Guten Tag,
Wir haben seit ein paar Tagen Probleme mit unserem Internetanschluss (22395 Hamburg) wir haben ein eigenes TC4400 Modem mit einer Opnsense Firewall im Einsatz. (Fritzbox etc hat für uns zu wenig Funktionen)
Dort Internetverbindung bricht zwischendrin immer wieder zusammen. . Ich erhalte dann über die Firewall keine WAN IP mehr. Nach einem Modem Neustart ist es meistens behoben.
Die Firmware auf dem TC4400 (70.12.41-180903) soll ein paar Probleme mit OFDM/OFDMA haben. Bevor wir das Modem jetzt einschicken, wüsste ich gerne ob es bei uns in dieser Richtung eine Änderung gab, oder ob ein anderes Problem vorliegt.
Das Modem hat folgende log Einträge:
