It seems that you are having some issues with your Slingbox SOLO does not keep the connection after the first attempt.
We encourage you to provide further details about the network your Slingbox is attached (network layout) and also if this happens from remote locations. Make sure to include as many details as possible, this way, the community will provide you with further details.
I have been experminting and it seems to be a problem with my WiFi router/firewall. The Solo is outside the router/firewall, and if I connect my client outside also then I have no problem reconnecting. When I cross this device is when I have the problem. I plan to replace this device with a new one that supports higher data rate WiFi so I will not try to fix this issue now. I think it is in my port forwarding rules on the firewall so that is ok. I mostly connect from the outside so that is good also.
Thanks for getting back to me.
