Problem with wifi and bluetooth when they are both turned on

Problem with wifi and bluetooth when they are both turned on - One (M7) Q&A, Help & Troubleshooting

Hi
I'm experiencing an odd problem with my phone. I'm on Skydragon rom (android 4.4.4) and I'm experiencing the following problem (quoted from another site with the same issue):
I have wifi on all the time and working properly, no network drops. I connect my bluetooth headset. Wifi still seems to function properly. Only when the bluetooth is actually in use (ie. listening to music or taking a phone call on the headset) does it seem to disrupt my wifi connection. If I turn my bluetooth headset off, wifi will work perfectly again without any drops.
Does anyone have any insight into this problem? I have tried changing radios, hboot, the works and nothing works.
Cheers

WiFi disables or crackles Bluetooth and kills VoIP

Weird issue with new HTC ROM (version no. below) - anyone else got it or know a fix?:
If I make a BT call with WiFi on, the BT crackles and flits every second.
If I turn off WiFi it is perfect.
If I set WiFi to 'Best Performance', all BT devices are lost and disconnect.
If I set it to 'Best Battery' or the middle setting, BT devices reconnect.
VoIP calls via Bluetooth now crackle themselves to death, because such calls use BOTH Bluetooth AND WiFI simultaneously - shock horror!

(Updated post above with VoIP issue)

i was having the same exact problem, took me couple days to realize it was the wifi. Only thing ive been able to do(motorolla s99 stereo) is make sure my headset is FULLY charged before pairing. And (no fix here) i shut the wifi off when im in the field. There is a bug there for sure. Is it just too much for the phone to track the 3g, wifi, and duplex on the BT?

I have exactly the same problem. BT works great with my headset (Plantronics 8XX) and has good range and is very clear. My WiFi works great and has a good range BUT if I have both turned on my BT is useless. BT devices are not visible more that 30cm away and there is a major crackle even at less than 30cm. Took me a while to work out why my BT headset would not pair with my TyTn II and Plantronics could not help. Used to work with my previous TyTn II OK, so I did a hard reset and then BT paired fine. Then I realised it was simply that hard reset turned off WiFi so I wasted my time doing hard reset when turning off WiFi was solution.
I called HTC and they can't or won't help but they did say they would log it and look into it (do we believe them? ;0).
The BIG PROBLEM for me is using SIP/VoIP as this uses WiFi of course but because of front speaker issues on TyTn II it is very hard to use without a headset and sound it just not good enough most times to use on my unit. So BT headset is the answer but can't work due to this WiFi/BT issue.
I am going to try flashing various different radios this afternoon as some members said this may help but from what I have read on this forum it does not solve problem completely.
If not then it's back to my wired headset and looking like an 80's teenager when I am using VoIP.
Also I wanted to install Navizon and earn points driving around with my WiFi on but this would mean no BT headset so I can't do this.
This really is an annoying bug.
If anyone has a fix or has found something searching the forums that my searches have not found then pls let me know.
Thanks.
