Hallo zusammen, auf meinem neuen HP Laptop I5-db0500ng mit wlankarte Realtek 8821ce habe ich Lubuntu 18.04 installiert. Rechner läuft und Wlankarte verbindet sich mit dem Router. Wenn ich ein anderes Wlan Netz auswähle dauert es endlos und es kommt keine Verbindung zustande. Im Moment helfe ich mir damit die bestehende Wlan Verbindung zu trennen dann das Funknetzwerk zu deaktivieren, danach wieder aktivieren und das andere Wlan Netz anzuwählen. Etwas umständlich auf Dauer. Woran kann das liegen ? Neuestes Treibermodul ist installiert. Gruß Peter

Kennst du die Hinweise?

ja danke, nach der Anleitung habe ich das neueste Modul gebaut. Geht aber trotzdem nicht.....

H, wie hast du installiert? Die aktuellste Variante ist die hier

https://forum.ubuntuusers.de/topic/wlan-modul-nicht-aktieviert-unter-ubuntu-18-04/#post-8985121

Den anderen zuerst deinstallieren!

Ja, danach habe ich installiert.

Deinstalliere den, deaktiviere SecureBoot zuerst und installiere ihn erneut

Secure Boot war aus. Nach erneutem installieren kommt die Meldung dass dieser schon installiert ist....

Zeige alle Terminal-Ausgaben von hier in Codeblöcken zur "Diagnose".

Gruss

Das Netzwerk "NB-PH" wird gar nicht angezeigt.

ja, bin jetzt in einem anderen Netz. Aber das ist auch egal, es funktioniert nicht richtig, egal in welchem Netz. Gruß Peter

Ok, dann

sudo sed -i "s/wifi.powersave = 3/wifi.powersave = 2/g" /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
sudo systemctl restart network-manager.service

Keine Veränderung. Auch herunterfahren und neu starten ändert nichts.
