I found a problem with my kaiser phone last night. The problem is that if I listening to music with my bluetooth headset I am not able to connect to my WiFi at the same time. This problem is specific to A2DP because my headset can be connected to my phone and I can not browse the web with WiFi. Has anyone seen this problem before? Has there ever been a resolution for it?

I've seen this too -- when using A2DP, the WiFi connection goes down & won't re-establish itself until I turn off A2DP. I haven't found a resolution yet -- not that I'm looking for one as I almost never use A2DP, and when I do, I'm in the car, where WiFi isn't too useful.
See my post here which may be a related problem. I assume you have the same new HTC ROM: http://forum.xda-developers.com/showthread.php?t=396409
I have a similar issue. If I am streaming music, from my HP media server, over wifi and using my Plantronics 590A bluetooh headphones, after each song I am asked to log back onto the network and as each song comes to an end my device starts to search for a network connection. I don't have this issue when I use wired headphones. Clearly there is an issue when both bluetooth and wifi are used at the same time. I don't know if it's hardware or software but I'm not happy about it.

HTC TyTN II (Kaiser/P4550)
Rom ver: 1.82.707.0 WWE
Rom date: 11/03/07
Radio ver: 1.27.15.32
WM 6 Professional
CE OS 5.2.1620 (18125.0.4.2)
It's normal. Without going too technical, WiFi and Bluetooth operate on the same frequencies. They will live together if they're not using too much bandwidth, but if the usage is heavy there will be problems.
A BT stereo headset represents a lot of data to send and thus bandwidth usage, which means the BT will use the spectrum heavily, stepping over the Wifi. Due to the many packet losses the Wifi connection cuts.
Other way around, if Wifi is under heavy load, Bluetooth might drop.
Nothing we can do, that's what happens when you pack 2 radios operating in the same frequency band so close to each other, or even maybe sharing the same antenna which might be the case in today's phones.
It is absolutely NOT normal. The reason I know this is that VoIP over WiFi has been running almost perfectly on my TyTN II for a year, until I installed the latest ROM by HTC which broke it.
I used to get no crackle on Bluetooth calls with WiFi turned on. Now I do.
I used to get great quality VoIP. Now it is beyond unusable.
Simply, their new ROM broke it. BT and WiFi used to live in harmony, until their buggy ROM came out the other day. I think there are many users who know this, and who expect a hotfix soon.
You're talking about calls, I assume using the BT headset profile, while the other people in the thread are using A2DP wireless stereo. They're very different in terms of bandwidth.
On mine the headset with WiFi is also fine, but not A2DP. You're apparently not having the same issue than what is mentione in this thread. Yours might be due to the ROM, but the A2DP thing is more likely to be related to what I explained. I could myself experience it with several ROMS (all WM6, never tried a 6.1).

My old TyTn II worked fine with BT and WiFi on at same time - never a problem. I always had WiFi on at home for emails etc... and always have my BT headset (Plantronics 8XX mono) working as I hate holding phone to my ear and get a lot of calls.
I recently bought another TyTn II and then unlocked it using advice form this forum (many thanks to all BTW!) and installed latest HTC rom and WM6.1 etc... Now I love many aspect of the new ROM but I can't use BT and WiFi at same time.
So from my experience it MUST be the new HTC ROM software issue.
Okay, chalk me up as another victim of this Wireless + A2DP = Crap Reception. I've tried three other Radios and the effect is the same.
I was using a rom I got in about April, and I could stream music from the internet over wireless listening to it on my Pantronics 590A's over bluetooth no issues (other than battery lol). Now with a rom I got this month, I can listen to music over bluetooth no problem, surf using wireless no issue but as soon as you mix them both it's all bad. Also, I need to re-pair my headphones whenever I want A2DP, where previously I could just turn on the headphones and have them connect. Also, no headset icon in the taskbar.
It's not a CPU issue as there's no excess usage when you both have them enabled. Personally I'm going to point the finger at the bluetooth stack here.
As far as I remembered when I first purchased the ATT Tilt with my Plantronic Voyager 855 I WAS able to stream via Wifi (Winamp Remote) and use my bluetooth without a problem. It's when I started to put cooked roms in the Tilt that it stopped working correctly...
Besides, I use a Macbook Pro via Wifi only and I listen to my Itune via my Plantronic Voyager 855 everyday. If it's true about WiFi overloading Bluetooth on the frequency. Why does it work fine on the MBP?
And Finally.... to make my point...
I also have an AT&T Fuze. Works fine there. Matter affact. I'm currently connected via bluetooth to my Fuze with my Voyager 855... turned off 3G/HSPDA on the Fuze. WiFi on the Fuze using Winamp Remote to connect to my PC streaming from there. Explain that....
Has anyone fixed this problem?
I'm experiencing the same problem on my kaiser aka xda stellar. When Wifi is turned on bluetooth A2DP stereo connection is dropped.
I got my Nexus 7 last week and have not been able to put it down. Recently I got a bluetooth keyboard to go along with it and it brought some major bluetooth connectivity issues to my attention. Has anyone else had any issues with bluetooth accessories on the Nexus 7?
The problems I have been dealing with:
When connecting to a bluetooth device whatever screen I am on on my tablet refreshes (ie: home screen redrawn, chrome all tabs refresh)
Bluetooth connectivity drops momentarily (tethering or connected to bluetooth keyboard)
I'm trying to figure out if it's the unshielded speakers on my office desk or if it is an actual problem with the bluetooth module on my Nexus 7.
Quick update, I've been able to recreate the issue with the screen refreshing/redrawing when a paired device is connected and disconnected. It seems that anytime you connect or disconnect a bluetooth device it refreshes whatever screen you are on (if it's a browser window where you've filled in a bunch of text on a forum you will lose all of it because the browser tabs refresh as well).
While I have not tested this specific BT setup I can confirm that the BT performance on this device is horrible. Specifically with BT headsets when used with any VoIP app or even Google talk.
I hope it is just a software issue and will be fixed with an update.

