We need you to be more specific. Unfortunately, your post is not clear enough and we need you to provide as much information as possible. Do you have the Slingbox connected hardwired to the router? Are you using the SlingPlayer or watch.slingbox.com?
We recommend that you hold the reset button for 15 seconds and then run the setup again, please take a look at these links,
If your router isn't on the list, choose the one that is the most similar.
Let us know how it works.
