Pint says the wireless router is connected upstream via its WAN port, the empeg is being NAT'd, and the PC can't connect in to it. If that's the case, the answer is to put the wireless router in AP mode rather than router mode (if it even allows that). Posting the IP addresses would help diagnose that, and if you also post the make and model of the router, we could determine exactly what the relevant setting is called on that model.
