I can confirm it still exists!

Annoying as fuck! And there is almost no information about this anywhere
on the internet. I was lucky to google this one up, spent lots of time
trying to fix this.

I can not but disagree with you nathan that this is not important, as it
is quite commong that people connect bluetooth devices to their laptops.

As soon as you do this, then you can basically not use the internet
anymore.

What is even more strange is that even after disabling the bluetooth,
this error continues to exist. The only way to resolve it is to restart
the computer.

I will try changing the channel on my router, but I doubt that will
help.

I have an apple trackpad that I would like to use, and I can imagine
people also having bluetooth keyboards.

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?
