There are a lot of suggestions in this thread regarding your Xfinity gateway (which is actually made by Arris):

The main one that is repeated--combos like the Arris are problematic and  you should replace it with your own separate, quality modem and router--is the best one.  However, there are a few other suggestions that involve keeping the Arris.  One is to have it put in bridge mode and use with your own router.  Another is to disable all parental control settings on the Arris and set it to trust the Xbox.  A third is to set the Arris wireless encryption to WPA2-PSK(AES) instead of AES/TKIP (never use TKIP, it is vulnerable anyway).  Try those and see the above thread for details.
