家中的路由器普遍通过DHCP向连接到此路由器的客户主机提供IP配置方式，但是一般都是动态IP；
假设需要静态IP配置到个人电脑，就要在路由器上进行配置IP和MAC地址映射关系。如上篇截图。路由器端配置完，继续在本地主机配置。
我的操作系统是Ubuntu16.04，默认使用NetworkManager管理网络连接，所以首先由禁用NetworkManager
1.stop and disable NetworkManager
sudo systemctl stop NetworkManagersudo systemctl disable NetworkManager
2.drop status of NetworkManger
sudo mv /var/lib/NetworkManager/NetworkManager.state /var/lib/NetworkManager/NetworkManager.state.bak
3.edit interfaces
sudo vim /etc/network/interfaces
# interfaces() ) and ifdown()auto loiface lo inet loopbackauto wlan0iface wlan0 inet staticnetmask 255.255.255.0gateway 192.168.0.1address 192.168.0.5pre-up ip link set wlan0 uppre-up iwconfig wlan0 essid ssidwpa-ssid Tenda_68A3D8 # ssidwpa-psk wxfzwqhqq # password
4. config resolve.conf and add nameserver
sudo vim /etc/resolv.conf or sudo vim /etc/resolvconf/resolv.conf.d/base
nameserver 192.168.0.1
5. restart networking
sudo /etc/init.d/networking restart
