I've had problems before. Sometimes I wasn't able to connect from my Iphone but at home it was ok on PC. I was setting up again and everything would be fixed.
A month ago I was watching on a PC out of home. I turned it off for a while. Then when I wanted to tried to turn it on after an hour it didn't work.
Now it doesn't work anywhere.
I've reset the system but now I see my slingbox unconfigured. When I try to configure I get the
"Your Slingbox has been disconnected because of a poor Internet connection. Try connecting again" message.
It has been a month. Doesn't get well. I didn't change anything. Same router, same connection, same PC to setup, same iphone. No firewall, even no antivirus.
I'm checking my upload speed, it's not poor. 0,87 mbps.
I understand that you are not able to get the remote connection to your Slingbox SOLO, since it stopped working all of a sudden. The following link will allow you to get the steps to follow in order to find a solution for this issue.
