Wireless network with USB internet modem.

[superman22x]

I have sprint mobile broadband, and it comes in like a tethered cell phone. It's a usb modem, that recieves the internet from cell towers. I than have my wireless router hooked up to my ethernet port. I have the internet coming in on my sprint mobile broadband shared, and my psp can get it, and if I plus something else into the ethernet port it can get internet, so I just got a wireless G reciever and I just need some instruction on how to set it up on my other computer just so that other computer can recieve internet, thats all it needs.

Thanks

Oh and my computer has vista, the other has XP.
