Hallo,
ich habe ein ASRock Q1900M und Lubuntu 18.04 64 bit. Daran habe ich ein größeres Update gemacht, nachdem ich die Installation länger nicht benutzt habe. Habe jetzt keine stabile Internetverbindung mehr.
Das scheint mir das gleiche Problem zu sein, das ich vor langer Zeit schon mal hatte. Damals wurde es nach einiger Forumsdiskussion gelöst, aber ich kann mich nicht mehr erinnern und finde den Forumthread nicht mehr (glaube, es war in einem anderen Forum).
Folgende Diagnose bisher:

Auffällig ist übrigens auch, dass das Netzwerksymbol (Verbindungsbalken) unten rechts in der Statusleiste doppelt erscheint. Das war damals auch schon so, als es zum ersten mal aufgetreten ist. Da vermute ich, dass irgendwas (Treiber oder so) zweimal gestartet wird, aber nur einmal sollte...
