I am having the exact same issue with my HR24. It drops off MRV every day or so. My other receivers (HR20-700 & HR21-700) stay on fine. My system is wired correctly. Keep having to reset the HR24 and then it comes back up and connects fine. I may try a full network power-down/reset tomorrow if this keeps up. Very annoying.
Deca readings range from 242-249. Coax plugged directly into HR24, nothing into its network jack, Deca units on the HR20 & HR21, Deca unit connected to my router with power adapter. PI inserted on one of my coax lines (After the 8-way green label SWiM switch).
Does that sound right?
First: your reading are good/great.
You're not the only one that has this problem [though I'm not one of them].
I wouldn't waste my time resetting the SWiM, since it has nothing to do with the DECA network. If I had SAT signal issues, then yes resetting the SWiM would be a good idea, but SWiM & DECA have zero interactivity.
I would reset my router first [pulling the power cord for a couple of mins should do this].
Next would be to pull the power cords on the receivers [or pull all the power cords while you're doing the router] and then let them boot up one at a time before moving to the next.
See how long this works, or doesn't.
Next would be to remove the ethernet cable from the DECA to router and reboot all the receivers. This will drop the internet and cause each receiver to pull its own IP address.
See if this keeps them all showing the playlist and updating them. Give this a couple of days to know if their all playing nice.
If so, then this might suggest there is a router problem, since it works without the router, BUT from another poster that changed their router, it didn't resolve the problem.
"THERE MAY BE" a problem with a few HR24s that is causing this. The more data/testing/users that help by running through the steps above, "we hope" to narrow down what this is.
