I am using Windows 8.1 along with Ubuntu 18.04 LTS on a Lenovo G50-70. Whenever I connect my JBL Bluetooth (v4.2) earphone, my laptop's WiFi disconnects after a few minutes. Everything works fine when I am running windows. So this is an issue with Ubuntu. Please, someone, help me with this issue.



I tried this command:



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


but this did not help.

I executed lspci -knn | grep Net -A3 to get my hardware info, and here is the output:
