Make sure you have the equipment you need to enjoy the benefits of wireless networking in your home.
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. Find out more about wireless home networking.
A modem is a device that connects to the internet with a coaxial cable, the same cable that provides TV service to your cable box.
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 the DOCSIS Device Information Center. Select your level of service (found on your billing statement) to see a list of modems that will work for your network.
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.
Note: To create a wireless home network, you’ll need both a router and a modem, or a gateway that functions as both (see below).
The following routers are Comcast-approved:
- Netgear WNR1000 (Wireless-N)
- Netgear WNR 3500 (Wireless-N)
- Linksys WRT310N (Wireless-N)
- Netgear WGR614v8 (Wireless-G)
The following routers are Comcast-approved, but are older models with limited support:
- Netgear CG814v1 (Wireless-G)
- Netgear CG814v2 (Wireless-G)
- Linksys WCG200v1 (Wireless-G)
- Linksys WCG200v2 (Wireless-G)
- Linksys BEFCMUH4 (Wireless-G)
A gateway is a device that functions as both a modem and a router, which means you only need one device to set up your wireless home network. The Comcast-provided Wireless Gateway 1 (Model Numbers TG852G, TG862G, SMCD3DNV, TC8305C) or Wireless Gateway 2 (Model Number DPC3939) also provides voice service and four ports for wired connection to your network.
Both the Wireless Gateway 1 and Wireless Gateway 2 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. Find out more about wireless gateways.
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.

A WiFi device is any device that can connect to a wireless network. This includes computers, laptops, game systems, printers, tablets, and mobile devices.
