Vodafone wireless internet sharing connection

[S.O.S]

I'm just about to buy a wireless stick from vodafone as its bloody cheap. My question is, at the moment i have a modem connected to a network card which runs the internet for two computers on the shared network. Can i do the same with this internet stick, can i share the internet with the other computer as before?.

just a few answers for a few question that might pop up.

ADSL n/a.
Cable n/a.
Naked n/a.
Dial up pathetic not wanted.
Wireless only option.
