Realtek 2.5Gbe RTL8125 NDIS Reset Problem

I've experienced this problem too. It seems to become worse with a faster CPU, perhaps indicating some race condition. I have found that the issue appears resolved by driver version 10.046, HOWEVER, Microsoft has a penchant for backing out the fixed driver in favor of an older driver signed by MS. This has happened to me twice now, every time the system pulls down a new Insider Preview update. A manual re-install of the updated, signed by Realtek driver again re-resolves the issue. Beware.

To anyone still checking this thread, the one on the MSI forum is way more active. To my surprise a user called plentauskas19914d202ca posted a temporary fix that worked for him in that thread. It's basically like alot of other "fixes" aswell, alot of power saving settings in the driver settings that need to get changed. Unlike all the other "fixes" this one actually seems to have worked for me. I recreated all the exact settings he shared on the forum, and since like a week or so, I have had NO disconnects whatsoever. Be aware, other than me and plentauskas these settings did not seem to help any other user with the same problems.
So yeah, it does not seem to work for everyone. But you can give it a try, it's only about changing a few driver settings and then rebooting.

The settings:
You have to go the the Device Properties -> Advanced and disable:
Advanced EEE
ARP Offload
Energy-Efficient Ethernet
Gigabit-Lite
Green Ethernet
Interrupt Moderation
IPv5 Checksum Offload
Large Send Offload v2 (IPv4)
Large Send Offload v2 (IPv6)
NS Offload
Power Saving Mode
TCP Checksum Offload (IPv4)
TCP Checksum Offload (IPv6)
UDP Checksum Offload (IPv4)
UDP Checksum Offload (IPv6)

And of course in Power Management disable Allow the computer to turn off this device.

NOTE FROM ME:
I have also set speed&duplex to 100 mbit/s full duplex
I DO NOT KNOW if this changed anything fix wise, I just did it because I remember reading this in another, old post. (this setting alone did not fix it for me)

Again, thanks to plentauskas19914d202ca from the MSI thread for this fix, which worked for me, and hopefully works for some of you guys aswell.

Often i get above 110MB/s copying back and forth between these 2 PCs here and sometimes it is stuck to 70-90MB/s. Maybe after several power savings and waskeups during the day?
Doing internet things also slows down the network copy speed. This may be due to Qos in the OS or the drivers Qos.
I don't know other hardware does better. I never really watched the speeds before i had hard hangs with this AMD system.
I have no classic NAS but copy files to the other PCs RTL8111H. That card may cause problems of its own.

Just for kicks, I also now run this powershell script upon boot in TaskScheduler:



while ($true) {
       
    $pingtest = test-connection 192.168.1.254 -count 1 -quiet

    if(!$pingtest)
    {
        Write-EventLog -LogName "Application" -Source "AutoNetReset" -EventID 1 -EntryType Warning -Message "Detected network down. Restarting"
        restart-netadapter Wired
    }
    start-sleep 15
}


I've only gone a week now.   Yet to see the message.

Now that i watch this Realtek closer i noticed random IPv6 only packet loss when maxing out the download or copying lots of data to another PC over the local network.
I can see this with PingPlotter to google.com running simultaneously IPv4 and IPv6. 1Gbit inet speed, 1Gbit router, 1Gbit Realtek.
No fancy adapter settings. Default Adapter settings like Qos and other protocols are running.
I have no idea if this was happening before and i also have no idea if this is expected or even matters.

Besides that i didn't have a single hard hang of the RTL8125 since i use the replacement board. The board was changed on this 4th of january running the beta drivber since the 8th.
