Building the driver

• gcc -- The same GCC version used to compile the kernel
  • otherwise, "Invalid module format" errors may occur
• subversion -- If you choose to get the most recent MadWifi code, you'll need to check it out of our Subversion repository.
• make -- Used to automatically build programs.
• perl -- Used by Madwifi Makefile to generate code
• madwifi -- Download the latest MadWifi driver.

Configuring the wireless card

• iwconfig -- Used to connect to a wireless network; often called wireless-tools by distributions.
• wpa_supplicant -- Used to join a network with WPA encryption; often called wpasupplicant by distributions.

Please check your Linux distribution for more specific information.
