Ich habe leider seit gestern morgen folgende Probleme mit meinem Glasfaseranschluss: Der Router bekommt per pppoe nur für kurze Zeiträume eine IP. Die meiste Zeit gibt es keine. Wenn eine IP da ist, dann ist die Internetverbindung tadellos. Das gilt dann aber nur für kurze Zeit.

Mein Setup ist folgendermaßen: Ich habe ein Glasfaser Modem 2 von der Telekom und dahinter meine eigene ubiquiti Infrastruktur. Der Router ist eine USG-4 Pro. Letzterer hat die nötige pppoe Konfiguration und monatelang lief alles gut. Ich habe auch seit Monaten nichts geändert.
Ich habe mir mal die UI des Modems angeschaut, da wird auch eine grünes Häkchen angezeigt, wenn der Router gerade keine IP bekommt. Ich hab alle Geräte mal neugestartet und bei dem Modem sogar mal einen 10s reset gemacht. Das änderte jedoch nichts.

Die pppoe logs auf dem Router sehen so aus:

Jetzt weiß ich nicht wie ich das ganze weiter untersuchen kann, bzw was sinnvolle nächste Schritte wären, um das Problem zu lösen. Bei der Störungsmeldung per Telefon weiß ich nicht so genau was ich sagen soll, um das Problem zu beschreiben. Ich bin ja noch nicht einmal sicher, ob das Problem auf jeden Fall auf eine Störung hindeutet. Ich vermute es schon, da ja nix anders ist im Setup als vorher und es sogar anfing während wir im Urlaub waren.

Danke für Eure Hilfe
