Resolved 10.7.3 no WiFi after waking from sleep (iMac)

no dice for me, I've tried all the suggestions so far, nothing cures it!
Grrrrrrrrrrrr!!!!!
I guess I should have knocked on wood because I seemed to develop an intermitten Wi-Fi not reconnecting after sleep. What I did to finally resolve this was create a new network location. When it seemed like the network reconnect was stable I then deleted the new network location. Now the network seems to reconnect after wake from sleep very consistently. The way I tested this was to manually put the Mac to sleep then wake it up and observe if the network reconnected. Hope this helps.
My supposed fix drew a blank in the end. I think i'm reaching my tolerance limit ifi get this issue again (just emptied System Config folder again) i'm packing up and reverting to Snow Leopard.
I could run my mac for over 30 days without so much as a flinch yet with Lion i find myself restarting every other day to clear out one issue or another. Ridonkulous.

I urge this simple trick to see if it fixes the sleep problem.
1. Open System Preferences->Network pane.
2. At they top of the pane is the "Location" drop-down, use that to select to make a new custom named Location (in Lion you will have to select 'Edit Locations', then in that drop down clicking on the + button to add a custom name Location).
3. After you made then new Location (naming it whatever you want) lick on the 'Apply' button, in the Network panel, to save this new location.
Don't worry because it will act the exact same as the 'Automatic' Location.
Also try the trick to Reset the Finer's contextual system:
In /Applications/Utilities/Terminal and put in the command:
1. Open System Preferences->Network pane.

this was happening for me with a new macbook pro, in 10.7.2 constantly.
what fixed it for me was, switching from a 5ghz only wireless network to a 2.4ghz wirelessN network.
my speeds were NOT visibly different, but i've had (almost) no real problems reconnecting after waking since.

This is happening on my mid-2010 iMac i3; didn't happen in 10.7.0, 10.7.1, or 10.7.2. Tried to fix it by installing the combo update over the delta update (twice, actually), repairing permissions, and deleting/reconnecting to the network. No dice. At this point, considering how minor of a bug it is (and can be worked around just by pressing the power button to wake instead of the mouse/trackpad), I'd just wait for a fix.
Here is my fix....new router
I have a mid 2011 i5 3.1Ghz iMac. Ever since the Lion install no reliable wifi connection. Just hooked up a Netgear N300 and the darn thing logged right on and hasn't missed a beat since.
Admittedly this is only a few hours, but it already has surpassed any connection in Lion previously.
Could that be it? I will let you know my experience. I have been reluctant to advise folks to upgrade to Lion because of this wifi issue...but now this might be at least a path to a remedy....my other routers were all several years old and also Netgears. What might have changed ?

So I have stayed connected without a hitch. Wake from sleep (4 hours) no problem. Just thought you would like to know.

This may have already been mentioned, but perhaps not:

Just happened to me on 10.7.3 on a mid-2011 13" MBP running Lion. The MBP has been fine since May 2011, original was SL, upgraded to Lion, never an issue with wi-fi until I used the combo update over the weekend. Can't imagine what it is in 10.7.3, but I had to reboot to get wi-fi back. I sometimes use wired ethernet, don't know if that is an issue or not. When it isn't working it thinks it's on wi-fi but the symbol shows an error. Very annoying considering it's worked fine until 10.7.3.
** Additional info ** Doesn't happen every time. Wi-fi is a FIOS router, no changes to the router. I'm trying via logout before closing lid to see if there is any difference.

At this point, I'm waiting for a fix, as I'm sure this is a bug, and furthermore I suspect Apple knows this too.
Just to be clear, this issue is when your Mac doesn't automatically select a known network after waking from sleep from a keyboard press.
* It's not that the network was forgotten (it's not)
* It's not that wifi is dropping in and out
* It's not a 10.7.x issue (it's specifically 10.7.3)
Pressing the power button on the Mac is the workaround. Or, just select the correct network if you used the keyboard.
Irritating, to be sure, and I'm a little bemused to hear of 10.8 going out, which may mean less resources applied to fixing things like this. I understand Apple to really run lean for SW development, so I'm a bit concerned here.

I just got a MBA a couple of weeks ago. I installed 10.7.3 out of the gate and then setup my preferences and apps. I setup a network preferences location for my work wifi which uses a proxy and Enterprise WAP and when I got home, I setup another location for my home Wifi. When I got back to work, I had nothing but problems connecting to Wifi (and of course I was selecting the work location). It would not reconnect out of sleep. Sometimes it would not see any SSIDs (even though there are several in range) or it would not connect to it's known network and even after selecting it again, it may not connect promptly. It was a nightmare. Not much unlike what I'm hearing in this thread.
I then removed all remembered networks, all locations, all proxy settings, and rebooted. I connected to my work wifi from scratch, setup my proxy settings again, and saved that as a location in network preferences. From then on, it's worked fine. Connects immediately upon resume from sleep. I haven't bothered to setup a new location at home. I just use the same one.
Who knows what's at the root of this. Of course, YMMV but it's worth screwing around with locations and/or starting from scratch to see if you can clear up your issues.

Update...Even happens after rebooting! I had to reboot twice to get back. I've NEVER had a wi-fi issue with any of my systems before! I have a Superduper clone of 10.7.2 and may go back to it. it is extremely annoying!
**Another update **.... Interesting...All of a sudden can't connect to wi-fi at all! even reboot. Even tried switching to wired..nothing. Rebooted router. Now connecting. I wonder if 10.7.3 is doing something that confuses the wi-fi routers and causes them to run out of IP addresses? Or maybe it's specific to a kind of router? ie..some have no problem..others do?
Apple forum shows lots of people having trouble with 10.7.3 wireless.

Also some people in here should read the Apple document Troubleshooting Wi-Fi issues in OS X Lion and Mac OS X v10.6.
This is a useless link. It is not a range issue, dropping or security issue. It is also not a simple hardware reset issue. This is a bug in Lion for certain machines that do not reconnect to the network after sleeping and or have very slow initial connection. It appeared in Lion and IMHO is clearly a bug.

** Update ** since resetting the FIOS router (power off/on) I have had no problems with wi-fi reconnecting after sleep. It's been to sleep at least 6 times today.
Lion, back to Snow Leopard
I was having the same problem of wifi not connecting when coming out of sleep on Lion. I have reinstalled Snow Leopard and it connects every time I wake my Mac so I would say, like many others before me, it's Lion.
