I’m crowd sourcing this among the three or four people who read this blog. And it might help someone who’s experiencing similar symptoms.
If you’re experiencing intermittent disconnects between your modem and router, it may be a problem with your incoming signal.
It makes no sense to me either, but when my cable modem loses the signal from my provider it disconnects the router. The router’s status changes from “connected” to “connecting”, and of course the modem’s status page is inaccessible from wireless network. What I thought was a problem between the modem and router was actually caused by a poor signal from the provider. It’s a Motorola Surfboard and a Medialink router, but this also happened with a Cisco modem which the cable company replaced and old Cradlepoint modem.
Any ideas why this might happen?
