Habe vor Kurzem den Home-Ordner einer 16.04 LTS-Installation gesichert, die Festplatte gelöscht und eine Neuinstallation von 20.04 LTS durchgeführt und den Home-Ordner aus der Sicherung wiederhergestellt. Seitdem ist die WLAN-Verbindung zwar langsam und die Authentifizierung wird regelmäßig unterbrochen.
Ich habe versucht, dasDrahtloses Kernelmodul, wechselnWLAN-Energiespareinstellungen, UndDeaktivieren des N-Modus des Treibers, ohne Ergebnisse.
Ich glaube, ich muss entweder die WLAN-Treiber neu kompilieren oder die Kernel-Version anpassen, aber ich bin mir nicht sicher, was ich tun soll, und ich würde den Kernel lieber nicht anfassen, wenn es nicht unbedingt sein muss. Kann mir jemand einen Hinweis geben, was davon wahrscheinlich das Problem ist?
