Q: Wifi unstable

My MacBook Air (MID 2012) keeps dropping the wifi connection after upgrading to OS X Mountion Lion.

 

Every couple of minutes the internet doesn't work but the wifi symbol says that it is still connected. After deactivating and reactivating the wifi it workes fine until the next wifi drop.

 

What I have alreday done:

- Reinstalled Mountion Lion (2x)

  - Added other DNS Server

  - Changed the MTU

  - "KeepAlive" bash (ping router)

 

What should I do?

MacBook Air (13-INCH, MID 2011), OS X Mountain Lion

    Spoke with Apple Care who fixed my intermittent network connection issues after having upgraded to Mountain Lion:

    This is what he asked me to do:

    1. Go to your Macintosh HD drive in Finder (system drive)

    2. Go to Library

    3. Drag the 'SystemConfiguration' Folder onto the Desktop (creates a BU copy - just in case)

    4. Delete the 'System Configuration' Folder within the 'Library Folder' (empty the Trash Bin - just in case)

    5. Reboot - This recreates the network files (automatically)

    6. That's it!

    Works now like a charm

    P.S.: Just in case if you have done custom network configurations, write them down first.

    PPS: I did the above and it works, but please don't hold me liable for anything you do on your own machine : )

    I am having the same problem with a MBA 2,1 (mid 2009) after upgrade to 10.7.5... but not with my MBA 4,2 (late 2011).  I am using an Apple time machine/router that is almost new, so it is not the network. It seems like this is an Apple OS problem as it is intermittent and only started with 10.7.5 upgrade.

     

    seems like the best advice is to downgrade to 10.7.4.  This is why Apple really misses their chief product manager, Steve Jobs... they keep putting out product that is not ready for prime time.

    This method worked for me fine, but since I have upgraded to 10.8.2 I have the same problem as before. :/

     

    PS: I have a MacBook Air MID 2011 and not MID 2012
