Wake on LAN info needed please

dangerousmouse · 1 Jul 2006 at 13:18

ok, i've looked around on google results etc... but it all seems a bit vague still. so if anybody is using this feature, or can help answer some questions it would be appreciated.

does wake on lan work if the computer is properly switched off, or is it just when on standby/hibernate?

how do i activate it. not setting it to on in bios, but actually boot the computer?

if i were at my parents, could i send this 'magic packet' and startup my computer (have an always on connectio nwith my modem)?

thanks, there may be more to follow (depending on the answers from these questions).

I'm guessing what you actually mean is WOW wake on wan?

I.e. send a magic packet over the internet to your IP address and have it wake up you machine.

Rather than WOL which is used in LAN's, in the lan scenario it works really easily...

From the internet i managed to get it to work, but is a real pain if you are not up on networking; basically you create a packet that has the MAC address of the machine you want to awaken (can be from cold), send it to the IP of your router, which then needs to broadcast this to your LAN. I will see if i can find the appropriate info for you. The packet needs to be forwarded to the broadcast address for your 'network' so on say 192.168.0.x with a subnet of 255.255.255.0 that would be 192.168.0.255; you will need to to some more reading on this though....Over the internet i way more complicated that over lan....

Just found the page that i used, there is a couple of apps on there to Sniff for the packet, to make sure its getting throught to the machine. You will not get it when windows is booted unless your firewall allows it;

Hope this helps;

There should be a program or a good explanation on how you do it with the network card or motherboard you get, i always wondered if this was just a gimmick as i never could get it to work myself and it was hard to find any good information on how to do it, a bit silly i say.

that sounds more like it, wake on WAN. hmmm. i have found a couple of sites that will send a magic packet for you, as long as you provide the correct details (ip, subnet mask, port number). but how od i got about doing it myself, can it just be sent from command prompt to the ip address, thus booting the other pc?

and just to confirm i have understood this correctly, the network adapter is still actively powered even though the pc is actually switched off completely. when the magic packet is recieved, this activates the 'wake' command from the network adapter to the rest of the pc?

so, if the above is correct, this wont work with a wireless network will it? i am under the impression it will only work if i have the router wired to the pc with rj-45?

thanks.

No, it won't work for wireless.

Incorrect!!

This Wireless supports WOL:

Some PCI wireless cards work, but the USB ones dont.

But the majority don't (having a look around that Proxim's about the only one), so your point is?

He wet his pants to point out a pro overlooked something.

WOL (Wake On Lan) needs to be enabled in your BIOS, also if at your home you're using a router with and SPI Firewall you'll need to enable pass through.

Not really familiar with Wake On WAN.

I've a WRT54G with a custom firmware behind my FW which supports WOL.

My point is that your blanket statement that it does not work with WiFi is incorrect.

you might want to have a look at this:

Came accross it while looking for WOL software for my PPC (so I can be extra lazy on a saturday and turn my PC on from my bed before i actually go downstairs)
