My wifi internet is very slow when I connect bluetooth speaker. However, in windows 8 internet is fast even if I am connected to bluetooth speaker.

I am using Ubuntu 14.04

Output for: lspci -knn | grep Net -A2; lsusb

This can be fixed by running in terminal

sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi bt_coex_active=0"

Then reboot and test.
