Losing network connectivity in standby even with it enabled

Hi folks

im on win version 20h2
mobo gigabyte B450 AORUS PRO (rev. 1.0) with latest bios
Ryzen 5 3600 cpu

im having some weird issue i cant figure out, with my network disconnecting when computer goes to sleep.
I have tried a lot of settings without any sucess, including trying diffrent networkcards, onboard intel I211, a tp-link pcie card, and today a new ethernet to usb linksys adapter. I checked the bios setting to make sure Gigabytes erp was turned off and other powersaving things that i assume might be related.

This is some of what i tried;
Going to power options, make sure network connectivity in standby is enabled, usb selective suspend is disabled, pcie link state powermanagment is off. wireless perfomance is set to maximum, but im only using ethernet cards.

Gone to device manager- properties- power managment, unchecked allow to turn this decive off, gone to the advanced tab, disabled energy efficent ethernet, disabled selective suspend.

I also gone to group policy manager and under power settings and sleep, i enabled allow network connectivy in standby on both plugged in and on battery (although computer is a desktop).

I dont know if this issue always been here since i went to win 10 about a year and a half ago, i had issues with computer not waking up after sleep, so i disabled sleep all together. However, i did change some settings after googling to try fix the not waking up again issue, but i cant for the life of me remember what i did. The "fixes" attempted didnt work, however it seems after some windows updates (possibly gigabytes last bios also), the not waking up issue is fixed, but im wondering if the fixes i applied is the cause of the less of network issue now.

I thought maybe the quick and easy fix was to use the ethernet to usb adapter, but no, windows still turns it off.

is there any way to see whats causing the network to turn off when going to sleep, like a log or something?
Anything in the registry that can overrule gpedit and force the network off?

at this point im not sure what to do other than trying a refresh of windows, but i rather not if i can avoid it.

Any tips and suggestions is very welcome, Thanks in Advance

Thanks for your answer.

I just checked and cfosspeed isnt installed, only gigabyte app thats installed is @bios.
I only use windows defender.

I seen many have diffrent kinda problems with the intel I211 which is on my board. i have disabled it in device manager, but unfortunatly i cant seem to be able to totally disable it in bios. It wouldnt be surprised if any drivers or something is messing this up.

Thanks again for ur answer

i double checked again for cfossspeed, its not installed as far as i can tell, not in services or under apps and features.

i have installed the latest drivers for the intel I211 from gigabyte, yes its the built in lan adapter on my board.

I re-enabled the intel 211 again now, if i go to first setting you asked me to, it says network 3 internet access. If i go to adapter settingsand status, it says ipv4 internet access and media state enabled.

All the 3 ethernetcards works fine after sleep/restart etc, but i dont want them to disconnect when computer goes to sleep.
No matter what i seem to do, network connection drops during sleep.

Hi and thanks for your answer.

thats a good question, i been trying to figure our how to get my computer to use S0 modern standby, however i havent had any luck with that so far. Im currently in S3, are you saying network connectivity isnt possible in S3?

If so, then im starting to understand more, but how in the world do i get it to use S0?

THanks again
