Ich verwende Ubuntu Desktop 19.10 und verwende es hauptsächlich als Server. In regelmäßigen Abständen (alle paar Tage) wird die WLAN-Verbindung unterbrochen und die Verbindung wird nicht wiederhergestellt. Ein Neustart des WLAN-AP hilft nicht. Nur manuelles Wiederverbinden/Anhalten und Fortsetzen/Neustarten des Ubuntu funktioniert.
Kein anderes Gerät in meinem Haus hat das gleiche Problem. Wie behebe ich das Problem, sodass es sich automatisch wieder verbindet?
Folgendes steht in meinem Tagebuch, wenn das WLAN ausfällt:
