This might have something to do with a receiver tuning to a strange channel, but since the SWiM has nothing to do with the Whole Home, it doesn't make much sense for those issues, if you still have them.
At this point I think what you can count on is that everything has been replaced, but for the DECAs & receivers.
The LNB needed to be changed again for the SWiM-16, the cables have been inspected and attended to, and the splitters have been dealt with too.
Yep still had whole home last night and again this morning so now we just watch and wait to see if it happens again.
Two boxes have been replaced -- the non DVR and the HR24 which was doing the channel switch.
Yes, no LNB and now there are 4 cables coming out of the dish.
