Hi! Maybe this can be a workaround: https://answers.launchpad.net/ubuntu/+question/239371
===================== Try: echo "options iwlwifi 11n_disable=1 bt_coex_active=0 power_save=0 auto_agg=0 swcrypto=1" | sudo tee /etc/modprobe.d/iwlwifi.conf > /dev/null As one big command. Reboot to test. ===================== I also made a change to enable A2DP in my headset. Before, when I switched to A2DP it didn't worked. ===================== This worked for me: 1) Open /etc/bluetooth/audio.conf gksudo gedit /etc/bluetooth/audio.conf 2) find "Enable =..." under [General] and delete Socket fron the list [General] Enable = .... 3) Add this line: Disable = Socket 4) Save 5) Restart the bluetooth service sudo service bluetooth restart 6) Restar pulseaudio for good measure. pulseaudio -k pulseaudio -D 7) Cross Your Fingers and try. ===================== Now I can use my Sony SHB50 on Ubuntu with good sound (A2DP) and my WiFi is working fine.

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?
