That isn't a model. Maybe you mean the R6020? if so, its way past time to upgrade that router.

In the mean time, the CM2500 has 2x ethernet ports but only 1 can be used at once for most ISPs. If you have anything else connected to it, shut both the modem and router down. Disconnect all ethernet from the cm2500. Then power it on, give it 3-5 minutes, and then power on the router. give it a couple minutes. Don't connect anything else to the modem.
