The official madwifi site is http://www.madwifi.org/

The first time user's guide for madwifi is at...
http://madwifi.org/wiki/UserDocs/FirstTimeHowTo

You can join IRC channel #madwifi on irc.freenode.net at anytime, to 
talk to the developers and support team and may get more help there. 
There are also mailing lists you can join with the details for that 
listed on the website.

The 2.4.21 kernel is quite old, upgrading to 2.6.x may be your best 
option. Here's a link to help you do that....
