I211-AT cable problem. Or is it?

[Ross-A-Tron]

Hello! I've been having a problem with my Internet connection since a week ago I guess, I use my PC as usual but periodically my PC loses the Internet connection and it says "Network Cable Unplugged" in ncpa.cpl. I contacted my ISP and they said their system showed something was wrong with my cable.

Only unplugging and plugging it in again "fixes" the issue but not for long as it may happen several times a day. And it looks like disconnecting my PC's power cord and plugging it in again also "fixes" the issue for some time.

When the issue occurs, the Cable Tests feature in PROSet shows that there's an issue apparently somewhere at the other end of my cable (where it's connected to the ISP "switchboard" (or how it's called?) that all the other consumers in my house are also connected to).

Within the last week (prior to the issue?) I did the following:

- replaced my CPU cooler, to do that I also removed the CPU from the socket and cleaned its IHS from old thermal paste, I also was forced to remove the GPU to install the new cooler;

- updated Ryzen chipset drivers.

That's it I guess. What could it be all about?

Also replacing your CPU cooler and removing the GPU to install the new cooler should not be causing this issue as the issue that your experiencing concentrates on your network connection.
