I believe the "NEW AND IMPROVED" way DirecTV is pushing, is using the HS17 with the satellite Gemini boxes, which are similar to the DirecTV Stream Gemini boxes, but with different firmware. The Gemini is an Android OS box that runs the genie client software to allow it to connect to the HS17 over the network, wired or wifi. It also has the google play store to allow apps to be used for internet video streaming. I have not had my hands on one yet, so I cannot give any opinion on how it works. You used to be limited to 8 Genie Mini clients with the HS17. I do not think you are able to add more than one Genie (HR54 or HS17) on the same account.

If you want info, try contacting Solid Signal. They are knowledgable and will answer your questions. Trying to get info from who you get if you call DirecTV is a crapshoot. :)
