qca9531wifi ap切换成sta

Zihol

自己写了个脚本，但是却发现，即使uci set了mode为sta,但是实际上并没有改变成sta,有没有知道是什么原因的？

bingo,但是我的网卡连接不到驱动 = ， =
root@OpenWrt:~# wifi up
phy for wifi device wifi0 not found
wifi0(qcawifi): disable failed
Configuration file: /var/run/hostapd-ath0.conf
ath0: Could not connect to kernel driver
Using interface ath0 with hwaddr 78:a3:51:f0:00:f1 and ssid '9531juzi'
random: Only 17/20 bytes of strong random data available from /dev/random
random: Not enough entropy pool available for secure operations
WPA: Not enough entropy in random pool for secure operations - update keys later when the first station connects

奇怪的是，假如我只有ap的时候，是没有wpa_supplicant的守护进程wpa_supplicant -B -P /var/run/wifi-ath0.pid -D athr -i ath0 -c /var/run/wpa_supplicant-ath0.conf ，然而sta要连接ap好像需要认证，我猜可能是没有这个守护进程，所以验证不了，故即使uci set了mode，还是起不了作用。所以说，要怎么解决？
