Welcome to the official Linux Wireless wiki
This is the main source of Documentation for the Linux wireless (IEEE-802.11) subsystem. This wiki features information for end-users, developers and vendors.
This site covers all the new 802.11 drivers, the new core mac80211 and cfg80211 components along with the new userspace and in-kernel nl80211 configuration interface. New nl80211 userspace applications are also documented.
For news on driver updates it best to simply refer to the ChangeLog of the stable release series. This will cover both Linux kernel changes on each release and also compat / compat-wireless updates. As of August 14, 2012 the compat-wireless project has been renamed to compat-drivers and all future releases starting from v3.7 will be made through the new backports wiki page.
