Probleme mit der DNS-Konfiguration

Hallo,

wir haben in unserem Haushalt einen Router von T-Online und zwar den Speedport W 503V. Es laufen 3 Rechner über diesen Router, 2 mit Lan und einer mit Wlan, außerdem bekommen wir auch Fernsehen über das Internet. In letzter Zeit funktioniert das Internet für paar Minuten nicht mehr danach geht es wieder, wenn ich dann die Vista Problemsuche starte kommt immer die Meldung “Möglicherweise liegt ein Problem in DNS-Konfiguration (Domänenserver) vor”. Meine Frage ist jetzt wie kann ich das Internet wieder einwandfrei zum laufen bringen?

hier ist ein Auszug aus aus meiner ipconfig:
