When they installed DirecTV, the installer put in a DCA2SR0-01, "Connected home adapter". It plugged in to my router and then went in to the coax system. I had a lightning strike that damaged some network stuff. The on-demand features of the HR34 box I had stopped worked, and when I went to Network settings it said it wasn't connected to the internet. So I figured this adapter was damaged. So I took out the adapter and put ethernet in to HR34, and everything worked fine. The reason I am asking is because I had run an ethernet line to where the HR34 is prior to DirecTV coming out, because I figued the box would need it (or could use it). But the installed decided to install this "Connected Home Adapter". Why do that if I had run the ethernet? WIth the connected home adapter out, my HR34 and 2 x H25 still all seem to work fine. Any tips on why install it in the first place?
