1. 修改 /etc/network/interfaces，添加无线网卡配置：
auto wlan0
iface wlan0 inet dhcp
wpa-ssid myssid
wpa-psk mypassword
dns-nameservers 192.168.0.1
2.
使用 static dns:
sudo rm /etc/resolv.conf
sudo vi /etc/resolv.conf
添加：
nameserver 192.168.0.1
3. 先 disable NetworkManager:
charles@china:~$ sudo systemctl stop NetworkManager.service
charles@china:~$ sudo systemctl disable NetworkManager.service
4. 重启网络服务：
sudo systemctl restart networking.service
OVER!
