I just finished doing some testing on the BT/Wifi issue for the prime. I also repeated the same testing with my EVO 3D and I am getting similar results. That transferring data over bluetooth is significantly affecting wifi. This is using the speedtest app and each test was repeated 4 times. Have others tried testing other devices?
Here are my results.

What application and file did you use for transferring over BT? I would like to test this with my OG, TFP, and MT4G. Because I have never noticed any degradation of WiFi on my OG TF, but only use Bluetooth for Tablet Talk (SMS bridge)

I used the "File Expert" file manager available for free on the marketplace. To transfer a file over bluetooth all I did this in File Expert.
1. find a directory with a video in it
2. tap-and-hold on video file
3. tap Send files
4. tap Send via bluetooth
5. The device will search for available bluetooth devices
6. Select the device you want to transfer to
7. Go to other device and accept the transfer.
Well, I'll be damned. I just ran the same test on my Samsung Epic 4G Touch as I've been running on my Primes:
1. Wifi performing normally.
2. Turn on Bluetooth. Wifi continues performing normally.
3. Pair with my Motorola S9-HD headphones. Wifi continues performing normally.
4. Start streaming music via Google Music to the headphones. Wifi drops SIGNIFICANTLY. No need to quantify, because it's such a dramatic drop (say from 8Mb/s to <1Mb/s here on my work network).
5. Stop streaming, wifi recovers.
I also went the additional route of playing the same music over the external speakers (headphones disconnected). Wifi performance remained roughly the same, allowing for the bandwidth taken up by the streaming (say, from 8Mb/s to 7.5Mb/s).
I'll say that the phone didn't completely drop Internet connectivity like the Primes do, but wifi performance absolutely dropped through the floor. Maybe the Primes are just a tad bit worse than some other devices, like they are in wifi performance in general, but not the nightmare scenario otherwise implied.
So i ran the test and its funny becuase im running the exact same test.
With the evo 3d and also with the motorola s9 HD. i was hoping if someone else can run these kinds of test on a SSGS2 or some other HTC device or even an apple device.
I have a sub-sub-par LG Optimus T and I have already tried to replicate this issue on it. I pair w/ my BT Philips headset and stream Pandora w/ no lags. Speeds are consistently the same.
My Prime, on the other hand, will droop instantly and intermittently disconnect as soon as it is paired to the same BT headset on the same WiFi network.
Cheaper parts = better wireless performance? I think not... I hope not.
I've seen it before. no matter whether using a phone or tablet, BT will affect wifi signal to some extent. some more then others. there's no way that they couldn't because they are both on same wireless signal 802.11 or whatever it is. depending on phone or tablet and strength of signal, some will be affected more than others or maybe even some not at all.
some been mentioned this before but no one here seemed to listen..lmso

While it is true that PANs and WANs use the same protocols and there could very well be some wireless conflict, not only do I not see it on a much more inferior device (my phone), but the WiFi decline on my Prime is quite awful.
We're talking speed declines of 80% or more and random disconnections within minutes.
Both wifi 802.11 and Bluetooth use the 2.4 Ghz spectrum.
One nice test will be if someone could try duplicating the test with the Transformer Prime using the 5 Ghz 802.11n spectrum (does the TP have capability for 5 Ghz?)
I'm not home right now so I can't test it at the moment, but I will say this:
On my Galaxy Nexus, when paired to a Bluetooth speaker and on my WiFi, the audio gets incredibly choppy when I try to use my phone. As a result, I've been disabling WiFi and using my 3G connection when paired to my Bluetooth speakers, which is better. This sounds like the same issue. I'll specifically test speeds on my Galaxy Nexus when paired tonight, but I'm also suspecting this issue isn't limited to the Prime.
The problem is that ASUS has f***ed up so damn much with this product already, that everyone (including myself) is ready to pin every little thing on them and their incompetence
FWIW, I have no problem using wifi while streaming BT audio on my nexus S. I can even turn on my microwave and though it'll cut out momentarily sometimes, it recovers. I can even put it IN the microwave (not turned on) and it still mostly works (stuttery).
I can't stream on my prime, even with the microwave off

Sadly, the Prime does not support 5GHz connections which surprises the hell out of me. Although the aluminum would likely kill it anyhow. I suppose this means the TF700T won't support 5GHz either, come to think of it.

This.
There will always be some sort of interference when using them at the same time - the issue here is that in this case it is enough to notice it.
Even my Bluetooth Logitech mouse was interfering with my laptop WiFi before I ditched it for one of the proprietary wireless mice.
Well, I have a hard time giving ASUS so much grief about this when my Samsung Epic 4G Touch has roughly the same performance. I tried browsing while streaming music to my BT headphones over wifi and was having a hard time getting any sites to respond. I turned off BT and played over the external speakers, and browsing recovered. Pretty much just like on the Primes I've tried.
So, yes, maybe the Prime is marginally worse than the Epic 4G Touch, but not so much so as to be an entirely different problem. I never noticed this on the phone because I usually only use my BT headphones when away from the house and on 3G.

