Now computers are often connected to WiFi to surf the Internet. Sometimes they still need to connect the network cable for network stability, but what should we do when the computer can't access the Internet after connecting the network cable? Here are some solutions that I sorted out about the computer can't access the Internet after connecting the network cable for your reference.
The network cable is in poor contact with the computer or falls off. At this time, the network connection icon in the lower right corner of the computer generally displays a red fork
The copper wire inside the network cable is short circuited. This situation usually occurs in rainy days. Because of damp or rain, two or more twisted pairs of plastic on the surface are bitten off by rats and short circuited.
When the IP address conflicts, the computer will generally pop up a prompt box. We can enter in the CMD command line window to obtain the IP address again, or manually configure an IP address in the IP attribute
ARP virus is found in LAN computers, which generally requires network engineers to gradually find the internal poisoned computers
Finally, there is another situation: the network of the whole company is disconnected, so I won't say more.
This problem usually occurs when your local connection is disabled. The solution is as follows: open the control panel
Find -- network and Sharing Center (or network and Internet)
Select and open change adapter settings
Enable local connection
Connection (required network)
