Alright, so I've heavily tested this with a ton of bluetooth devices and 5 access points, both 5Ghz and 2.4Ghz.
When I have both wifi and bluetooth on, with the device connected to both services (both a BT device and an AP) neither radio works. WiFi says connected, but doesn't load anything, can't ping out at all. Bluetooth will find the device, connect, and disconnect within a few seconds.
I tested the same devices but only using one radio at a time and all the BT devices stay connected with WiFi off, and all APs are connected and load data with BT off.
Does anyone know what's going on? I've suspected this to be an issue since 4.0, but it's still around in 5.0.1. It's persistent across ROMs and RUUs, so it can't be a rom issue. Currently I'm on Viper 4.6.1, S-off, SCID (although this happened before I S-Off'd as well)
Does anyone else experience this issue? Any potential fixes?
I run into something similar periodically...
My 5ghz wifi always works no matter what.
2.4ghz / bluetooth will work for 2-3 days... then it stops... no 2.4ghz SSIDs show up in wifi and no bluetooth device will connect... Even turning BT/Wifi/Airplane on or off in any combo. Only a reboot will fix it.
My friend also started having this issue.
I've been all over and no one has a solution. I use an android wear device, so bluetooth is necessary :/

I have an HTC EVO 4G running FreshEvo 4.1.1.0
The WiFi was working fine without a hitch until recently. It seems that since I upgraded to FreshEvo 4.1.1.0 and updated the radios with the patch, that this is when the problem started.
Now, the WiFi connection "locks up" intermittently and I have to reboot my TrendNet TEW-633GR router so that the phone will connect to it again at least for awhile.
The symptoms are: The WiFi connection with my home router will be fine for awhile. Then, it will not work.
I still get an IP address from the router and the WiFi settings says it's connected. But the connection doesn't work until I reboot the router. But the router isn't really the problem because other phones and my laptop can connect to the router even if the HTC cannot.
To the best as I can tell, the WiFi connection on the HTC locks up when:
A) I run the Roku Remote Control app and something unexpected happens like the app does a force close. The Roku Remote app uses Telnet, I believe.
B) I'm connected by WiFi at home, then leave and the phone switches to 3G. When I come back home, the WiFi between my phone and my router is locked up. However, if I connect to WiFi at another location, it works fine at the other location. Also, I can still connect to my home router with WiFi from my laptop or another phone.
Does anyone have this problem too, or a solution?
Thanks

I would have a go at flashing an alternative radio ROM onto the EVO first. This should be pretty simple if you've already changed ROMs and have a custom recovery.
Hi!
I try to discribe the weird behaviour of my GNex.
Everytime I use Spotify or TuneIn Radio over my home WiFi und stream the Audio via Bluetooth I have massive buffering pauses.
The strange thing is - this only happens with the GNex and in this particular setup.
Spotify on Wifi and listening with cabel earphones works flawless.
Bluetooth streaming in the car while being on 3G also works without any problems.
And with my other Android devices (Transformer 101 on AOKG and my Galaxy S on CM9 nightly) even the combination being on Wifi and streaming Audio with BT to my BT boxes works without a problem.
(For absolute confusion - somehow I don't have this buffering problem when using Play Music).
The Wifi connection itself or the bluetooth connection are tested - the error must be somewhere else.
Question: Is this problem reproducable with other Galaxy Nexuseses or is it my particular setup / device that acts a bit funky?
Bonus Question: Does anyone of you know a solution to my problem?
Thanks in advance

Are you connected to a 5ghz or 2.4ghz router?
The router (AVM fritz.box 7270) can handle both bands. At the moment I use the 2.4Ghz band because I still have a few Wifi devices can't run n-Standard Wifi.
Update:
I played a little bit with the settings and found out that if I force the screen to keep on, streaming over BT through a Wifi connection works.
I checked the Wifi policy but it was "always on" when phone goes to sleep...
Update 2:
Tried to change network to 5.0GhZ and - yes - it solved the problem!!!!!!!!!!!!!
Thanx a lot for the suggestion!
But as I said, it's unfortunately no suitable solution for me because my Transformer (the original one) only works with 2.4GhZ networks. The "screen on workaround" still works for me, but is a huge battery drainer. Well, of course... with WIFI, BT on and working and screen on...
So if anyone has an idea why its working with screen on and not working with screen off... plz...
I have the same issue. Wifi streaming via Bluetooth starts massive buffering when screen locks. It also happens on my Nexus S (ics). My girl friends exhibit (ginger bread) has no problems. I guess it's an issue with ICS.
Galaxy Nexus: Settings -> WiFi -> Advanced -> 5Ghz only
That might fix it, although it won't work if your nexus also needs to connect to 2.4Ghz WiFi networks.
Also download "Wakelock" from the Play Store, and find if one of those wakelocks will fix it.
A Wakelock tells Android that it isn't allowed to sleep as long as the wakelock isn't released. Just try all of them, maybe it'll help.
Thanks for the tips. The 5ghz range on my router sucks, but I'll give that and the other tips a try. I got some Bluetooth speakers for around the house which are awesome when not buffering.
Hi
I have upgraded a few months ago to Samsung's ICS 4.0.3 stock rom but rooted on my 989, and have noticed that when I pair my bluetooth headphones and begin listening to music, the Wifi hotspot cuts out (ssid disappears, lose IP address on computer). This case is also reproducible if I do the reverse. Eg. Start fresh (BT headphones not connected), and I start my Wifi hot spot, get the PC, or playbook or other device to connect to the Wifi. I can ping -t google or similar, without issue or any interruptions. The second I turn on on my bluetooth headset and it connects to the phone, the ping takes a dump, times out, and I lose IP connectivity to the phone's 192.168.43.1 IP. My BT headset is the RF-MAB2 for what it's worth, and this issue does not happening when using regular 3.5m stereo headphones in the headphone jack.
Is there any known solution or work around to this? I don't recall this being a problem in Android v3 honeycomb, as I did the exact same thing without issue.
Any ideas or suggestions? Can I somehow pull the tether Java jar app out from honeycomb and use it in ICS?
thanks,
Jonathan
edit: fixed some spelling whoops.
Before you go ahead and pull an app from an older Android version check to see if you are having the same issue with another Bluetooth device connected with your phone. I am on a custom ROM so I'm not able to reproduce your issue. Although, I have been able to use a PS3 controller through Bluetooth to my phone while Wi-Fi was on, without Wi-Fi losing connectivity.
Also, if you have a capable router, try changing between 2.4GHz and 5.0GHz to see if that works. Even though Bluetooth is using a different frequency, there is a chance that it is interfering with your Wi-Fi signal, especially if you have a lot of devices connected to the router at the same time. You can also try changing the channel of your router and see if that does anything.
There may be other solutions but what I have mentioned is worth attempting to start troubleshooting your issue. Good luck!