Here's a quick video of what's going on with mine. I have another Nexus 7 arriving today so I can test to see if it's just an issue with the one I currently have.

I have been unable to play an .avi movie with a bluetooth headset, it freezes after a few seconds. It plays no problem without it. I have also had issues with the tablet becoming very slow when tethering to bluetooth, at least for number of seconds (> 30), presumably when it got internet and started syncing...but no slowdown on the wifi, so it wasn't the syncing with the issue, but the bluetooth part of the communication, I believe. Anyone else been able to play movies with a bluetooth headset or speakers?
I have had no trouble at all with Bluetooth. My Samsung Hs3000 works great with music,movies and any internet or sys sounds. It Also has a very good range of at least 75ft or more in the open and covers my downstairs when inside.
I have been able to pair 2 headsets. 1st had no function at all, ext. mic did not work and no sound- using groove ip or playing music. 2nd was a stereo bluetooth set with ext. mic. No transmission with groove ip. However, with this one I was able to listen to music.
Also paired with 2 phones. One with JB-( Gnex )and one (Note)with ICS. No data transmission to tablet with either one over bluetooth.
same issue - getting sound on voice
I've bluetooth paired with phone and media audio connected.
I get the sound but not mic.
This is with nexus 7 4.1.1 using novero rockaway headset...it works fine with the ipad.
any ideas? I'm stuck.
Friends ...... , HTC One it seems has a terrible Bluetooth range ....... I have a Logitech BoomBox (Bluetooth spks) and a Belkin Bluetooth receiver connected to my AVR. In both the cases, when connected to my HTC One it looses audio in just couple of feets. Specially with belkin receiver. But when I tested the same with my iPhone 4, it works perfectly, till the Bluetooth's designated range of 30 feet (10 meters) ... with both Belkin and Logitech ....
so it has something to do with HTC One's Bluetooth.
People with HTC One and having any Bluetooth audio device, please test this and report if you are also facing the same issue, Or is there something that I can try to increase the range. Its pathetic, 2-3 feets at the max. I am bitterly disappointed with this ..........
Regards.
Sammy
I think that Android 4.1 had a BT flaw that was fixed in 4.2.
so this means its more of an android issue than HTC One........ any alternatives to improve this, till we have an 4.2 update
I was using bt audio yesterday and it was horrible. I did some googling, try turning off wifi before you connect to the speakers, it solved my trouble straight away. I found if the music was playing when I turned wifi back on it would still be ok. Might help?

Jiggle .... my friend, you made the day for me, how so ever strange may it seem, it did work .... ..... I switched of my wifi and then connected Bluetooth to Belkin receiver and vola!! :victory:... no drop outs and was able to use BT at full 30 feets, and then if I switch on the wifi later all is well.
Strange, if wifi is working before I connect BT, it drops and is very uneven ......... must be some bug, but anyway, solution is not as irritating as one might expect.
Thanks again Jiggle, for you input, saved me a great disappointment.

whew you had me in a panic here. (o; I'm still a little traumatized from my asus T201 wireless issues.
The Wifi/bluetooth issue is a drawback of the aluminum body design of the One. Bluetooth shares an antenna with wifi transmit. I believe wifi receive shouldn't interrupt bt though.
Then there should also be a problem if I switch on wifi after I connect BT. ,... in which case it works. It only creates a problem, if the wifi is first on and then I connect BT. ...... which is strange
Just for information. I had 3 htc, desire hd, sensation, onex and ALL had problem with bluetooth, weak signal, using a headset with the phone in my pocket already failed. I now have a note2 and this problem does not occur, being used in the same situation. So ....

