Hello.... I had an installer out to my house today to install a new HR44-500 with two wireless video bridge and two wireless clients. When my wife got home she was horrified (no joke) at the mess the tech left. He left all the coax cable from Spectrum in place and there was coax cable from when we previously had DTV. Anyway, me being me, I began to take out the old wire but it was so tangled that I disconnected the new installation as well. Now I'm having trouble getting it back together. I have a coax cable from the wall that is connected to a 4way splitter. The HR44-500 is connected to the splitter, the swm is connected to the splitter and video bridge is connected to the splitter. I'm left with one open connection, but I'm not able to figure out what went there. Also, do I need to connect a Ethernet cable to the receiver? Thanks for the help!
