[Asus  Eee Pad Transformer Prime] BUYMECAR:
Excuse me for butting in, but I haven't seen one report of BT/WiFi working fine in unison from anyone who actually tested it when the Prime was actually paired.

After toying w/ the settings on my router, the WiFi performance alone on my Prime has been decent, but the BT vs WiFi issue is more than apparent. We're talking drops from 23 Mbps to 800 Kbps upon pairing.
[Asus  Eee Pad Transformer Prime] nunyabiz:
I have the same issue and will update this post when I get home from work. Wanted to stream Google music through blue tooth, but the connections crawls causing dropouts..
[Asus  Eee Pad Transformer Prime] dbtorreliob:
I recently ordered my transformer prime from best buy the grey 32gb on the 5th of this month. I should be picking it up today or tomorrow and the worse case scenario friday. I am thankful to have someone as vocal setite and guys on the other forums posting all this info. It saves me the time and hassle of having to troubleshoot when i can go straight into testing for the known issues. I def will be trying out the bt a2dp profile while streaming some 'hd' video from the intertubes and getting back with a yes or no on whether the issue is reproduced or not. Also, the beauty of all of this is, these issues are so well known that it makes it easier to return the device to bby and wait for something less buggy, like the higher res version or a redesign of the backplate!
[Asus  Eee Pad Transformer Prime] zoro25:
All OK including WIFI and Bluetooth paired

Serial = BC0KAS04xxxx (xxx = numbers)

Mine is a UK model (so euro batch)

WIFI Speed with bluetooth paired to my SGS2 slighly increased.

5 tests carried out with bluetooth paired..

It should be noted that in every one of my total 15 tests.

download speed was lower than my SGS2 however upload speed was always higher.

obviously on same WFI network and tested connected to same speedtest server.
[Asus  Eee Pad Transformer Prime] nyijedi:
OP, you are awesome. Thanks so much for this thread.

WiFi and BT issues aside, how was your WiFi speed and range? Was it decent without BT, or were you one of the ones who was stuck between 0.5 and 3 Mbps most of the time?
[Asus  Eee Pad Transformer Prime] 3rdamention:
Yeah, the way I look at it, there may actually be 2 "Bad Units" that were shipped, each with there own issues.

Is there any verification that all of these Primes that will not install one single update, they show there are no updates even though they are stuck on the stock firmware version, that have Serial Number Unknown, are the same tablets that are considered the "Bad Tablets"? If not, add the "Serial Number Unknown" tablets to the list of "Bad Tablets."

If these are seperate issues, then Asus sent out 3 units different units:

Really Bad Units - These units have "Unknown Serial Number" in the Status and cannot download and update any new firmware. They also are missing something that DOES NOT allow them to be rooted. Finally, they will not play certain Apps since there appears to be something missing and not loading when they power up.

Bad Units - With poor Wifi & GPS

Good Units - Known Serial Numbers, better performing Wifi and GPS.

This is the way it is appearing to me!!
[Asus  Eee Pad Transformer Prime] Turbo8psk:
I have found little difference with my speedtest with Bluetooth on or off.

TF 201 with ICS 4.0.3

Serial: BCOKAS015xxx

Download	Upload	Latency Location
WIFI ON , BT ON |	30287kbps	9431kbps	28	Toronto, ON
WIFI ON , BT OFF | 30225kbps	9434kbps	29	Toronto, ON
[Asus  Eee Pad Transformer Prime] nunyabiz:
You have to be paired with something, not just BT on.
[Asus  Eee Pad Transformer Prime] ModestMuse23:
I'm sure glad we have @setite on the case.... What would we ever do without him?
[Asus  Eee Pad Transformer Prime] Turbo8psk:
With the BT ON im paired to my BT headphones. Just verified again, speed is the same as posted.
[Asus  Eee Pad Transformer Prime] Ciddy:
German 64GB grey unit here:

Ping D/L U/L

27 ms 17.3 MBit 8.1 MBit WiFi on, connected, BT off, REFERENCE

33 ms 14.6 MBit 8.0 MBit WiFi on, connected, BT on, not connected

47 ms 3.0 MBit (!) 3.5 MBit WiFi on, connected, BT on, rcving file

Unit serial BCOKAS044XXX

So when there is an incoming transmission via BT on the device, the WiFi connection loses 85% performance.

