Having issues - Upgraded to X1 dvr with 3 XiD-P small boxes

Upgraded to X1 dvr with 3 XiD-P small boxes from old style standalone dvr's (which all worked but one started having problems). The main X1 box works fine regardless of where I connect it but the XiD-P boxes will receive only basic channels and can't receive a refresh signal or be seen by customer support. Do these satellite boxes communicate via the internet? I have my own modem and router and do not see an option on the X1 main box to sign in to the wifi. Have not tried connecting via ethernet yet. Any help/info would be appreciated. Thanks
