Minecraft server disables ethernet on version 1.17

Hello, I ran into a problem when creating a server. I created a server on the version of minecraft 1.17, we play on the server in 2 (the configuration of my PC: RTX 3070, 32GB of RAM, intel core i5 11600k, the motherboard on the Z chipset), after 15 minutes of the game cuts off the Internet, the Internet is completely lost ( WI-FI works and Bluetooth too), only restarting the PC helps, this was not the case on later versions. Please help me solve the problem, I am not the only one with this problem, I have found similar problems with version 1.17 on other forums ( in particular on the minecraft wikipedia). If nothing is done here, then when can I expect an update and fix of the official server core? I am very much waiting for your answer, thank you.
