I have recently upgraded by Kubuntu desktop to 22.04LTS version. Everything is working fine except my internet over any WiFi connection is performing awefully dodgy. It works but very inconsistently. Slow speed, frequent drops in connection.

I have windows installed as dual boot. Internet is working fine there. Same I tested on other devices.

I tried reinstalling Kubuntu. Still I am getting same issue. My laptop uses ath9k driver.

Please help!

You can improve BT and Wi-FI coexistence by running

sudo tee /etc/modprobe.d/ath9k.conf <<< "options ath9k btcoex_enable=1"

Reboot and check.

To revert the setting, run

sudo rm /etc/modprobe.d/ath9k.conf
