This article is out of date. It may contain old, confusing and wrong information. Please help improve the wiki by updating the article and correcting mistakes.

[edit] Please note there is now full wireless support in the standard initscripts - this information is obsolete

Work is currently underway to have this placed into the existing initscripts package

In order to use this, you must have a wireless-profile defined (see the Sample Wireless Profile). You must also add a WIRELESS_PROFILES=() array to your rc.conf file.
