No landline connection/modem light
I just replaced my modem (which had phone ports) with a new one, and I can't get the modem to recognize the phone, which worked fine with the old unit. No panel light, no dial tone, no service. Have restarted the modem 4X now, still no dice. Any way to fix this, or do I need to find the magical customer service number and speak with a human? Current router is a Cisco DPC3941T.
