I've gotten in touch with someone at ASUS. He is working with me to see if he can reproduce the issue. Once they can they can try to fix it. Anyone who is having this problem and those who aren't please list the specifics of your device.

Color/Capacity

Serial Number - Or at least part of it. I don't see a security issue with giving the whole serial, but maybe there is.

ROM Version

Router Model

BT Device Type and Model

Conditions of testing. Example. I stream video via Netflix and/or Subsonic streams of video from my fileserver. The latter seems to kill the connection faster than Netflix. Also if anyone finds a faster way to kill the connection that would help too. I need to increase the chances that I can get ASUS to recreate the problem.
[Asus  Eee Pad Transformer Prime] the_game_master:
While i didn't see this problem at first watching a non HD video stream through YouTube, i got an excessive amount of buffering from HD vids, and this problem is definitely apparent via Netflix.

I had to turn off my Bluetooth headphone for the Netflix stream to continue because the playback degraded to a halt. I wonder how much poor wifi reception from the aluminum backplate is factoring into this issue.

OT: I saw more WWE content up on Netflix here on the Prime than i recall seeing on Netflix through Xbox live. :eek:
[Asus  Eee Pad Transformer Prime] skorp_jon:
I have cancel my order at amazon. I will wait couple of weeks if these problem will be fixed and then order it again. Or i will order some other tablet.

Wifi tether to SGS2 (E4GT)

Apple Bt Keyboard (Class B) works fine typing now

Apple BT Keyboard + Logitech Android 3.1+ mouse VX 470 + wifi on - disconnects within 2 min. Bars drops from 3/4 to 0/1 (-0/-1 dB)

Complete disconnect. Have to turn BT off, disconnect all devices, turn wifi off, then wifi on to reconnect. Sometimes even soft reset to reconnect

---------- Post added at 05:11 PM ---------- Previous post was at 05:08 PM ----------

Oh, in addition, I just tried this now.

Just use Logitech VX 470 BT mouse. I started up Netflix, turned on BT, turned on mouse, signal immediately cut from 4----> 1bar (I'm 8 feet away from router, mouse in maybe 24 inches from prime)

After 1 minute Netflix cannot start up stream, "server disconnect please try again"
[Asus  Eee Pad Transformer Prime] setite:
Thanks. I submitted the information to the guy I'm in touch with at ASUS. I'm sure it will help them lock down the problem since your case seems to be faster acting than mine. I wonder why my problem is the same, but my bars are never affected. My prime always acts like it has a full connection.
[Asus  Eee Pad Transformer Prime] cbyankees3:
Has anyone played onlive with the Bluetooth controller yet. Is it playable?
[Asus  Eee Pad Transformer Prime] jfortier777:
I've noticed rather disturbingly that when I retest this in other locations the loss of connectivity has maintained a very consistent ratio.

On the order of ~1/10th of the available bandwidth.

Could just be a coincidence but most of the tests reflect it.

If it isnt just a coincidence...wtf would it mean?!

...consistent repeating pattern of packet loss or something of the like?

...bum components?

A hint at something deeper
[Asus  Eee Pad Transformer Prime] setite:
Well first it explains why my tablet still stays connected at home but dies altogether when tethered to my phone. It is not a coincidence and if I understood the tech that detail alone probably hints at the problem almost perfectly. I suspect perhaps there is some interference of the physical electrical kind as opposed to pure RF issues. Maybe a short of some sort in some units that causes excessive interference when both pathways are being used. I'm hoping it's not something physical but I fear they might have to recall these tablets if it's a mechanical/electrical problem. I wonder if this is tied to the wifi issue that was reported by some reviewers. Perhaps they slapped together a fix for wifi that in turn broke wifi/bt co-existence.
[Asus  Eee Pad Transformer Prime] jordy5:
Isn't this all just the downside of having Bleutooth v3? I thought (I'm not a full expert) that in Bluetooth V3, it essentially piggybacks on Wi-Fi frequencies. By this it is likely that when you start tranfering data over Bluetooth it will reduce the Wifi speed.

