Wifi not working in the system - AR9845, debian

[TestikCZ]

I’m having an issue with the functionality of WiFi in the system itself (GUI). I’ve tried both the Gnome and KDE Plasma environments. I’m experiencing problems connecting to a password-protected network. The dialog for entering the password keeps appearing. If the network is unsecured, it connects without any issues. However, during the Debian installation, there was no problem connecting—I was able to connect to WiFi normally.


My WiFi card is an AR9845, and it's an older laptop. I also tried connecting via a USB WiFi adapter, and that works perfectly fine, even on secured networks. The USB adapter is actually older than the internal WiFi card – it's an Asustek WL-167g USB WLAN adapter.

I am newbie to Linux, a windows user.

Hi and welcome to the forums.

You can try running the following commands:

lsmod | grep ath9k

Does it list anything?

If not run:

sudo modprobe ath9k

Does it result in error?

Then again run:

lsmod | grep ath9k

Does it list this time?
If yes try connecting to wifi.

edit:

The dialog for entering the password keeps appearing

Please share output of:

setxkbmap -print
echo $XDG_SESSION_TYPE

Atheros [now Qualcomm] should run ok with the ath9k Linux kernel driver

You're using US keyboard layout, note that if that's not your native keyboard layout then wifi password may not work if you type it in your native language.

This could be another reason why password box keeps appearing, try to switch to X11 desktop session and try again.

To switch to X11, log out and then on login screen somewhere should be drop down option to change from wayland to X11, then login with your password.

Used password does not contain czech characters, also always check it if it match. Tried to switch to CZ keyboard layout and it does not help.

i have found only gnome xorg, but it does not help.

@TestikCZ
Your other output looks OK I see no issues and your wifi card model is supported by ath9k driver.

Have you tried running sudo modprobe ath9k and then trying again?

 

[TestikCZ]

Tried without success.
Also tried linux mint live usb with same results - not working.
Its strange.

It could be problem with your router, try restarting it or resetting.
