I understand that you have reset your Slingbox, now, you need to know how to set it up for Internet Viewing.
The following link will allow you to get all the information you must know about the Slingbox SOLO and how to set it up.
The link gives far too much information. Allow me to pose the question differently.
Let's say I have a router (192.168.1.1) and a PC (192.168.1.100) is connected to it. The PC has the Sling software on it. I open my brand new Sling and connect the data cable to the router. How does the PC connect to the Sling?
