  • 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 :)

    [  503.972087] usb 1-1.1: new high-speed USB device number 6 using ehci-pci

    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 :)
