Andrew, thanks for the hint ...
... but in my case I have the SSD in the primary hard disk bay and the HD in the optical drive bay. Everything worked well with 10.7.5 for monthes.
I still suspect a hardware issue with the SSD. In the meantime I have completed a full restore of my users data, applications etc. to the HD. When putting it to sleep everything is fine ... except for the SSD. It was mounted as /Volumes/SSD. But when I wake up the system it claims I should have unmounted the disk properly and the SSD is gone. It is not even shown as a disk in "diskutil list"! So if it is not a hardware issue ML seems to have problems with SSDs!?
i have the basic 15 inc retina macbook pro, no changed configurations. It was bought like a month ago. The issue is with wifi. When i close the laptop and it goes to sleep when it wakes up it doesnt connect to the automatically i have to click it. I did actually see the same issue with lion but that was with my 2008 white macbook, and then i decided to downgrade to snow leopard again and it was all fixed.
Hey guys - have a different twist on this issue...
Late 2010 MBA, just upgraded to 10.8.2. No secondary disks involved; FileVault and password on wake active.
After upgrading from Snow Leopard, I have significant WiFi connectivity issues - to the point that even though I have a "full signal" on the menu bar indicator, I have absolutely no connectivity. The occurrence is random, happening sometimes on waking w/ lid opening, and other times even when lid-open but walking to another area. It even happens sometimes while sitting still. When it happens, NONE of my internet applications will work - IP printing, Citrix, Outlook, DropBox, Safari... even if they were connected previously.
The only way I found that works around this is when I toggle the WiFi on/off (which sometimes takes several cycles). I've also tried deleting/replacing all my remembered networks, to no avail. (Using WPA2 Enterprise/PEAP security, BTW)
I'm presuming this is a WiFi-to-Access Point issue. Problem is, I'm in a big corporate healthcare environment, and it's not like I can ask the IT department to replace or change settings on thousands of access points around the facility. What kills me is that this used to be flawless under Snow Leopard.
I've posted on this thread previously. Had the same problem with connectivity after upgrading to ML. Got some relief initially, it seems, by taking the Wifi icon out of the menu bar and putting computer to "never sleep" but the fix was obviously not permanent. When I lost connectivity 10-12 times in one day, I thought, what the ****, I'll replace my older AEBS (2006), even though many on here have said it wasn't a hardware issue. The good news is that I no longer have any problems with connectivity after buying a new AEBS. Probably not very helpful for you given your circumstances at work, but it might be helpful for others.
I also have posted a while ago in this thread about the same problem.
Meanwhile I have found a workaround which works for me. This is what I did:
First I changed from Safari browser to Chrome browser ( because the issue always started after using the Safari browser, after waking up from sleep mode of course)
Then I switched off the WiFi on my iMac and removed the wifi icon in the menu bar. Internet connection is thru Ethernet.I realize that this is not an option for the MacBook users.
My WiFi network is still working good, I use it for my MBP ( still on Lion) and my iPad and iPhone (still on ios 5.1.1).I have no wifi issues with them. Unlike many hundreds of people who have wifi issues after upgrading their iPad and /or iPhone to ios 6. Read the threads on this subject elsewhere in this forum.
Remarkable that in all these cases the wifi problems starts after upgrading the Apple OS (Lion to ML and ios 5.11 to ios6). Is there a connection?
And then this: A few days ago I received an email from someone who said he was an Apple engineer.
I will show the text with out the name for privacy reasons
I work for Engineering in Apple and would like to help look into the wireless issues reported by you. Here are some things I would like to get so I can get a better idea of whats going on:
Enable debugs by pasting this in Terminal: ( Hit Enter after entering this command)
sudo /usr/libexec/airportd debug +alluserland +alldriver +allvendor
Reproduce the issue. Please note down the time the issue occurs and send it to me in the email.
Now launch WiFi Diagnostics ( Option click on WiFi Menu Extra) and select Create a Diagnostic Report and email me the Report it saves on the Desktop.
In addition, please provide your Wireless Router make and model.
Please do not hesitate to contact me if you need any help with the above. Please feel free to add any other information that you think could be helpful in debugging this issue.
Did anyone receive a similar email?
Is anyone familiar with the code which has to be pasted in Terminal?
I mailed back that having found a workable solution for me I could not do the things he requested, because I did not have the problem anymore (for now).
I checked the source of the email which looked authentic to me.
I do not know what to think of this. Could this be some kind of hoax, or is it a genuine effort to help us poor people?
Glad to hear you found a workaround for this issue. I suspect there is something in the OS software, though in my case, I'm stll running ML on my iMac and MBP, and iOS 6 on my iPad. So, I have to conclude that my connectivity issues had something to do with the way the software interacted with an older router or the older router's software.
I wouldn't doubt the authenticity of the email you got from an Apple engineer. I got the same email, but I also filed a bug report previous to this email from Apple and had provided them with additional diagnostics as requested. I think they're genuinely interested in getting to the bottom of this issue and fixing it.
sorry to hear your issues are not solved yet. Mine were probably from a different kind, although not solved.
Because after switching on wifi in my iMac it does not take long to get the spinning ball and freeze back again.
So my iMac is working well as long as I use only the ethernet internet connection. This is not a solution of course.
I am glad that the mail is authentic ( I had an idea it was, that was why I answered it).
If and when I have the problem back again I will provide all the info asked for. Hopefully this will help the engineers to solve the problem.
Good to know that in some obscure way Apple is watching this forum, be it via via.
Ah, I agree...this solution wouldn't help me at work. It's unlikely that I can get the entire corporate network setup to change for an essentially "BYOD" Macbook Air.
I hate to think that my long-term solution is to get a Windows ultrabook instead... especially since the battery life for the Air under Windows is much worse than OSX, and that there's no guarantee that a dual-booted Air would work anyway. In any case, I'd have in-house IT support rather than "DIY".
Edit: oh, and as for being contacted by Apple Support - I've had those e-mails, too - over issues with Time Machine (which may/may not be related).
Weird thing was getting a phone call from Texas, rather than California to go over the issues...
And for what it's worth, I even lost connectivity editing this stupid post while sitting still at a desk.

Oh, sorry about the acronym. I bought my AEBS back in the beginning of 2006, so it was over six years old. Back then, it was based only on the 802.11b/g protocol. It wasn't until 2007 that the 802.11n came out. The current AEBS 802.11n (5th generation) came out in June, 2011 and has simultaneous dual band radios, which means it can operate in both 2.4 GHz and 5 GHz ISM bands.
How long have you had your 2nd gen AEBS?
Since my connectivity issues completely cleared up after replacing my older AEBS with this new one, it seems that you might also benefit from replacing yours?
