try clearing data and cache on the browser you are using. Are there different SSIDs for the 2.4 and 5Ghz bands? What channels do you have selected for the 2.4 and 5Ghz band? Is channel bonding turned on? What are your results from SpeedTest (post the Nexus 5 and iPad results for comparison)?
I have two Nexus 9 tablets and none are experiencing any wifi issues. One of them is running the older build (LRX21L) and the other the newer one (LRX21Q). Just for you to know the only way I got LRX21Q was to do a manual flash with the system image. The OTA is most likely broken for most.

I'm currently on LRX21Q however I experienced this on the initial build as well. I'm using Chrome Beta, but the results are coming from the Ookla Speedtest app. There are 2 different SSIDs for the different bands, and I'm always connected to the 5 GHz band. I played around with the channels for the 5 GHz bands to no avail, so I'm back to auto.
What is channel bonding? My speed tests are as I described above (40 mbps on a 50 mbps connection).
It is also slow on the 2.4ghz band? Have you tried a factory reset? If a factory reset does not fix the issue you might have a defective wireless card or there is a bug in the wireless driver. There is probably a way to run a self test diagnostics on the wireless card, but I do not know of any such tool. Did you update to LRX21Q by the OTA or the full factory image?
Channel bonding works by combining neighboring wireless spectrum to increase your wireless bandwidth. On the 2.4ghz band, the default is 20mhz width. If you enable channel bonding it combines the 2 20mhz bands to create a 40mhz width. Thus increase your spectrum to more data. However, using this on the 2.4 ghz band is not recommended since it can cause interference to neighboring APs. Also there is very limited open spectrum. Mainly channel bonding is used in the 5ghz band since there is more open spectrum to use. By default 5ghz uses a 40mhz width, but newer routers (AC1750, AC1900, etc) have options to use 80mhz width.

What channels have you tried on the 2.4ghz band? There are only 3 non-overlapping channels that should be used. Try setting it to channel 1, 6, or 11. Keep the channel bonding set to 20mhz (that is if your router has that option). Hope this helps.

I don't know how to measure the actual speed on my device, but I do experience very obvious speed problems. The strangest thing is maybe that they're intermittent: sometimes apps respond just fine. And then all of a sudden it takes ages to load web pages, Wikipedia pages, refreshes of Facebook and e-mail. Most of the apps just take a long time, the default Gmail app usually conks out and says that "there's no connection". Even though the wifi dialogue says the connection is fine (quality "excellent" or something like that) and another android device, still on KitKat, has no problems loading the same pages & refreshing the email.
So there's definitely something weird.
But is it the device, or is it something in Lollipop? Because that other android device now wants me to update to Lollipop, but I'm a little hesitant to do that...
https://play.google.com/store/apps/details?id=org.zwanoo.android.speedtest
This app will be able to measure the internet speed on your device. It's best to know what your maximum theoretical ISP bandwidth is (mine is 50 mbps down/up). And be sure to test this app on multiple devices to see if you get consistent results on the N9.
I just updated to L21XR and the issue is still there.
Thanks for the tip. I will try.
But I won't get consistent results anyway, since the phenomenon is clearly intermittent. I tried it again just now: facebook was incredibly slow in showing pictures and the contents of articles. So was the browser when I tried to open the articles there.
I switched off the device and restarted it, and now all is smooth again. But in a little while it won't anymore.
It's as though there's some memory leak or congestion that builds up or something. Terribly annoying in such an expensive device.

The speed test app runs for a few seconds to ensure that it yields the correct maximum bandwidth. This will surely indicate whether you're downloading at maximum bandwidth. Yes it may be inconsistent between tests, but that's what we're trying to prove here.

I get really good wifi results. My N9 gets equal to what my Note 4 and wife's S5 gets. Are you still experiencing this problem?

you have got to be kidding me, now you kids are complaining about not getting a full 40M speed. seriously?!?!?! grow up with hook and receiver 300 baud dialup on a crappy serial interface, and then come back to me with your speed complaints. until then. the tech delivers something that did not exist when you were born 13 years ago.
some of you kids just make me laugh with your desire to buy tech, and then nitpick and pull it apart like you have the slightest idea of underlying tech advancements. oh no, I have screen bleed because I cranked up the brightness to max. oh no, I can't get my home WiFi connection at work. oh no, the plastic case feels plasticky. turn down the brightness, stay at home and buy a case.
as to your WiFi issues, change the damn channels on your router and stop letting your brother's pørñ addiction and neighbors WiFi signal collide on the same channel . geesh.

