it's flashing on the internet light and nothing else.
This is a classic symptom for DCM425 modems. Two possible causes:
Either your cable has been disconnected..
In the home, outside the home, a squirrel bit through it or a Rogers technician cut the line. Etc.
Or your modem has a faulty capacitor near the flash chip..
Does your DCM425 have the Internet on/off button on it? If so, the bad cap is very likely. If you got the modem from Teksavvy or Canada Computers originally (no internet on/off button), this is probably not the problem.--
