A home network is a group of devices – such as computers, game systems, printers, and mobile devices – that connect to the Internet and each other. Home networks connect in two ways:
- A wired network, which connects devices like printers and scanners with cables
- A wireless network, which connects devices like tablets and e-readers without cables
Why Set Up a Home Network?
There are many reasons to establish a home network. Here are just a few of the things home networking allows you to do:
- Connect to the Internet from multiple computers, game systems, mobile devices, and more.
- Access files and folders on all devices connected to the network.
- Print from multiple computers on a single printer.
- Manage security settings for all networked devices in one place.
If you’re ready to try home networking, read below to find out what you’ll need to get started and to see the options available for your network.
What You Need to Set Up a Home Network
To set up home networking, you’ll need the following:
- XFINITY Internet Service subscription (or subscription to another Internet provider)
- A modem, which connects to the Internet, and a router, which connects your devices to each other and to the Internet through your modem (or a gateway, which functions as both a modem and a router)
- A computer or other device to connect to the network
The Wireless Gateway 1 (model numbers TG852G, TG862G, SMCD3GNV, TC8305C) and Wireless Gateway 2 (model number DPC3939) function as an all-in-one modem, router, and phone device. They automatically provide users with the best security settings available for a home network. Find out more about wireless gateways
Wireless Home Network
A wireless network, often called Wi-Fi, connects devices to each other and to the Internet without using cables. Read our rundown of wireless networking and its benefits.
Wired Home Network
A wired home network connects devices to each other and to the Internet using Ethernet cables.
There are several benefits to having a wired home network:
- Faster and more reliable connection to the Internet
- Increased security, as no outside users can access your network
- Easier set-up and troubleshooting than wireless connections
Mixed Home Network
Many people find that a mix of wireless and wired networking meets their needs best. For instance, devices that stream movies benefit from the quicker and more stable wired connection. Devices like laptops or tablets, however, benefit from the mobility available with a wireless connection.
Both the Wireless Gateway 1 and Wireless Gateway 2 come with wireless capability and four Ethernet ports, allowing you to connect devices with and without cables at the same time.