Something definitely sounds wrong. I just tried loading "seattletimes.com" and it took just under 3 seconds.

Relax there buddy. I have an N5 which outperforms the N9's Wi-Fi, and being an engineer, I'm trying to get to the root of the problem. The device should be more than capable of hitting my max bandwidth as my phone does.

I'm having similar issues, but not so much with speed (although occasionally yes). Often, I will notice my wifi connection shows the icon with an exclamation point over it. I suspect that it means that my wifi is connected but that my internet connection is not a 'good' one. It's not something I've seen on my Nexus 7 or my HTC One M8, both of which run stock KitKat presently.
I was hoping that the most recent Lollipop release would solve this but it seems that a couple posters above have not had their issue fixed.

Hey guys,
it's me and my german Prime again. I want to share some of my impressions and findings with the ICS upgrade after some days of use.
First lets think again about the issues I had with HC:
Wifi range was worse than other devices (speed was way better btw)
HDMI screen mirroring was cut at the bottom
HDMI audio was only on the left channel
GPS not working at all (barely one single satellite)
Boottimes were horribly long (2 minutes or longer)
Bluetooth + Wifi lead to massive bandwidth drops
Touchpad was kinda crappy (two finger scrolling in mouse mode)
Okay, all these issues weren't really any kind of deal breaker for me, I really enjoyed my Prime since the .33 update (before the .33 the touchscreen really sucked)
I got (as I expected) my update somewhere around 8 PM PST on January 11.
The updated installed without any problems in about 10 minutes.
After ICS booted up I did a full wipe to ensure I have as less problems as possible.
Now lets talk again about the pre-ICS issues:
Wifi: Pre-ICS I was not able to connect to my home network due to the Prime not seeing it all. (Range issue)
This is now fixed with ICS. So in fact this means the Wifi range is better now (at least for me). The connection is also a bit more stable.
Both HDMI errors are gone now. Playing 720p and 1080p mkv files with DTS or AC3 sound works perfectly with Diceplayer.
Not a single issue anymore
Touchpad performance is way better now.
I can actually use the mouse mode now for scrolling etc. Nice!
Boottime almost halfed for me. It boots up way faster now.
Wasn't a big issue before, but nice to see they are making improvements here.
As several member here pointed out, the Bluetooth Wifi issue is not a Prime specific issue.
Every single other device I tested had exactly the same problem. No matter if a Desire, Desire HD, Lumia 800, even my Laptop to some extend...
So this "issue" is a non issue for me.
Now to the GPS part: (Please note that this issue is a non issue for me too, I don't care for my tablets GPS, it's only that I want everything to work).
It's actually too cold outside to test the GPS more than two minutes, but after this time I still can't see a single satellite...
So far I never had any kind of GPS lock with my Prime. I am not sure if it just needs more time...
I will test that later.
I tested the GPS for several hours now (actually I just put the thing outside under clear sky and let it rest there for some hours)
It searched constantly for GPS satellites using the "GPS Status" app and didn't find a single satellite. Not even one.
The only reason why I think I don't have a broken GPS chip/antenna is that I saw one satellite back in HC times...
Since then not a single satellite anymore. (Wifi on/off didn't make any difference btw)
As said above, I don't really care, so this totally faulty GPS (it really just doesn't show anything) is a really good point to return it some time later to get maybe a completely new one
I've found also several non-issue related things:
ICS just looks beautiful
Damn ICS is fast! Everything is just that important bit faster than HC. (not that HC was really slow, but ICS is just noticable faster)
The ASUS taskmanager widget just does not work at all.
It just shuts down as soon as you add it to your homescreen. That's a bit embarassing
Some other facts and information:
Do you know about the "Deactivate app" feature? (Settings->Apps->Click on single app) It's awesome!
You can deactivate (like freeze in titanium) almost every app on the prime. Even the system apps.
I deativated quite a bunch of them (about 20) and the system feels even faster now
I just tested my PS3 controller on the Prime. The native (via USB cable) support works quite well for GTA3 or Shadowgun.
Unfortunately the "Sixaxis" app is not completely compatible yet, touchprofiles won't work at all.
The dev already promised a fixed version for next week
The browser performance is really nice No lagging or skipping
After some fiddling around finally browser sync with chrome works too That's really cool! (I needed to delete chromes bookmark data first in google's dashboard, then resync my local chrome. After that the syncing to the Prime worked perfectly.)
So all in all I am super happy with the ICS update. There's still room for improvement, but ICS really made my Prime the device it should have been since the beginning.
My experience with my (DE SKU) Prime is almost the same. Though I had no WiFi issues prior to ICS.
I've only had mine since monday, so I only had 3 days to play with HC before ICS. But even I feel the difference. Everything is just smoother and more responsive. Especially the web browser. And it will actually sync your Chrome bookmarks now. Yay!
I'm exceptionally happy with my device. I bought it to keep me entertained with movies and games during my 2 hours of commuting every day. So far it's been too much fun to play with to get any gaming or movie watching done.
And I'm not sure if it's because my battery is being broken in, but I feel my battery life has gone up since ICS also.
But yes, Asus Taskmanager seems to be broken for me also. Chrashes as soon as it starts. That's the only negative thing I've seen since the ICS upgrade.
This thread almost convinced me back into getting one... Can you compare the wifi range to anything? GPS I dont care about at all. My biggest gripe is the wifi range. How is it compared to the TF101 after ICS? Or even a Galaxy S2 if you have one of those? Both of them have good enough wifi range for me, if the prime is equal, then I will get one.

