i have a modem which allows 5 computers to have access. i have a laptop which doesn't have a wireless driver. is there any way to download a driver for windowsXP? i know i can buy a usb network adapter. any suggestions?

at first download a driver with the PC which u use to write in it at here.
and I think that u should install it in a laptop by USB memory.

or there is no problem if u buy an adapter of the automatic installation function deployment.
like this one.
