Move to a PCI or PCIe card to solve this one. I haven't heard anyone fix this on USB adapters.
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.
