 Have I posted this on the wrong forum?
Could anyone point me into the right direction, please?
TIA

Posting a bug report in this thread usually means you have to hope that a Kodi developer reads it and is interested enough to work on a fix with no further prompting. This does sometimes happen.

Alternatively, you can open an issue on the Kodi Github, which tends to make it a little more "official", but still depends on someone taking an interest.

Providing as much information as possible usually increases the chance of a fix, particularly if you are able to say "it worked in build #XXYY, but is not working in build #XXYY+1" as then developers can zero-in on a specific build and see what changed.

If this WOL feature has never worked on this hardware, then it's likely to be a very old bug, or possibly a driver issue.