well, my prime actually picked up my university's wifi network and had a pretty good signal while my galaxy s2 struggled to even connect. at home, the prime is just a tad slower than my sgs2 when doing speedtests.
Hi Diamondback2010,
I got my Prime and at this moment debating if I'm going to stay with it. I'm on ICS and the issue for me is the skippy WiFi. I have a 50MB connection at home and all my other devices laptops, desktop have no issues whatsoever streaming media to tv however simply being 15ft from the router on the Prime I'm losing connection simply by browsing webpages and they take long to load. I don't have this problem even on my DHD.
For a WiFi only device WiFi is the most important aspect for me and the intended use is for traveling and connecting to different WiFi networks.
Perhaps the newer Prime would be more suitable for my needs that's coming in a few months time unless the current Prime can be made better or these issues I'm having resolved with a firmware update or something.
Also to mention I can replicate screen flickering on the Prime on ICS by using it for a while opening a dozen apps/webpages and tapping the recent items button makes the screen flicker on ICS.
This isn't very good plus the WiFi issue I might send it back, will further be testing today.

As much as I also love my SGS2, I've never felt it had particularly good wifi. So my Prime beats it nicely. Especially when it comes to the data flow from some distance (20-30 feet through 2 walls) where my SGS2 will have data drops using speed test, my Prime will see no such issues. And the Prime will have more than 10db better signal strength than my SGS2.
I know you asked for the GS2 or the TF101 but since I have neither of those I compared it to my HTC Wildfire which it beat quite comfortably.

That sounds great! I know the SGS2 isn't known for the best wifi, but it is good enough to get a connection where I normaly would use the prime. My TF101 is a little bit better than the SGS2. If the Prime is anywhere between those two, I will buy one! You convinced me
It doesn't release here in Norway untill the 30th, but I will get one then. We are only getting the Champagne gold one, originally I wanted the Amethyst more. Any of you got any impressions on the colors? What do you think of the champagne one?

Well I can compare it to my laptop and my Desire HD.
My laptop has a really good Wifi reception and it beats my Prime to death
But my Desire HD is a different story. The DHD does have a better range, but that is due to the fact that we (Virtuous Team, creator of the custom ROM I am running) tweaked the Wifi range way beyond stock levels, which leads to really crappy speeds at such ranges.
So in fact my Prime beats my DHD speed wise too. Only thing you really have to keep in mind, is that the Prime's connection is heavily orientation dependant. If the screen shows towards the router (or the general direction) it has quite a bit better recpetion as opposed to the backside towards the router.
I can't really replicate this with m DHD (at least not as much, DHD has Wifi antenna on the backside under a plastic RF window)
With HC I was a bit concerned about Wifi (only range, not the speed), after ICS this is gone.
One gripe is left, but this has something to do with ICS and not the Prime.
You are forced to have some kind of locking mechanism (pin, passwort, gesture) if you want to use an enterprise wifi with certificates (university network)...
That's a bit annyoing... :/
But it's the same on my Desire HD...

I have just been doing some WiFi tests with my HTC Desire HD (running Virtuous Affinity) and Asus Transformer Prime and this is what I'm not happy about
I have a 50MB connection and the desktop with a direct connection is getting 49Mbps so it is a true 50Mbps connection
Now for tests sitting right next to the router which is an N-series router
On my laptop I'm getting 34Mbps
On my HTC Desire HD I'm getting 18Mbps
On the Prime I'm getting 11Mbps
Now for outside in the garden going through 2 walls about 20ft away
On my laptop I'm getting 12Mbps
On my HTC Desire HD I'm getting 6Mbps
On my Prime I'm getting 1Mbps!
I have done this several times and the figures are consistent - this shows my Prime to be under performing compared to my other devices. I would expect the Prime to perform better than the Desire HD but it doesn't.

I'm not experiencing that at all.. Within 10 feet (or right next to) my router I get over 40Mbps down/5Mbps up (I got a 50/5Mbit connection). This is with a Linksys E4200 v1 router.
20-30 feet away (around 7-10 meters) through 2 walls, I get around 10-14Mbps down/4Mbps up. This is almost the same as my old Netbook (Asus Eee first gen). And alot better than my SGS2.

It's better, but only by a tiny amount.. And nothing noticable for me when I do a speedtest (2-3Mbps difference and just as stable). I have to note, that my tests are through drywall, not brick.

My tests were through brick house walls. Thinking about it its quite amazing that the old Asus 1000HE netbook I have running Windows 7 which I upgraded it with has better WiFi than my Asus Transformer Prime...
I got the Prime for a similar use as the 1000HE for travelling abroad where I connect to loads of WiFi networks. With that low WiFi performance on the Prime I can see I'm going to have problems.
I'm debating to send it back and waiting for the newer Prime which maybe an improvement...

I'd deffinatly try a factory reset if I was you, as a last resort.. Brick/drywall aside. 11Mbps right next to the router is not right unless you got some serious interference going on.
Just trying a factory reset from settings. Would that be the only reset method to reset or is there some other method with a pin?

I believe thats the way to do it yes.. The pin is only for force rebooting the device, not a data wipe.

It's clear that WIFI is causing quite some debate, some people having issues, some people saying it works fine for them...
But often nothing is mentioned about whether they are on G-only, mixed, N-only. How the tests have been done, where the router is and where they were while testing, etc.
At the moment I own a TF101, TF201 and SGS2 and 2 wireless routers so I am in the position to do some testing but am wondering what the best way is. I know of wifi analyzer and speedtest (the app) but get extremely mixed results with speedtest.
On one run it can tell me I have a 13mbps connection, but 2 measurements later it's 5 or something so not sure if that's the way to do it. But what is? I guess wifi analyzer is fine for general info (signal strength) and it seems the signal strength shown on the TF201 is almost as good as on the TF101/SGS2 (also when 10 meters away from the routers with for example 2 walls in between).
If this thread is unnecessary or something, please close it... Just wanted to get some direction and clear way of testing and measuring to finally get an answer how exactly the TF201 performs.
* General signal info: Wifi Analyzer
* Speed measurement: Speedtest app? How many measurements should one take, is it necessary to close the app after each measurements? Or should I transfer a file to/from my pc to the tablets over wifi or somethign, or use a webbased speedtest (and with or without flash interface?)
Any recommendations/remarks?
>WIFI is causing quite some debate, some people having issues, some people saying it works fine for them...
Wifi performance is highly variable, depending on many factors. People tend to think of wifi as "if it works good for Joe, it should work good for me." That's not how it works. It's not possible to have a standardized wifi test that applies to everyone.
>I know of wifi analyzer and speedtest (the app) but get extremely mixed results with speedtest.
Speedtest introduces the vagaries of the Internet, which increases variability. People use it because it's convenient, but it's better to use something that tests only your LAN. Suggest iPerf for Android. Another simple method is to do a large file copy to get throughput (size / xfer time). Do it 3 times and get avg.
Wifi Analyzer shows routers w/ recognized SSIDs, but it doesn't show other sources of 2.4GHz interference. It's better to just ignore it and run throughput tests for each channel.
There are various caveats for setting up wifi: don't use mixed mode, don't use auto 20/40 for 2.4GHz, don't use TKIP/WPA or WEP, do use WMM, et al. All these reduce wifi speed.
However, the complaint many have is (drastically) reduced speed with respect to increased range. That's usually a reception problem rather than a config problem. It may be fixable with a config change, but more likely, it can't. Testing won't solve this problem. Even if you get good results with testing (via changing some specs), it'd only apply to you and not anyone else.
Suggestions:
. Check for and apply any router firmware update.
. Optimize router config per tips found at various sites.
. Try throughput tests. Change channels and experiment with settings per test findings.
. Try a different (new) router. Many routers mentioned in other threads are old draft-N units that may have compatibility issue with certain devices/drivers, especially in mixed-mode operation.
The last is a quick and simple solution for non-techies. Routers are cheap to replace; not so tablets.
Their is no standard test as we all have different routers! My router is fine with the prime! works great super fast downloads faster than my Evo 4g and my brothers thrive

I understand about the variances, I think it's more of a matter of being able to test with multiple devices you own. In that case you can actually compare your TF201 (in this case) and the effects of obstacles/distance on it (again compared to other devices you actually own).
If people say 'well, the TF201 works just as fine as my SGS2' I have no idea what exactly it means... When setting right next to the router? Perhaps the wifi connection is not the bottleneck? etc...
Was more hoping for a good way of simply testing the TF201 performance compared to other devices in my current home situation. But having some sort of set settings might make it possible to compare those results with other people doing the same thing with a number of devices in their home situation
About the different routers, sure... But they all have the same general settings.
The idea was not to find a solution, but merely get a proper measurement of the situation and perhaps draw conclusions based on that.
But I'll check the iPerf app and also the simply transferring an x-amount of data. Thanks for the replies so far!
>If people say 'well, the TF201 works just as fine as my SGS2' I have no idea what exactly it means...
Most people aren't technical. It's hard enough just to get folks to tell the name of their routers, let alone how it's configured, or any other test parameters. Like the 3rd post in this thread. That's the way it is.
It doesn't matter anyway. As said, how wifi performs on one doesn't relate to the next. The only thing that's relevant is how it performs for you. That means doing your own testing, configuration, etc.

iPerf will do that. Have one PC connected to router via wired cable to act as server, and do comparative testing.

Different routers have different performance, even with same settings.
e.mote is 100% correct in what he writes. I'm not the network/wireless guy at work, but I have been following them around from time to time when people claimed that some of "my" systems didn't work over WiFI..
Wireless is a very imperfect medium. First and foremost 2.4Ghz is shared by too many devices. Most of which you will not pick up with WiFi Analyzer. For example, we had a situation where all wireless communication died in an area around lunchtime every day. After alot of work we found the culprit: one of three microwave ovens used by the staff would flood half the 2.4Ghz channels with noise, effectively jamming them.
Also, wireless is a shared medium. That is, every device connected to your router has to wait its turn to be able to talk. If some of these devices are too far away from each other to "see" the other devices, chances are they will try and send/transmit at the same time. This can also severely distrupt WiFi performance.
There are so many variables when it comes to WiFi that I'm usually amazed it actually works as well as it does. And when it doesn't, it's too easy to point at a single device as the culprit. There is usually many factors at play here. It's damn hard getting any mainstream user to understand this.

