Same problem for me when using the A2DP profile with a bluetooth speaker
(SONY:SRS-BTS50), the wifi barely works. When using the HSP/HFP profile
(less quality/mono) the wifi works decently (I didn't do any performance
tests, but when using A2DP the drop in performance is noticed
immediately, I can barely use a browser, intermittently).

I have a Toshiba Z830.

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?
