Netzwerkverbindung bricht ab ? Modem Router DGN1000v3

[syndrom]

Hallo

Bei meinen Modem Router bricht öfters die Netzwerkverbindung ab.

Bei meinem Modem ist sind die Lampen trotzdem alle grün.

Nach dem neustarten des Modem geht alles wieder.

Die neuste Firmware habe ich auch schon drauf aber trotzdem ist dieses Problem da.

Kennt einer das Problem ?
