I had an HR34 and two C31's installed on 6/17 (Monday). Also a new SWM LNB, splitter and DECA for whole home DVR service. DECA is hard wired to router for internet access. The HR34 and two C31's are the only units. Saturday the HR34 became VERY sluggish to respond to the remote and the video was freezing for 5 to 10 seconds at a time. Audio did not freeze. Both the TV's attached to the C31's were displaying gray screens. I rebooted the HR34 with a RBR and everything was OK. I ran a system test and the two error messages I got were "not connected to a phone line" and "dropping network connections". I understand you get the "dropping network connections" if you turn off the C31's which I have been doing. This morning the exact same thing happened again. Other than the two issues things have worked well. I've searched and found some similar problems but none that had a definite fix. All three units appear to have the latest software installed. Before I call DirecTV does anyone have any ideas on that the issue could be?
