I'm not even close to familiar with all the ins and outs of Directv and how the setup works anymore. This is the only reason I miss the 1 LNB days :-D. So if I'm unclear or if you need more information from me please let me know. I will try to explain this as best as I can and hopefully it will make sense to you more experienced members.
Before this Last Upgrade - (little over a month ago)
Had Whole Home - 8 Tuners , 4 HD DVR receivers, Nomad connected to Router
* Basement : HR21-xxx ( I believe it was) - wish I could remember specifics but I think this is close
Internet Router ...I had little black Deca box that is connected to router via Ethernet cable. I'm also pretty sure I had an Ethernet cable going into the back of the HR21.
* Main Floor - Had two HR-24's on same TV.
* Upstairs - HR22-700
Had one cable coming from Dish inside house ...
After Update -
* Basement - HR24-500
Next to the basement DVR/Internet Router setup I have two cables coming from the wall jack.
One RG6 Cable from top jack goes into Deca box. Exiting Deca is small Ethernet cable that is connected to my internet router.
Second RG6 Cable From wall Jack goes into input labeled ' Power to SWM' on the PI29i. From the out port of the PI29i a short RG6 connects into Port 1 on the back of the HR24-500.
* Main Floor (simply put each has a RG6 cable from the nearby wall jack going into the two DVR's.
* Upstairs - HR22-700 --- Nothing changed. 1 cable from wall jack into Satellite port 1 back of DVR.
Outside into House Cabling -
4 Cables now come from dish into House into an SWM16R1-03. There are 6 ports on the shorter/top side of the SWM. it appears that the 4 cables coming in from outside(the dish) are connected to first 4 ports and the other two are left capped. On the side there are three ports. Of these three two are in use where two cables exit the SWM16R1 . Third one capped. One of the two cables from the sWM connects to a smaller splitter (msplit8r1).. The second exiting cable from the SWM goes on it's marry way into another room. From the splitter it appears 8 cables exit and run to their wall jacks throughout the house. Then along one of the long sides of the SWM are like 8 ports all capped (not used)
A few weeks ago I noticed, periodically, on the Genie and upstairs DVR the 776 Cabling Problem message. I wasn't able to ever notice if I was losing any recordings or if it was just a misleading message. I rebooted the PI, I've checked the connections of all cables coming into the SWM and Splitter, rebooting receivers, etc. etc....the basic troubleshooting stuff. Being summer, I haven't been watching a lot of TV or recording a lot. After a reboot of the PI a few weeks ago I thought maybe i had it licked. I didn't see the error message and from what I could tell no programming was affected. But tonight was the first time I noticed the issue cause a program to stop recording. A 1/2 in to a one hour show that was currently recording, my wife wanted to start watching the show from the begging using the Play List. The show was set to record from 7-8. Looking at the play list at 7:30 it said it has stopped recording because the satellite had lost its signal. Only 19 minutes had recorded of the 30 minutes. I had her go to the guide and try to restart the recording but it is then I noticed the 776 error message again. With fall programming coming up and NFL Sunday ticket I want to avoid any surprises down the road.
Are their any tests I can run to pinpoint the cause? Anything I can check, any thoughts. I do have the protection plan if that means anything. Before the upgrade I never had any issues. Of course with the upgrade and now 11 tuners in action things are different with my setup.
Thanks for your time, expertise, and for reading what I hope is a somewhat clear picture of what's going on.
