Macbook Air 2011 11" - random freezes. Roaming wifi causing it?

I have MacBook Air 11" Mid-2011 (4GB RAM, 128GB SSD, i5). Ever since getting the machine I've experienced random freezes - spinning beachball, screen becomes unresponsive, holding the power button to force it to close being the only thing I can do. The console logs don't show anything that indicates a problem. They just stop logging anything until I restart. I took it to an Apple store Genius while still under warranty and they kept it in for a few days and ran a suite of tests and found nothing.
The problem was completely random and unreproducable. Sometimes it would happen a few times in a row, then nothing for weeks. Also, it was only happening when I was staying in a particular hotel during the week for work. It was Hilton hotel with the wifi being provided by BT Openzone. It would only happen there, never at home, family members house, Starbucks (which also use BT Openzone here in the UK, airports).
I recently made some changes to my home wifi setup and the problem has reappeared, but this time at home. Where previously I just had an Airport Extreme, I have now extended the network over ethernet powerline to a second wifi access point. The second wifi access point has the same SSID as the main network.
All my wireless devices should seamlessly switch between access points as I move them around the house. Our iPhones, iPads and Dell laptop seem to have no problem doing this. When I move away from one access point, once the signal strength drops to certain point, the device connects to the second access point. The MacBook Air also does this, but it seems to freeze if I am in an area where the signals are overlapping. This also describes the situation in the hotel. The BT Openzone hotspots were spread across the hotel. If my room was in an area where the signals from access points were overlapping I would be more likely to experience the freeze.
If I look in the Wifi logs I can see messages stating that some sort of threshold has been reached and the wifi is starting roaming. These messages are always present at the time of the freezes.
Has anyone else experienced this problem? Is it something Apple would fix eventhough I'm now out of warranty? If it could be a hardware problem, would replacing the wifi card myself help?
cheers.

Macbook Air 2012: intermittent, random freezes of trackpad and keyboard lasting a few seconds each

There have been a few other people to have reported this problem, but there has been no consistent solution for me on my Macbook Air 13" 2012, running 10.8.4.
What happens is this: while typing, the built-in keyboard and trackpad will suddenly lock up at the same time, randomly, intermittently, and for just a few seconds before returning to normal. This has been true through all the updates of 10.8.x since I bought the system last year.
During the freeze, one of the three behaviors occurs:
1) both keyboard and trackpad are completely unresponsive
2) both keyboard and trackpad get really slow, with high latency. Keys pressed show up much later or have to be pressed several times before registering. Trackpad is jumpy if it moves at all.
3) key gets stuck, sometimes the BACKSPACE key, which usually results in several dozen emails getting deleted or entire paragraphs, or rows and rows of the same stuck key. Pressing other keys does nothing.
I've spoken online with various other people who have the same problem and confirmed that the built-in keyboard and trackpad seem to be joined together whenever this problem strikes. You never see one freeze without the other also freezing.
Also, these commonly-recommended solutions don't work:
a) Reset PRAM. Done this many times. Does nothing.
b) Bring it in to Apple. Did this too. They replaced the keyboard and trackpad but the problem remains.
c) Clearing caches in safe mode. No improvement.
d) Removing "com.google.keystone.deamon.plist" and "com.google.keystone.agent.plist" doesn't seem to work either, even though the errors and behavior are exactly the same for me as for george.e.gonzalez in this thread: https://discussions.apple.com/message/19702976#19702976
These files do come back, though, thanks to Google Software Update. The keystone software appears to be part of Google Chrome, although I cannot confirm this.
e) I DO have Google Android File Transfer installed like one other person reported; they said uninstalling it fixed the problem. Unfortunately, that has not worked for me. Also, Android File Transfer is installed (same version 1.0.50.2266, same Mac OS 10.8.4) on an older 2008 Macbook, and it works fine, which points to something on just this Macbook Air as being the cause.
f) I don't use the Radio Silence firewall app--can't remove it.
g) I don't have the telldus device or whatever it is, so I don't have the "com.telldus.service.plist" to remove.
h) Completely clearing out /Library/LaunchAgents, /Library/LaunchDaemons, and /Library/StartupItems doesn't do anything.
i) Repairing permissions or repairing the volume does nothing.
j) Reinstalling the OS fresh does nothing.
k) I don't have an external trackpad, mouse, or keyboard for testing while the freezing happens, but the machine itself seems to be working, just not the built-in input devices, which are on the same USB bus.
l) Pressing ESC does not stop the key stuck situation, as it does for some people.
It feels to me like a hardware problem, not an OS problem, and it feels like a USB bus issue. I have noticed that when I insert USB flash drives, I get the same lock-up for a few seconds, something which my other Macs don't do.
I've also noticed various USB errors in the Console around the same time (same as george.e.gonzalez):
7/26/13 1:20:04.000 AM kernel[0]: AppleUSBMultitouchDriver::_deviceGetReport - DeviceRequest for reportID 0x0 returned with result 0xe000404f - retrying
7/26/13 1:20:05.000 AM kernel[0]: USBF: 844075.636 AppleUSBEHCI[0xffffff80157f1000]::Found a transaction which hasn't moved in 5 seconds on bus 0x1a, timing out! (Addr: 2, EP: 0)
But I'm not able to precisely correlate these errors to the pause.
Is anybody else having this problem that can shed more light on it than these other suggested repairs? This has been frustrating for quite a while, but I've had the stuck BACKSPACE key delete hundreds of emails on a webmail platform that I was unable to recover using Undo and out of the trash, and that's just no longer tolerable...
Thank you, thank you, thank you, if anyone can help me fix this!

