打开terminal（用Ctrl+Alt+T打开）
1. 输入ifconfig 
打印如下：
enp1s0    Link encap:Ethernet  HWaddr 6c:4b:90:0b:53:be  
          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::1fbf:55e3:1c4c:c79d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:144897 errors:0 dropped:630 overruns:0 frame:0
          TX packets:13548 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:13441598 (13.4 MB)  TX bytes:1943215 (1.9 MB)
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:7441 errors:0 dropped:0 overruns:0 frame:0
          TX packets:7441 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1
          RX bytes:727906 (727.9 KB)  TX bytes:727906 (727.9 KB)

wlp2s0    Link encap:Ethernet  HWaddr 34:f6:4b:8e:8e:83  
          inet addr:192.168.17.208  Bcast:192.168.17.255  Mask:255.255.255.0
          inet6 addr: fe80::7b1:7fd6:cdbc:29a0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:39311 errors:0 dropped:0 overruns:0 frame:0
          TX packets:34360 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:19874047 (19.8 MB)  TX bytes:6833538 (6.8 MB)

2.开始设置IP，网关等

sudo vi /etc/network/interfaces
#静态设置IP地址
auto lo 
iface lo inet loopback 
auto enp1s0
iface enp1s0 inet static
        address 192.168.12.89（换成你的IP地址）
        netmask 255.255.255.0
        gateway 192.168.12.1（换成你的网关）
#自动获得IP地址
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
3.重新启动网卡
sudo /etc/init.d/networking restart
完成
