Folgendes Problem: Es hängt ein Linksys WRT54GL mit DD-Wrt dran. Nach einiger Zeit, manchmal nach 10 Minuten, manchmal erst nach über einem Tag ist die Internetverbindung weg. Also dann einloggen ins Router Interface und nachsehen. Sieht aber alles in Ordnung aus, IP (über DHCP) is da, Gateway und Subnet sind auch vorhanden. Das seltsame ist jedoch, wenn ich auf "DHCP renew" klicke funktioniert das Internet wieder in 95% der Fälle. Manchmal hilft nur Modem Neustart.

Noch zusätzliche Infos: Fernsehen funktioniert einwandfrei. Bei dem Arris Modem handelt es sich um die Version mit den 2 Telefon Buchsen.
Weiß vielleicht jemand was da sein könnte?