Maybe if someone knows which channels or frequencies Bleutooth uses, you can change your wifi to a different channel? Again I'm not an expert :)
[Asus  Eee Pad Transformer Prime] Sokonomi:
Hey just an idea, doesn't the wifi tester app basically have a spectrum analyzer?

See if you can pick up a particular spike change with BT on/off.

It should expose on exactly what channel BT is billowing out a heap of noise,

allowing you to pick a clean channel and thereby avoiding BT.
[Asus  Eee Pad Transformer Prime] the_game_master:
Netflix playback quality is greatly degraded with Bluetooth headphones paired.

I have no problem with this on XPS M1210 laptop, so there's definitely a problem with the Prime.

---------- Post added at 06:01 AM ---------- Previous post was at 05:59 AM ----------

despite showing full Wifi bars. With up down arrows
[Asus  Eee Pad Transformer Prime] setite:
Hmm. Didn't know that the prime had BT 3.0. To be honest I hadn't checked the specs on the ATP as I assumed they met or exceeded the OG Transformer. My googling shows the ATP as having the regular BT 2.1.

Either way this is not a problem I've had in literally dozens of other bluetooth devices I've had. I've been dealing with bluetooth for around a decade and at this point I just expect it to work, let alone work well.

The_Game_Master my problem is like yours. No changes in the signal via the bars or testing apps. The wifi just slows to **** or till failure. I can't find an app that scans properly to see what bluetooth is doing on an RF level. I really don't think a problem this big is related to actual radio waves. I would expect the problem to be more electronic. I am going to be monitoring this issue and my return window. Due to the holidays it looks like the return deadline via Amazon is Feb 4th.
[Asus  Eee Pad Transformer Prime] jordy5:
Alright, so your trying to compare laptop components to Mobile components? The Prime has a mobile chipset and has components which are probably as condenced as possible as it should fit normally in a much smaller space. Your laptop has a Mobile WLAN PCI-mini card in it as it is most of the times an optional components in laptops, a seperate (maybe v2) Bleutooth.

I rather see someone comparing a Samsung Galaxy S/S2 or another android phone and combine streaming and wifi statistics.

<EDIT> I do see that the Prime supports Bluetooth 2.1 + EDR. Don't know if bandwidth sharing is also for the chipset in the PRIME. I have no streaming equipment to test with other devices, but I can remember I had issues with Wifi + Bleutooth also on my Galaxy S. Can't remeber having it with my S2</EDIT>
[Asus  Eee Pad Transformer Prime] the_game_master:
I don't have any other tablets or smartphones, therefore I can only base my comparison off other devices I've used the same features and functions and had no problem from.

Why should there be an exception in place because one device is a tablet the other is a notebook?
[Asus  Eee Pad Transformer Prime] setite:
A laptop has some components which are bigger. I was gonna try and refute your statement but the pictures AzureWave AW-NH615 is a part I can't seem to track down technical specs on. So I have no idea if that particular component exists in any laptopls but I'm willing to be that it does as I don't see a reason why there would be all that much variation in Wifi / BT chipsets.

I suspect the part is related to the AW-NH611. But I've also read that the ATP uses broadcom for the wifi, while that AzureWave chip has the trifecta. wifi/bluetooth/FM. Bluetooth chips are probably comparable if not the exact same in most mobile devices including laptops. There might be differences but they still have similar components and as I've said in other posts. These things all work in every other device. This clusterfrak is unique to Asus and the Prime.
[Asus  Eee Pad Transformer Prime] TerrorTedd:
Do you guys think this could be fixed by some update? Or is this yet another design flaw?
[Asus  Eee Pad Transformer Prime] setite:
It's not for sure yet. I think it's a design flaw. ICS comes out on the 12th so we should know then. If the ICS ROM doesn't fix this then nothing will.

BT and WiFi are both 802.11 spec so they share the same airwaves for the most part. As I understand it BT automatically hops around to find the best channel.

