Ethernet speed issue

I noticed an annoying issue while downloading games, the motherboard's Realtek ethernet speed is inconsistent, sometimes it's 1Gbps sometimes it's 100Mbps. Once it picks a speed it stays that way and works, so it shows 1Gbps works, the issue is just that sometimes it chooses 100Mbps instead.

Context

I know the rest of the network is fine because the old PC was always 1Gbps, same cable and everything, only thing that changed is the PC.
I'm on YouFibre 150 and thinking of going to 500, so want to get this fixed.


Driver

I have the latest driver from the ASUS website:

Realtek LAN Driver V1125.21.903.2024 for Windows 11 64-bit---(WHQL).
Version 1125.21.903.2024
27.45 MB
2024/12/09

I tried downloading these files from Realtek:
  • Win11 Auto Installation Program (NetAdapterCx)
  • Win10/Win11 Auto Installation Program (NDIS)
but they both are a zip which contains an exe which when double-clicked nothing happens.

Edit: That was Microsoft trying to limit me to only installing apps from the Store, which became obvious when I tried to install Samsung Magician instead. I installed the Realtek NetAdapterCx file, which installed loads of drivers and resulted in my driver being updated. Although I'm at 100Mbps now so that probably hasn't fixed it.

Settings tried

Speed & duplex is set to auto-negotiate speed. If I select 1Gbps it just takes longer to negotiate, the result is still randomly either 1Gbps or 100Mbps.
Edit: I'll have to test this again with the new driver.

I disabled the below eco features as per this website, but that hasn't fixed it.

Ensure that the following settings are set to “Disabled”: “Energy-Efficient Ethernet,” “Gigabit Lite,” “Green Ethernet,” and “Power Saving Mode.”

Any other suggestions?

@throwaway4372 Have you made sure your bios is fully up to date as this is the on board NIC?

Have you checked your bios for any power saving settings as well?

All I did in the bios was: update bios, set defaults, set date/time, enable xmp
Are there any other settings that come to mind I should check?
I'd prefer to only touch the bios if there's a specific thing I need to change.
As far as I know I have the latest on board nic driver (see my earlier post), the realtek website sux so it's hard to know for sure.

There was nothing in the bios, and I've exhausted my list of things to try, and wasted far too long researching about it.

So it's time to throw money at it, new cable on the way, I needed an extra cable anyway to connect the old pc. If that doesn't help I guess I'll have to get another adapter, looks like usb ones available for a tenner so could try that. Anyone know if they're good enough?
 
Seems like it does run at 1Gbps if I bypass the switch between the patch panel and the router, so it's either the switch or one of the two cables which this Realtek 2.5G hates but my previous PC was fine with.

Shame the eero only has 1 ethernet port. If it had 2 I could live without the switch entirely.
