I have been battling the same problems with the SlingAdapters, 922s, and DISH Remote Access for more than a month. We have never gotten either a 922 or SlingAdapter to work correctly providing remote access to a computer via DISH Remote Access. This is using 3 different ISP's, 3 different networks with internet connections speeds up to 3 mbps. It makes no difference whether the computer is attached to the same network as the SlingAdapter/922 or a remote network. On rare occasions such as the last full moon it has worked for about 3 hours and then stopped. Strangely, it has worked very reliability providing mobile access to the both the IPhone SlingBox App (922 only) and DISH Remote Access App (922 and SlingAdapter). For example, on my IPhone operating on my home WiFi network, I have connected to both a SlingAdapter and 922 without any issues. I was not able to connect to the same devices on a notebook computer attached to the same network.
In the case of remote computer access, it generally fails during the authentication phase. Due to copyright restrictions, I suspect the Sling device needs to set up some type of secure connection between the remote computer and the Sling device. It's the failure of this secure connection that is killing the process and it is likely that failure of this link maybe ISP related or timing related. I don't really believe DISH or Sling has properly tested these devices the way consumers would use them.
In addition, when you add Google TV to the mix, things looks a little shaky. For example the recommended means of connecting a 722 or 922 to Google TV is through the ethernet port on the Google TV appliance. Google TV then bridges the receiver to your router over wireless. You can't do this type of bridge unless you disconnect the home plug adapter tied to your router if you happen to have one, since the receiver defaults to the home plug for network connection (At least I haven't found a way to turn it off in the receiver. Once an ethernet cable is connected and the adapter gets an address, you can connect the homeplug adapter at the router again.) However, when you set things up this way, the limited success I had with the SlingAdapter connecting to my Iphone then doesn't work any more. The only solution I found, was installing a small ethernet switch behind my television, connecting everything there, and then hardwiring it to my router.
The last issue started yesterday, my 722 became extremely unstable and slow and the off air tuner refused to work. After two hard resets with poor results, I disconnected the SlingAdapter and reset again. The receiver then recovered normally.
I really don't think either of these devices is ready for prime time. Google has realized this based on today's press reports. I don't think DISH techs in the fields are ready for this either.
