Best Wifi Cable Modem for Xfinity – The newest Xfinity modem is the xFi Gateway 3rd Generation. It supports internet speeds around 700 Mbps—less than the xFi Advanced Gateway’s 1,200 Mbps.
Xfinity’s big selling point for the 3rd Generation is that it’s light gray instead of black (no, we’re not joking—Xfinity’s support article points out the color first). It also has four Gigabit Ethernet Ports to the xFi Advanced Gateway’s two.
Otherwise, we can’t see anything special about it that differentiates the 3rd Generation from Xfinity’s xFi Advanced Gateway. Newer isn’t always better, it seems.

If you take the excellent Netgear C3000 Cable Modem Routerand replace its router with the impressive Netgear N600 Wireless Dual Band Gigabit Router (WNDR3700), you get Netgear’s C3700 Cable Modem Router . Generally, I recommend going with a dedicated wireless router even when using a modem/router combo, but the C3700 is the lone exception.
This is the only combo modem and router I’ve tested that could make adding a dedicated wireless router unnecessary for all homes, save for those with heavy video-streaming, gaming, or advanced Wi-Fi needs.
