Hello, There is problems related to WiFi with macbook air 2013 and windows 7 x64 via bootcamp.

Problem appears when firstly booting mountain lion then if i choose restart>keep alt option>choose windows> WiFi adapter dead.

If i shutdown MBA, choose firstly windows, no issues with WiFi.

Also at bootcamp support site http://support.apple.com/kb/DL1638 at system requirements macbook air 2013 isn't listed. So maybe new macbook air isn't fully supported by bootcamp drivers? any thoughts?


MacBook Air, OS X Mountain Lion (10.8.4)

    Had the same problem. From doing a few hours of research it appears as though the bootcamp support packages Apple has out are not up to date for the new wifi Broadcom cards. Make a long story shot, I did some Hardware ID vendor searches and found out that a recent ASUS windows machine carries the same Broadcom AC 5G chip. I grabbed the driver, installed it (device manager picked up the unknown device). I did a full power cycle (shut off the machine for a while), rebooted and bam, internetz.

     

    Here's what you need to search: ASUS PCE-AC66 802.11ac Network Adapter.

    Good luck and let me know if you're still experiencing problems.

    Can you tell me which EFI update you downloaded?

     

    Are you able to provide a link please?

     

    I just purchased a Macbook Air but the update found in the link below doesn't work.  It says it doesn't support my computer.

    Make sure Mac OS X has been updated to 10.8.5. Then make sure you have the Macbook Air SMC Update v1.9. Both should let you run the EFI update.

    Non of the suggestions above worked on my MBA 2013 Bootcamp 5 with windows 7 64 bit, Wifi was still unstable and could maximum be connected for 1 minute. Irritating.  This is what worked for me, no problems since:

     

    1. Connect to your wifi network.

    2. Right click you network name in the taskbar and go to Properties.

    3. In the Window that appears, go to the Security tab and click the Advanced Settings button.

    4. In 802.11 settings, enable Federal Information Processing Standards (FIPS) compliance for this network.

     

    Voila!

    I had the same problem...spent hours on different solutions.  Turns out that the fix for me was simple but obvious.  I logged into my wifi router and changed the channel from Auto to a specific channel.  I chose channel 7.  As soon as I did that, all intermittent behavior and dropped wireless stopped immediately.  Very stable connection now.  Hope that helps!

    @lebage - that is an older driver than the one that boot camp installs.
