Ich habe das selbe problem (68159 PLZ) habe allerdings noch keine Antwort von Kabel BW bekommen
Der Router scheidet als Fehlerquelle aus da auch ohne Router mit PC direkt angeschlossen das Problem besteht.
Was abhilfe schafft ist es das Modem 1-5x neu zu starten...
*edit*
Entweder steht der Router bei "DOCSIS Downstream Channel Acquisition" oder er geht bis "Establish IP Connectivity using DHCP"
und bricht dann wieder ab. Da der Router seine Zeit bei einem Hardreset (Stromkabel ziehen) verliert
sieht mein Log natürlich
Super aus:
