Wake on LAN doesn't work from shutdown on my Asrock B450 Pro4. However, it does work when in sleep mode.

Here are my settings:

I have the same problem with my Asrock B450 Pro4. Wake On Lan works from sleep but not from shutdown.

Settings seem OK:

UEFI
Bios version: 3.40
PCIE Devices power ON - enabled

Windows
Power Options - Advanced settings - PCI Express Link State Power Management - Moderate
Realtec driver - Power Management - Allow the computer to turn off this device to save power enabled
Realtec driver - Power Management - Allow this device to wake the computer - enabled
Realtec driver - Advanced - Shutdown wake on lan enabled
Realtec driver - Advanced - Magic packet wake on lan enabled

It seems to be a driver or BIOS issue since it works from sleep mode. Does the 3.50 bios fix this?

There's a post on Reddit as well with the same issue: https://www.reddit.com/r/buildapc/comments/bdnsn8/wake_on_lan_on_asrock_b450_pro4_not_working/

Asrock, any help? I saw that you answered the exact settings to use with other boards.

Thanks!
