Problem with network

[mokyklat715dd02ed]

Hello, yesterday for some reason the wired internet on three of my PCs stopped working. All computers have MSI motherboards: H310M Pro-M2 (MS-7B28) Serial number I616750765 and H110M ECO (MS-7994) Serial number H616752951. The problem determination shows that the internet cable is not connected but the cable with the Asus computer works fine.
Please I need help.

Hi
It is near impossible that all 3 computers broke down at the same time.
The only thing that comes into my mind is that a Windows update messed up drivers.

Thanks for the reply, I appreciate it. I'm in complete despair. I've probably tried everything I know, as well as what I found in online guides, and nothing works, neither reinstalling drivers, nor updating. Updating the bios didn't help either. My last hope is a clean install of windows.

Try to uninstall most recent windows updates. If this happened across all 3 computers at the same time, then that's what most likely caused it.

Hello, I finally managed to figure out what happened to my computers. It turns out it was a failure of channels 16, 23 and 8 of an unmanaged d-link switch. All other channels work fine, but these three work by constantly turning off. Two of the channels with the Lenovo computer disconnected only a few times and for very short periods, while one channel disconnected consistently because of this and managed to understand what was happening. So far, this is the most craziest experience I have had in searching for such a malfunction.
