[Q] WiFi doesn't work when Bluetooth is connected topic

I apologize for the bad title,

When I connect to my Mi Band via BT, my WiFi stops functioning. If I disable BT, WiFi starts working, but then I can't connect to BT. I'm on 5.0.2, and I had CM12, and I also tried Slim Rom, but the issue persisted across both ROMs.

Does anyone have an idea as to what could be causing this?
