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.
