[Solved] Newly Assembled Computer Loses Network Connection: DNS Server Not Responding Error

I put together a new computer about 2 weeks ago and since I started it there is only one problem, so every now and then it loses connection to the network, which is quite annoying when you play or use a program that requires a constant connection to the network. When I scan the connection I get this error "This computer is probably configured correctly but the device or resource (DNS server) is not responding". I have tried many methods, including:
-https: //www.youtube.com/watch? v = MNbm0oBAXXw
-https: //support.microsoft.com/en-pl/help/2779064/your-computer-appears-to-be-correctly-configured-but-the-device-or-res
But neither helped. Please help
PS
The computer has internet via an Ethernet cable.

Hello. What is this LAN cable from the computer connected to?

LAN is connected directly to the router. Thank you for the answer, but I think that I have dealt with the problem in changing the network card settings options, you had to enter the above-mentioned device properties and deselect IvP 6 there

Added after 2 [minutes]:

Go to the control panel, give tasks and options for the network card, go to change the network card settings, right-click on the device we use, go to the settings and deselect IvP 6
