Hello,
I have Realteak RT8811AU network adapter connected via USB to my desktop computer for wifi connections. I get greater network speed but however, I am unable to set it to wake on lan. I have a ASUS P5Q Pro LGA 775 motherboard and on my bios I have setup to wave via PCIe and PCI devices(basically every device option I have). However, I go to the 'Power Management' or the Realteak adapter via 'Device Manager' I see no way effect of setting the 'Allow this device to wake the computer' option.In order to check this option I have to check 'Allow this computer to turn off this device' option which in some forums they have been saying is the reason WOL doesn't work because the computer turns off the network adapter. If I select the 'Allow this computer to turn off this device' option and then select the 'Allow this device to wake the computer' option and deselect the 'Allow this computer to turn off this device' option that also doesn't work. And there is no way to select the 'Only allow a magic packet to wake the computer'. Also I have set the setting to have the computer not be able to turn off the usb devices. I have read several forum posts but unable to solve this problem.

Part of your problem is there Wake on LAN does not mean Wake on "Wireless" lan. Wireless is massively more complex than ethernet. Even if you ignore the encryption there are constant messages being send. Ethernet pretty much just sits there are watches for a particular data but sends nothing.

I suppose they could make a Wake on "wireless" but it would need to be a function the wireless chipset did. It would still require a lot more power than a ethernet port.

They do make devices that turn the physical power on. You could set the PC to boot at power on if your motherboard has that option.
WOL is set in BIOS because it turns on a computer that is turned off (in the olden days we ran a wire from our network card directly to the motherboard to do this). While many computer will now provide power to USB while the computer is off, the data that comes in from the USB port is interpreted by the CPU. Your CPU is turned off. So, while connected to USB, you will not be able to start a computer remotely. If you were using a PCI or PCIe card and the adapter supported WoWLAN, then maybe it will work ... though I read a lot of people having issues with it.
