Modem and/or Router No Longer Functioning...Help Please

post #1 of 4
Thread Starter 
At home I have Charter Communication providing the connection to my RCA DCM425 which then runs into a Cisco E4200. All has been fine for months.

Last night there was a power outage at the apartment followed by 10-15 minutes of a soft reset on the modem which got things running again.

Two hours later the internet cut out again...no number of hard or soft resets on the modem fixed anything. I unplugged it all to see what happened after letting the hardware "rest" for a few hours.

This morning I plugged things back in, and still nothing. I am able to connect to the E4200 router just fine. I am able to get internet access by connecting directly to the modem via an ethernet cable fine.

The modem and router in conjunction get me nowhere though.

Any idea what's going on? Do I need to be buying a new modem...new router...both?

You could try MAC cloning the WAN interface on the router from your PC's NIC that worked directly to alleviate any potential DHCP allocation lease conflicts but it's likely just shot.

Just an idea, but perhaps the ethernet port on the router that provides service from a modem is fried. It sounds like other than that port it works fine, but since it is that port you can't really use the router. Do you perhaps have another router or could borrow from a friend just to check that? Maybe you could use one of those ethernet jack continuity checkers.
