无线网卡设置

由 FsTy, 8 十二月, 2015

1.设置无线网卡：
#sudo nano /etc/network/interfaces

source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

# sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
        ssid="603"
        psk="6666--3333"
       key_mgmt=WPA-PSK
        priority=2
 }
network={
        ssid="6032"
        psk="6666--3333"
        key_mgmt=WPA-PSK
        priority=1
 }

If a wpa_supplicant.conf file is placed into the /boot/ directory, this will be moved to the /etc/wpa_supplicant/ directory the next time the system is booted, overwriting the network settings; this allows a Wifi configuration to be preloaded onto a card from a Windows or other machine that can only see the boot partition.

意思简单来说呢就是把配置好的 wpa_supplicant.conf 文件放在 boot 分区（烧录SD卡完后，在Windows 中只能看见一个 boot 分区），那么启动树莓派的时候会自动连接上WiFi
