Basically right now...
The jury is still out on whether the router was causing WH issues. so far so good...
One receiver may be having issues and need to be replaced....
One old SD DVR is set to only 1 tuner because
1. we wanted to continue to have the extra old small non HD TV sitting in the living room for watching an extra game.
2. I had to pay a lot to have the 2nd DVR 4+ years ago when getting DirecTV so I chose to hang on to it for the area that did not need a HD box of any sort.
So...what benefits would come from Shades228's advice here?
The benefits would be:
Remove potential interference from the PI
Remove doubt as to whether the receivers were fighting over a SWM channel issue
Get your installation up to "code"
Allow you to have it setup so there is less overall "loss" to receivers by removing that 8 way.
Rule out everything else to isolate if it's a bad receiver before swapping it out.
Add second tuner capability to your R16 (I know it's not very important to you)
Also it would be needed in the future for any expansion.
I guess see my original post about this yesterday for all details, but living Box would get 771a error intermittently and the test run by pressing info button showed error saying disk alignment. Tech came out and did much more and then things started happening.
Which is another reason I think that they should have done this already. 771a is the receiver not seeing the SWM.
