NETGEAR CM3000 Reviews

Perfect. Exactly what I wanted

I bought this because AI recommended it. I specifically didn’t buy it from Amazon because they don’t know how to ship electronics correctly and B and H does! Came perfectly intact and install was super simple and easy. My speeds now go over what I pay for, 1gbps even on wifi. I went with a Ubiquiti Dream Router 7 for WiFi and it is also perfect for my small house.

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.
