Hooking up internet wirelessly without a wireless antenna?

[saltuponwounds]

So, I have plugged up my PC and have everything working, the only problem is I broke the wireless antenna and can't bring my internet source upstairs to make my connection wired. I have a Mac that can connect wirelessly and is right next to the PC. Is there a way for me to like use an ethernet cable to plug into the Mac to get wireless for my PC or to just get internet wirelessly in general?

Have you considered powerline adapters?

Either get a pci-e wifi adaptor (check if you have a pci-e slot free on the mobo), get a USB wifi adaptor, or look at using powerline adaptors (these plug into the wall sockets and use your houses wiring as ethernet essentially).

If the Mac gives you the option to share its network connection and if it has a network port then yes you can. How to do it I have no idea. I'm not a mac user.
