Got mine for free from my installer yesterday (5/13) in Longmont, CO. I already had a through-the-home-power-wiring ethernet setup (that didn't work as well as the SlingLink), so had to remove that from my home (as I *assume* the two systems would butt heads).
The sling broadcast stuttered (annoyingly so, but not debilitatingly so) on my PC so we tried multiple paths from the 922 to my router. The SlingLink worked best (between that, wifi, and my own through-the-power-system adaptor). We did not try to direct-connect (removing my router, temporarily, from the system) to eliminate something in my end of things from causing the conflict, though the technician (and his manager, who is supervising 922 installs right now to gain familiarity) left me with a 5-port switch to make that process simple. I also got an additional HDMI cable (would probably cost $8 at monoprice or $35 at Best Buy) left behind.
I spent a bit of time monkeying with router settings, and maybe have cleared things up (there may have been a WINS conflict), but haven't had enough time to finish the troubleshooting. I have had other devices drop connections through this router in the past, so I didn't want to keep the Dish Network folks on site for too long, though they were exceptionally willing to work with me until we tracked down the reason for the sub-par Sling performance on my PC.
Really a wonderful experience all said-and-done. I would think that different installer shops would have different protocols regarding leaving SlingLinks, 5-port switch boxes, unused HDMI cables, etc. behind for customer use.