I have a Samsung Galaxy Nexus, Asus Transformer and Asus Transformer Prime. Give me a test and I will do it.

EDIT: At the end of the day there should be differences in benchmarks between a phone, tablet, netbook and notebook. But there shouldn't be show stopping real world differences.
[Asus  Eee Pad Transformer Prime] nyijedi:
For what it's worth, when I use BT to tether my Galaxy Nexus to BT speakers, the audio gets very choppy as soon as I start using my WiFi connection. I never really looked into it any further, but this thread reminded me of that. Maybe it is related to BT 3.0.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Yours may be an individual problem. There's probably ten times more GN in the wild than Prime's. Has anyone on the GN forum reported an issue? If it was common I'd imagine they would as BT is a lot more heavily used on a phone than a tablet. The SGS2 and G-Tab are both 3.0 and have no issues with using BT & Wi-Fi concurrently.
[Asus  Eee Pad Transformer Prime] nyijedi:
I have a GSM Galaxy Nexus, my buddy also has a GSM Galaxy Nexus, and my wife has a Verizon Galaxy Nexus. I'll test them all out when I get a chance and report back.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Don't try them on whatever config yours is having issues on. If it’s your environment that's the issue they should all perform similarly. You might want to try yours connecting to a different AP. Do you have a D-Link router? Samsung devices are known to have a distaste for them.
[Asus  Eee Pad Transformer Prime] nyijedi:
Actually, I do have a D-Link router. I didn't know about that. I'll see what else I can do testing wise.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
If you're in the market for a new router, the NetGear N900 is kick-ass. Samsung devices have always done well with NetGear kit.
[Asus  Eee Pad Transformer Prime] Blairware:
Stop forcing issues. You are part of the PROBLEM, not the solution(s)

You need to go find a 12 step support group for whiners. You don't look for workarounds or solutions, you look to break what you can and then cry about it. I am all for testing the limits of a feature, but it's not about

breaking it

, it's about

finding the best way to make it work.

.

I and others are weary of your bellyaching. I tested performance of Bluetooth and Wifi, and did in fact see a drop under certain conditions. However, I also did a completely wild and unscientific test: I played streaming video, with streaming Bluetooth audio, and had a mouse attached during the test. ALL of the features worked better than acceptably, they worked WELL. In fact, I have absolutely NO ISSUES, other than a brief buffering I saw at the very start of the video stream for perhaps 5 seconds. There was no recurrence of this, and all three signals continued to work for over 90 minutes of testing.

Now I could be like you and find conditions where it doesn't work, or where the signal is too weak to perform acceptably, but to what end? To "warn" people not to buy the Prime? How is that in any way helpful? This is a developer forum where people come

looking for solutions

, not a ***** and moan session where people come to commiserate on their misfortune in buying a device. If you can't help yourself, and all you do is try and prove how ****ty the Prime is you are part of the PROBLEM not the solution.

I am not blind, and trying to "convince myself" these problems don't exist. I am actually very disappointed. I saved a copy of CoPilot to install on the Prime, after using it on my OG Transformers (plural). Looks like that's not going to work. One thing I have been trying to find out, unsuccessfully so far, is if there are degrees or variation on GPS performance from unit to unit. I actually hope NOT, cause I can see myself endlessly exchanging these, trying to find the best of the bunch, LOL.
[Asus  Eee Pad Transformer Prime] dorob002:
I couldn't believe all the problems I was having with Google Music and my BT speakers. I was very disappointed to find this thread. I'm having all the same issues with WiFi dropping strength when the tablet is connected to BT speakers.

Frankly, I know very little about the technology, but I've noticed that my problem has nothing to do with BT being turned on or off. I always have it on, and the problem occurs only when the tablet is actually connected to the BT speakers. But if BT is in essence "off" when not connected to a device, then clearly this statement is irrelevant.

