I found LAN CARD that I use was not good with DELL PC. I changed LAN CARD and WOL works fine.
Hi I installed 10Gb PCIE ethernet card to OPTIPLEX 7070 SFF I want to use Wake up on LAN using PCIE ethernet card not using integrated NIC.  I am checking UEFI setting but I could not find any option for that.  PCIE ethernet card is power off until OS booting. After OS booting, card works fine.  I can use WOL with integrated NIC with no problem.  Does anyone has tips for me ?
