Support XFINITY Internet Resetting Your Wireless Gateway


Are you having Internet issues? Try resetting your wireless router, Wireless Gateway 1 (models TG852G, TG862G, SMCD3GNV and TC8305C), Wireless Gateway 2 (model DPC3939) or Wireless Gateway 3 (models DPC3941T and TC8717).

Note: Wireless Gateway 3 is only available in select markets at this time.


Are you having trouble accessing the Internet or connecting to your in-home XFINITY network? These issues can often be resolved by resetting your wireless gateway or wireless router. Similar to restarting your computer, resetting your router is typically the first step in troubleshooting.

Note: The following directions are for wireless gateway users. If you have a different router, please skip to the Resetting Other Routers 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, but maintains your personal settings, such as your router name and password. Your XFINITY Internet and/or 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 back panel. Press the button for two to five seconds and release to restart the device.

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 will lose any settings you have customized, including your WiFi Network Name (SSID), WiFi Network Password (Key), Parental Controls, firewall settings, etc.

To learn more about the factory reset, please see Wireless Gateway Guides.

Resetting Other Routers

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

  1. Locate the Reset button, which is usually located on the back of the 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 at least 20 seconds.
  4. Release the Reset button and wait for the router to reboot.
