As a DirecTV user from '94, I've seen and heard just about everything from their tech support.
Right now my issue is going to be having to put a HD antenna and receiver in my RV.
But as for the Genie system. I have a whole house Genie system It had a HR44-500 receiver and a WVBRO-25 Wireless Video Bridge, which does NOT in any way, shape, nor form have a connection to the internet. Hard wire of WiFi. I have AT&T UVerse and it does broadcast a WiFi signal but WVBRO-25 does not have access to it. The only purpose of the WVBRO-25 is to "broadcast" a WiFi signal to the "Wireless Genie Mini" on each TV in the house, EXCEPT the one that is connected directly to the HR44-500.
With all the contact & research I've done regarding my RV, as well as converting my detached garage to HD (signal from the Whole House System will not reach) I have figured out that the "newwest" Genie system (what ever it's number is now) receivers have the "Wireless Video Bridge" built in the receiver (whatever their designation) and I was informed it did need an internet connection. May be only for specific packages, or some other special features.
I discovered this because I toyed with the idea of a "Whole Home Wireless" system in my RV and the internet connection was the show stopper.
So I'm just going with a Winegard Trav'ler, and a simple R24-500-C receiver. Downside is you can only record two channels at a time (vice 5 or 7 with Genie), but I've lived with that ever since I got my current RV (2005) and put the SD DirecTV in it.
