Thanks for your detective work. The modem is set to bridge (I'm pretty sure), and the router is set on PPoE. However, you have given me some new material to investigate. Could the modem be the one causing the disconnect/re-connect loops. When I bought the modem, I am pretty sure I set it to bridge talking to it directly attached to a pc. Then I installed the modem, and I don't know how to query this modem now through the router to display its settings. Is there a way to do this, or do I need to connect the modem directly to a pc to query its settings again? Al
