We recently bought a new router, a Sitecom 300N, to replace a broken one. It worked for about a week but now the internet pretty much gone, I can rarely get a page to load.
I can ping the router's IP address fine. However if I try to ping a remote host, our default gateway, or the modem itself, and for all I get similar packet loss rates of about 70%. this suggests to me that the problem lies between the modem and the router. I've tried connecting a different router to the modem, but that works fine.
Any help?
