Can my computer be connected to the Internet via a wireless modem?

There really isn't such a thing as a "wireless modem." Even though you only have a single PC, what you need to do is set up a standard WiFi wireless network, using a wireless router.

Your modem will directly connect to the wireless router via a cable, and then your PC will connect to the router wirelessly. (You'll also need a WiFi adapter for your PC, of course.
