Q: No Wake-on-LAN possible since updating to ML

Hi everybody,

 

since updating from OS X 10.7 to 10.8 (clean install), Wake-on-LAN does not work anymore. Setup: Mac mini (Early 2011) connected to Time Capsule (2nd gen) via devolo dLAN. Mac mini goes to sleep after 30 minutes and eventually disappears from the network. Sending Wake-On-LAN packets or using Back To My Mac fail, it simply won't wake up.

 

Wake-on-LAN worked smoothly under 10.7 after some problems. Any ideas?

 

Thanks and regards

 

Steffen

    Yea you are correct.  I thought it helped at first, but it ended up not being a solution.  I agree with Randall Jenkins, if you are able, everyone should submit a bug report. 

     

    I also suspect it has something to do with the new Power Nap feature.  They must have rewritten the "wake on" feature in OSX

    i'm running a wired LAN connection for my iMac and had similar issues to everyone on this thread (although i did experience this on Wi-Fi as well).   After reviewing a number of different threads over different OS versions, I tried the following and it has given me success today, although preliminary it is much better than I have been at any point in the past.

     

    In the network settings, people had mentioned re-arranging the network connections in order (ie. put Ethernet or Wi-Fi on top) .   That suggestion did not work for me.   What I did change here was the locations.   Typically you would see Automatic and maybe Home.    I added a brand new one and switched to that location.   I then deleted the previous locations, so just the new one remained.    When I activated, my connection was dropped and it re-established getting a new IP address, etc from DHCP.

     

    What makes me interested here is that when the new profile was created instead of using an old one, it added a new type of network adapter that was Bluetooth related in addtion to the existing ones.  

     

    Since that change, the iMac finally allowed network traffic when asleep (remote MacPro, Apple TV etc..)   I reduced my sleep time to 15 minutes and have tried a few times today and it has been waking up consistently on LAN traffic.  I've tested by putting to sleep via VNC, seeing the iTunes connection disconnect and then reestablish when I selected it again.    I will let this run for a while and see.   Hope this helps someone out.  At best a workaround,  but I'll take it considering the frustration I've had with this for a while.

    Thanks for the info, I have tried this and managed to get an iMac to wake on several occasions over a 16 hour period from both a MacBook Pro and iPad and thought I had cracked it.  Alas shortly after I thought this had worked it vanished from the network again. If you can let us know how you get on testing your setup that would be helpful.  I will test it again as I may have missed something and post back the result.

    Thanks from me, too. Unfortunately this hint didn't work better. I put all my hopes on the next ML bugfix, hoping it comes earlier than we all expect it .

     

    nice weekend to all of you....

    unfortunately mine has dropped again and won't wake up.. After my previous test, i deleted everything but the ethernet connection.   i think what actually made it work was the fact that I didn't realize that Wi-Fi was somehow simulataneously enabled at the same time as my Ethernet connection.  I think the wake-up is happening through the wi-fi side.. with it reenabled it is waking up again.   Definitely bugs on pure Ethernet side on this.

    Just to add to the numbers here. I upgraded from Lion (which had been a clean install on a brand new HD installed by an Apple authorized service center on my 2008 iMac) to ML 48 hours ago. Now it appears that "Wake for Network Access" isn't working. That setting was in place before the upgrade and afterwards, has never been unchecked.

     

    In my case, I don' t have anything fancy, just my iMac and my home wifi network via a 2011 Airport Extreme base station. Until ML, when I woke up my iMac in the morning, if I'd left my browser open, I'd find all my new emails in the Gmail inbox, all the overnight notices loaded in Facebook, etc. And if I'd left a download or upload going the night before, it would be completed.

     

    Not so under ML. By the way, the wi-fi network keeps working just fine when the iMac is asleep - I've confirmed that via other devices including my Kindle Fire tablet and my Rokus. No problem connecting them to the internet by wi-fi.

