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

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

I have upgrade from Lion to Sierra and hoped it help fixing the issue, but it doesn't.

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.

Also try turning off Bluetooth.

WIFI AND BLUETOOTH FINALLY SOLVED, NO REALLY - YOSEMITE 10.10

If your Wi-Fi source is capable of generating a 5 GHz Wi-Fi network, try that to help avoid conflicts with Bluetooth.
