Thanks for posting in the forums! I'm sorry to hear you are unable to connect to your Slingbox after moving it to a different location.
I understand that you have the same ISP at the new location, however, in order for the Slingbox to get a network connection from the new network, you will need to reset it to factory settings. After you reset your Slingbox to factory settings, you will need to go through the online setup at setup.slingbox.com.
Below is a link to an article from our support site that explains how to reset your Slingbox to factory settings:
Hope this helps!
