It is compatible with some major internet providers like Xfinity, Cox, Spectrum, and many more.

This modem router is made to provide the fastest speed and highest coverage. It can deliver up to 6Gbps internet speed and give wireless range up to 3000 sq. ft.

How cool is that?

Moreover, it has one 2.5 Gigabit Ethernet port, 4 Gigabit Ethernet ports, one USB 3.0 port, and many more, connecting more than 30 devices like a computer, printer, gaming box, storage drive, etc.

Setting up this router is very easy as following the manual one can set it up easily, so there is no need to call anyone to set it up. Netgear (CAX80) supports both WEP and WPA/WPA2 wireless security protocols, so you do not have to worry about security.

The only flaws?

The Netgear (CAX80) is a little bit heavier and larger than other typical routers as it is a two-in-one unit. It is 12.6 x 10.2 x 5.2 inches and weighs 4.44 pounds.
