2、添加hostapd、iptables指令

3、STA測試腳本

ifconfig wlan0 down
ifconfig wlan0 up

killall -9 wpa_supplicant

wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_supplicant.conf

killall -9 udhcpc
udhcpc -b -i wlan0
           

4、AP測試腳本

ifconfig wlan0 down

killall -9 hostapd udhcpd

hostapd -B /etc/hostapd.conf

ifconfig wlan0 192.168.2.1 netmask 255.255.255.0

mkdir -p /var/lib/misc/

touch /var/lib/misc/udhcpd.leases

udhcpd  -f /etc/udhcpd.conf &

echo "1" >/proc/sys/net/ipv4/ip_forward

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
