Need some more information in order to help...
- Which Slingbox do you have ?
- What computer/operating system are you using ? (Mac OS X 10.6, WinXP, etc.)
- What brand/model router do you have ?
- Has it been working normally before now ?
- Why have you been resetting the Slingbox ? (more about what is not working please)
- What happens when you try to reinstall/run the SlingPlayer program ?
- What exactly are the lights doing on the front of the Slingbox ?
Any other details or clues you can write would also help.
