I just had a HR44 Genie install this morning but Whole Home DVR isn't working. I called DTV and had them activate the service, but I still can't add my client receiver. My system is only a HR44 with a HR22 as the client. I have ethernet hard wired to the back of the HR44 and that is working fine, but the HR44 isn't seeing the HR22 and there is no deca installed on the HR22. Shouldn't there be a DECA at the back of the HR22?