I also don't buy all this talk about WiFi and BT interference. Sure, they can interfere. But this can't be the problem we're all having because tons of other devices work just fine when trying to do the same thing. In fact, this is the first device I've had a problem with in my home. I have gotten awesome performance streaming music from the web from a variety of devices (Fascinate, Atrix, Charge, iPhone4, iPhone4s, iPad2). So, it can't be a general WiFi/BT problem. There is definitely something up with the Prime.

I REALLY hope this can and will get fixed ASAP. I don't think I can justify this inconvenience.
[Asus  Eee Pad Transformer Prime] demandarin:
once again this is not an issue affecting everyone. after seeing several comments on how the BT and wifi on together conflicts with speeds or whatever, i decided tl test it out. well I just ran speedtest.net 6 times. 3 with just wifi on and 3 with BT on also. throughout all 6 tests the speeds stayed consistently high. even an occasion where both was on and I pulled faster speeds.

I haven't really read through this thread but I thought I saw someone mention the problems only occur under certain situations. what are they? cuz from what I'm seeing there is no issue with mines. I don't have a BT headset or anything to test. only my Atrix 4g.
[Asus  Eee Pad Transformer Prime] techjunkie9194:
This could have mentioned somewhere and I have missed it, however, my oldest son just bought a 32gb WiFi iPad 2 so I asked him to run two speed.net test with the app on his pad. Then I had him pair my Motorola X9HD headset and play music and run two more speed test. Then had him turn off Bluetooth run two more speed test and then connect to the headset and run two more.

The results without Bluetooth connected and working was at 3.2 down which is good out here in the sticks with our DSL. With Bluetooth connected and playing music the speed test fell by almost half around 1.6 to 1.8 down. This happen each time we tested on his iPad.

Now my prime falls from 3.2 to .5 to .6 down with the Bluetooth connected and active. The interesting thing is that on his iPad and my Prime the upload speeds were not really degraded. They're usually about .6 up and that is what it stayed. I would have expected upload speed to be impacted equally.

Has anyone else tested against an I pad?

OK. Just tested my youngest sons 32gb 3g WiFi iPad and his iPad would get 3.1 down when not connected and 1.2 when connected to my headset FWIW. Interesting the 3g ipad had a little worse performance than the wifi ipad with the 3g ipad having the RF window.

It appears that the wifi being impacted by Bluetooth may just be a reality. My only complaint is how much the prime is impacted. If Asus can tune this a bit to be comparable to the results my sons' iPads are getting I would be satisfied.
[Asus  Eee Pad Transformer Prime] compuw22c:
Gotta be streaming/listening to audio, at least that's been my experience. First noticed it by ACCIDENT before coming upon this thread, trying to play plex in my basement while listening with BT headphones. Stuttered to unusable. I believe if I lower the bitrate enough data will make it through, but I shouldn't have to.

My theory is it is increasing noise, thus affecting SNR in the process and generally making more interference for wifi to talk through. If I'm standing right in front of my router, the effect is almost unnoticable at all (granted I only have a 12mb line). At my router, playing music w/ a2dp, 12mbps. Hallway adjacent, same, bedroom, starts to drop to 6mbps. Closet in that room (trying to simulate basement without being cold) drops to about 2mbps, and even then if you look at the graph in speed test you can see it 'bursting', that is, it gets some through at a decent speed, stutters a bit, gets another good go, stutters...
[Asus  Eee Pad Transformer Prime] techjunkie9194:
No expert but with my Bluetooth on my wifi is not impacted, I still get around 3.2 down. If I connect to my Bluetooth headphones it only has minor impact. Speed test goes from 3.2 to between 2.8 and 2.9. If I play music that is when it falls off the cliff down around .5 to .6 for me.
[Asus  Eee Pad Transformer Prime] Gary Key:
What BT speakers are you using and router?
[Asus  Eee Pad Transformer Prime] demandarin:
it was discovered from ipad2 thinner design, that ipad2 wifi performance is actually worse than ipad1. ipad2 relocated the wifi antennae near the speaker grill. there wasn't enough room to keep in it the same location as the ipad1 since the ipad2 was a lot thinner. Relocating it to the grill still allowed reception but definitely decreased in quality from first generation.
[Asus  Eee Pad Transformer Prime] Gary Key:
Good Day from ASUS.

