[Bug 219057] Re: Bluetooth does not coexist with WiFi

[Erik Lq]

This "bug"/"behaviour" still exists and is extremly annoying.

Using a SE MW600 headset on a Samsung NC10 this behaviour started to show up a couple of weeks ago.
First it was just for a short while, but now it is consistent...
Right now the computer is running [2.6.32-26-generic #48-Ubuntu SMP] with backported (from compat-wireless-2.6.34)  ath5k module (for testing purpose). The only change when using the backport is that they now supress the "noise floor calibration timeout" message in syslog....great...

So what I am experiencing is that the bluetooth module is interfering with the WiFi module when streaming audio using A2DP.
WiFi speed is decreased and at some points ceased. This goes away as soon as I disconnect the headset.

The issue is was not present a while ago (and if: not at this rate) so I am suspecting that someone updated something without telling "the other guys" (wifi vs bluetooth guys). 
Issue doesn't exist in Win XP, ie hardware should be fine.

Attached output from syslog when this issue occurs.
Let me know if you need more info (and what kind of info)!
