Q: Mountain Lion no Wifi after wake from sleep

I am reinstalling ML now, just to see. But, after a bit kore researching, has anyone tried to change the ipv6 setting to local only? Things imam seeing seen to suggest that there might be issues with this. As soon as I am back up I am going to run my usual wifi freeze tests, then change my ipv6 settings.

I'm game. Just set it now and will get back to you to see if it solves my issue. This has been annoying me since Lion and the only fix I've been able to come up with so far is to turn wi-fi off for 10 seconds and then turn it back on.

So it does not seem to help. I did the reinstall, then changed the ipv6 thing. Same progressive hard freeze when trying to reconnect wifi after sleep for about 3 mins.

Going to restore to lion. Disappointing.

Lets determine what is deep sleep? I've closed a lid for almost one hour and everything is working fine. Will close for all night long and then see what will happen.

For me, it's anything after an hour. My mac mini misbehaved at first when I installed Lion. Then it just worked after that. My MacBook Air was fine until I messed around with it and had to re-install Lion. Wi-Wi's been an issue since. I thought ML might correct it and it appeared to do so on the first day, but it's right back to misbehaving again.

My encryption is WPA-2. Come to think of it. I changed it from WEP around the same time I re-formatted. I haven't turned my mini on since I did all this, and I don't have the same problems when I'm at work (I don't know what kind of encryption they're using, if any at all). I'm beginning to wonder. I won't be opening my Air on for a few minutes. I'll see how the IPv6 change goes and go from there.

1 Hour would suggest that possibly Time Machine is involved? Maybe it's turning itself on to back up, going back to sleep.. But, when you wake it up manually, things go wonky.

Possible?

Would I have to be using Time Macine?

I've always used Apple Script and Automator along with rsync commands to do my backups. I'm a it old school. If Time Macine is somehow involved, how would I go about correcting this and why did it only happen after I did a clean re-install of Lion?

About the only changes I've made are with my router's encryption and I chose not to install MS Office this time around

No, Time Machine is not enabled. Now closing the lid, will see tomorrow what will happen, and then post here. Thanx!

I don't have Time Machine enabled either. I've been trying to look over the console logs just to see if there's anything I can't quite find anything that looks like anything. At least to my untrained eye. There seems to be a lot of little errors but nothing that just screams out Wi-Fi or something. Can somebody who knows more about reading console logs take a look? Still going to go back 10.7 at least for now.

Well, it's been over two hours of my Air being in sleep now and I just opened my laptop to see if the IPv6 fix worked. So far, so good. The real test will come on Tuesday when I re-connect at work and then come back home to try to re-connect.

This is weird. I decided to make another admin user, logged out of my main user account and tried to recreated the issues in the new account. The first re squire of the wifi took a bit and I thought it would hang like before. Then it came back. I even did the delete keychain items to boot. Tried a few more times with lid closed, etc. worked fine. Logged out of new user. Logged back into old admin user, my normal account. Everything seems fine. I hope. Will do a longer sleep test now and see. What would doing keychain management in another admin user do to this situation? I dunno.

I have these exact symptoms.

I'm not really convinced that it's network related, even though the Airport thing does seem to be searching for a network.  When its hung, I can't do anything in Safari, but from the terminal I can tell that I am actually connected to the network (ifconfig), and I can ping my router, perform DNS lookup, etc.even though the Airport icon is not completed.   

I tried killing SystemUIServer, since that controls those menubar items, but this didn't really help.  SystemUIServer didn't restart itself. 

Still investigating. 

Nope. Bonked on second wake up. Restoring to lion clone now. I did the terminal snoop like above poster too and see that I am pulling an ip address, but the menu bar and safari, Firefox and mail all go kablooee.

I'm having the exact same issue. Waking the machine from sleep and it hangs trying to connect to the network. Seems to kill everything. Last time it happened I had to hard restart the machine. (hate doing that).

Are we certain that its the network connection process that is causing the issue or is it just happening within those first few seconds of wake when the machine is still looking for the wifi network.

I had a weird thing happen right after I installed mountain lion where Panic's Transmit would hang when I started it up. Transmit has been open each time this happened but I doubt its related. However figured its worth mentioning.

Hope we figure this out soon.

BTW, I'm on a 15" MBP (mid 2010 model)

How do we officially notify apple of this issue? Any one know?

I filed a radr on it (a bug report); also, I've been harassing applecare.

BUT, I'm wondering if there's a common LaunchDaemon or LaunchAgent?

Here's my LaunchAgents and LaunchDaemons...  (click the image to see it all!)

To see yours, go to Macintosh HD -> Libraries -> LaunchDaemons / LaunchAgents

Is there a common program that's causing the issue?
