If you have an output similar to: <pre> wlans_run0="wlan0" ifconfig_wlan0="WPA DHCP" </pre> Your WiFi is configured, but it might be down. : <code>sudo ifconfig wlan0 up</code> Now it should work.
如果输出类似以下:
wlans_run0="wlan0" ifconfig_wlan0="WPA DHCP"
则 WiFi 已配置好,可能还未开启,运行
sudo ifconfig wlan0 up
应该可以工作。
