So I despirately needed to get 2 computers networked to my 'Telstra Wireless Next-G' internet... however, no matter what method I tried, I couldn't make the connection... The hardware setup consisted of 2 computers running Windows Vista, a USB Next-G Modem on 1 machine running a cross-over LAN cable between the two machines...
I discovered a method that works well with Windows Vista machines. (Windows XP is not such an easy task!)