     

    But the iMac sleeps regardless if an upload or download is happening, and has no internet connectivity until I wake it up again.

     

    I've specifically been using Safari so as not to confuse the issue with "3rd party apps." I've been uploading some photo files to a secured area my online photo site, which I do occasionally as backup. That's 4 or 5 GB at a session, and it makes sense to let that run while my iMac and wi-fi network are otherwise idle. But after repeated attempts and experiments, it's clear that when the iMac is scheduled to sleep, it just does, and stops its internet connectivity. I've come back at least twice after 2 hours, and also once after 8+ hours, to find the upload had stopped when the iMac went to sleep.

     

    I've set the preferences to have the "computer sleep" at 1 hour, and as noted the "wake for internet access" preference has always been checked.

     

    I have performed SMC and PRAM resets. This has not solved the problem. I will file a bug report (thanks to those who posted the link).

     

    I really don't want to set the "computer sleep" to "never," since my iMac does get really warm when running and I worry about the wear and tear of all that heat on the hardware.

     

    I'm not a techie, just a fairly expert computer user. I've had a Mac for 4 years and have enjoyed its reliablity. I hope this isn't a portent that I'm in for a PC-like future with my Mac: having to start tinkering under the hood just to do very simple home-user things with it.

    Hi!

    Just want to add up to the numbers here that I still have the problem with no WOL on my Macmini (late 2011), iMac (2011) and MBPr. I filed a defect report to Apple two weeks ago and have to this moment not received any response. I sincerely hope that there is some activity to solve this issue in Cupertino since this issue in no way could be considered as a minor flaw especially for those Macmini owners out there that uses this thing as a server.

    I have tried out the workarounds posted in this forum with no luck but I'm thankful for the efforts provided by the community.

    Wake for network access still not working with 10.8.1 on my Mid-2011 iMac 27" i7.   Irritating to say the least.

    Agree, 10.8.1 didn't fix any problems concerning wake on lan and/or stability of lan/wlan connection between macs running Mountain Lion.

    I didn't get any response from Apple yet, related to my bug report. I'm not happy with the situation.

    Hi everybody,

     

    sorry for being all quiet for some time, but I was moving. As I had to change my internet provider (now using cable instead of ADSL), I have new equipment now. The setup is an AVM Fritz!Box 6360 Cable router with the Mac mini connected directly to one of the router's Ethernet ports using a Cat. 6 RJ45 cable. The mini gets a fixed IP address from the Fritz!Box, was updated to 10.8.1 in the meantime and has the energy saving settings unchanged (go to sleep after 15 minutes, wake up on network access). The settings of the Fritz!Box allow Wake-on-LAN and it's activated for the Ethernet port the mini is connected to.

     

    What can I say - it works like a charm. The mini goes to sleep when it is idle and it's no problem to wake it up from the local network or the internet. VNC (port 5900) and EyeTV (port 2170) work, haven't tested Plex yet. Seems like the AVM hardware does the trick in my specific case, while the underlying bug has not been solved by Apple.

     

    I will continue with some tests and revert ASAP.

    I found a fix.  It requires editing system prefs plist to disable dark wake.  Reverse these instructions to restore dark wake.  Use at your own risk, I am not an expert.

     

    This allows your ethernet connected mac to wake on lan using a magic packet (with "wake for network access" checked in Energy Saver preferences).

     

    Open /Library/Preferences/SystemConfiguration/com.apple.Boot.plist using a text editor

     

    Change this:

     

    <key>Kernel Flags</key>

    <string></string></dict>

    </plist>

     

     

    To this:

     

    <key>Kernel Flags</key>

    <string>darkwake=0</string></dict>

    </plist>

     

    Save the file, reboot, and you are in business.

    Hey Kevin,

     

    The waking has been working for me too.  Have you noticed any thing different with regards to how your Mac goes to sleep now?  Mine doesn't seem to sleep on it's own - I have to ask it to.