I agree with e.mote too. There are a couple of YouTube videos floating around comparing a TF1 to the Prime side-by-side. The signal on the Prime seems erratic in comparison. Much like GPS, getting a signal and maintaining it are two different things. I think a lot of people are using the tests e.mote mentioned and calling it good. The throughput test is the only one that tests the sustainability of the signal. Things like web access don't really need a sustained signal to appear to be performing well. Streaming, online gaming, and downloads do. If you're always using your home network and get good results there then Wi-Fi performance probably isn't a big deal for you. It's when you're traveling and using sketchy APs in hotels, restaurants, and airports, that Wi-Fi's really tested. GoGo inlfight is a great test when 100 people are all competing for the same bandwidth in a confined place simultaneously. There can never be agreement on Wi-Fi performance because no two people use Wi-Fi the same way or under the same conditions.
By running the speed tests from the speedtest. net app the new update actually made my wifi speed slower . My connection is 40 / 5m . When I was on firmware. 11.1 I was getting about 5m down. Now I am getting about 1.5m down with the new .13 update. I thought the change log says that it increases wifi performance. Anyone else see slower speeds?
Also to put this in perspective I have my iPhone 4 running the same speedtest app and its getting almost 18m down in the same location as my prime.
Did you try a reboot then do tests again? Yeah the changelog does says it improves wifi on most devices. Still more updates coming though.
Yeah, it increases Wi-Fi performance but for some only and makes it worse for others.
I took mine back to the store earlier today and said I wanted a refund since they got none in stock. The salesman called someone to come over and he asked me to wait for this .13 update, claiming it will fix my Wi-Fi problem. Since I only wanted to exchange, I kept mine. Will report once I am able to update.
Yeah after playing with .13 for over 24 hours my wifi is worse for sure.
My net is 15k down and 2k up.
I live in a condo and can "see" 8-14 other wifi networks. (gads!)
I set mine up to be in the least busy channel
Did this test at 5am to have the least noise
next to router: (2 feet)
14,220 up 2142 down That is the same speed I get wired
Next room over, though 3 walls, bathroom and near a tv, access point, xbox, ps3, wii etc aka a ton of other wifi devices
near side of the room (10 -15 feet away)
13850 down 2113 up
Far side of room (8 feet more) so 15-20 feet away
3896 down 2132 up
4 feet outside my door (about 4-5 feet farther)
2370 down 2027 up
So the download speed is dropping like a rock, the upload speed is staying the same, but it's only 2k so hard to tell if it's being effected.
Thankfully I don't need to use it on my front doorstep a lot.
---------- Post added at 05:22 AM ---------- Previous post was at 05:09 AM ----------
Only other device i have to test same spots with is an iPod touch.
Next to router:
8418 down 2009up
near side next room:
8188 down 1995 up
Far side next room:
8150 down 2010 up
Outside:
5324 down 1986 up
So my old iPod touch has better wifi range.

I agree. My speeds were snappy quick (without bt) before this update. Now response times are slower. Asus is going in the wrong direction.
My speed is also down (per speedtest)but my range has been extended(per wifi anlr)and signal stronger. I dont get it I have the lowest Speedtest results since I got it in Dec.
Edit: Started uninstalling apps from the most recent DLs while doing Speedtests ..... and BINGO..... Got rid of Chrome and got all my speed back plus some... I dont get it but whatever Prime now working better than ever.

i was getting bad speeds after the update too, and random reboots, before the update everything was great. I did a factory reset and my wifi is great again and no more random reboots!
So how far is everyone away from there router? I only say that because the speeds are fine next to the router but from 10 to 15 feet they are horrible. I kinda wish I could downgrade to .11.1....
I give up. I've tried everything to get my TFP to get better wifi speeds from a distance and I haven't found anything that helps. I completely reconfigured my router, factory reset my device, uninstalled every single app I've downloaded and still whenever I get over 20 feet away from my router, my wifi speed drops below 2 mbps.
I'm starting to think the people without this issue have some crazy long range routers or something. I really love this tablet but I'm losing hope fast. ICS + tegra 3 is amazing, so I hope if I do return this there will be another similarly specced Tablet out soon. I can't go to ios.

How's that? Why not N routers set to B/G? No, there's more to it than routers; Prime's the odd man out on being able to reach my street. Channels 1-11, Mixed, B, G, N, etc... It's always out of signal before the rest.

