Mountain Lion no Wifi after wake from sleep

Hmmm interesting. I had it happen again today to but I was able to get out of it by killing systemUIserver in activity window. I leave activity window running at all times just for times like this.

I will look through console to see what is going on.

GUYS N GIRLS,

I updated to 10.8.2

All troubles are over

I put back the Trnasmit and wifi icons in the menu bar and all is workng as it should.

Hurray!

Well not for me. After update to 10.8.2 problems are worse than ever.

Sorry to hear this. Discouraging news.

I'm with you, seems worse.

Pleased to report that after upgrading to 10.8.2 I can now leave Transmit open while shutting the lid for the night and it connects just fine when I wake it. Haven't turned on Transmit Menu yet, but wasn't using it before.

Sorry to hear some are still having issues, but the original issue reported in this thread seems to be solved for us Transmit users.

Good luck to all!

Regarding "cheap routers," I have an Apple Airport Extreme base station circa 2007 and the no-network-upon-wakeup problem occurs for me.

Regarding 10.8.2, it sounds like some of the people saying the problem is the same or worse might be referring to different problems (e.g., Safari running slowly or crashing). I haven't installed it yet myself since removing the wi-fi menubar item has been a good workaround.

i'm experiencing the same problem.

I'm using an early 2011 13" MBP, and wifi was working reconencting fine when my laptop shipped with Lion.

After the Mountain Lion upgrade, 10.8 and 10.8.1 were working fine as well.

but when i updated to 10.8.2, i started experiencing this problem. wifi simply does not auto-reconnect after waking from sleep. i've tried the solutions posted in various discussions including:

---system pref > network > deleting networks, deleting wifi profile, deleting location profile, and recreating all of them

---removing 3rd party menu bar items

---deleting entries in Keychain access and reinstating them

nothing works.

Apple OS engineers kindly resolve this bug quickly!

turning off energy savers/turning off sleep/removing wifi status icons is simply not the way a laptop was meant to function.

What strikes me is that there doesn't seem to be any consistency in these reports, e.g., some report the problem has gotten worse since upgrading to 10.8.2, while other claim they're no longer experiencing problems. And some have seen improvements after removing the wifi menu bar icon (as well as all 3rd party menu bar icons), while others have not? Everyone, however, seems to agree that this problem only surfaced after installing Mountain Lion.

In my own case, removing the wifi menu bar icon and increasing sleep to 3 hrs has made a big difference in how often I lose my connection, but I am also rebooting my AEBS more often, too, so things are still not right.

For those with a little tech saavy, I'd suggest sending a bug report to Apple. I intend to do the same when I get the time.

I am now begining to think this is a problem with the interaction between 10.8 and some wi-fi routers. My computer never experiences the issue while I am at home only at work. At work we have 2 networks and it seems like I have the issue on only one of the networks. I am going to compare the routers to see what the difference is.

The quick fix if you get the systemuiserver hang (taskbar not responding) is to kill the porcess using the activity window. The process will respawn and everything will work again.

I noticed yesterday that my computer was generating a repeating error right before I had the hang...

Sep 21 14:03:08 Andrews-Laptop.local StatusMenu[669]: receiveSleepNote: NSWorkspaceWillSleepNotification

Sep 21 14:03:08 Andrews-Laptop.local StatusMenu[669]: receiveSleepNote: NSWorkspaceDidWakeNotification

Sep 21 14:03:08 Andrews-Laptop kernel[0]: PM notification cancel (pid 110, WDDMService)

Sep 21 14:03:08 Andrews-Laptop kernel[0]: IOPMrootDomain: idle revert

I have to do more research but I believe that the StatusMenu is the task bar. Interesting.

Antbody else have the same message in your console?

Apparentely, those forums are not getting much credibility from the Apple engineers: the 2d line on the AppleCare is etlling that this place is not taken seriously as it is perceived as a place where people only go to complain ...as I am somehow doing now. 🙂

More seriously, to wrap up:

- 1453 MTU size improved seriously the reliability

- disabling the sleep limited the "systematic" freeze that was happening when moving in sleep mode

- turning off WEP128 and moving to WPA2 Personallal ...forced me to throw away two fine devices that are WEP-only ...but only barely improved the performance ...not the (un)stability

- deleting all reminiscent entries from the "trousseau d'accès" (yep, I am French speaking: the translation must be key store I suppose) helped "somehow"

BUT in general I am still with a badnwidth that is on average 6 times slower than with Lion, and is extremely unstable.

The only reliable way to reestablish the network connect is to systematially go to the "network settings / diagnostic", to type an admin password to confirm network change although I am just confirming the current settings!! and then up you go everything move to green ...but it is so slow and last so short! ;(

I am not willing to go for another router, for sure. I have put on hold my plan to go for an iphone5 and I am considering again to buy ...a PC!

No Wifi problem anymore since updating with ML 8.0.2 Hurrah !!

The Wifi does wake up after inactivity. Waking up the computer and few seconds later (4 secs approx.) the wifi is connected and everything works properly.

Few days ago, I've had to make wifi inactive prior to leaving. Awakening the computer, I've had to make it active again. Manually, it works but kind of a pain.... Seems that it is all gone now !!

Here is my conf.

What else could be relevant ?

Another test. Now its midnight. Go to sleep. We'll see tomorrow morning if it is still relevant and gone as a problem.

Good night 🙂

Good morning !

I'm comfirming that it worked out for me with these setting above as mentioned.

Works properley and as expected.

Best of luck to whom it didn't work.

Regarding the issue with the whole system hanging w/ spinning cursor when waking from sleep:

This issue is fixed in Mac OS X 10.8.2.

if you're reading this thread and having that issue, please update to Mac OS X 10.8.2. 🙂

Best,

Cabel

Well that's obviously not the case. I'm running 10.8.2 and I STILL have this issue!