Hi, Dan--
Nope, none of those four... I do have Dropbox but never installed it on this machine. The other three are services I've never signed up for.
I am basically using these apps up-front:
Mail.app, Safari, Notes, Terminal, maybe LibreOffice 4.0.x, maybe Sublime Text 2, Console.
And the freezes happen about twice a day, usually when I'm in Mail or Terminal, but that's because those are the ones where I'm typing the most and can see immediately when the freezes happen. It could be happening even more frequently while I'm browsing, but I might not know it because I'm merely reading what's on the screen.
This is a list from Activity Monitor of what I'm using right now, which is very typical of what I use all day:

If you use a trackpad and don't want to switch to a mouse, you can uninstall and reinstall all day long and will still have problems, but if you really want to try it, you can download PSE 12 here:

How do I connect my MacBook Air 2011 to a projector?

How do I connect my MacBook Air 2011 to a projector?

It depends on the input connection for the projector, but since many are rduced resolution, VGA seems to be the prevalent common connection.
It's just a matter of buying the adapter that adapts VGA to the Mini DisplayPort/Thunderbolt port on your Air. If it is a DVI or HDMI connection input on your projector, the online Apple Store carries that as well.
This adapter and sufficient length VGA cable is all you need for VGA.
Here's the DVI adapter.
For some reason, I am unable to bring up the Moshi HDMI adapter on Apple's site.

d Pacifist to reinstall both the Safari

was that before the 10.4.6 combo was applied?
Nope, I tried the Pacifist route after applying the combo update.
It does sound as if webkit is busted at the moment.
What version of osx is on your install disks?
Not sure, I'll have to check them.

Whatever you read was incorrect. You can upgrade directly to Mavericks. It is in the App Store and is free.
Snow Leopard predates the operating system you already have. That's the reason it will not install on your MacBook Air. You spent $20 needlessly for it, but it's yours to resell if you wish.

If you used Boot Camp to install Windows you may use Boot Camp to remove it and return your drive to as it was.

What version of OS X are you using? If Yosemite, you need to update to 10.10.1 or higher.
In any case, start by going to the editor preferences>general, clicking this button and restarting the editor:

Connecting Macbook Air 2011 to Epson projector for Keynote

Hi,
I'm trying to connect my Macbook Air 2011 to a brand new Epson (Powerlite 1760W) projector for Keynote presentations.
I bought the recommended Monoprice mini cable from the Apple store but I can only plug it into my MBA (small squarish socket), the other end dosen't connect to the projector. It seems the projector wants a VGA cable into it.
I'm lost. Do I still need the UBS cable between the two? Do I need a USB / VGA cable instead?
Thanks in advance.

