Ich musste den Treiber installieren prohttps://github.com/tomaspinho/rtl8821ceein paar Mal auf einem ASUS-Laptop und jedes Mal funktioniert es eine Weile, bevor es kaputt geht. Ich habe mir Dutzende von „Lösungen“ angeschaut, obwohl keine das Problem wirklich dauerhaft gelöst hat (d. h. ich muss den Treiber nach einer Weile deinstallieren/neu installieren). Jetzt kann ich mein WLAN jedoch ohne einen USB-Dongle überhaupt nicht zum Laufen bringen.
ProRTL8821CE-Treiber installiert, aber nicht aktiv, @heynnema, bat darum, Folgendes mitzuteilen, um die Suche nach einer Lösung zu erleichtern:

Antwort1
Ich musste den Treiber mit einem anderen WLAN-USB-Adapter neu installieren
Von mir verwendete Befehle:
sudo aptitude reinstall rtl8821ce-dkms
sudo modprobe rtl8821ce
dann habe ich den USB-Adapter entsorgt und RTL funktionierte wieder
PS: das passiert in Ubuntu 22.04LTS... schon wieder!
