10.7.3 - late 2011 iMac - update broke returning from sleep and connecting to wi-fi...

Was on the phone with Apple for almost 1 hour and after walking thru almost everything listed on all these post I was told they are working on a patch!! No time frame yet, When it will be out!! And to think Apple stock hit a all time high today!! 😕

I had the same experience last week. On the phone with Apple and tried all things already posted until the phone tech asked someone about it and was told there is no permanent fix yet. Apple is working on it but no time frame.

My post and fix by repairing permission is not the whole story, maybe not even relevant.

I've had the failure to connect a couple of times; but then I again select my network and my iMac connects on waking. I've ran verify permissions a couple of times and even though the permnissions are incorrect on

Permissions differ on “usr/lib/ruby”; should be lrwxr-xr-x ; they are drwxr-xr-x , I still connect.

So I just live with this until Apple fixes the problem whatever it is.

for what it's worth, my problem has sort of 'fixed itself'. After trying repair permission and reselecting the network a few times I simply left it and for the last few days (waking it up >30 times) it keeps connecting without problems

This update just came out on Feb 24, 2012 and seems to have resolved my issue:

Yes, it does look like that the issue has been solved! Finally!!!

Yes, it worked for me too. Thanks Apple Engineers!!!

Does seem to work for me, too. I have been through all the other "fixes" on the various threads and none of those took care of the problem with connecting via wifi automatically after waking from sleep. This patch from Apple does! I can wake with the bluetooth keyboard or the trackpad, or BT mouse and it connects in less than 1 sec. every time (like it is supposed to!). Frustration over!

Hey, try out the patch on page 7 of posts (from Apple, Feb 24). It worked for several of us.

Patch fixed it. I for one will be less likely in the future to download point updates.

The new patch didn´t fix my "no wifi after sleep" problem.

Waking using the power button works though.

How many preferred networks are there in your preferred network list? Go to System Preferences - Network - click on WiFi then advanced. If you have multiple, I would pair it down to just the one(s) you need since more iMac are not too mobile and give it another shot.

I only have one preferred network.

The Patch fixed my issue!! 🙂

Just purchased Airport Express. Working a treat. Reconnecting ti Wi Fi every time.
