RAM

that's a good idea - it certainly would have saved me from a lot of work :)

thanks for the answer :)

I just tried to remove and insert the wifi adapter, and now the dmesg has a message about loading a driver :)

for some reason, it loads the old driver still. rtw_8821cu instead of rtw_8821au. I'm a tad confused, but I'm happy it's working :)

thanks a lot for the help :)

it does not show up from ip link show.

what does it mean, that it is not initialised ?

//EDIT:

I ran a script called remove-driver.sh from the driver that I used to use (https://github.com/morrownr/8821cu-20210916) and now the wifi adapter is up and running again :)

Thanks a lot for the help - I'm not really sure, what was wrong, but I'm very thankful for the help :)

Was the problem, that I had a bad driver installed ?

dmesg gives me 942 lines - is there anything specific I should be looking for or share here ?

sad to see that he thinks like that about rape and the whole Epstein thing :(

Just as I was looking for a new notes app - it is perfect 😍

A world without borders sounds like a dream 😍