I'm not one of the complainers, but this is a disappointing oversight. I know for a fact that the iPad2 I got for my sister can use the 5Ghz band 802.11n, and I suppose I assumed that all modern competitive tablets could too.
Both bt and wifi operate within the ISM (Industrial, Scientific and Medical) 2.4 GHz short-range radio frequency band. The close proximity of the rf sources is bound to cause interference, so just need to be aware of the quirks and limitations.

Oops, someone already beat me to it. Good job!
Well, I tested this out using my BT speakers and both my Galaxy Nexus and Transformer Prime. The TP is messed up. My Nexus streamed music and downloaded at about 10 Mbps, while the Prime crawled at about 0.25 Mbps while streaming. Do the problems ever end with this tablet? Does Asus actually employ real engineers? Unbelievable.

OP, your test only needs to show streaming with Wifi vs streaming with Wifi w/ paired BT device (i.e. stereo headphones/speakers)
and I don't see any results of streaming with Wifi in your post.
Has anybody ever thought that these Supremely Awesome Magnificent Super Powerful SoC's aren't so super awesomely powerful and get bogged down? I mean seriously, I don't expect much from these devices and bt has always been "just ok" technology. Of course I'm expecting flaming, b/c ppl actually believe these mediocre devices can multitask like a frickin quad core intel x86 proc.
Bluetooth and Wifi essentially operate in the same frequency band(s). As such bluetooth and wifi have always messed with each other. This is made worse by the fact that the phones mobile, low performance nature further limits the ability of the devices to handle multiple functions.
The "issue" people are reporting with the prime is a degradation of performance in excess of the norm. The key is whether or not the degradation is immediate and steady, or degenerative. With most devices you lost performance due to load on the device and RF interference, but the loss is steady and doesn't affect real world performance. For the primes with the issue there is the instant performance drop and it gets consistently worse until the connection becomes unusable and/or fails altogether.

TF101's Tegra 2 doesn't exhibit the same limitations. Though that doesn't necessarily mean the Tegra 3 doesn't have some bug.. but I sure hope not.
I recently sold my ipad1 since i wanted to get out of the apple ecosystem. For the last week I been researching which android tablet to get. At first I looked at the Galaxy Tab 10.1 which I liked spec-wise but when I went to BestBuy to take a look at it, I noticed it was laggy and stuttered just flipping between homescreens (which im not sure if all galaxys experience this or it was just the display screen not performing well) so i started looking for something more meaty performance-wise and led me to find the prime. However, theres been 2 things holding me off from buying it:1st is i just cant find it anywhere, and 2nd is when i found out of its wifi/bt problems. Im not planning on using any bt, so could I expect wifi to work flawlessly not using bt? (wifi is important for me).
The thing is that I need a tablet to read...i shouldnt have sold my ipad without having bought the android one...
some earlier units had the wifi/BT problem. seems to be an issue streaming audio to BT headset while streaming wifi connection to tablet. like on internet or watching a movie. some reported drop in speed. a major contributing factor is because the wifi & BT on same chip/component. its something with the BT audio interfering. we also have alot who report they can do both just fine w/o noticeable drop in speed. if you don't even plan to use BT in that way then you should be fine. even if you did, you should still be fine.
I've had my Prime since 12/22 and wireless performance has been great for me. never drops a signal and consistently gets the fastest download/upload speeds. just search for an online retailer carrying the prime like best buy or something. they are out there but always sell out so quickly. This is the best and most powerful tablet Android has at the moment. its well worth getting. Very sexy looking tablet also
just check out the link in my signature, Positive Transformer thread, to put some balance to things. there's always a flip side and not as bad as it may seem at times.
Well,
To be honest, I like my prime a bunch but if I'm on wifi, I cant connect my PS3 sixaxis through bluetooth. I have to kill wifi then connect the controller. I havent tried reconnecting the wifi but I know I cant use bluetooth if wifi is already active just from that.

I don't have this problem myself and use my sixaxis a lot. If you aren't using bluetooth anyways then no worries there. My wifi is just as powerful as my Samsung phone.
Been looking around to see if there is a consistently good performing wifi router and prime combo. Since we ain't getting any love on the primes wifi side I figure maybe a different router will do the trick
I currently have a e4200 which performs in the 3 to 10 mbps / -55db range in my apartment which at most I'm 7m from the router. Ideally I'd want something that can do a min of 15mbps constant. Anyone have a good experience with a particular router?
PS. I tried multiple firmwares and settings on the e4200 and disabled MLS or whatever. Still prefer something faster so my HD vids stream properly
Im using a Netgear WNDR4500 and streaming using BSplayer to play 720 and 1080p vids from my linux server ....and never have had any issues

I am actually using the New Asus RT-N66U (Dark Knight) with no problems. But, what is your ISP speed? There is a guide. I am to lazy to find atm. But it talks about changing a few settings... (channel etc) to get better performance.

