Wake on LAN (from shutdown)

[scienceman78]

I'm currently have a wifi card that supports wake from LAN, but it only allows for sleep. I want to get a new card that allows wake from SHUTDOWN, but I can't seem to find one. I know they're out there, can any one give me some advice? Thanks.

To "Wake on LAN" from a shutdown state requires re-configuring the motherboard BIOS I would have thought.

Look for something like "Power On By PCIe Devices" and enable it.

There likely is no "WiFi" card that can do this. The WoL standard only defines ethernet. Any form of Wake on Wireless would be some non standard thing...maybe they will at some time add it to the 802.11 standards but I have not seen it talked about.

A WiFi connection is massively more complex than ethernet. You have things like encryption keys that constantly change, data re transmission and many more. In many cases the WiFi chip is dependent on the main CPU for parts of its functionality. This would mean you must keep you main CPU and memory active. With ethernet it is just a single chip that doing the work.

You in effect are going to have to leave some device powered on to turn your computer on. The simplest I have seen is a feature in Asus (I think) routers that let you log into the router and have it send a real WoL packet to the ethernet port of your PC. Then again if your PC was hooked to the router with ethernet you could use normal wol packets.

The other possibility is to use a external bridge. This is in effect a wireless nic that hooks to your ethernet. You of course would have to leave the bridge devices powered on all the time. This is a very non standard thing to do but the WoL packets will pass over the wireless to the ethernet but it might not on all bridge devices because of the way broadcast packets are handled.

Not sure why you even want to do this. PC boots extremely fast from completely off if you install the OS to a SSD drive. If you think you can do this from outside your house you attempting to do another things that is not WoL. There is no such thing as Wake on WAN either. If this was your plan then go with the router solution since that can be run from a external location.
