Continuous UPC Polska Internet 120mb/s Disconnections: Intel I219-V NIC & Connect Box Modem Issues

Hello,
For some month I have had a problem with the UPC Polska Internet 120 mb / s. At first, the problem was trivial, if you can call it that. At the startup of the computer, I had no internet connection, to solve this problem it was enough to click "Solve problems" As shown in the picture:









And the problem completely disappeared throughout the whole PC session.
But now that doesn't help either. Internet failures are sometimes more frequent and less frequent. I checked the Ethernet cable on 2 laptops. There is no such problem. I even made a PC format to check if it was a system problem but the problem persists. Reinstalling the drivers for the network card did not help either.
The NIC model is: Intel (R) Ethernet Connection (2) I219-V.
Do you have any ideas? Modem Connect Box with wifi from UPC.
Please help!

You can also install a newer / older driver for this Ethernet controller. Check if the port does not move / is dirty, clean the contacts. I have no more ideas for quickly from the net.

Give the "Detailed operations" screen in what you posted.
And this too

This is in the detailed operations.

It should be ok because the ID number is the same.

PS. It's nice that there are some events there, but you don't know what

These are these events: / Is it normal?
Ps. I was installing these drivers. At the beginning, I noticed the lack of the net when logging into the windows account. But now it was quiet and never appeared.

So now everything is ok?

So far yes Thank you!
