Wake On Lan does not function despite all settings being correct and enabled

Question

Within my own network, I am able to remote into the target machine, but not able to wake it from standby/sleep.

I note that I have tried all the usual troubleshooting (have read all the how-to's, which are largely all the same! and videos), and this is a last resort.

To rule things out, for those offering support, so we're not coving the same ground - I have already:

• made sure BIOS WOL is enabled
• made sure fast boot is disabled
• I have got the correct network adapter settings (power management has WOL enabled with magic packet etc.)
• I have got the correct network adapter advanced settings (all the wake and link and UDP options are enabled
• I have made sure the power settings for the system (power link state management is off)
• I have also checked in regedit to make sure its accurate
• even tried rolling back network adapter driver to a much earlier version (1.0.4.1 or something) as reports it worked (it did not)

I have read reports of WOL working with this hardware when using Linux, which suggests it's a Windows issue. But that's anecdotal as I'm not switching to linux.

Also looked at this thread, which did nothing for me too.

All drivers are up to-to-date - have uninstalled and re-installed with the latest to be sure. Also tried using Microsoft vs. Asus (I have the ROG Strix B660-I board which has the I225-V NIC).
