Best Cable Modem Router Combo for Xfinity

Best Cable Modem Router Combo for Xfinity – In other words, your modem can work with only one device, while the router will act as a dispatcher between the modem and other internet-capable devices like your TV, smartphone, printers, and much more.

Most homes or offices are used to getting the router and modems as separate devices. Though they may have reasons for that, getting a 2-in-1 device is ideal. Aside from the convenience it gives, you will love many other features that are discussed below.

A modem-router combo is often called a Gateway, and most ISPs on sign up give you the option to rent one at a low monthly fee. Xfinity, for example, gives you a $14/mo combo option; at first look, this may seem cheap, but when you punch it into your calculator, you’ll discover that in a year, you are paying almost double of what it will cost you if you purchase your modem-router combo.
