[Solved] Qualcomm Atheros AR9285 frequent disconnect and reconnect UBUNTU 18.04 lts

[subhadeep-sengupta]

Hi guys, I just happened to solve my wireless card frequent disconnection issue. i'm using a Z570 Lenovo laptop and running UBUNTU 18.04.

1. navigate to modprobe.d directory as shown below
cd /etc/modprobe.d/

2. create a new file ath9k.conf as shown below
sudo nano ath9k.conf

3 paste the below

options ath9k nohwcrypt=1

4. run modprobe

sudo modprobe -rfv ath9k
sudo modprobe -v ath9k

5. run the below command

sudo nano /etc/default/crda

REGDOMAIN=IN

*Note: im in India so i would preferably use IN, you should be using the country code you livein.... for country code, please check the below wiki page

https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

Save and exit. reboot your computer.

you may try this for other Qualcomm Atheros wireless cards aswell.it wont hurt as you can always delete the file in case it doesn't solve your problem.
