No one will be giving you tips about Windows XP programs here, given that this forum is for BackTrack Linux.
How do you configure a wireless card in BT and connect to the Net?
- Ensure the hardware driver for the wireless card is loaded. Use the lsusb or lshw commands to find the device name if necessary, so you can research what the name of the driver might be. Use various module management commands like lsmod and modprobe to check if its loaded.
- Connect to a wireless access point (there are command line and GUI methods, and the specific details will differ depending on what type of encryption the AP uses)
- Configure the IP address and subnet mask for the interface, and an appropriate DNS server and default route for your system, either manually of automatically from your AP using DHCP.
Considering that Backtrack is a Penetration Testing distribution though, we generally expect that people using it will have the base knowledge to work this stuff out on their own.
