I have an Alienware Area 51 R2, with BIOS version A14. How do I enable wake on LAN (WOL) in the BIOS? I can't find the setting anywhere.
According to a post from randye007 on a Dell forum and a Dell knowledge base article, you need to enter power options and disable "Deep Sleep". Once that's disabled, the option to enable Wake on LAN will appear.
(Note: I ask and answer this question here because it was very difficult to find these pages.)
EDIT: I have determined that the following is no longer required, not sure why (perhaps PEBCAK or inexperience with WOL?). Original answer below for posterity & educational purposes.
In addition to Kyle's answer I also needed to in the BIOS go to:
Advanced > Integrated Devices > Pxe Option > UEFI PXE Driver Change Disabled to Enabled
The defaults of
Enabled for Ipv4 and Ipv6, just worked for me.
