It's being sent back.
Managed to do the same thing using a wireless-n router placed in the nearest office.

Emails went back and forth to the manufacturer and they haven't responded to the last one I sent giving them info they wanted.
Did manage to get one Mac on by turning off Airport and installing a usb wireless dongle but we couldn't do that for everyone.

Using the wireless-n router will work out cheaper too - just would have been cool to have the outdoor point. :(
