You can get a wireless router for cheap, hook up your Internet Modem into the back of the wireless router (so you can use it with Internet as well as your own local network). You can just hook your computer up to the router using an Ethernet cable and then connect your phone up to the wireless router.
X = modem from your Internet company
O = router
- = Ethernet wire
C = computer
P = Your phone
X-------O------C
P (no wires)
Your router has it's own name (this name is known as an SSID)
Your phone then should connect to a wireless network by selecting the name of your router (SSID).