We are investigating the WiFi/BT problems now and hopefully will be able to quickly replicate the reported problems so we can determine a fix. I am working directly with a couple of users now and have corrected one issue by changing their router setup but I am waiting on specific BT devices to assist the other user.

I would like to PM additional members so we can get specific setups including BT devices, routers, user setups and general answers on when the problem manifests itself. If you are willing to provide this information, please PM me so we can further discuss your problem.
[Asus  Eee Pad Transformer Prime] compuw22c:
Dude, I know a lot of people are frustrated around here now, but REALLY, THANK YOU so much for coming on here and opening a dialog with us. Don't know about the rest of the guys here but for me, it's the single greatest PR move you can make (not that fixing the problem wouldn't be nice but, ya know, one step at a time).

That being said you can see my results in previous post. Right at router, almost no issue. 1 or 2 rooms away though, where typically without BT I would see a full 12mbps that my ISP offers, it will drop to anywhere between 5-2mbps, and the worse it gets the less consistent it gets (graph in speedtest looks like the rocky mountains if ya catch my drift). My headphones/headset (being used in a2dp, while attempting to stream plex from local server) is a Plantronics 903+. Any other info I can help you to help me with feel free to PM. EDIT: Forgot to add, router is Asus N-16 running DD-WRT with...um...'correct' settings (networking's my specialty, so it should be all good, though if you'd like an entire config file and/or screenshots of router configs let me know).

Thanks again man, nice to see people making an effort, in the land of hackers of all places :)
[Asus  Eee Pad Transformer Prime] setite:
This is kind of rude. You can google his name. Also I am one of the people who is in contact with him via e-mail. He is an official employee whose job is community marketing or something like that.

As per his latest request, here are my wireless settings.

Nice. I was looking at that router. I decided on the Cisco Linksys E4200 for DD-WRT.
[Asus  Eee Pad Transformer Prime] techjunkie9194:
I PMd you hoping this is for real. I would be glad to assist.
[Asus  Eee Pad Transformer Prime] The_Ninjak:
Personally, it's a great comfort for me to see Gary Key here. He's been a very kind and helpful resource to me and many of my fellow Asus laptop owners in another forum I frequent. Many of them will happily vouch for him with his history of helping investigate problems (like keyboard lag issues), testing patches or BIOS updates, and looking into RMA delays. And he does his best to keep us informed of the progress of such things when able.

Thanks for looking into this issue for us, Gary! It's appreciated.

Ok, just tested out this issue. With BT turned off, speedtest is normal at about 12Mbps.

When I turn on BT, all is still ok, but when I pair it up with my headset wifi almost completely drops out. Speedtest won't even connect to the network. Once I turn BT off again, all is back to normal.
[Asus  Eee Pad Transformer Prime] jerrykur:
BT and Wifi can both use the 2.4 GHz frequencies. Check this post in the Mac forums on the issues and some suggestions for fixes.https://discussions.apple.com/thread/2730693?start=0&tstart=0
[Asus  Eee Pad Transformer Prime] joeshmoo:
m

Exactly my experience. Though it seems like the interference becomes more severe if you get a greater distance from the router. Sitting in my living room 2 yards from the router I'm about 15 Mbps up / 8 down with BT disconnected. Connecting it slows to 2-6 Mbps down and a sparratic 1-8 upstream.

If I walk 5 yards away through 2 walls my speed weakens with BT disconnected, but if I connect to a BT device then Speedtest will either not connect or return in the vacinity of 50 kbps.
[Asus  Eee Pad Transformer Prime] the_game_master:
I get the issue even at 5 feet from my router in my bedroom, from my bed. Netflix playback goes to a screeching halt over paired Bluetooth.
