Netgear Nighthawk CM3000 modem

So far the modem has worked as I would expect. It's only been a week but pairing it with the new router is providing faster speeds and more connection consistency. I would recommend this modem if you have Xfinity internet.

Awesome Modem!!!

Does this have Wi-fi 6?

Asked by: Paul

The Netgear Nighthawk CM3000 2.5G DOCSIS 3.1 Cable Modem does not have Wi-Fi of any kind, because it is a modem and not a router. It must be used in conjunction with a wireless router if you want to create a wireless network.
