wireless driver do not useful

[扛着笔记本学linux]

我的开发板上用的无线网卡是：ATH9280，在网上查了无线驱动程序，下了个madwifi，试了很多版本，编译了加载成功了，但是
#iwconfig wlan0
开发板始终没有反应，后来看了一下官网上说的ath9k驱动compat wireless驱动，修改了编译发现可以运行了：
/ # iwconfig wlan0
wlan0 IEEE 802.11abgn Mode:Managed Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
/ #
但是想设置ap模式时，
/ # iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
/ #
开始以为网卡不支持，上网查了，发现支持的，又以为驱动不支持，结果运行：
/ # iw list

貌似不是驱动的事，不知道怎么办？
