Support XFINITY Internet Resetting Your Wireless Gateway


Internet issues? The first thing to try is resetting your wireless router, Wireless Gateway 1 (model numbers TG852G, TG862G, SMCD3GNV, TC8305C) or Wireless Gateway 2 (model number DPC3939). We’ll show you how.


Are you having problems accessing the Internet or connecting to your Wi-Fi network? These issues can often be solved by resetting your Wireless Gateway 1, Wireless Gateway 2 or wireless router. Like restarting your computer, resetting your router is a good first step in troubleshooting. If you’re ready to find out how to reset a wireless router, let’s get started.

Note: The following directions are for Wireless Gateway 1 and Wireless Gateway 2 users. If you have a different router, skip to the final section.

Normal Reset

Try a Normal Reset if you’re having trouble connecting to your network or accessing the Internet.

A Normal Reset reboots your Wireless Gateway 1 or Wireless Gateway 2, but maintains your personal settings, like your router name and password. Your XFINITY Internet and XFINITY Voice service will be unavailable for at least five minutes during the reset process.

For a Normal Reset, insert a thin object into the slot labeled Reset located on the rear panel. Press the button for two to five seconds and release to restart the gateway and perform a normal reset.

Warning: Do not press the button for more than 15 seconds, as this will perform a factory reset and restore all factory default settings. You’ll lose any settings you’ve customized, such as your Network Name (SSID), Network Password (Key), parental controls, firewall settings, etc.

To learn more about a factory reset, including other reset functions, see the Wireless Gateway User and Quick Start Guides.

Resetting Other Routers

Steps may vary for other routers and or non-Comcast gateways. If you don’t have a wireless gateway, here is a general set of instructions on how to reset a router. For specific directions, refer to your device’s documentation.

  1. Locate the Reset button, usually located at the back of your router.
  2. For routers with external Reset buttons, press and hold for about 10 seconds, or until the power light blinks.
  3. For routers without external Reset buttons, use a pointed, non-metallic object to press and hold the Restore Factory Settings button for about 20 seconds.
  4. Release the Reset button and wait for the router to reboot.
