You'd need a wireless adapter to use wireless internet. Your PC can have a built in WiFi adapter, or you may buy a WiFi PC card or USB WiFi adapter, etc to have wireless internet on your PC, in which case your PC would connect directly to the wireless hotspot.
Your modem would have a wireless access point, which allows wireless capable devices (like your wireless capable PC or phone) to connect to internet (share) via your router (which uses your telephone cable for WAN).
not sure why this was over there, doubt it will help
