I've now downloaded and installed BackTrack 4 Beta onto a DVD in order to fiddle around with it before I install it on a USB Flash Drive. However, I am not quite sure how to connect BT 4 to the Optus 3G Network.
On my Windows box, it is simply a matter of firing up the Optus Wireless Network software and hitting connect. The setup procedure on BackTrack 4 (and Ubuntu) is significantly more strenuous.
Any help in enabling Backtrack 4 Beta to connect to the Optus 3G network will be immensely appreciated!
I had no issues with bt automagically recognizing my 3g modem and using it. Just /etc/init.d/networking start, then go to your networkmanager, right-click, see your modem, click on it, connect. It's that easy. At least with most 3g modems (USB) it is so.