Will try out a headset later too.

Hmm, just tested my Galaxy S2 against it, when transferring a file it also loses as much performance. Gotta try the headset I guess before jumping to conclusions...
[Asus  Eee Pad Transformer Prime] Spidey01:
Well, if perhaps the WiFi/BT pain is just a bad batch (or several) hitting the wild and ASUS knows enough upstream about it, it might be possible to get these things RMA'd and replaced with current HW.
[Asus  Eee Pad Transformer Prime] demandarin:
that was funny. he got you there OP..lol. I think OP did say unless Asus does something to help him fix the issue. ;)
[Asus  Eee Pad Transformer Prime] U Flippin Idiot:
Mine is BCOKAS03xxxx and I have no issues with anything. GPS works decent, wifi is a little weak compared to GS2 but not bad.
[Asus  Eee Pad Transformer Prime] nxp3:
Asus is not going to do that because many people who don't think they have a problem will just look at the serial number and send theirs in. Only way is to compare serial numbers for ourselves....but yeah....don't know if I want to post that.
[Asus  Eee Pad Transformer Prime] parker7:
great find.

I'm in two minds over buying the prime because of the isssues. So, it seems if I hang on and wait for Amazon UK to get new stock or let the other models sell out, hopefully I'll get one of the newer batch. Or, are the new batch already out there and selling? think it's safe to dip now or later? hmmm
[Asus  Eee Pad Transformer Prime] federer:
what I meant to say in my first post is that my sons transformer has much better wifi range than my prime, but still not as good as my galaxy 10.1.. anyway. I tested the wifi before Bluetooth and scored 11568 down load and 5259 upload. the scores with Bluetooth on where the same, unless transferring a file. I sent a photo from my phone to the prime and my speed dropped to 350kbs download..... so it seems I got one of the bad primes. Does anybody know if the newer primes have better range? I bought a amped wireless n 1000 smart repeater, but it was no better than my Cisco e2000. I just having only two bars of wifi signal if I'm more than 15 feet from my router or repeater, while my galaxy 10.1 had full bars in the driveway.
[Asus  Eee Pad Transformer Prime] Aluminous:
My serial is BCOKAS037XXX. (US prime, received Dec 29)

I ran several speed tests and got around 30Mbps with no BT, 3-4Mbps playing local music over BT. I also tried another speed test and found the same: With BT wifi seems to max out at 3-4Mbps.

gpstest with BT off gets a 45ft lock fairly quickly (signal isn't great). With BT on it shows at most 1 intermittent satellite, I gave up waiting for a lock... :mad:

I'd like to know if anyone else can confirm better WiFi/GPS+BT results. At first, I thought mine didn't have issues since Google Music and YouTube work fine in conjunction with BT, and Google maps locked on to my location via my WiFi.

Edit: I should note that my Epic 4g loses a little speed when using A2DP, but the difference is marginal.
[Asus  Eee Pad Transformer Prime] setite:
With BT Off or even On but not paired my WiFi speeds are fine. They are on par with the TF101. My range may be slightly less, but I just mean that on the outer edge of my wifi in my driveway its not as snappy and doesn't have the same bandwidth.

To be honest I have been so engrossed in my BT issue that I haven't followed the serial number issue. My unit works fine with regards to the serial number and updates.

I detect a hint of sarcasm. Oh why for?

Like your name. If your unit displays no issues with BT actually transmitting a2dp then please put your partial serial and specs in.

Thanks
[Asus  Eee Pad Transformer Prime] dpwhitty11:
My serial is BCOKAS008XXX.

