I very recently purchased a new M2 from sling to replace a Solo I had been using. I did this because the Firestick was not supported on the Solo. I have been having a problem while using the TV with the Firestick, and what happens while using the M2 over the TV, it is fine for awhile, then a get a alert message saying "connection failed. Please make sure your device and Slingbox are connected to the internet. Also, at times while watching from my Ipad, it will go into a wait condition like it's Buffering. Truthfully, my Slingbox Solo worked better than the M2 as far as not losing the connection. I don't know if there is a setting that I can change. I have the M2 working on an Ethernet connection right now, not wireless.
