I had the install yesterday but the tech did not hook up the internet deca to the router. When he left everything seemed to be working fine. He came back today and did the internet part but now the HR20-700 will not find a signal. What is strange is that without the deca hooked up and the sat line going straight into sat1 I get the signal. He swapped deca's thinking that may be the issue, but it did not help. Anyone else with a HR20-700 seeing problems, and it is strange how the problem started when he hooked the deca to the router. Also without DECA hooked up I get a signal, however some HD channels glitch alot. I also tried hooking the cat6 cable I was using before into the ethernet port and I was able to use MRV without the DECA, but being hooked up the old way on just the one receiver. Maybe the HR20 don't have enough power to power up the deca? Seems strange.
