Ethernet disconnects on PC

[nowmat]

Hello. I lose my wired connection to my PC while playing a game. The problem is on my end, not the game server's and it happens every day.
I have also experienced disconnections from the network while watching streams.

Filtering is disabled, PC is set as PlayStation. SmartBosst game priority, I have tested applications/devices and nothing changes.

Wi-Fi does not disconnect at that time on other devices. I also tested turning off Wi-Fi and connecting wired only the PC, and the issue persists.

This happens on software versions 4.0.540 and 4.0.645.

I set the PC's IP address to DMZ, but it didn't help.

I performed a hard reset, but it did not help.

The log is attached; the disconnection begins at 10:51.

In the taskbar, at the moment of disconnection, the tray shows as if I had removed the cable.

I plugged the Ethernet cable into another port, but it did not change anything; the disconnections continue.

When I'm not gaming and just browsing the internet, everything works fine, but when the load is moderately higher, such as when gaming, it disconnects.

What else can I do?
