What Modem Is Best For XFINITY?
The XFINITY modem that you need for your individual XFINITY service depends on three factors. First, your Internet speed. If you are unsure what your subscribed speed is, you will find it on your bill. Modems are all built to handle many different speeds, so this is very helpful. Secondly, the right modem for you depends on your other XFINITY services. Do you have home phone service with Comcast? If so, then you will need an eMTA unit, a.k.a. voice modem built exclusively for XFINITY voice and internet.
Last but not least, would you prefer an XFINITY modem with built-in WiFi, or would you like a modem and separate router? How big is your home? With that said, you can see that not everyone can use the same XFINITY modem. Therefore, you should not rush into buying just any modem because it may not work for your services. There are many factors that decide for you, which modem you need.

XFINITY WiFi Router, a.k.a. Gateways
XFINITY gateways, most often referred to as a modem router combo, have a built-in router. Therefore, you will not need a separate router. The advantages of a gateway are that they are easier to set up, take up less space, and not so many messy wires.
XFINITY DOCSIS 3.1 Gigabit Modems
All of these modems are DOCSIS 3.1. Some have WiFi capabilities and others do not. The same goes for voice capabilities. All current 3.1 modems are backward compatible with 3.0.
Comcast Voice Modems
Voice modems, a.k.a eMTA, are needed if you have XFINITY home phone service, not mobile service. If you have Double Play or Triple Play, chances are you are paying for this service, especially if you have the Triple Play package.
Comcast is the largest cable Internet provider in the USA. The Comcast Corp. has service available in 40 States.
