Boost Pod not connecting to new gateway

I upgraded my Gateway today after having issues with my older one dropping out and needing a hard reboot once or twice a week. Since I did this my Xfi Boost-Pod is not visible in my App or able to be re-activated/connected to the new gateway. It will have a solid green light for about a minute after I unplug/re-plug it back in then goes to a slow white flashing light. It is a XE2-SG if that makes any difference with my new Gateway being the latest from Xfinity/Comcast.
