Ran a test on the HR-34-700 today and got this result: Diagnostic Code: 48-72-002 1. Home Network Interference Problem The receivers below have reduced network performance. If you are having a problem viewing recordings from these receivers, please call Customer Service at 1-1800-531-5000 and report he diagnostic code deployed above. Affected Locations: HR34/700: GAME ROOM I have noticed that from time to time the C31 client in the Master Bedroom has some pixelation and halting video. Just to add a little more information, I have 1 HR34, 3 HR-2X DVRs, and 1 C31. The HR34 is on one side of the SWM-16 and the DVRs are on the other side. A few months of ago all the HR-2X's started getting either a 775 or 771 error. I had a service call, but it all started working a week before the service call so I cancelled it since I figured they wouldn't just replace equipment. Yesterday I attempted to add a H25-500 to the same side of the SWM as the HR2X's. It worked for a little bit, but now only has a 775 code. Service code scheduled for next Saturday and I was wondering if all of this could somehow be related to a failing SWM-16. Looking to help the tech out anyway that I can. Any thoughts?
