Since 2018 I have Windows 10 on this new machine and since a few moths now I had finally upgraded to Windows 11. The problems with dropping ethernet connection sstarted when I updated from W10 to W11. Every now and then the Realtek Gaming2.5GbE family controller is dropping, during playing minecraft on my server at home, it disconnects and after a few seconds it connects as if nothing happened.
My Wifi network connector (Intel(R) Wireless-AC 9560 160MHz ) never used before during Windows 10, now is the only reliable connection, never dropping out.
I tried EVERYTHING i could find on the internet, resetting several times, settings on the networcard like power energy saving bla bla, even found something here that suggested all I tried too (https://answers.microsoft.com/en-us/windows/forum/all/hi-i-have-an-issue-with-windows-11-my-network/ccd5536c-7ba4-450f-8f54-5fc9011c22a4)
But the problem lies not with the drivers, I did a reinstall, a few times even, did not help any thing, the problem is WINDOWS 11 and not the networkcard.
Logic dictates if all plausable actions fail, the unplausable facts remain, and that is the interconnection that Windows 11 uses to gain datastream through the networkcard.
If I had the time, energy and willpower to reinstall Windows 11, I did that to just rule out a faulty Windows driver, but I still am pretty sure this problem lies in the top software, and not in the hardware driver.
Tell me I am wrong, and I will try to follow this up, but not directly, because of time-energy etc...
And after a brief consideration, I tried again and did follow all those steps, and restarted several times, and fired up Minecraft to test.... Not long, after 15 minutes or so, the connection dropped out again.
So Microsoft, I do hope you will look into this issue, because I cannot use the full potential of network connection through fiber-gigaspeed I recently bought into.
