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.

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.

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!
