I have Slingbox installed on my Asus Transformer tablet. Inside my house, everything works great. When I'm at work or at a coffee shop, I can't get it to launch. It says, "Connection Failed. Please make sure your phone and Slingbox are connected to the internet". Of course, it's already connected as I can go on my browser. I just can't get Slingbox to launch. Need to know if I need to do any type of set up at home on the Slingbox itself.
