These OpenWRT settings are documented [http://wiki.openwrt.org/doc/uci/wireless#common.options1 here].
I'm not actually sure what the noscan feature does or whether it's a good idea. There's a warning that it will violate regulatory requirements, but I'm not sure if it's related to DFS or if it's something else. - ([[User:Juul|Juul]] ([[User talk:Juul|talk]]))


The ath9k driver does not yet have support for a 802.11n-only mode (also known as greenfield). The closest is 802.11n+a. Apparently you can prevent 802.11a nodes from associating somehow. [http://comments.gmane.org/gmane.linux.drivers.ath9k.devel/10735 source].
