I have an HR22 that died and Directv is sending an HR24 to replace it. I need help understanding how to connect an HR24 that will be replacing the HR22. What I need help with is understanding the Deca connections since HR24 has built in Deca while the HR22 being replaced does not. I have whole home with the HR22 and an HR44. There is a white Deca adapter connected to the receiver with both a coax and an ethernet cable and there is a black Deca adapter (CCK?) connected to the router by ethernet. I'd like to confirm that I need to leave the CCK connected as is but that I need to eliminate the DECA adapter and just connect by coax to the HR24.
