Upgraded modem to T3200 + two boosters - can't connect my Sonos and Xbox One


Yesterday, I had my modem upgraded to the T3200 and had two wifi boosters installed. The wireless internet has been great around the house when accessed by computer or phone. However, I am unable to connect my Xbox One or my Sonos. They both see the network, but won't connect. I have tried restarting my modem as well as the hardware on each the Xbox and the Sonos. I have been unable to find anything online that might indicate how to resolve this issue.
