I have a similar problem and have not been able to connect.
Slingbox worked fine until mid-January and then stopped. No changes were made to router or security software. Settings are correct.
Whether trying to connect from a PC at home or away, or through iphone app, I get the message "trouble connecting to the network".
I have tried unplug and pressing the reset button for 30 seconds - no luck. Both lights on the front are on. When trying to reset, the lights don't flash which makes me think it is a Slingbox hardware issue. The lights on the ends don't come on either.
The Slingbox SOLO is not able to get a good connection to your network. Is the Slingbox connected directly to the router, or are you using a set of powerline adapters? Since the network light is not turning on, there are a few things you could try.

If that does not help, you could also try purchasing a new power supply. If the power supply fails, it may not be able to hold settings properly.
Here is a link to purchase a new power supply:
