- root privileges for the machine on which you intend to install MadWifi.
- For Debian, Ubuntu and related systems run as root: apt-get install build-essential perl
- For Red Hat, Fedora and related systems run as root: yum install gcc make perl
- Generally, make sure you have gcc, libc headers, make and perl
- Linux Kernel 2.4.23+ and 2.6.x series
- Others may work, but are unsupported; also, beware if using the very latest release candidate (RC#) kernel as it may not yet be supported
- Kernel Source and Headers of running kernel (distribution provided kernel development package should be OK)
- Wireless Extensions support in kernel
- v14+ required, v17+ recommended; option CONFIG_NET_RADIO=y (kernel 2.6.22 and later: CONFIG_WLAN_80211=y)
- Sysctl support in kernel
- option CONFIG_SYSCTL=y
- Crypto API support in kernel
- option CONFIG_CRYPTO=y

Use cat /boot/config-2.6.26-1-686 grep CONFIG_CRYPTO_AES
Use the kernel config guide to help set these kernel options.
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
- C libraries -- Standard C libraries needed for successful compilation (Type: sudo apt-get install build-essential)
- 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.
