Hallo, ich habe einen HP Laptop Model 15-db0025no mit einer eingebauten Realtek RTL8821CE. Ich habe einen, ohne über Konsequenzen nachzudenken, Update auf 19.10 (von 19.04) gemach. Jetzt läuft das WLAN, das auch schon nicht von sich lief, überhaupt nicht. Folgendes musste man jedesmal mit den Treibern machen, wenn das WLAN aussetzte:
sudo make clean sudo make all -j4 sudo make install sudo modprobe -a 8821ce
Das geht nun nicht, und das Wlan bleibt stumm. Kabelverbindung funktioniert aber. Kann ich das irgendwie geradebiegen oder hilft da nur ein downgrade? Vielen dank!
