A wireless adaptor can be turned into a wireless hotspot.
Buy a usb adaptor, and then use softwares like connectify me which pretty much converts your desktop into a wireless router.
However , the downside is that you will need the desktop on all the time if you use cellphones , etc too at your home.
Better get a cheap wifi router like netgear n150 classic if you are looking for a long time solution.
