Told to upgrade modem with Cox.
Do I need to or should I purchase a modem/router unit or just the new 3.0 modem and continue to use my current router?
Thanks
It is up to you. Your old router will continue to work with just a DOCSIS 3.0 Modem. The benefit here is that it is all in one package. If I personally already have a router, I would just simply continue using that.
