Ich verwende Ubuntu 20.04.1 auf einem ThinkPad T400. Jedes Mal, wenn ich den Computer starte und er versucht, eine Verbindung zu meinem Router (AVM FRITZ!Box 7490) herzustellen, wird die Verbindungschlägt fehlmehrfach zum Aufbau. Nach ca. zwei Minuten ist die Verbindung aufgebaut. Hier der Auszug aus dem Syslog.
