Final answer:
If your new Gateway is not an xFi Gateway from Comcast, your xFi Pods will not work because they are designed to work specifically with Comcast's xFi Gateways. You can contact Comcast's customer service for potential buyback or recycling options, or sell or give the Pods away.
Step-by-step explanation:
If you purchased xFi Pods through Comcast when you had a leased Gateway, and now you have your own Gateway, the xFi Pods may not be compatible with your new equipment. The xFi Pods are designed specifically to work with Comcast's xFi Gateways. If your new Gateway is not an xFi Gateway from Comcast, the Pods will not work as they rely on software that is unique to Comcast's xFi Gateway. In this situation, you could consider checking with Comcast's customer service to see if there is a buyback or recycling program. Alternatively, you may consider selling or giving them away. If you do replace your new gateway with an xFi-compatible gateway in the future, you could reuse the xFi Pods at that time.
