WiFi stopped working, suggestions?

[pjsf]

Code:

sudo inxi -n

I've also set the country code successfully, but it makes no real difference.

Maybe an HW (power) issue, but from the output it's recognized correctly but seems soft blocked!?
You probably know that already, but I would recommend the following:

Code:

sudo rfkill list

If it shows "soft blocked yes", you can unblock with

Code:

sudo rfkill unblock 0

I would also recommend to (once again) set the correct country code with:

Code:

#Change "XX" to your country code, e.g. "DE" for Germany
sudo iw reg set XX

Make it permanent in the crda file (REGDOMAIN=XX) in

Code:

sudo nano /etc/default/crda

Thanks, but I've already tried all of those. rfkill shows soft and hard unblocked for both. and setting correct crda domain made no difference.
