此方法经适用于树莓派3或已安装好无线驱动的树莓派 pi 和树莓派2

 

登录树莓派后输入命令：iwlist scan  查询所扫面到的wifi信号，确定准备连接ssid在扫描列表内

［方法一］

编辑wifi文件
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
在该文件最后添加下面的话
network={
  ssid="1024"
  psk="password"
}
# 引号部分分别为wifi的名字和密码
# 保存文件后几秒钟应该就会自动连接到该wifi
# 查看是否连接成功
ifconfigwlan0

［方法二］

修改/etc/network/interface文件

auto lo

iface lo inet loopback

iface eth0 inet dhcp

auto wlan0

allow-hotplug wlan0

iface wlan0 inet dhcp

wpa-ssid   接入AP的名字

wpa－psk   接入AP的密码

保存文件，然后运行如下命令重新启动网络！

sudo /etc/init.d/networking restart
