I'm running Lion OS on an iMAC. Experienced the wifi - connectivity problems in regard to the Sleep function. In addition to this, I was also experiencing multiple drops in connection throughout the day- sometimes 40+ drops a day. iMac was also running extremely slow.  Reconnecting was not always easy, I would get multiple "time outs" and other times my network couldn't be found at all.


Since updating yesterday as per a gracious poster who posted this update


my iMAC is running faster. I have only had the wifi connect upon sleep problem twice, but it resolved itself quickly when I found my network and just clicked on it in the drop down. I have not had any drops since. I'm wondering how others are faring with the new update?

It might be a good idea for everyone to post which wireless router they are using....


I have an Airport Extreme 4th generation and am not having any problems...


Airport Extreme = 4th generation

Airport Utility = 5.6 (and 6.0)

Airport Firmware = 7.6.1


Some of you may be using an old router that the cat dragged in from the back yard.

Unless you tell us, we have no way of knowing what you have.....

I have friends that have older versions and aren't having these problems.


I think this is like buying anything else, they always want to sell you a new car.....


You could always buy a new one and keep your old one for Airplay to a stereo somewhere in your house...

Use the new one as the main base station and the older one to Join the network so you can play music... or printing to a printer in another room, etc....


Myself, I started out with on older Express, then added another to a stereo, and then another...

Sold all 3 older units on eBay for about half price and then bought 3 newer "n" version along with an new Airport Extreme...

The Airport Extreme is my main base station now and the others are hooked to stereos in other rooms and outbuildings....


Depends on how much you want to spend I guess....

    Worked flawlessly for me since I applied the update on Friday 2/24!


    Glad the problem has been resolved!

  • rockeeeeeee Level 1 Level 1

    I'm glad it's working for you-and flawlessly at that.


    I'm still encountering disconnect problems, but not severe. This morning upon waking my iMAC up, I had the greyed out wi-fi bars. I had to "check off" my network 3 times in the drop down of networks and then got connected.  (Before the update, I would get Time Out messages, and would have to unplug my router, re-plug it in and reboot to get things going.)

    For me, so far, while my iMAC speed has increased, and it is easier to get a connection, I still have to do a little work to help things along. But this is better than what was happening previously on my machine.

    I have updated the wifi yesterday on my Imac of January 2012 but I have had the wifi connect upon sleep problem twice and more.

    The problem isn't resolved ....

    I'm getting very desperate.

  • rockeeeeeee Level 1 Level 1

    Go to your Airport Utility and see if there is an update for it. A friend of mine did the wifi update and was still having probs, but I told her to check the Airport Utility for an update. There was one so she updated and so far, so good.

    Has anyone been able use this update with an older iMac?  Mine is a mid-2007 that has the wake from sleep issue.  I've been hesitant to try 10.7.3 since others have had a problem with it.

  • rockeeeeeee Level 1 Level 1

    You shouldn't have a problem with the older iMAC. My friend has the older version, (mid '07) and did the update and said it's working great with no issue so far.

    My question to you is, why do the 10.7.3 update? The newest update is v1.0. It makes a definite improvement.

    I had perviously updated to the 10.7.3 and my issues are stated above in my first post - it wasn't limited to the sleep issue, I was also having multiple drop outs through out the day. Not only that, but it wasn't easy to get "connected" again.  I would suggest giving the newer update, v1.0 a shot. Make sure your router firmware is up to date, first. Another thing you may want to try is: After you check that your router firmware is up to date, then do the v1.0 update.   Check and see how your connection is, then let it sleep a bit and check again. If you still have the problem, unplug your router for 30 seconds and then replug it back in. Keep us posted.

    Thanks for the super fast response.  I'm going to be gone for the rest of the day so I'll give it a try tomorrow.  I'll keep you posted on the result.  By the way,  my problem started after the upgrade to Lion last year.  I solved it by replacing my router and then my modem.  But lately the wake from sleep has come back along with the occasional drop.  I would love to get this settled once and for all.

  • rockeeeeeee Level 1 Level 1

    Yes, it appears that the problem started for a lot of us after upgrading to Lion OS. (My other Macs that do not run Lion are not affected )  Good to hear that you did replace your router and modem and had some resolution. I take it you're still using the 10.7.2? Definitely update when you can to the v1.0 and let us know! 

  • lenny491 Level 1 Level 1

    This update most definitely worked for me!

  • rockeeeeeee Level 1 Level 1

    Glad to hear that it's working for you! What year is your iMAC?  Thanks for letting us know


    I just lost my connection again, but with this update, I am able to reconnect faster. I have a late 2009 iMac (November).  My router is from 2006. I think I'm going to have to replace it with a newer one.

  • lucas_l Level 1 Level 1


    This Wi-Fi update 1.0 indeed fixed reconnecting after sleep, but I'm still having dropouts (wifi bars grayed out, imac tries to reconnect without luck). My iMac is mid-2010

  • rockeeeeeee Level 1 Level 1

    Try this: unplug your router for about 30 seconds, then plug in again. Then, reboot. It works for some, but not all. It might work for you. Good luck!

    There is no way she could have preformed the iMac update on her 2007 model.

    This update was only for 2009 iMac models and newer....


  • Peter_Belgium Level 1 Level 1

    After a struggle of 8 months ( I bought a brand new 2011 Imac last summer and unfortunately upgraded after 3 weeks to Lion), the just released patch does not solve the issue...


    Still the same problem: after getting the machine awake the wifi-icon shows an exclamation mark; sole solution: put wifi off and reconnect... This is causing much frustration. I'm about to put the whole **** on ebay and get back to a working Windows-machine. My disappointment is hugh !!!!!
