Thanks for utilizing our answers forum! I do apologize for any inconvenience you're experiencing with your Slingbox SOLO and not being able to connect to re-run Setup on Slingbox.com. I would advise trying a hard reset before going through the Setup process again.
Here is a link from our support site which should assist you with that:
Hope this helps!

Hello and thanks for the reply. I have tried the hard reset, but alas, despite all of the lights doing their correct stuff and both the power and netwok lights being on and solid I still cannot configure the box. The name of the box has gone to the default name and the box is registered as being unconfigured - so it would to mee look like some kind of connection exists - at least enough to give name and configuration status - but not enough to allow configuration. Have you heard anything like this before?
