Here's the situation. I am upgrading from an HR21-700 with Whole Home to a Genie. At the start of this, here was my HR21 configuration: two wall coax ports; one going into a black box with power labelled SWM ODU Only, with a cable coming out of it going to a splitter. Out of one side of the splitter goes a cable to a band stop filter that then connects to coax in 2 on the back of the HR 21. The second line coming out of the splitter goes to a box labelled DCA/connected home adapter. Coax comes out of the other side of it, which plugs into HR21 coax in 1, and also an Ethernet cable comes out of the DCA box and goes into the Ethernet port on the HR21. Now back to the wall's second coax port: it goes into another box labelled DECA broadband adapter. It also has power going into it, and has an Ethernet cable coming out of it going into my router. Almost forgot, HR21 has HDMI out to my receiver. How should I hook up the Genie?