I have the Cisco e4200 wireless N and it works fine.
I'm streaming from my local NAS so ISP speed shouldn't matter.
I've tried a lot of different channels but one of my main issues is that my air is flooded with neighboring wifis so most channels are bad
I've heard good things about the Asus one, might check that out.
btw my e4200 works...its just not as fast as I need
My old as dirt Linksys WRT54G works fine with my Prime. I did do a channel scan to find the channel least used by the many other WiFi devices in my area.

In case this hasn't been suggested before, this printable antenna dish may help draw in better reception from the fringe. Only experimentation will tell as everyone's situation is different. Years ago, my own use of this dish did help me pull in distant signal and keep a stable connection.
Keep in mind, some wireless access points with dual antennas have one that both transmits & receives while the second antenna receives only. Concentrating the signal with the reflector dish on the main tx/rx antenna will affect its reception for all your WiFi devices. Same thing if you only have one antenna.

To get past the attenuation caused by the all aluminum panel, probably one that will result in sterility
Seriously though, a router OE seller should use the Prime as a litmus test for how good their router is with signal. Not in the same room of course, but at least one floor of seperation and an average expected range. Hard to believe the Acer A500 is actually weaker for wifi than the Prime.
Am so close to pre-ordering a Z3 Compact tablet, and will pay the premium if the Remote Play will really work as advertised.
All we have to go on are some youtube vids of the remote play feature on the Z3 and experience by the public on the Vita.
What I want to do is sit in front of the TV (watching Eastenders or something else as dull ) and at the same time game (mostly FIFA15)on the Z3 tablet while on the couch.
Will it really be free of enough lag to allow me to twist and turn and pass the ball and shoot with delays that I wont notice ? I really hope so. My worry is that if it does lag a little, then as poor as I am at FIFA15 already, I will only get worse to the point that I wont want to use remote play feature and therefore make my expensive tablet as useful as a tablet at half the price ( I will use it for surfing and tv shows on top of remote play).
Your comments, thoughts and experiences with the Vita would be much appreciated.
I got my new z3 tablet yesterday and immediately used remote play because this feature is the main reason I bought this Tab.
Unfortunately I am underwhelmed by the performance.
My Ps4 is wired hooked up to a Easybox 803 (from Vodafone). The Z3 Tablet is connected via WiFi of course.
It doesn't matter if I play Destiny, Resogun or Games like Fez. The Gameplay is smooth but every 30 sec or 1 min I experience a freeze for 2-3 seconds or the picture stuttered or something equal... Very annoying.
I tried to put the Ps4 in the DMZ of the Easybox but same result. WiFi Connection on my home WiFi is at 144mb/sec, n only and 2,4 GHz, don't know if that is enough or not to remote play smoothly.
Any idea on how I can improve my gaming experience?

I read that 5ghz is better from the router. Havent tested it myself however.
i heard that also. People think that a 2,4 GHz WiFi plus the Dualshock 4 (also 2,4 GHz) is the reason for the Problem...
So I tried using only the on-screen buttons and disable Bluetooth in the Tablet.
At least for me same results as with Bluetooth....

I hope I'm posting this in the right sub-forum, since I think this is not a device-specific problem.
So, I recently bought a Parrot AR.Drone 2.0 and as you probably know, the Drone can be controlled via an Android App (https://play.google.com/store/apps/details?id=com.parrot.freeflight). First I simply tried the app with the default touch controls, but it was not precise enough and I missed the tactile feedback. Then I had the idea of connecting my PS3 controller with the Sixaxis app (https://play.google.com/store/apps/details?id=com.dancingpixelstudios.sixaxiscontroller) to my phone (Moto G 2nd Gen., 2014, Dual SIM variant) and controlling the Drone with that. And here comes my problem:
If I have only Wifi enabled on my phone I can fly about 25-30m with the Drone
If I enable Bluetooth (to use the PS3 controller) and Wifi the distance drops to about 10m and I get a lot of connectivity issues to the drone.
I also tried my ASUS Transformer Prime (TF201), that's even worse. As soon as I turn on Bluetooth the Wifi signal drops to almost nothing.
I have found others with similar problems (for example: http://android.stackexchange.com/qu...wifi-reception-severely-affected-by-bluetooth or here: http://forums.androidcentral.com/sa...-samsung-galaxy-tab-s-10-5-wifi-problems.html).
Can anybody explain why the Wifi quality drops (massively) when Bluetooth is turned on?
I was experimenting a little more this weekend and the issue is definitely there. I was outside of the city, where there was no other Wifi or anything. Looked at the networks with Wifi Analyzer before and after turning Bluetooth on. Without BT all channels had max. rating, with BT on they all dropped to 1-2 stars...
