wi-fi and bluetooth not working simultaneously

Solution 1:

You can fix it by turning off bluetooth and wireless coexistence.

Run in terminal

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

and reboot.

It looks like kernel developers have overdone that functionality slightly ;-)

This setting can be always undone by

sudo rm /etc/modprobe.d/iwlwifi-opt.conf

You can read this to understand what it does

Solution 2:

Run the following command:

echo "options iwlwifi 11n_disable=1 bt_coex_active=0 power_save=0 auto_agg=0 swcrypto=1" | sudo tee /etc/modprobe.d/iwlwifi-options.conf > /dev/null

It worked for my ubuntu 16.04 like a charm.
