vi /etc/network/interfaces，修改成如下：auto loiface lo inet loopbackiface eth0 inet dhcpallow-hotplug wlan0iface wlan0 inet staticwpa-ssid  netgear          #你要连接的wifi ssidwpa-psk  1234567890     #你的wpa连接密码 address 192.168.1.110     # 设定的静态IP地址netmask 255.255.255.0     # 网络掩码gateway 192.168.1.1      # 网关network 192.168.1.1      # 网络地址#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf       #注释掉这一行iface default inet dhcp

完成设置后重启，开启wifi
