Win10: how to modify the priority of dual network cards?

Many use dual network cards ​ ​IT The home of ​​ Netizens may encounter a situation , For example, the laptop is still used after plugging in the Internet cable WiFi, You have to manually turn off the wireless connection to switch to a wired connection . How can we adjust the appropriate network priority ？ Generally speaking , There are two common methods .

One 、 Adjust network advanced settings

Windows By default, there is a location that can adjust the network priority ,​ ​Win7​​​/​ ​Win8.1​​​/​ ​Win10​​ Theoretically, it has this function , In the network and Sharing Center , The specific steps are as follows ：

1、 Right click the network icon on the taskbar , Get into “ Network and Sharing Center ”

2、 Click on the left “ Change adapter settings ”, Here's the picture ——

3、 Press keyboard Alt Key to call up the menu bar , And then click “ senior → Advanced settings ”, Here's the picture ——

4、 At this time in “ Adapter and binding ” Under the tab, you can adjust the position of the available connections （ Click a connection , Press the up and down arrows on the right to adjust , Here's the picture ）

▲ caption ： This picture was found in the Microsoft community ,IT Home computer only has the following figure ……

▲ caption ： you 're right , There is no such thing as “ Adapter and binding ”

However, some users reported that their computers did not “ Adapter and binding ” TAB （ For example, the three computers I have in hand , Pictured above ）, Or some users reflect that ​ ​Windows10​​ The above settings in cannot be saved （ It is said that Microsoft is Win10 This setting has been invalidated in ）, How to adjust the network priority at this time ？

Two 、 modify “ Interface metric ”

This term may be unfamiliar to some users , So-called “ Jump point ”, I.e. routing . A route is a hop . Data transmission needs to go through multiple networks , Each passing network device point （ Capable of routing ） It's called a hop , The address is its IP. Metric is an accumulator of how many hops have passed , In order to prevent useless packets from spreading on the Internet . Specifies the integer value of the desired metric for the route （ The scope is 1 ~ 9999）, It is used to select the route that best matches the destination address in the forwarding packet among multiple routes in the routing table , The selected route has the minimum number of hops . Metric can reflect the number of hops 、 The speed of the path 、 Path reliability 、 Path throughput and management properties .

Okay , Talk about how to set the priority by changing this value . Simply speaking , If there are multiple connections in the computer , Which connection has a small metric , Which priority is higher . But don't be capricious , You have to follow the basic law , That is, set according to the actual situation , The general setting method is as follows ：

1、 Get into Network and Sharing Center → Change adapter settings

2、 On the connection to be modified Right click , choice “ attribute ”, Here's the picture ——

3、 double-click “Internet Protocol version 4（TCP/IPv4）”（ If it is IPv6 Just choose the following “Internet Protocol version 6”, The setting method is the same ）, Here's the picture ——

4、 Click on the “ senior ”, Then deselect “IP Set up ” Under the tab “ Automatic jump ”, Here's the picture ——

5、 If this is a high priority connection , Just put “ Interface metric ” Change it to 10, If it is a low priority connection , Just change it to 20, Here's the picture ——

This change is first because Many users have tried it successfully , In particular, users whose first method is invalid . As for why, change to 10（ Generally used for wired network ） and 20（ Generally used in wireless networks ）, The following standards can be referred to ：

But still remind users , It is better to use the default interface metric “ Automatic jump ” Relatively safe , And through IT Home test , stay Win10 in , Many devices that use dual network cards give higher priority to wired networks . If your device does not set network priority according to your requirements , It can be modified by the above method .
