The Internet does not work via LAN cable on a PC (special case)

Hello. I have the following problem. I have connected and configured the router, access to the Internet is available. But here is the problem: the Internet on the PC does not work, but when I connect to the router on my phone, the Internet is there, and works perfectly. How can I solve this problem?
P.S. Automatic detection of IP addresses on the computer is set, as was in one of the solutions, but it was done before, and did not help.

Hello. We have a separate article with solutions to this problem. If you haven’t read it yet, be sure to check out /solving-problems-and-errors/the-internet-sores-not-working-on-a-network-cable-from-wi-fi-router/

There can be many reasons why the internet may not work on a cable from a router. Note that once the router is installed, you don’t need to run any internet connections on your computer.

If the tips from the article above do not help, then in the comments below, describe in detail what Windows you have, what is the status of the connection. Go to “Control PanelAll Control Panel Control Center Network and Sharing Center”, and see if there is a “Local Area Connection”, or “Ethernet” adapter, and how it works.

Also, you can see if there is a network karat in the Device Manager.

Well, it is good to connect another computer or laptop to your router via cable. See how it works. To know exactly what the cause is.
