How to connect Wii to PC to share the PC's internet.

I have a wii, I have a PC.I have an internet service that is called "wireless" but only works through the router they provide, basically I can connect the router directly to my PC or directly to my Wii.I wish to be able to run the internet on my wii but through my PC. basically I wish not to use a router, I wish to use a cord connecting my wii to the PC and I guess share the internet but I would not know where to start..

Unless you've got two ethernet ports on your PC, it's not going to happen.
