I do have hardware acceleration enabled.
I haven't seen those errors in the logs or lan2 taking it's own Mac address.
I think it is related to power management on the ethernet chip when the computer is sleeping. I have other computers with msi motherboards and realtek nics and they work well.
For example the wake on lan app I have on three phones has online status checks which check ports and ping the nics. Only when I have the wake on lan app does the x870e tomahawk randomly turn on without even pressing the device to wake it. Other devices don't do this.
I'm assuming other devices have the wake on pattern march enabled and so I disabled it in my pc and then disabled the online status checks on my phone wol app too.
So far yet I haven't been disconnected from the internet again, I think maybe next thing I will try is turn off wake on lan from the bios if the internet disconnects again.
One of the recent times when the internet got disconnected, I did turn the MSI PC back on from sleep and it was connected fine with an IP address.