My m7 (TrickDroid, elementalX 0.11 default overclocking and undervolting) is having the BT issue whenever wifi is on, regardless of whether I connect the BT device while wifi is off, and regardless of whether audio is playing when the wifi is turned back on. In other words, on my device, BT really really sucks if wifi is connected, period. Any suggestions other than not to use wifi if I want to use BT?
Update: My router (Netgear wnr2000v3) seems to use 2.4 Ghz channels. Any thoughts about whether swapping the router with a dual-band or 5 Ghz channel router would work around this issue?

I did pick up a new dual-band router and set up the phone to connect only on the 5Ghz band, and it worked! No more bluetooth issues at home. So if you run into this issue, a temporary workaround until (hopefully) HTC/Google provide a fix is to avoid the 2.4Ghz band.
Strangely enough, my Bluetooth range keeps decreasing with each software update. When I first bought this thing, I was generally impressed with how far I could walk from my BT speakers. Not as good as my evo 4g or 3d, but decent. Better than my gs3 and gn2.
Now I tend to make it about 5 feet or so with minor cut-outs while using apt-x. If I put my hand between the signal at 10ft, I can stop it completely. If I touch the upper-right of my phone with my thumb as I hold it in my right hand, I can kill the signal as well. Very much an antennagate going on here just like the iPhone 4.
Afternoon all,
I have the 512GB US Unlocked Note 9, and I have noticed two problems with the phone:
1.. On WiFi at my home (UBNT Access Points running latest firmware/software) I observe very poor WiFi performance on 802.11AC/5Ghz radio. If I switch to the 802.11N/2.4Ghz radio in the same AP, I get near wireline speeds when running a speedtest (about 175 down and 7 up). On 5Ghz, I barely get 7-10 down. No other WiFi devices have this issue.
2. Using Bluetooth audio in my truck (Dodge RAM with UConnect running latest firmware) I get audio dropouts/stuttering of about 1-2 seconds every few seconds, but this only occurs about 50% of the time. Sometimes it works flawlessly. I have no BT audio issues whatsoever when I pair my iPhone XR to this stereo.
Is anyone else having these sorts of wireless issues with their Note 9? The cellular/LTE speeds appear to be performing quite well and is very fast in an area with a good signal.
Thanks!

Hello,
from MIUI 11 i am experiencing issue with BT devices disconnecting while using wifi hotspot. Once hotspot is active everything works for a while but then BT stops working and disconnects devices.
IT IS present Also in custom roms. Anyone Has this issue and know about some fix?
Many thanks.

Is your hotspot in the 2.4 GHz band ? If the answer is yes, try 5 GHz.

i will try, but unfortunately the client devices does not support 5ghz
i think it's a hardware issue as it does it with every, also custom roms...

It's mostly unrelated (at least with phone) but I recently started using a new small PC. The bluetooth disconnected too easily, even at less than 2 meters, a slight move of my head(phone) was enough to cut the music. Then I disabled the Wi-Fi interface and Bluetooth connection became robust even in the next room several meters away. That's probably because Wi-Fi and BT uses the same 2.4 GHz band.
Concerning Xiaomi smartphones, I use them everyday to listen to music while Wi-Fi is on (either in the 2.4 or 5 GHz band) and never observed a disconnection (xiaomi.eu or other custom ROMs). But I haven't tried in hotspot mode.

yes it's work as it should until i enable the hotspot, even then, it works sometimes for like an hour and then it starts... solution is airplane mode on/off and it works for a few again.
i use this a lot, as i do hotspot for kids and wife in the car, and i also work a lot remotely and this disconnects everything from BT audio to watch and it's really annoying. :/

I just made the test, phone connected to LTE and my home routeur in the 5 GHz band. Then connected in aptX HD to "PLT Focus" headphone. After that I turned on hotspot in the 2.4 GHz and I havent observed a disconnection yet (after 15 minutes). But I live in the countryside where the whole Wi-Fi spectrum appears almost unused. I usually can detect only one other access point with a very weak signal. So, even if I was able to test for several hours, it wouldn't prove anything as your use case is very different. It may come from interferences on the same channels used by others while your vehicle moves. I don't know if we can control what channel is allocated by the hotspot but it's probably dynamic. I guess that when you switch off then on, it just select another less used channel then it works again for a while.
