I have been able to connect my TP to my PC on my local network with no problems. Everything works just great.
When I put my TP on a different WiFi network and tell it to connect the screen goes black and sits there. If you look at the PC it will tell you that a Web OS device is connecting, then the screen resizes, then nothing -- -- after a few moments the screen goes back to normal size. If I kill the program, bring it back up , and then try to connect the TP tells me that there is already another device connected to the PC and it will not connect.
I have tried using both the network discovery and entering the specific IP address for the network on the TP and the results are the same.
I have used other streaming programs for video and never encountered this kind of problem. None of those programs are active on my machine when trying to do this.
