I am having a problem trying to share an internet connection. What i currently have is a wireless router that isnt connected to a modem, and 2 computers, an xp laptop and a vista desktop.

The xp laptop has a wide range verizon wireless usb chip and i want to be able to share that connection so the vista computer can connect to the internet through that chip. Any kind of direct cable connect is unfeasable because the computers are so far apart.

If i could share the connection so that any devices connected to the wireless router can use that internet, say an ipod touch, that would be great.

attached is a very, very crude network map of what i want.
