Your trying to share your internet connection from the pc to the mac? or from the mac to the pc?

share from my mac to PC

I'm not sure, but try this:

Go to your preferences panel
- Sharing
- sellect the checkbox:'Internetsharing'

However, i think that you can only share by ethernet, which means running a cable after all...
