Ethernet does not have a valid IP configuration Internet has disappeared on the computer that is first connected to the Router.
There is Internet on other computers and Vireles works. Before that, I deleted programs through Control Panel > Uninstall a program and deleted 2 programs with the name Ethernet (it seems). Trouble shoot says> Ethernet does not have a valid IP configuration. What to do?

Processor Intel ® Core ™ i5 8400 CPU @ 2.80Ghz

Look in device manager and see if you have anything that needs a driver installed. Would help to know what model of pc you have or what motherboard it is if its a custom built pc. Also what operating system it has.

How to check "if you have anything that needs a driver installed"?

Can you post a screenshot of the device manager? Do you know exactly what programs you uninstalled? Were any of them antivirus/firewall programs that may have been controlling your internet connection?

This is what your device manager should look like. There shouldn't be any section extended out to show something with a yellow question/exclamation point or anything listed as unknown device.

It's also possible that if you uninstalled realtek driver that it rolled back to the previous version which is causing the problem.
 
Maybe a screenshot of the device manager can help to understand what the problem is ....

How to attach a picture here I do not see?
 
You should see an "upload a file" button between post reply and More options at the bottom right corner of the reply box. If you don't, let me know.

The only thing needing a fix is your printer. However, It seems you have Kaspersky antivirus installed and I know it can play havoc with your internet connection if you don't have it set correctly. You need to allow the network connection so traffic can flow.

Kaspersky never been a problem. How to "allow the network connection so traffic can flow"?
 
My computer is not able to get IP address automatically. I tried to use Kaspersky IP but it causes a problem.

Kapersky and/or your NordVPN are liable to be causing issues if they mess with your IP config at all. If you want to use the Kapersky product, contact their support. If not, just set it to DHCP (automatic) and let it handle it. Changing your IP with your local network doesn't do much for security anyway so not real sure what the Kapersky functionality it supposed to provide.

Click on the circle that says "obtain an IP address automatically" and then click on ok. Then try again.
 
Kaspersky is on automatic. I use to obtain an IP address automatically for Ethernet but still no success.

Your screenshot shows you don't have the correct box checked.

You need to check the top option obtain an IP address Automatically.

You can also try disabling Kaspersky from running at boot up and it should give you internet access.
 
Boot into safe mode with networking to see if you get internet. If you do then we know its a Kaspersky issue.
 
If it were me I'd completely eliminate both Kapersky and NordVPN and make sure it works under default configuration. Once it does, add back each of them one by one if you intend to use it and see what causes the issue. If you're still having issues with original configuration then might need a new adapter.
