WINDOWS sets the connection speed of the network card to full duplex or duplex.

Most network cards are self-adaptive by default to adjust the connection speed and mode, but sometimes you need to adjust the connection speed to 10M or 100M. Let's first understand full duplex and half duplex:

The full duplex of the network card means that the network card can also receive data while sending data, and the two are synchronized, just like we usually call, and we can hear each other's voice while speaking. Current network cards generally support full duplex. When it comes to full duplex, we cannot fail to mention another concept closely corresponding to it, that is,"Half Duplex." The so-called half duplex refers to only one action occurring in a time period. For a simple example, only one car can pass through a narrow road at the same time. When there are two cars facing each other at present, in this case, only one car can pass first and wait until the other car opens after the head. This example vividly illustrates the principle of half duplex. Early walkie-talkies, as well as early hubs and other devices are based on half-duplex products. With the continuous advancement of technology, half-duplex will gradually withdraw from the historical stage.

method/step

1. Right-click Computer--Manage

2. Device Manager--Network Adapter--Right-click on the network card to select Properties

3. Select Advanced

4, connection speed and duplex mode-value select 10Mbps full duplex or 100Mbps full duplex, this speed is Mbps, so divide by 8 is equal to the data transmission speed.

5. Confirm completion
