linux平台WIFI测试方法 一：加载WIFI驱动 insmod /lib/modules/wlan.ko 二：给WIFI设置IP，确定IP在自己的网段： ifconfig wlan0 192.168.0.123 up 三：在/etc目录下，修改wpa_supplicant.conf文件： 默认内容为： # WPA-PSK/TKIP ctrl_interface=/var/run/wpa_supplicant network={ ssid="armeasy" scan_ssid=1 key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE pairwise=TKIP CCMP group=CCMP TKIP WEP104 WEP40 psk="phosphor" } 注意，这里ssid表示WIFI名称，psk表示WIFI密码，请填写自己对应的名称和密码。 四：建立工作目录 mkdir –p /var/run/wpa_supplicant 五：执行如下指令： wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf & 如加载成功，会有如下打印： [root@x210ii /]# wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf & [1] 133 [root@x210ii /]# [ 466.153272] [rtw_wx_set_pmkid] IW_PMKSA_FLUSH!
