Since upgrading to Ubuntu 13.10, (currently installed 14.04) activating bluetooth makes my wireless extremely slow (halt). I managed to fix the problem recently with the help of this topic: Wifi slows down if I connect with Bluetooth device on Ubuntu 14.10

However, the same problem appeared again today: I can either have bluetooth or wifi but not both at the same time.

Any help would be greatly appreciated!

edit, output of the two commands:

lspci -knn | grep Net -A2

With the iwlwifi module there is a bluetooth coexistence parameter that is set to enable by default but since it doesn't seem to be working for you, we can disable it with

echo "options iwlwifi bt_coex_active=N" | sudo tee -a /etc/modprobe.d/iwlwifi.conf

Reboot and see if it works better
