Activating Your Wireless Gateway

Once you've installed your wireless gateway device and established a temporary Internet connection, you're ready to activate your XFINITY Internet/Voice service. See information about preparing to activate your wireless gateway.

This article outlines the on-screen instructions to complete the activation of your gateway.

Note: If you have an Arris 1682G wireless gateway, see the TG1682G activation instructions. To determine the type of gateway you have, check the make and model information located on the bottom of your device. You can also check this information in My Account.
