Do you have DHCP turned on on your router? If not, you will need to do so initially. When you run SlingPlayer - do you see the Slingbox or not?

I think you are taking the right troubleshooting steps - connect the Slingbox directly to the router. If that isn't working, then do a factory reset by holding down the reset button for about 20 seconds until all the lights start blinking. You said you did a reset but did you get to the point of the reset?

Also, is this a new Slingbox or did you buy it used? I've seen used ones have a problem with their power supply and while the box powers up it doesn't work right since the supply is bad. If you bought your box used, it is possible that you have a bad supply.
