First of all, I had the old school system basically 4 coax coming off the LMB. 2 coax going to each HR21 receivers. Upgrade to SWM and a big mess of wires. So the installer came out and this is what he did. 1. Replaced the LMB with 1 coax going to an outside splitter. 2. The existing 4 coax wires were still used from the prior setup and those 4 coax wires are plugged into the other side of the splitter going to each of my 2 receivers. TV1: (This is where my wireless bride is setup and used for wired cat5 internet for devices) AC/DC adapter plugged into a DCA brick. This DCA brick has my cat5 wired internet connection plugged into it. This DCA device also has the coax plugged into going back to the outside splitter. A coax coming back from the outside splitter goes to the back of my HR44-500. Nothing else plugged into the HR-44-500 except coax and tv stuff. No physical cat5 connection going to the back of my HR-44. I also checked out the settings for the receiver and it stated that wireless was not configured and ethernet was not connected (9). Not sure what that means. TV2: SWM AC Power Adapter with a coax plugged into it going back to the outside splitter. A septerate coax coming in from the outside splitter goes to a DCA brick which is plugged into my HR22-700 receiver and also a cat5 coming off the DCA is plugged into the receivers LAN port. 1. What i don't understand is why TV2 needs the cat5 going into the lan port on the HR-22 and the HR44 gets internet connection from the coax. Maybe the HR-22 can't??? 2. Why does the cat5 in TV1 need to be plugged into a DCA device and not the lan port of the HR-44? 3. I am able to go to on demand on both receivers and start a playback of a show. All this seemed a bit odd to me but maybe that is how it goes. The installer didn't understand anything about MAC addresses either as I have my wireless MAC locked. Since I'm using a bridge and that is technically wireless, he just didn't get it. I told him I needed the MAC addresses from the receivers in order for them to get IPs. He didn't understand what I was talking about. Sorry, but all this is new to me and the setup seems a little bit odd. You would think that the internet connection would go directly to the back of the HR-44 and then go to the other receiver though the coax plugged into it. But what do I know.
