Inconsistent Wake on LAN

Question

Hi,

We have multiple machines across multiple rooms on site.

I am trying to get Wake on LAN working at an acceptable level, via MECM.

In one room, if I send the 'Wake Up' notification via MECM, it will wake up all machines first time. Another room though, it would work first time, but then show inconsistencies after that i.e. sometimes five would wake up, 3 the next time, 14 another time.

We have Wake on LAN enabled for the site, using client notification channel on MECM.

Settings changed:

• Send 'Magic Packets' in network config.
• Wake on LAN enabled in network config.
• Disabled Fast Startup.
• BIOS Wake on LAN enabled.
• These are HP machines, so have this setting in registry setup : AllowWakeupFromS5=1
• Have at least three machines on to act as Guardian Machines (https://learn.microsoft.com/en-us/mem/configmgr/core/clients/deploy/plan/plan-wake-up-clients)

Are there any other settings I can changed to improve the rate? Am I missing something with how this works?

Thank you!