Wifi speeds are great, GPS was borked on HC (haven't tried with ICS, but don't expect anything to happen), can't report on wifi+bt as I have no way to test that.
[Asus  Eee Pad Transformer Prime] setite:
A nice way another user mentioned was to try transferring a file over BT and speedtesting while doing that. It's still surprisingly difficult to transfer files over BT but if you set both your TF201 and your phone/PC into discoverable mode AFTER pairing it should work after a few tries. Try a decent sized file even though BT is slow as **** for file transfers. Maybe record a 30 second video on the tablet and try to send it to your phone. While its doing that do a speed test.
[Asus  Eee Pad Transformer Prime] fazerrider:
Curious,

With BT on I have a half ping-time, a 30% better WIFI throughput (DL) and the same upload speed. I have ICS 4.03 installed.
[Asus  Eee Pad Transformer Prime] dpwhitty11:
Yeah, I figured I could move something like that. I'll bluetooth a movie or something.

i Probably won't see much of a change if there is any, the network I'm on is utter ****... But I'll report back with 5 tests of wifi on & bt off and 5 more with wifi & bt on.

*EDIT*

Posted screenshot of results.

Ping is a little worse (~20ms), but speeds unaffected.
[Asus  Eee Pad Transformer Prime] nyijedi:
Has anyone suffering from this problem tried changing their router to use only 802.11g instead of 802.11 a/b/g/n? There's a discussion going on in another WiFi thread where the Prime gets noticeably faster speed using 802.11g. In my case, at at the same location in my apartment, I get 4-8 Mbps using 802.11 a/b/g/n and 13-16 Mbps using 802.11g. My other devices (iPad 1 and laptop) pull the same speed regardless of the WiFi setting. I'm not saying that crippling your WiFi network is a solution, but I am curious as to whether it plays a part in the big speed dropoffs when using BT.
[Asus  Eee Pad Transformer Prime] setite:
How, on God's Green Earth, can you have pings that low and speeds that slow?!!!! At those speeds it might not be possible to test.
[Asus  Eee Pad Transformer Prime] Dhyneland:
I never use bluetooth but want to contribute to the testing.. my wifi doesn't seem that bad.. but its not near as good as my wifes iPad2..

Here are my two. I tested with Motorola S9-HD headphones and streaming music via Google Music. That's all I have to do so show the problem. This happens on both my home and work networks.

Gray 32GB

BCOKAS12****

Has the problem. Won't bothering posting scores because when I'm streaming music over Bluetooth Wifi simply stops working.

Champagne 32GB

Received 1/30/2012

BCOKAS02****

Also has the problem. Same performance as the Gray.

I had another Gray that I returned, didn't get a chance to check it.

You can't just pair BT to run the test, you need to actually stream some audio. Pairing by itself doesn't cause the issue.

We have a firewall. (I'm too lazy to make my server at home into a proxy... lololol my fault there)

These tests were done using the wired connection*, too!

Canadian CBIL model (grey 32gb)

Just turning on bluetooth and linking to my external speaker (creative d100) is enough to kill my wifi. I can't browse at all while it's active.
[Asus  Eee Pad Transformer Prime] BongoBong:
hmmm seems like nobody else has the same BBOKAS as the op? Mine is also a BCOKAS as most seem to have.

Despite him saying its your batch thats bad, it seems like most even with a different serial are having BT issues as well. Would add some data but don't have anything bluetooth to hook up!
[Asus  Eee Pad Transformer Prime] Fox1966:
Mine is also having the same issue: simply pairing blutooth with my phone causes my WiFi speed on the Transformer Prime to drop from almost 20mbs to between 3 and 5mbs...My serial# starts with BCOKAS0...
[Asus  Eee Pad Transformer Prime] The_Ninjak:
I never use Bluetooth for anything and own no BT accessories, but I could pair with my Asus laptop or my cell phone to test this out while doing a file transfer or something. I'm one of the few who seem to have gotten a 64GB Prime, so I'd be happy to test my amethyst one out when I get home this evening.
[Asus  Eee Pad Transformer Prime] wynand32:
I'm not convinced that this is a batch issue. I think there's either another inherent radio flaw, or a driver conflict. Either way, I think every Prime has the problem.
[Asus  Eee Pad Transformer Prime] :
I believe I have the same issue. Everything is fine on just wifi, but once i pair it with my phone, my speed noticibly drop. I havent run any speed test yet, but i will once i get home.

