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.
My Samsung gs2 has this and most of my devices also. I was surprised to see prime doesn't.

"N" capability is not a description of which wireless band a chipset can use.
Short answer: No
5Ghz wireless tends to have a shorter range than 2.4Ghz anyway and most people seem to be having issues when far away - so they'd probably be switching to 2.4Ghz at this stage anyway...
The main benefit of 5Ghz over 2.4Ghz is that 5Ghz has much less interference from blutooth, microwaves, DEC phones, other wireless networks and so on. If the problem was purely 2.4Ghz then you'd have problems with other devices as well.
Pogo Stick Mechanical Contacts are Signal Killers.
If the maker cuts cost by using materials that easily tarnish or oxidize, you can be sure that signal will face an untimely death. It's just like your flashlight that needs to be shaken to revive the battery contacts. So it doesn't matter what freq band you use, other factors are in play here.
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.
Hi Guy's,
Does anyone have any idea how to improve the wifi strength?
I am using a BT homehub 3 wireless N router and all of my other devices (laptops, iPod Touch, ZTE Blade etc) are able to pick up wifi ins ome areas of my flat and my viewpad will show no signal. My router broadcasts all of the wireless type at the same time and I have tried only broadcasting wireless g.
Are there any tweeks that can be made or is it just an underpowered chip that cant talk back to the router?
My first post, please be kind.
I'm a little frustrated with remote play on this tablet. It works great for a minute or so, then it will stutter heavily and lose signal a bit for 5 seconds before it starts working again for a minute until it starts stuttering for 5 seconds and so on.
Is anyone else experiencing this? My ps4 is wired directly to the router, (AC68U) and I've tried a spare router I have which does the same thing.
No amount of tweaking router settings /channels seems to help, I'm stuck!
Thats unfortunate, I've had great success on both my devices, i have the Z2 Tablet and Z3 Phone. I'm able to play Destiny Level 27 Nightfall strikes and 28 Story modes no problem (i do have the very slightest input lag but its not really anything to effect game play, u get used to it after the first couple minutes)
I plug into my router and use wifi from my device. I have my network on wireless AC using a AC1900-Nighthawk Smart WiFi Router. Anyway it seems alot of people are having issues so i guess im lucky, i F**kin love it!!
I managed to sort the problem. Turns out that disabling location in quick settings solves the lagging.
Bad, big lags and disconnections. I've ps4 wire connected to my router (TP LINK TD-W8970) and wi-fi connection with Z3 tablet.
I'm in the same room as my router but connection is poor. I'm getting disconnects every one or two minutes, artifacts on the screen. Lag is also noticeable, so aiming works with big inertia. BTW I've only tested this with Destiny.
I've bought Z3 mainly due remote play feature, I could wait for new nexus, but remote play was big feature for me.
Now it looks like something not usable, at least in high action games.
It's ok. Better than on the Vita, but mainly due to being able to use a DS4. On my home wifi (wired PS4, Meraki MR18 dual-band 2-stream 802.11n wifi AP) connection is flawless, as it should be.
My only bugbear is that it won't allow a connection over 4G/LTE. I've got 20Gb Data I can implement and if I'm connected to 4G it's likely to be faster than most public wifi points, so why can't I use it?
I was going to say I literally got an ac68u and z3tc the same day and it works flawlessly. Given I have 150mbit home Internet and dual 2.4 and 5ghz and z3tc was on the 5ghz band while 4 other devices were connected two watching a movie remote play was working fine. I'm glad you fixed it!

