This article may only apply to this case For your reference only

• Prepare the network cable
• Computer link WiFi

1.1 Computer settings WiFi share

First set up the computer WiFi share , In the link WiFi front Before plugging in the network cable The network sharing center is shown below ：

here Insert the drive board cable The situation is as follows ：

here 【 Right click 】WiFi modular Setup and share The shared object is the new Ethernet Ethernet cable

After setting up 【WiFi modular 】 Will appear next to sharing keyword .

1.2 View the host and shared network ip

• For hosts ip stay 【win+r】 hit cmd After window Input ipconfig As shown below , stay Ethernet（ Ethernet ) Adapter In Ethernet IP For this machine at present IP：
  

• View shared network IP, In the former network management center mail Ethernet see ipv4 attribute , Here is 192.168.137.1：
  

2 A shared network is set in the driver board

The key lies in
1、 Drive plate IP It is in the same network segment as this computer
2、 There will be all kinds of missing IP The problem of adopt ifconfig and route Two commands are used to check the network status of the driver board and solve

2.1 Check the network status of the driver board

After entering the drive plate Enter the command ifconfig Check the network status It is found that the drive board does not exist ip Address And there are UP BROADCAST RUNNING MULTICAST Tips

2.2 UP BROADCAST RUNNING MULTICAST solve

Input... At the terminal ifconfig eth0 192.168.137.10 netmask 255.255.255.0
Among them eth0 Corresponding ifconfig Of eth0 and ip Address and netmask Before Ethernet Below , among ip The address of It's better to distinguish it from the host At this time, check the network information ：

2.3 Host and drive board ping link

• The host adopts ping Order to try ping The drive plate has ：

• Drive plate ping host ping 192.168.137.1 -c 4

• host ping The Internet www.baidu.com

• Drive plate ping Extranet www.baidu.com：

2.4 solve ping: sendto: Network is unreachable

Input route View network configuration information , Found no gateway
defa, The driver board sets the gateway as the host ip Address ：route add default gw 192.168.137.1：

here ping Baidu ip See if ping adopt

2.5 solve ping Next bad adress problem

It is understood that this problem belongs to DNS Parsing is not correct , So set DNS Set up ：vi /etc/resolv.conf after increase nameserver 8.8.8.8 that will do

Go back to ping www.baidu.com Success means you can connect to the network

ifconfig eth0 192.168.137.19 netmask 255.255.255.0

ping 192.168.137.1 -c 4
