Internet abbruch

Hallo, seit der neuinstalation von suse 9.1 bricht die internet verbindung immer nach einiger Zeit ab!
Kinternet gibt folgendes Protokol aus:

Was kann das sein?

Du solltest mal hier rein schaun:

[Tip] Links zum Thema MTU und Internetverbindungsprobleme
http://www.linux-club.de/viewtopic.php?t=15947

Hat leider nichts gebracht!
Sonst noch eine idee?

Kann mir keiner Helfen?
Das Internet wird immer noch abgebrochen!
Gibt es irgendwo eine Log Datei oder sowas was uns weiter bringen könnte?

Poste hier mal zwei Ausgaben:
