Wake On Lan

Discussion in 'Mac OS X Lion (10.7)' started by metec, Apr 17, 2011.

    It seems that Lion doesn't fully wake the computer with WOL. When I send a WOL packet, the keyboard lights up but the screen does not come on. This would be fine except that I can't connect using VNC. I'd have to press a button on the keyboard or click the mouse/pad until the screen comes on and then I can connect. This makes WOL useless.

    This also seems to be the case when you press a keyboard button. The keyboard lights up but the screen does not turn on. If a press something again, the screen will come on. If I click the mouse instead, the screen comes on right away.

    Has anyone been able to use WOL?

    I've noticed the same thing and this behavior is preferable for me. Hopefully they'll add a preference (most likely not through the GUI) for the desired behavior.

    Just curious, how is something not turning on, when you explicitly press a key or send a WOL packet preferable?
  4. macrumors newbie

    Because when you send a WOL packet you are not in front of your computer ( you are probably going to use SSH or VNC), so you don't need the screen to turn on. :)
  5. macrumors regular

    But the OP said you can't connect via VNC unless you press a key on the physical keyboard.
  6. macrumors newbie

    I didn't read that, sorry.
    Then it is probably a bug

    Just installed OS X Lion on my new iMac, and I can't seem to Wake my iMac using Logmein Ignition either.
    Also waking the iMac, for streaming of e.g. video (using Airvideo from my iPad/iPhone) doesn't work.

    Any updates on this problem yet? (Didn't have any problems waking my iMac under Snow Leopard).

    Any solutions yet?

    I'm having the same problem with iTeleport and Air Video on Lion.

    While I was on Snow Leopard, I could wake my iMac from sleep (when it automatically fell asleep after the set duration of time) over WiFi and 3G with iTeleport. When my iMac was manually put to sleep, this would not work. However, I found a workaround for this - opening the Air Video app (on WiFi or 3G) would wake the computer, the screen would come on, and then I could close Air Video and open iTeleport and connect with VNC.

    Since installing Lion, I can't wake my iMac over WiFi or 3G whether is was put to sleep manually or automatically. I can hear it turn on when I try to wake it over WiFi, but the screen stays dark and it won't connect. I have to press a key on the keyboard. After I do that, the screen turns on and I can see iTeleport Connect connect after about two seconds. It's not reachable at all over 3G when it's asleep. So, it's pretty useless right now.

    I do remember that Snow Leopard broke remote login in iTeleport (Jaadu VNC at the time) when it was first released. Jaadu released an update that fixed it about two weeks after Snow Leopard was released. Hopefully, they'll be this fast this time.

    I'm not using WOL or port forwarding, just the standard iTeleport easy setup, but that always worked fine on Snow Leopard.

    Strange. It seems to be some sort of bug then?

    Perhaps Bonjour doesn't give the proper signals to wake the iMac under Lion (I believe Bonjour was the service that would wake the Mac under Snow Leopard??).
    Or this new 'Low Power Wake' for OSX Lion doesn't work properly (not enough power ;) ).

    I'll fiddle around with it some more this evening.

    Yeah, I think it has something to do with the screen not coming on. I disabled and reenabled internet access in Air Video and finally got it working. I can wake it enough to play videos over 3G now, but the screen doesn't come on and I still can't access the computer with VNC if it's sleeping.
  12. macrumors member

    Yeah, after a couple of tries, from my iPhone/iPad, to connect AirVideo it suddeny connects to my iMac (thus waking up the iMac).
    After that I can connect to my iMac, using Logmein.
    So it seems it's just Logmein that can't wake up the iMac......?
  13. macrumors regular

    Correct. As far as I know, none of the WOL or VNC apps can wake a Mac running OS X Lion.

    Your screen doesn't come on when you access the videos over 3G with Air Video, right? Mine doesn't. It does play the videos, though.
  14. macrumors member

    Indeed, screen stays dark whilst streaming AirVideo.
    Guess we'll have to wait for a OSX Lion patch?!
  15. macrumors regular

    I sent an email to iTeleport Support and they sent me a link for a beta version of iTeleport (5.1.1). This update seems to have fixed the problem. I can now connect via VNC over 3G when the iMac was sleeping. I still have to use Air Video (works like a WOL app) to wake it first, but I had to do that on Snow Leopard as well.

    New feature

    Apple has presented this as a new feature, called "Low power wake". It is supposed to save power as it only activates filesharing and such. There appears to be some way to wake the system further up to normal power state, but i have not yet found any reference to this functionality...

    I'm still not able to remotely access my Mac with teamviewer after the packet was sent to the Mac running lion which defeats the whole purpose for myself. I guess I'm sticking with sl

    If I leave my Air in Sleep, but leave the lid open, I can wake it with the Remote App, and then Air Video (or whatever) will work... (in Lion, 2010 Air)
  19. macrumors member

    I'm having almost the opposite of this issue on my 2009 iMac. Even when I manually choose sleep from the apple menu, it doesn't really go to sleep. The screen turns off and after a few seconds I can here the sound of hard drive spinning down as expected. However, about two seconds later, it makes the sound it usually does when waking up from sleep, without actually turning on the screen. I can even access Air Video Server and Plex while it's sleep. To make it even weirder, Apple's own Remote app can't access it when it's supposedly sleep.

  21. macrumors newbie

    This issue may be related to the low-power wake introduced in Lion, but if low-power wake does not allow things such as VNC or printer sharing (the problem I'm having) to work, then a fix is still needed.

    With my Mac Mini (Lion), even with "Wake for network access" checked in the Energy Saver preferences, the ethernet seems to go to sleep completely with the computer, not even allowing the low power wake. I say "completely" because when manually waking up the computer, there is no internet connection in Safari for a few seconds while the network is reestablished.

    This prevents backing up my laptop to the shared hard drive as well as printing and VNC. Anyone find a solution that makes Lion wake up fully?

    Anyone notice any improvements since the 10.7.1 update?
  23. macrumors 6502

    I am still having issues with 10.7.1... I can not get Logmein or RealVNC (4.6.3) to work :confused:
  24. macrumors member

    I still have issues too. Unable to wake my iMac using LogMeIn.
    Need to wake my iMac using AirVideo, after which I can connect using LogMeIn.

    Wake On Lan

    Same problem.. my MBP (Lion 10.7.1) no longer sees my networked iMac (SL) after the iMac goes in to sleep. This never happened before in upgraded the MBP to Lion - I could still immediately see the iMac and shre files, screen etc..it's a pain... Apple please get this fixed.
