I need to build or buy a relay that runs a cycle of closed for one hour and open for ~1.5 seconds over and over again.

I have an cable internet service proivder that cuts me off every hour when I am downloading at full bandwidth. It has nothing to due with my dchp lease, I have already checked that. The only way to get back on the internet is turn my modem on and off (my is working just fine also).

The modem uses a 12v dc 1amp power suppy. I was thinking I could cut one of the two wires, that run from the trasfomer to the modem, and attach a always closed relay. Then send a 12v pulse to the coil of the relay once every hour for about a 1.5 seconds, opening the relay, turning my modem off then back on.

Is their a better way? mabye use a flasher to the relay? How can I build what I need?

I know it's an off the wall thing but I would really like any help you guys could give. Thanks,

Joe
