    I can confirm that since the 7.6.1 to my AirPort Extreme, my when my Mac mini server 'sleeps' it will 'drop' from my Shared Devices on my MBA, and I cannot "wake" the mini from the MBA  (at times, but not always)

    I was also on 11D50, and just updated to 11D50b, so maybe it will help my problem, but as it's intermittent for me, I won't know immediately

    ===I am not sure what it is. I do not think it is a"bug" in Lion.

    What you can do is taking out the power cable out of the TC, wait for 15 secs, put the power cable in again (I know it restarted after the FW update).

    ===Another thing: turn your Bluetooth off and try again.

    ===There is a (very small) possibility that the wake-up takes too long to succeed: set the hibernatemode to zero (this means that no "sleepimage" file is written nor read, this file has the size of your ram):

    in Terminal copy/paste this command:

    sudo pmset -a hibernatemode 0

    you can then put the following command to free the space of the sleepimage file:

    sudo rm /var/vm/sleepimage

    type Exit

    and quit the Terminal

    (ofcourse <enter> after each command)

    you can test the hibernatemode in Terminal:

    sudo pmset -g | grep hibernatemode

    and it will return the hibernatemode (now 0)


    The other thing is drag Energy Saver computersleep slider to "never".

    Sofar I could not find the perfect solution.

    Worked for a day, now my mini is in a coma again, needing me to touch the power button to wake up (so

    11D50b didn't work for me)

    Jonathan, good point about Terminal, but it is a powerful "tool". To inform you in general about the hibernatemode read this interesting article:

    Ok I'm having the exact same problem, I'm also trying to wake my MacPro using either the apple remote on my iphone or the a VPN app on my iphone to enable access to my content on an AppleTV with home share. All of which worked with no problems in Lion before the update to 10.7.3 and the airport extreme update to 7.6.1.


    Things I've tried:


    Reset the SMC on my MacPro, restart and test.


    Restarted my Airbase Extreme, both via the airport utility (6 and 5.6) and by removing the power cable for 30 seconds.


    Reverted to firmware 7.6 on the airport extreme. Restart and test


    Turning of and on Wifi.


    Moved my preferred network to the top of the list in the network preferences, restart and test.


    Add new Network Location and renew the DHCP lease. Restart and test.


    Turned off "Wake on Network activity", restart, then turned on "Wake on Network activity" restart and test.


    The only thing I haven't tried yet is to use the Combo 10.7.3 update to give me 11D50b, but since Johnathan216 has done the same and still no joy, along with all the other test I have done. I agree that it must be a 10.7.3 problem with the Airport Extreme keeping a connection with the MacPro.


    I'm also reluctant to do sudo commands as a fix.


    The only reason I changed my network router to Airport Extreme was for this function.


    If anyone has any further ideas on what's wrong or has anything else I can try, then I'm all ears.

    I have a wired connection from my mini to the Airport.  I've now also turned on the WiFi to see if that resolves my problem.

    WiFi won't wake it up, Tony. I've tried myself. I have a Linksys router and as long as I keep my Mini plugged in with ethernet, it shows up in Shared and I'm able to wake it without using the Mini's keyboard.

    That was my set-up (Mini plugged in with ethernet), but since 7.6.1, when the mini goes to sleep, it will frequently (but not always) drop from Shared.  The strange thing is, I have other devices (Squeezebox Radio) that will always wake the mini, but not my MBA.

    Ok guy's, may be early days but I have discovered what I think may be the solution.


    In system settings, network. On the left hand side there is all your connections (wifi, ethernet, firewire and so on)


    Select every connection that you are not using, one at a time. Go to the options cog a the bottom and select "Make Service Inactive" so that the only connection left is the one you use to wake your mac up.


    Save and close.


    After that, everything should work as desired.


    I have only tested this a couple of times this evening, once putting my mac to sleep for 30mins, then again for a further hour. Each time the Mac woke using the Apple remote to enable me to home share. This is still early days but seeing as my mac wouldn't wake after about 10mins every time last night I'm hopeful this is going to work.


    I'll keep testing it for longer periods of time but so far it has worked for me.


    Let me know if this helps you too.
