With again almost 600 patches related to wireless, the new `2.6.31 kernel <http://kernelnewbies.org/Linux_2_6_31>`__ comes with many wireless changes:

-  iwlwifi continues unification between 3945 and AGN hardware
-  the often-discussed `rfkill rewrite <http://article.gmane.org/gmane.linux.kernel.wireless.general/32727>`__, along with rfkill integration into cfg80211
-  :doc:`rndis_wlan <../en/users/drivers/rndis_wlan>` starts using cfg80211 as the first full-MAC driver
-  iwlwifi support for 3x3 802.11n hardware
-  cfg80211 now handles connecting to an ad-hoc network (including wext support)
-  initial support for rt2800usb, but still experimental
-  a new wl12xx driver for the TI 1251 B/G chip
-  ath5k has enabled AP mode
-  the hwsim driver can now separate its virtual radios into groups to allow testing mesh topologies
-  there's a new driver for new Intel integrated full-MAC hardware, also using cfg80211
