waylonrobert, thanks for your replies. I am feeling more encouraged after reading your replies that the setup will continue to work. Good to know your ethernet setup's been working flawlessly. I'm thinking the overnight firmware update might have have been responsible for the HR24's dropping itself from the network. Can't think of any other reason, but I'm not an expert... Regarding SWiM, yes I am on SWiM. The extra cable issue was what the tech rep suggested, even though I explained I had a SWim install, his comment was that the DECA adaptor would come downstream from the dish, and would have to be near the router, for the ethernet cable to be attached to it, so then from the DECA adapter, a cable would go to the splitter, then the splitter to each box. The existing splitter is on one side of the outside of the house, the router in a closet on the opposite side of the house from the splitter and the splitter connects to internal house wiring . The cabling would go from the dish to the DECA to connect to the router, and then from the DECA back across the house to the splitter. I plan to keep the appointment, at least for the next week while I monitor the situation. It's coming at n/c to me, and I'll see if I can reconcile my feelings with the possibility of faster response time with DECA, vs. more wiring coming into the house.
