Following on discussions from the other thread, i went ahead and installed WOL and although it has picked up my mac book, server, pc etc, using the wake up function or sleep doesn't seem to work. Ive turned on my pc and tried to put it to sleep but nothing happenings. Ive shut down my server and tried waking it up but again, nothing happens??
 
I've very little experience with WOL but I remember reading somewhere that you have to set the network card of the machine you want to turn on remotely to accept WOL or magic packets? I think you do need to activate an option somewhere on the destination network card to allow that PC to be turned on over the network.

Check the NIC properties on the machine you are trying to wakeup and make sure it has WOL enabled. WOL software will find all machines on your LAN, regardless of whether WOL is actually enabled iirc.

In windows, you can check by going to properties of the NIC in device manager and then going to advanced tab. There may even be extra tabs, really depends on the NIC. Also, some machines with built in NICs may have an appropriate setting in the BIOS.

Of course...let me check it out

Thanks guys

One other thing while im doing that. i can work my server perfectly form my mac via remote desktop but i just tried to log into my pc with no joy. I have already enabled the desktop to be controlled by remote software so im not sure why i can't. Ive tried connecting by using both the pc network name as well as the ip address of it??

I've just checked on my desktop running W7 and it looks like:

Just to clarify things, you are trying to connect to your PC, not your server, from your Mac?

Are you getting any error messages? Is the firewall on your PC set up to allow such incoming connections?
 
I can connect to my server via RD fine, im just trying to enable the WOL function.

Staying at the PC for the mean time, i have gone into NIC settings and under power management it says only allow a magic packet to wake the computer.
Under advanced, its shows

wake on magic packet: Enabled
Wake on pattern match: Enabled
WakeOnLAN from powerOff: Enabled

Turn off any firewalls on the windows box and check again. I can't recall if it is turned on or off by default for "home/work connections" (assuming it is W7 or similar).

Yes, but I meant that the text and details vary by NIC and driver. For instance, here is 2 of mine on same machine (No idea what is going on with the realtek NIC, maybe it's settings are in BIOS as it is onboard):

If you just enabled those settings, give the machine a reboot, make sure they "stick" and then shutdown and send a new magic packet from WOL.

Of course. :) I was just trying to illustrate where the settings would be. I can imagine that even on W7 the settings could be in a difference place or be worded differently with different NICs. :)
 
Hmmm, maybe its something to do with how i have my pc connected to my network.

After moving my router into a cupboard along with the server, i have resorted back to my netgear WNA 3100 wireless adapter. Going into the WNA3100 under device manager and power management, the option for "Allow this device to wake the computer" isnt available.
When i go to advanced, wake-up-mode, there is a list of options and mine is set at Magic & Wake up frame. Would this have anything to do with it???

Other options from the drop down include:
Magic packet
MagicPkt & Linkloss
None
Wake up frame
Wakeup pKT & linkloss

Now I am really confused, if the destination machine is connected via WIFI you won't be able to use WOL on it.

Is the NIC built in? What model/brand is it? Is there any BIOS settings related to WOL (probably only relevant if the NIC is built in).

As long as the actual server/pc is connected via Ethernet to a router/hub, it shouldn't matter how you are connected to that router/hub.

i.e. My server is connected via ethernet to the router and my MBP is connected to the router via wifi (sometimes ethernet when I want faster speeds for file transfer)

Edit: in case it is the WOL software, here is a screenshot of mine:

Could it be that the WNA 3100 can't transmit or pass on WOL packets? Are you able to wire your PC direct to the router? Perhaps you need to bypass the wireless adapter?

Sorry mate, i should have mentioned all this at the beginning. I have the server connected directly into my router so once i go to do that i shouldn't have a problem.

My PC however, is now connected via a wifi adapter. Connecting it via ethernet is no longer an option. The PC doesn't get a lot of use by me any more but i thought it would still be good to use this function.

So it probably is the adapter causing the problem then.

Might try and change the setting to Magic packet opposed to magic & wakeup frame??

OK, don't waste any more time trying to WOL the PC that is using wifi, it won't work ;) . Simple reason, a NIC can have power when the machine is "off". USB ports (i.e. your wifi adaptor) don't.

Now, your server. What sort of NIC, built in or not and any WOL BIOS options? I guess you are going to have to hook up a monitor to check the BIOS or use the iLO if it is configured :) The main reason I can't be bothered to check what BIOS options I am referring to is that my microserver has no monitor connected :)

Agreed, the PC is least of my worries right now.

Ok, the Server:

The NIC is a HP NC112i. Ive ben looking at the server for the last 5mins. like you, i dont have a monitor handy so i cant check the BIOS but i think i may have to as when i selected the option on the NIC to "Allow this device to wake the computer" under power management tab, it didnt do anything.

Does WOL work when the machine is shut down completely?? I dont see an option to put the server into sleep mode?

Yes, it works when the machine is shut down, that's how I use mine. Depending on your OS, you may not even see the Sleep command, especially a Server OS. If it was a desktop OS, I believe WOl can also wake sleeping machines if they support S3 Sleep or something like that that I don't know too much about!!!

On a day to day basis, my Server is off. When I want to stream media to it from my Mac, I send a WOL command. When I am finished I RDP and shut it down.

I think as it is an embedded NIC you will need to go into the BIOS, probably a setting very similar to what the guy above me has posted

i have it running Server 08 R2.

I couldn't use the above file on my mac but let leave it for tonight, tomorrow i will hook up the monitor etc and check the BIOS. As long as i can do that i'll be happy enough. Shame about the PC, not to worry. Come October im going to be starting my server studies so i intend to have server running full time and implementing active directory etc and having the server as the main storage.

For now though, thanks for all your help, really appreciate it. Check back in tomorrow :D
 
Ok, so i hooked up the monitor to the server and enabled wake on LAN for NIC 1 (2 altogether) but its still not switching the machine on, or putting it to sleep.

Would it be anything to do with how i have my hub setup? Do i need to create a LAN or is it already created?
 
I find with my machines that they will not WOL unless first shutdown down from a known good state and left connected to the mains.

If I remove power and then reconnect I can't get WOL working on all but 1 machines (the oldest). That's trying both on board NIC's and added NIC's, once the power is removed WOL will not work.
