XFiPods and Sonos compatibility

I installed one (of the 3 they force you to buy) XFi Pods to help my WiFi connections in one part of my house.  Now, in researching Sonos connectivity issues, I see that my phone is connected to the Pod along with one Sonos speaker, while the other Sonos speakers are connected to the Gateway.  And while this is supposed to be seamless, I can't get all the Sonos speakers to play the same music at the same time.  I didn't have this problem pre-Pods.  Is it possible to manually chose which connection a device uses (Gateway vs. Pod).  The Sonos forums mention problems with some mesh networks, but Xfinities weren't mentioned either way.  Thanks.
