If your Slingbox appears to be refusing to connect to your router, even after attempting a reset, you will want to check out these articles below:
- I can't connect to my Slingbox when I am at home
- My Slingbox won't connect and won't reset; all lights are on except the network light
- Troubleshooting "Your Slingbox can't be located" errors during setup
Also, I was wondering if the Slingbox was directly hardwired to the router, or are you using some other means of connecting the two such as a powerline adapter/ wireless bridge?
Hope this helps!
