Greetings,
If not already done, perform a BIOS reset to ensure all settings in the new BIOS appear as expected. To protect yourself, its a good idea to have a back up of your data whenever significant changes are made.
Are you using the onboard LAN? This may not be supported if using a add-on NIC.
By chance do you have "ErP" enabled? If so, this disables WoL. If ErP is not enabled, verify the setting hasn't been moved in the later BIOS rev. It should be under the Power Management heading.
Since I don't have this board, I can only go by what I see in the manual, which may be different than the BIOS you have. The setting is not listed in the manual except under ErP where it states enabling that, disables power on wake events such as WoL.
This failing, open a ticket with support.