And the GPS is just bleh

My serial is: BBOKAS062XXX
[Asus  Eee Pad Transformer Prime] BongoBong:
I tend to agree. The fact that so many people with different serials are experiencing the problem seems to indicate its probably not a batch problem.

It is weird that no one seems to have the same starting serial as him though (granted not a huge pool of responses yet). Perhaps there was something wrong with his batch but I am not so sure it is causing the BT problems.

Edit. Just as I post this another BBOKAS comes up! lol
[Asus  Eee Pad Transformer Prime] jzen:
Um... they all have bad Wifi and GPS.... its due to the metal backing.

I do believe there is a bad batch that have light leakage, loose casing and slow performance. But wifi and GPS is an issue on all primes currently out.
[Asus  Eee Pad Transformer Prime] dpwhitty11:
About the wifi: you sure about that? Mine is on par with my laptop...

Don't assume they're all bad. It's only a handful.

Note that the majority of posters are the ones saying something is wrong. Most people won't post and say "oh hey mine is great kthxbai!"
[Asus  Eee Pad Transformer Prime] djkinetic:
just received mine that shipped from Best Buy and all is good got a serial number: mine is BCOKAS12xxxx. I didnt list the whole number for obvious reasons. Anyway its downloading the OTA right now. Hope it takes =).
[Asus  Eee Pad Transformer Prime] wynand32:
Have you run the test as outlined here? That is, streaming audio to a Bluetooth device and checking wifi?

I've had three Primes so far, each ordered at different times and seeming to come from different batches of deliveries. Each one has demonstrated the problem. I'd have to have had some pretty bad luck to have experienced precisely the same problem with three different units when it's "only a handful" of devices that are experiencing it.

Edit: reading your post, I see that you were responding to a different position. I'll note that all three of my Primes also exhibit the same wifi performance as poorer than other devices on my networks, along with the GPS issue.

I think it's fair to say that wifi and GPS performance is relatively lower on Primes across the board.
[Asus  Eee Pad Transformer Prime] NefariousNipple:
Same issue here

Tried my prime. Speeds with just wifi on 17/4.35, 12/4.47, 11.75/4.54. speed with bluetooth headset connected 0.57/3.88. makes using apps like teamspeak impossible.

BCOKAS08xxxx

Going to be sending this back I think, and wait for a better alternative.
[Asus  Eee Pad Transformer Prime] jzen:
I don't assume, i know for a fact that all primes have these issues.
[Asus  Eee Pad Transformer Prime] z33tec:
My Wifi speed was the same with BT off and with BT on and paired to my Blackberry. Around 17-20Mbps either way.
[Asus  Eee Pad Transformer Prime] Lao Mayer:
BCOKAS04xxxx, I'd say no problem. Streaming through BT to a Creative sound speaker system, Speedtest.net shows a little above 11 MB download speed whereas w/o BT it shows under around 12-13 Mb.
[Asus  Eee Pad Transformer Prime] nyijedi:
I feel like a broken record with this, but I'll say it again. The Prime's WiFi is on par with all other devices when it's close to the router. The issue is that as you move further from the router, the Prime's speed drops significantly more than other devices.
[Asus  Eee Pad Transformer Prime] Hockey37:
S/N: BCOKAS03........

WiFi Speeds are the same with BT off, BT on, and paired with my AT&T GS2. (about 16MB)

When transferring a 155MB video from my phone to the Prime via bluetooth, SpeedTest on the Prime shows about 3MB down, same up. While transferring this video, I am still able to stream music (using my Prime) from Google Music with no hiccups.

Also, just tested sending a 5MB PDF file from my Prime to my phone via bluetooth. Same results, speed tests on the Prime show about 3-4MB down.
[Asus  Eee Pad Transformer Prime] dpwhitty11:
I tested this with my laptop, both now and when I first got it, and they both read almost identical.
[Asus  Eee Pad Transformer Prime] CDN_Chris:
BCOKAS01 - interference is present w/ BT streaming audio 30' from wireless G AP to the point of being unable to see the AP as within range, pausing audio streaming returns to situation normal - mediocre wifi.

