[Bug 219057] [NEW] Bluetooth does not coexist with WiFi

[Greg Inozemtsev]

Public bug reported:

On my system bluetooth and wifi are unusable together. I have a built-in
CSR-based bluetooth module in my laptop, and an Atheros wifi. Wifi
transfers slow to a halt whenever there is BT traffic.

For example, if I play a music file from another machine through the
network using a BT headset, only the first few seconds of the file will
play until the player runs out of buffered data. No further data is
downloaded. Web pages also do not download, and I even lose connection
to AP from time to time.

At the same time, it looks like AFH is trying to work. If I monitor the
value returned by 'hcitool afh', it changes. But this seems to have
little effect on connection quality.

Is this a problem with my hardware, or the AFH implementation? Is there
a way to force bluetooth to not use the channels in use by WiFi?
