Please help, I have been waiting for two weeks for help with the problem of a server that disconnects the wired Internet!

Hello again, I am writing to you for the second time, because no one answered my first message (my number is MC-230559), I also wrote to Twitter, no one answered there either. All this time I didn't just sit there, I reinstalled all the drivers, windows, java, minecraft, the minecraft launcher, waited for version 1.17.1 nothing helps, please help! I am ready to throw off everything that you require, logs, etc. When starting the server, everything also works at first, and then the Internet abruptly turns off, only restarting my PC helps, please respond to my appeal, the hope is only on you, there are people with the same problem as me on other forums
Here is the text of my last appeal:
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.
