Pi WIFI 设置以及开机自动运行

1，wifi设置

xwindow界面运行wifi config先配置一下，成功登陆

save config 文件/etc/wpa_supplicant/wpa_supplicant.conf

pi@raspberrypi ~ $ sudo cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
        ssid="xxxxxxxxx"
        psk="xxxxxxxx"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP
        auth_alg=OPEN
        id_str="home"
}
pi@raspberrypi ~ $

配置意格id_str="home"

2，配置 /etc/network/interface 文件

pi@raspberrypi ~ $ sudo cat /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet dhcp


auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface home inet dhcp
pi@raspberrypi ~ $

可能用到的命令

lsusb

lsmod

sudo iwlist wlan0 scan