Throughout house. What kind of distance from router. I get a good thirty or so feet with the Prime while maintaining decent quality connection in regards to through-put; my phone get's about fourty-five, laptops about the same.

Try setting your router to G band only and a low frequency like channel1,2 or 3 and check range with wifi analyser.... if its not better its not gonna get better

No Primes get same range as other Wi-Fi devices I've tested 3 Primes now on several different routers dead spot comes about 10 ft before other Wi-Fi devices.... it's the aluminum backplate that's the culprit.
I've done a few tests with the speedtest app and compared it to my droid x and my macbook. Overall it is slightly better than my droid in dl speeds, but isn't even close to my macbook. Is this normal or should my prime get closer speeds to the laptop? Thanks for any help.

Without exception, all serial numbers have the exact same problems. You don't have to worry about having the problem, because, if you have a TFP, you have the problem.

Usually laptops/desktops have much better wireless hardware and bigger antennas, so comparing it to a laptop doesn't make much sense.
To see whether you have a broken one just test your Wifi, if you are happy with it, you got a good one, if you don't like it it's broken
I'm slightly confused on this wifi issue that plagues this device, is it that the wifi can't be picked up from distances? (Short range) or is it that wifi is slow?
My wifi picks up fine, but I get less than 5 mbps average, when on my mytouch slide 4g I get over 12 easily..

This isn't true at all. It is pretty well documented that some Prime's are more affected by WiFi problems than others.
In general if your WiFi is as fast as your Android phone (give its a fairly recent phone) and you can step away from your WiFi source by a fair distance then your WiFi is fine.
In general PCs will process data from a WiFi signal faster than a mobile device, so it isn't unusual for WiFi to appear faster on your laptop than on your tablet.

Agreed. My Prime performs just as well as my Samsung phone and I still haven't had a single place out and about in was unable to connect when I should be able to. My Prime can max out my throughput from my router from across the house through walls/doors just as much macbook pro can though the signal is weaker, strength is same on phone and Prime. This is with a unit I got in December too.
Hello everyone. Fortunately I was able have both a BC0KAS and C3 Transformer Prime at the same time. I decided to keep one and receive a refund on the other. Naturally, I wanted to keep the better one and I was also sure that the C3 would be better considering all the stories I had heard. To be sure I proceeded to test the devices to see if there were any glaring differences. During the testing I decided to use my Galaxy Nexus as a sort of baseline between the 2 devices.
Background:
BC0KAS - Bought from B&H around January. It was unable to recognize its Serial Number and also had a white dot on screen as well as bad GPS (only tested in Google Maps). Sent in to RMA and received back after a long time. According to the RMA sheet it seems the screen was fixed and the SN problem corrected. There was no reference to a change in the GPS. Currently, it is on the .21 firmware and not rooted
C3 - Bought from Amazon in March. Currently, it is on the .21 firmware and is rooted. The only files that has been changed are GPS config files
Galaxy Nexus (Toro) - Purchased on release day at Verizon. The signal and performance of the device has been nothing short of stellar. Device is rooted with AOKP Build 29 (based on Android 4.0.4) installed,
Linksys WRT310N V1 – This is the router used. One set of tests was performed on the stock firmware and one set using dd-wrt firmware.
The internet connection is through Suddenlink. We are provided the fastest internet connection available for residential.
Test Setup and Methodology:
Both Transformer Primes were setup on balanced mode. The Galaxy Nexus was put into airplane mode and then the Wifi was turned on.
To test Wifi reception I have used a combination of Wifi Analyzer for a visual reference and the Speedtest app for a numerical reference. I used both of these applications and tested at various locations within my home to test the strength and performance of the Wifi.
When performing Wifi testing I was careful to test multiple times and to also vary the order in which the devices were tested in order to obtain quantifiable results that are not skewed by transients in the network speed. In addition, I would also alternate the location of the Transformer Primes (ie. test one prime lying to the left of another, switch locations and test the other Prime.) This may seem a bit redundant considering the nominal change in distance from the router is negligible, but we will see later that this actually made a substantial difference in the performance at one location.
In addition, I tested on one day using the stock firmware on my Linksys router. On another day I tested using dd-wrt firmware.
Results
Well the results are very surprising to say the least. Here are a few graphs.

