Home Router Can I Connect Both A PC And A Mac To A Wi-fi Home Router?

Can I connect both a PC and a Mac to a wi-fi home router? - home router

I have received a desktop PC (Windows XP, and approximately 4 years) at home and a laptop Mac. I intend to be a Wi-Fi router, but I'm not sure that the models work with both Mac and PC from my old. Routers and other cards that I needed, if possible?