Thanks for the suggestions, I will look for another BT device; I hadn't thought about that one. I usually only use tethering when im away from home, so there aren't any SSID's that show up in the wifi networks that should be interferring. Perhaps your onto something with my specific BT device and the new ICS not liking something about it, I will try an ebay ad2p / bt 3.5 mm adapter and see if it works any better, as they're cheaper than ~50 for a trial and error at futureshop.
Let me know if anything else comes to mind - thanks
I use my GPAD along with a nice bluetooth headset when I exercise. After the upgrade to 4.4.2, I started experiencing wifi connection drops. The only way to reestablish the connection is to toggle airplane mode, disable bluetooth or reboot the tablet. As long as I have bluetooth disabled the connection is consistent but if enabled, the connection drops within 15 minutes. Has anyone else experienced wifi drop outs with bluetooth enabled?

...and have always assumed that there will be a problem when streaming to my BT headset (which I do often) and try and use Wi-Fi at the same time. This happens consistently and so I just tend to no longer bother.
Actually I now use my Nexus 7 (original) just for BT streaming and the G Pad for other use when a Wi-Fi is needed.
Whenever I have both bluetooth enabled (and paired with any device) and wifi enabled, and I'm streaming music (Spotify in my case), after several minutes (almost randomly), the internet will stop working. Meaning, the WiFi icon will still show as connected, but it can't connect to anything online. I typically have to disable and re-enable WiFi for it to work, but then it would do the same thing again.
The strange thing is, my Galaxy S4 had the exact same issue/behavior. On both devices, I've seen this behavior regardless of the type of WiFi connection and/or bluetooth device (I've noticed it with my skullcandy headphones as well as my Sync in my car).
Do these devices share the same bluetooth/wireless chipset? Is it an Android thing? I'm forced to either use 4G with bluetooth, or WiFi with wired headphones. Thanks.
EDIT: this is using 5ghz Wifi.
What version of android are you on ?
carrier phone or unlocked. Some times these issues are carrier specific and non existent on others.
If you go into settings - wifi
Uncheck any option that says switch to data if wifi is unavailable.
I can confirm that this is an issue, I experience the same problem on my g4 818p

WiFi goes on 2.4ghz or 5ghz(most commonly on 2.4ghz) Bluetooth works on 2.4ghz. Unless you are 1m from router, BT is going to butcher your wlan. Had the same problem before. Solved it by buying dual band modem-router.
You could forcing different channel in wlan settings.
http://smallbusiness.chron.com/fix-bluetooth-wifi-interference-71008.html
idea here is reducing interference to bluetooth from competing sources.
- switch off wifi and use data which the OP is doing. Curious that the problems occur even at 5Ghz. Would have thought that band would be relatively immune to 2.4ghz sources.
- reduce the distance between bluetooth device and phone.
- move away from any sources of wifi interference if wanting to use bluetooth.
And now from the ppposite direction. Preventing bluetooth from interfering with wifi

Read the comments below. similar to the OP.
The key is more management of the problem rather than solution.

I'm using the Verizon variant.
this issue hunted me on all software version
Many options live
Router: Try another chanel
Router: Try only 2.4 or 5 Ghz
Router: Try only N or try only b/g/n mixed
App: Delete tunin radio
Last options send back service mainboard change.
i m facing the same problem but only when i do cellular call,
i am using realme wireless earphone , when i used to call my wifi speed gradually decrease , and after that stop working completely..,
after disconnecting the call i need to OFF and ON to work wifi again....,
My wife got the same issue with a Samsung A40 (and before with a Motorola), when using 2.4 wifi and Bluetooth connections (band and speaker for instance) the wifi is hanging. With wifi 5 it's ok. I don't have any issue with my phone using same network. It's crazy.
