Does Wifi connection support wake on Lan? Perplexed I think this may be a stupid question but.....

It's not *that* stupid a question, because for wired wake on lan something needs to be listening and still on, waiting for the magic packet to tell it to wake the machine up.

But no, it doesn't.

bah damn that sucks. me and my friend were talking about this yesterday, having a wireless device that we can power our pc's on with using a wi-fi network.

You could do it with a wireless router and attach it to the device with a cable Smiley

Maybe there is an option in Windows to allow the device to bring the computer out of S3? I've got a computer with onboard LAN which I can only wake up after hibernate, as it only supports WOL on S3.

Right click My Computer -> Manage -> Device Manager -> Network adapters -> Properties of the device -> Power management -> Check both "Allow this device to bring the computer out of standby" and "Only allow management stations to bring the computer out of standby" (else every activity would bring the computer out of sleep mode)

I found this website a good source of information regarding the topic:
http://www.depicus.com/wake-on-lan/what-is-wake-on-lan.aspx

For browsers:

For PocketPC:

To allow the computer to hibernate through a remote desktop session you need to use a batch file with:
rundll32 powrprof.dll,SetSuspendState

Good luck,
Peter

Actually, I think all PCI devices in theory can wake up computers. However, because wireless LAN cards don't have external power supply like the wired LAN(you can see LED switched on when plug a connected LAN cable to it), I doubt it can react to WOL signals when the computer is off.

It works,

don't ask me how.

It just does.

Hello RossJ,

I'm not sure, I'm in Moreton, where are you?

So you have tried it then and it worked? Did you do anything special?

I'm building a car PC and I want to wake it up via wifr, to transfer files from my PC in the house (such as video and MP3's) to the carPC, next time you jump in the car your content is with you.

So for example I'll have my PC download the latest Podcasts and then ransfer them to the car.

My to concerns were How to wake it up and Power (don't want to drian the car battery) but I was thinking of using a dedicated battery for the car PC which could be charged while on the move....

Just tried it with a D-Link AP 2000AP+ and a Dlink Wifi Card, I made sure in the bios it had wake on PCI, couldn't see wake on Lan.....

I'll double check everthing and see what happens....

Yes. "wake on PCI" is the option needed for "wake on LAN", as the LAN card is normally on the PCI bus.

That is a dang good idea. Good luck with that.

Thanks!!! Still can't get it to work.... Sad

Does anyone know of any good wol utilites I could try? I've tried a couple searching the internet, but they don't seem to want to play... Sad

Does the AP (Access Point) need to support WOL-over WiFi? Perplexed [C]

Thanks.....

The DualCor cPC will do the job nicely.

You'll need to add the Wi-Fi card, the cPC runs Windows Mobile and can wake-up Windows XP when needed.

That looks like it'd look kinda neat embedded in the dashboard of your car.. where did I put that hacksaw...

When you say it will wake up Windows XP, I think thats the wrong way round.....to how I want it to work.

Yep

This car-audio stuff is already out there. I know that the guys from carotechnology.com worked on this a while a go and are bringing this to the market. I believe they used a special kind of PC and orinoco cards. Don't know about any hardware modifications...

I believe that any solution to this will be based on proprietary hardware/software and at present moment, there is no wake-on-wifi solution widely available. The mani reason is that wifi card needs constant power source in order to be able to transmit and receive and that wifi card chipset needs to be aware of so called wake packets. Also, wireless configuration (SSID, WPA secret etc.) is handled by running OS (Windows Zero Configuration Service) or client application (like Atheros Client Utility). Therefore as soon as you shutdown/hibernate/standby your system, your wifi gets 1) stripped of power necessary to connect to AP, 2) loses configuration about to which AP/network to connect...

With WIFI/Ethernet bridge, the solution can work, given some conditions, like the Wifi/Ethbridge must bridge all frames unconditionally. Remote wake over Internet is not possible for standard scenarios, because WOL capability is Ethernet frame based, no IP based. So you cannot send Magic Packet over routed network. However, you could have in your target network one host, that is always on (eg. server) with application installed that is able to wake up PCs remotely. You just need to remotelly connect that host, but it is quite easy to achieve with either RDP or SSH (based on you taste Smiley

I was looking to see how this worked because, I am using WHS and had WOL enabled on my laptop throught the WHS console interface on the laptop. If the laptop is hibernation it wakes on lan to do the nightly backups via wifi. I have no clue how its doing it since in hibernation it should not have power running through it yet it not only wakes it but wakes me when it starts up. I know its in hibernation cuz I dont like sleep mode since it uses power while in it draining my battery when not pluged in. I normally have my laptop plugged in and have not tesetd it to see if it will WOL via wifi without the powerplug in. I am running vista and have no special setup besides WHS.

No it doesn't. It wakes the laptop out of sleep at the start of the scheduled backup period, not because of a wake on lan ping. You've been able to do this for scheduled tasks for some time - if you use the XP task scheduler for example there's a Wake my Computer option.
