Interested in setting up a wireless network in your home? You'll be able to keep your laptop, tablet, e-reader and other WiFi devices connected to the internet from anywhere within the WiFi signal range.
With wireless networking, you can download photos, stream videos and even print documents from every room in your house. There's so much you can do with WiFi, but you have to make sure you have the right home networking equipment first.
Here's a list of the networking equipment you need to connect your computers, tablets, game systems, and more to the internet and to each other. Learn more about setting up your wireless gateway and connecting to your wireless network.
Wireless gateway/cable modem router
A wireless gateway (also known as a cable modem and WiFi router) is a device that functions as both a modem and a router, which means you need only one device to set up your wireless home network. You can find a list of Comcast-approved wireless gateways that match your level of service at My Device Info. Select your level of service (found on your billing statement) and filter by "Built-in WiFi" to see a list of wireless gateways that will work for your network. Learn how to find the right device using My Device Info.
The Comcast-provided Wireless Gateway 1 (Model Numbers TG852G, TG862G, SMCD3DNV, TC8305C), Wireless Gateway 2 (Model Numbers DPC3939, TC8706C) and Wireless Gateway 3 (Model Numbers DPC3941T, TC8717, TG1682G) also provide Xfinity Voice service and have four ports for wired connection to your network. These gateways support all residential Xfinity Internet service tiers through Extreme 105. They also come equipped with preset features that help you set up your wireless network in a quick and secure way. Learn more about wireless gateways from Comcast.
Modem
A modem is a device that connects to the internet with a coaxial cable, the same cable that provides TV service to your TV Box. If you choose to use a modem, you will also need to use a router to complete your wireless network.
To see if you have a Comcast-approved modem, or to find out which modem is right for your level of internet service, look for its name at My Device Info. Select your level of service (found on your billing statement) to see a list of modems that will work for your network.
Router
A router is a wireless capable device that transmits a wireless signal. Wireless devices, such as laptops and tablets, use this signal to connect to each other and the internet through a modem.
Wireless routers typically support one of two wireless standards, Wireless-G or Wireless-N. Wireless-N is newer and Comcast recommends that users with Blast! or Extreme Xfinity Internet service upgrade to a Wireless-N router. While you can access the internet with all routers regardless of your speed tier, a Wireless-G router may prevent you from getting the maximum possible speeds.
Wireless adapter
A wireless adapter is a device that enables computers or laptops without wireless capability to connect to a wireless network. Generally, wireless adapters are available in USB or card formats.
WiFi device
A WiFi device is any device that can connect to a wireless network. This includes computers, laptops, game systems, printers, tablets, and mobile devices.
You may need a WiFi device, such as a computer or laptop, if you want to change your wireless home network settings. Learn more about WiFi.
