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

 

Thank you, Julian!

My wifi problem solved just by entering your first big command.
I'm using MSI GE620 laptop with SE MW600 bt headset. 

And I do confirm, Ubuntu 14.04 LTS couldn't use bt and wifi at the same
time before the fix. Just as Greg posted it.

Title:
  Bluetooth does not coexist with WiFi

Status in bluez package in Ubuntu:
  Confirmed

Bug description:
  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?
