X470 Gaming Plus Max - have to disable then enable ethernet adaptor to get internet working properly

My system was working fine, but I decided to upgrade my CPU from a ryzen 3600 to a 5800x.

System Specs:
X470 Gaming Plus Max with latest bios ( 7B79vHB1(Beta version) )
2x16GB DDR4 3600MHz Crucial Ballistix RAM
5700 XT
90+ Gold 800W PSU

So I updated the bios to the latest bios ( 7B79vHB1(Beta version) ), then swapped in the new CPU. Switched on and everything looked great. CPU was recognised, Win 10 booted. Great.
However, I quickly discovered that my internet access was severely compromised. It was mind numbingly slow. So slow most things were timing out, but some pages loaded basic text.
To try to fix it I repaired the LAN drivers, and it all worked fine.
Until I power cycled my PC, and it was slow again. I then uninstalled then reinstalled LAN drivers and it was fine.
Until I power cycled my PC, and it was slow again. So I then disabled then enabled my ethernet adaptor and it was fine.
Until I power cycled my PC, and it was slow again. I’m now out of ideas on how to fix the issue so I don’t have to disable/enable my ethernet adaptor every time I power on.

What about the new bios/cpu or anything could be causing me to have to disable then re-enable my ethernet adaptor every time just to get my internet working correctly, especially since it was working absolutely fine prior to the bios/CPU update.

It's driving me mad, so any help would be greatly appreciated.

Have you done a new clean OS install?

That is literally my last case scenario, and something I want to avoid at all costs.
The thought of having to reinstall everything again, and get everything back how I want it, is not in the slightest bit appealing.
I'd like to think there's some other way around this.

As I'm on a Beta bios, I'm hoping that when the non-beta version is released, that'll solve it, if nothing else does first.

I've also tried clearing my CMOS, then disabling LAN controller in the bios. Rebooting, then going to bios again to enable it, but still same issue persists.

You can try at least OS repair (that will preserve apps. & settings) to see if that will helps.
Else it could be anything at this point, and if its some kind of OS mess, any suggestions will be useless.

Well I guess I've got nothing to lose trying the repair route!

I just don't understand how replacing a CPU can cause this issue!!

Well, I just did an in place Windows 10 install so as to keep all my file and programs, and... not fixed.
Still have the same issue, which makes me think it must be a bios issue? Or is there a possibility that a regular program could be causing this issue? If that's possible, I did not install any new programs immediately prior to or after installing my new CPU. Only thing installed was the new bios, and unfortunately I do not recall whether the ethernet thing occurred after the bios install but before the cpu install, or only after the cpu install.

Can you flash to your prevision BIOS to verify this? [assume if the newest CPU is supported in there]
Do you use ethernet drivers from msi web page for your board?

Yes, I've used the ethernet drivers from the MSI webpage, and also tried the drivers straight from Realte's site.
I think, but could be wrong, that only the latest beta drivers for the x470 gaming plus max board support the 5000 series CPUs. If that's not the case, then I'll gladly try rolling back to a previous bios.
I'll see if I can find out if any older versions support those CPUs.

Looks like I need bios version 7B79vHB to support the 5000 series, as that brings in the AGESA 1.1.0.0 Patch D which I think is what is required for the X470 mobo to work with the ryzen 5000 series.

That bios is the one I've got in beta version, so I don't think I'm able to roll back. I also can't change back to my old CPU as I've since sold it!

For this CPU yes, I trough your new one is 3xxx.

Which Win10 version you use?
Which LAN drivers you have tried?

By slow, how did you measure it?
Have you tested local lan speed to the router 1st?
By power cycle did you mean reboot the computer or shutdown and power on?
If you put it to sleep, then wake up, how is the issue?
Do you have any 3rd party traffic shapers installed?

Can you tried to reset it from cmd with admin rights and follow those commands?
netsh winsock reset
netsh int ip reset
netsh advfirewall reset
ipconfig / flushdns
ipconfig / release
ipconfig / renew

I'll try those suggestions once I've finished work. Thanks.

But to answer the questions:

Which Win10 version you use?
Which LAN drivers you have tried?

By slow, how did you measure it?

By power cycle did you mean reboot the computer or shutdown and power on?

I'm on the latest version of Win10 Pro, all updates installed, and I've tried the LAN drivers from MSI's site and from RealTek's site.
I didn't formally measure how slow it was as I tried to load an internet speed test page, and it wouldn't fully load. Some bits loaded, but it ends up timing out. Same with most websites.
I did not test LAN speed to my router, so I will do that. I don't know how to do it directly to my router, but I do know how to test speed to a Raspberry Pi directly attached to the router using IPERF3.
By power cycle, I do mean shut down and then power on, but I have also tried a restart. I have not tried sleep and wake though, so I will try that.
I'm not sure what you mean by 3rd party traffic shapers, so since I'm not sure what they are, I probably don't have any installed. I do have a Ivacy VPN installed, however I rarely connect through it.

Ok, I've tested my local LAN now.

Using iperf3 to communicate with the Pi attached to the router, I did it several times. 1st time it timed out completely. 2-4th time, each time the first transfer was near full speed, the second transfer was about 20%, then all the remaining transfers were zero. So it does appear that my local LAN connection is compromised as well, which I guess suggests issues with the ethernet port, rather than specifically the internet connection.

Sleep then wake - This is possibly a separate issue, but I can't seem to get my computer to wake once it is in sleep mode! Keyboard presses, mouse movement don't do anything. Hitting the power button appears to make it completely restart, so I can't comment on what happens after the computer sleeps.

I also ran all the cmd lines with admin rights.
Still no difference, the problem is still here.

To work around the issue, I've written myself a little .bat file to disable then enable the ethernet adaptor, and have it set to run after every start up. Saves me from having to manually do it, but still frustrating that it has to be done!

Just had my computer go to a sleep through inactivity, as opposed to me clicking "power" -> "sleep", and the mouse movement woke it up, and once it woke up, the ethernet wasn't working again. Had to disable then enable the adaptor to get it working.

So yes, it seems my comp going to sleep also causes the issue.

Do you still have the old CPU to try the older BIOS that was working fine before?