What Wifi settings do you have on your AC68U? I've got the same router & have lag issues with remote play when connected to the 5ghz band (2.4ghz is even worse). I've tried every combination on the wifi settings page but nothing can keep a stable AC speed connection.
When I first connect it connects at 866Mbps, then drops down to 300Mbps or lower in less than a minute, has anyone else experienced this?
I would also want to know ac68u wifi configuration for flawless remote connection. I was going to buy xDSL capable model (Asus DSL-N66U) hopping that 5 GHz wifi is the solution for my lags in remote play.
Tried to play GTA V. Very dissapointing expirience: lags, artefacts and disconnection in one minute (did not try after that). Location was off. I beleive this relies on the good wifi router very much.
Mine Works good after a few tweaks, one of the big ones is on the PS4, select the option to connect directly to the ps4. I havent had a problem since then. I wish they would unlock it to connect over different networks. I had the vita i was a couple states over visiting family and i could still play the PS4.
I agree with the majority of comments on this post. The gameplay is very laggy! I tried to play fifa 15 on it and i eventually gave up, movement is slow and pressing a command on the controller takes like a half second delay which makes the game really frustrating. I hoped it was quicker. Not sure how they'll fix this though, i have a fibre optic connection too so it's defo not my internet. Think there's just a few issues that need addressing
I would like to buy these device but for me is very important that the remote play works ok
I have a z3 compact and works very well.
I need more comments of remote play experience please
If the tablet tether to ps4 without enabling data. (ps4 connecting to z3 tablet 's tethering without enabling data), would it work? Would this make the experience better?

sorry I was on vacation!
I spent about an half an hour when I got my router when I got it but I manually set my 2.4 ghz channel so I get zero interference and max range. I also manually set 40hz to get 100mbits on 2.4 which blows the 1900 "nighthawk" out of the water when I had it. Then I set up 5ghz with minimal differences to default settings as nobody else had a 5ghz network around. I feel like encryption type has an effect on remote play but I need to check. I reccomend opening your network, using the 5ghz channel then remote playing. Again I get zero issues with remote play and was also able to play a few rounds of injustice over 7400 miles away. I love the ac68u allot more then the nighthawk (cnet also reflects this conclusion) For 2.4ghz long range speed, it's reliability and stability.
Since PS4 2.5 fw it is possible to remote play 60 fps. Problem is Xperia Z3 tablet is underperforming. Xperia Z3 phone has a solid performance on high settings almost PS Vita level, no problem here. In spite of sharing same specs the remote play experince on tablet is just meh on high settings. Phone and tablet settings are all the same connected to 5GHz wifi, both has Lollipop 5.0.2 up to date. Phone is D6603 tablet is SGP611.
I see 3 options that could cause this:
Screen size 5,2 vs 8;
App apk differences, phone vs tablet;
Faulty tablet hardware.
Synthetic benchmarks show very close results when comparing phone and tablet performance.
Why is the tablet underperforming in remote play?

I tried this yesterday and the recurring lag issue completely disappeared! Absolutely perfect now, thanks.
DS4 Interference
I had a lot of problems with remote play, but now i sloved all!!
The problem was interference with DS4 and 2.4 ghz WiFi!
Switched to 5 Ghz wi-fi and all work great! Also with the last upgrade with increased fps on remote play!!
Remote Play is a hit or miss I was having problems streaming before I tweaked my router 5ghz ports and band now I can stream 2 rooms away from the router perfectly
but there is a lot of variables like router brands , 2.4ghz vs 5ghz ac no ac how far from the router and how many walls in between how much interference in case of living on apartment neighbors wifi interference so yeah
I have been taking experiments recently and found out that reverting back to Kit Kat on tablet (23.0.1.A.0.167) is a better remote play experience than on Lollipop but still not that good as on Xperia Z3 Phone (LP 5.0.2), very close though.
Worth mentioning that Sony applied a bandwidth cap at 10 Mbit/s both remote play and share play. Which is interesting because my network setup link speed is 433-866 Mbit/s and real life scenario like file transfering is ~140 Mbit/s. So local network LAN remote play shouldn't be capped at 10 Mbit/s.
I still don't understand why the Xperia Z3 Phone can do better than Xperia Z3 Tablet in same environment, same settings, same hardware, etc.
Yesterday I turned off 2.4 GHz radio in router and felt that controls were more responsive maybe latency got better. In fps multiplayer games I definitely felt aiming and controlling were better. I cannot prove it with measurements it is only my sense but if you have a dual band router you can try to disable 2.4 GHz band and see if remote play is faster.