Alison,
In looking at the technical specifications (on Epson's site) for this device it would appear that you can make HDMI work - http://www.epson.com/cgi-bin/Store/jsp/Product.do?sku=V11H361120&BV_UseBVCookie= yes
That being said, the HDMI end on the adapter and on the projector are most likely female. So you'll need an HDMI cable (the length will vary on how far the machine is away from the projector) but I suspect a 3 or 6 footer would work just fine. The cable is a male-to-male.

Is the Macbook Air 2011 able to run the Apple Cinema Display 30" ?

Hello Everyone.
So, I am about to buy a Macbook Air 2011 11".
I want this product because of the ssd driver and the versality of such a light object.
The things is that i work at school with a laptop, and when i come back home, i use my Apple Cinema Display on my Macbook Pro with the Dual Link dvi Adaptator (which cost me 98€ ouch !! ).
So i read that there were kind of retro-compatibility between Thunderbolt and Mini-Display Port on the new Mba.
Is the 2011 mba able to run my external display ?
Thank you.
Nicolas.

Yes.

Guy would this be of any help:
To start up your computer in Apple Hardware Test:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears. If Apple Hardware Test does not start up, see the Additional Information section at the end of this article.
Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
It takes a minute or so for Apple Hardware Test to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
The Apple Hardware Test console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
Your test results will appear in the window in the bottom-right of the console.
To exit AHT, click Restart or Shut Down at the bottom of the window.

MacBook Air 2011 Fan increased after installed mountain lion

Hi all,
I have a Macbook Air 2011, Intel core i7. After when I installed ML I noticed that battery go down very fast (about 2:40h) and the Fan speed RPM is about 6500 all time, but I haven't any strong operation pending or App. I have the same app open since lion (Internet, chat, jdownloader) in background (skydrive,evernote,weatherhd) the same app and background task I have with Lion.
In monitor activity all task is from 1% to 20-30% of usage.
Any Tips?

I only have the fan kick in when the graphics is getting hit hard (playing games, driving external displays, etc) with crappy intel on board graphics.
Is your MacBook Air in a protective case, skin or having anything block the vent hinge?
Definitely sounds like the OS thinks it needs to keep running the fan.
You might try this smart temperature desktop widget and monitor your temperature to see if there is any sane reason for the fans to be on (they are loud!).

MacBook Air (2011)

MacBook Air (2011) needs 20 plus seconds to restart (about 12 seconds when new). Anything wrong?

Could it be that you added one or the other app and driver since you bought it which get loaded during start-up? Check under Login Items in your user account, and think what other "utilities" you're running - eventually silently in the background.
20 seconds isn't too bad. Once it's minutes, come back here.

Firmware update on a Macbook Air 2011

Hello guys, i have a Macbook Air 2011 that had the hard drive damaged, i installed a new one so him only starts on the Utility Page for Reinstall the OSX...
This version of Mac Air are with troubles to Download/Reinstall the OSX using the Utility Page, him needs a Firmware Update to fix, but i just can't open that Update on the Utilities Page, i tried to put the Update Archive on a Pendrive using other Mac, and i just put the pen drive on the Mac Air and tried to execute the update file using the Terminal, but i got the error: cannot execute binary file.
So how i can fix that Mac?
I can't execute the Firmware update, and without fix the firmware update i can't install the Osx, i also tried to install a new version using the USB Drive Bootable Mountain Lion, but this kinda of Macs Air 2011 only accept a custom Lion OSX, that can be downloaded after the Firmware fix..
Hope someone can help!
Thanks

You replaced the the SSD in a MBA that cannot be user serviced, so that's quite an accomplishment. Your model does not require a firmware update to use Internet Recovery - Computers that can be upgraded to use OS X Internet Recovery. Here's the process you follow:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

Macbook air 2011 reinstall problem

I'm really tired

please help me

OS X Recovery requries a broadband connection as noted > OS X Recovery
There's no need to hold down the Option key to restore OS X.
Hold down the Command + R keys.
If your download speeds are less than 10Mbps, you may not be able to restore your Mac using OS X Recovery.
