Hi, I would like to upgrade my modem

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

Hi there, @user_sxnjdc! Thanks for reaching out to us here on the Community Forum. The quickest way to get a new modem is to bring your current one and power cord to your local XFINITY Store for an exchange. You can find hours and locations here : https://www.xfinity.com/local/store-offers 

Details about the XB8 can be found here : https://www.xfinity.com/support/articles/broadband-gateways-userguides

A quick overview is this is that it features WiFi 6E and can handle more devices at once and has more bandwith for even more reliable connections. 

If you have any specific questions, we would be more than happy to answer!
