Know More About Wireless Home Networking Equipment List

Make sure you have the equipment you need to enjoy the benefits of wireless networking in your home.
Overview

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. See Set Up Your Wireless Gateway and Connect Your Wireless Network for more information.
Modem

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.
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.

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 wireless 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 provide XFINITY Voice service and have 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. See What is a Wireless Gateway from Comcast? for more information.
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.

To find out if your computer needs a wireless adapter, follow these steps.

Windows
Click the start menu or right-click the My Computer icon and select Manage.
Select Device Manager.
Windows – Device Manager
Click + next to Network Adapters.
Windows – Device Manager – Network Adapters
If any adapter says Wireless, your computer supports wireless networking.
Mac OS
Click the Apple in the upper left-hand corner of your screen and select System Preferences.
Select Network.
Mac OS X – System Preferences
If Airport is listed, your computer supports wireless networking.
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.

Tips To Optimize Your Internet Speed

Learn about some key ways to understand your current XFINITY Internet speed and how to improve it.
General Speed Tips

Your XFINITY Internet equipment (wireless gateway, modem or router) and connected devices (computer, laptop, smartphone, tablet, etc.) can all affect the Internet speed you experience.
The first step to optimizing your Internet speed is to know what your current download and upload speeds are when you’re connected to your in-home network. You can do this by taking XFINITY’s Speed Test; the results will be best when connected via Ethernet.
Next, you can check what speed plan is on your XFINITY account using My Account.
Then, confirm that your Internet equipment (wireless gateway, modem or router) is compatible with your speed by visiting MyDeviceInfo.
Once you’ve determined that your equipment is a good match for your speed plan, make sure your computer or laptop’s hardware and software are able to support your speed. For more details, see our XFINITY Internet Minimum System Recommendations.
WiFi Speed Tips

In addition to your equipment’s compatibility with your Internet speed and connected devices’ capability to support that speed, be sure to set up your equipment and devices for success to get the most out of your wireless Internet connection. You’ll want to do the following:

– Make sure you’ve positioned your wireless gateway or router in the most ideal location within your home.
– Be in close proximity to your wireless gateway or router when connecting to WiFi.
– Verify you’re connected to the right WiFi network, which is your private, in-home network.
– Confirm when it makes sense to connect wirelessly or use a wired connection, as some activities can be done quicker via Ethernet (e.g., online gaming and video streaming).
– Use newer generation devices (e.g., late model smartphones and tablets) when connecting over WiFi, as older devices will not be able to achieve the fastest-possible speeds.

Upgrade Your Wireless Network Equipment

Get the most from your wireless home network by upgrading your equipment and updating firmware.
Overview

Because outdated equipment and firmware can slow down what would otherwise be a fast connection, you’ll want to make sure your network setup is always up-to-date to get the most out of your XFINITY Internet service.

Like computers and mobile devices, new WiFi equipment models are released regularly. While you don’t need to immediately update your equipment to keep your home network running, you could be missing out on improved services if you continue to use older models. As a result, be sure to check MyDeviceInfo to find out if your equipment (wireless gateway, modem or router) is compatible with your Internet speed.
Firmware

Firmware is a program or set of instructions that controls hardware like a router or modem. Manufacturers periodically update their firmware. Depending on the WiFi equipment that you have, you may want to check the Internet for firmware updates to make sure you’re still getting the best performance out of your equipment.
Using a Wireless Gateway

One advantage to leasing a wireless gateway from XFINITY is that we regularly update our firmware automatically, so you don’t have to check for new updates. To learn about the different wireless gateways offered by XFINITY, see Wireless Gateway 1, Wireless Gateway 2 and Wireless Gateway 3 Feature Comparison.
Using a Modem and Router

If you don’t have a wireless gateway from XFINITY, you’ll need to periodically check for updates. Generally, you can check for these updates through your router’s administration site. For specific instructions, please see your router’s user guide.
