If you are going to use BT5, please, forget about windows. You need to read a little bit about linux...Here nothing is automatic. Nothig is taken for granted (drivers installed, network services started, etc).
First you need to know if the system is seeing the wifi cards...If not, you need to start the network services....
Open up a terminal, type: ifconfig
See if any device is available (eth0, eth1, wlan0, wlan1, etc..).
If no device, except "lo" (local) is available, type : /etc/init.d/wicd start (the interfaces are brought up, start discovering dhcp server, etc)..
Then check again if interfaces are available: ifconfig
Try this first....
And please, this is not windows, this is linux, and you need the terminal (it's your spoon, fork and knife when eating). Sorry, no drag&drop, no automatic stuff, no installation wizards...need the terminal and commands.
Hope my comments do not bother you, but need to read about linux if you are trying to get into this..
