Why doesn't my router work with my Spectrum modem?

Episode 1367 (1:53:29)

Marcello from Northridge, CA
Arris Surfboard 6183

Marcello has noticed since Spectrum bought TIme Warner, he has trouble connecting to the internet. They disconnected his router and it works, though. What happened? Leo says that when Spectrum took over, they probably enabled the router side of his modem and that put it in conflict with his router.

Leo recommends that he find out what third party cable modem they support and buy one. DOCSIS 3 is what he'll be looking for, and it will come with the benefit of making his internet cost less since he's not paying a $10 modem rental. Leo uses the Arris Surfboard 6183.
