linux下通过wpa_supplicant实现wifi方式上网

wpa_supplicant -iwlan1 -Dnl80211 -c/etc/wpa_supplicant.conf

认证通过后通过dhcp可获得动态ip
udhcpc -i wlan1

/etc/wpa_supplicant.conf主要配置如下
WPA-Personal(PSK) with TKIP and enforcement for frequent PTK rekeying
network={
        ssid="HUAWEI GRA-TL00"
        scan_ssid=1
        key_mgmt=WPA-PSK
        proto=RSN WPA2
        pairwise=CCMP
        auth_alg=OPEN
        psk="12345678abc"
        #psk=a27eac44bca4a52e85adc080b6f7aee27d59d04bebced870eda9a06ddab0d184
