Variation on a theme: For internet connection: Instead of connecting the DECA module to the switch, my installer connected from the DECA module to the HR-22 (both coax and ethernet port 1). He then ran an ethernet cable from port 2 of the HR22 to the switch. I questioned this but he said it would work, and IT DOES!! This eliminated the need for yet another dongle and power inserter behind the a/v cabinet. I will post this as a separate thread for others' information.