"lightbox_next": "Next",

}
The Primes actually posted better results that the Nexus.
NOTE: The first tests of the BC0KAS Prime were left out because they were performed on a different server.
We see a lot of degradation of the speed, but the Nexus holds strong. Notice also the the C3 is consistently the lowest
Now the speeds are getting very low. I want to note that this signal must pass through many walls in addition to the distance. Also, when initially testing at this position the C3 lost the network. I had to walk closer to find it then proceed again.
Okay, so I decided to test after I installed the new firmware on my Linksys (NRF = New router Firmware).
Since some have asked, I will give a little more information on this. The firmware I am using is provided by dd-wrt. This is an open source firmware that allows you to do more with your router then I will ever understand. If you are curious if your router is compatible just google search "Manufacturer" "Model Number" dd-wrt. Generally you will find the dd-wrt wiki page for your router if it is supported.
NOTE: Changing your router firmware is just like rooting/ROMing. There are a lot of risks you have to accept when doing this and you should proceed with caution! Before attempting please read and re-read your instructions.
As far as settings I didn't change them too far from the original settings came on my dd-wrt. I did use Wifi Analyzer to select the channel with the least interference in my area. Also, I noticed that my TX power is set to 71mW where as I recall reading that the older Linksys WRT54G may be set to 25mW originally. I can say that both my primes now show FULL bars while close to the router. Used to they may still only show 3 bars when separated by 4ft and 1 wall.
I want to stress again to perform this with EXTREME caution. The developer community for router support is not large anymore. Most information I read was dated pre-2010. This means that if something goes wrong, you may not have many people who are available to help.
Now for the results:
In this instance the BC0KAS was having a little difficulty keeping up with the C3. The more important point here is that the wifi speed is much greater for both devices!
Notice the BC0KAS dropped below the C3 at the beginning of this test as wll. This was caused by the slight position change I noted earlier. I repeated the test several times and continually found that the tablet positioned to the left saw decreased throughput after those tests I picked up and help each tablet while performing the test.
And one more of all the test together to give you an idea of the total picture.
Here is another graph I found interesting. This graph doesn't perfectly overlay each test with each device but it gets the point across. In most of the tests the upload speed held at a near steady 2200kbps. This happened before and after the router firmware change. Even when the upload speed did drop it was normally not near the rate that the download speed dropped. Actually, at times the upload speeds were faster than the download speeds. I will update the graph tomorrow to better convey it.
Conclusions
There a few definitive things I feel I can note from this experiment.
1. My C3 Prime experiences more signal degradation than my BC0KAS Prime
2. Not all C3's are perfect and on the contrary, not all BC0KAS are bad
3. The new router firmware increased throughput drastically
Really, I feel that is all that you can realistically say. I am excited that my wifi is so drastically improved with the router change. I am also happy with my BC0KAS and of course I plan to keep it now.
Let me know if you have anything else you would like for me to test, or anything I should change about the test.
-MK
yeah its about the same for my C1 if i compare it to my DesireHD. There are some spots far away from the router where my DHD has better throughput, but not consistantly. If I'm far away from the router the throughput is very inconsistent on both devices. I guess thats what happens with all radio signals, its basically the same on FM radios.. Anyway i'm happy with the signal because overall its pretty much the same on all my devices.
I have another problem with wifi though, see screenshot. And this is with wifi off when screen off!
My BC0KAS Tfp has acceptable WiFi performance. Even though the signal meter shows lower strength than other devices, actual speeds are the same as other devices. It is not until you get to the very end of the range, do you notice a drop off in performance. I know there have been some bad/ defective primes in consumer hands, but really not as bleak as the threads here would leave you to believe. It is still a kick butt tablet!

+1 for my BCOKAS, can't complain.
very interesting test. i did a similar test with my htc desire and BC0KAS prime to determine the best channel to set my router to. i sent you a PM about this, but was also wondering if you wouldn't mind sharing the router settings? while i can blame the prime all i want for having weak wifi, i want to make sure that my router is optimized first.