I'm hoping this is a batch HW problem but I don't think so.
[Asus  Eee Pad Transformer Prime] rootusr:
Interesting, this can be really useful for asking ASUS a solution for every problem in the Prime, here is my info:

I got mine at December 24th in a Frys store in California. (not online) the grey one of 32GB.

Serial number is: BCOKASO2XXXX

Build number IML74K.US_epad-9.4.2.7-20120106

Other than a poor reception of GPS satellites mine does not have any other reported issue, I upgraded to ICS the day that was announced by nvidia without any issues.

WiFi Working fine

Bluetooh seems to be fine but I don't know an stadard method to test transfer speeds.

No Screen Flickering

No dead pixels

No random reboots (no even one so far)

I propose to create a new thread with a defined set of tests to perform in the prime and asking every user to post information of HW and software to help to determine which ones have a problem.
[Asus  Eee Pad Transformer Prime] wynand32:
Just a reminder, the problem isn't with BT just on and paired but with BT actually streaming data to a BT device.
[Asus  Eee Pad Transformer Prime] Godswrath:
^This.

Since we seem to be unable to find even one person who says they have no problems with wifi while transferring over BT, it makes this theory seem very unlikely. (Unless all released Primes are old HW and they haven't even started releasing the new HW)

And here's our answer: http://xdaforums.com/showthread.php?t=1440187

/thread? lol..
[Asus  Eee Pad Transformer Prime] wynand32:
I'm going to go ahead and note that my Samsung Epic 4G Touch demonstrates much of the same kind of problem as my Primes. BT connected and streaming significantly impacts wifi performance. So, I now have two devices that demonstrate the same issue, meaning that this isn't necessarily something that's limited to the Prime.

---------- Post added at 12:44 PM ---------- Previous post was at 12:43 PM ----------

The issue being discussed in this thread isn't about wifi by itself. My results noted earlier are with my Prime within about 10' of my router with no walls in between.
[Asus  Eee Pad Transformer Prime] CDN_Chris:
The test of streaming audio a decent distance from your AP (30 feet) should provide enough proof if the problem exists for you. You should be able to do this by pairing with a pc/mac/ps3/stereo and using the speakers on the paired device to play music from the TFP. Pausing the stream will stop the interference making it quite conclusive.

The best info will come when the OP gets his replacement and does a similar test. At that point if no interference is found on the replaced device a poll for serial numbers affected or not would help narrow down any hardware differences between them.

EDIT: It's bound to have some affect because they're in the same frequency band, but killing your wireless connectivity within 30 feet of your AP I would say is a problem if you're wanting to use your device that way.

I conducted my test with my notebook in the same room as my AP and the TFP 30 feet away, audio continued to stream while wifi connectivity was lost. This is quite bizarre because BT should be using far less output power than wifi. If Asus made a change that the OP is being advised is hardware it must increase wifi reception or lower BT transmit power.
[Asus  Eee Pad Transformer Prime] wynand32:
So you're saying your wifi is BETTER while streaming audio to a BT device? Or did you mean literally MB (megabytes) vs. Mb (megabits)?
[Asus  Eee Pad Transformer Prime] PossumK11:
I have a 32 GB Grey Prime from the same Amazon ordeal that you went through. The serial number matches yours exactly up to the XXX.

GPS is completely non-functional (using the latest Honeycomb update and the new ICS update). It won't even detect a single satellite outdoors. For reference, my Galaxy Nexus would see 10 satellites and use 9 from the same location.

WIFI is weak as expected, but functional. In close proximity to the router, both the Prime and Galaxy Nexus top out at ~24-30 Mbps transferring a single large file via the WIFI Transfer Pro app to a wired computer. Farther away in my bedroom, through 2 or so walls, the speed decrease is greater on the Prime than on the Galaxy Nexus. Routers tested were the Cisco Linksys E4200 in mixed mode and Trendnet TEW-633GR in G-only mode (necessary because of an issue with Android devices).

I don't have any Bluetooth devices to test that functionality.

This Prime also has some backlight bleed in the corner and three bright spot seen on bright backgrounds. The backlight bleed extended much farther along the horizontal edge, but squeezing the screen and case seemed to have snapped something together and fixed this portion. I will be returning this to Amazon.
