Since it appears Apple is aware of this issue, for all you posters if you have a WiFi issue you should call AppleCare and ask them if you can get the fix that some guys have been mentioning here. Maybe that will help you out...

That problem fixed ehh? Wonderful...
Now once they fix the OTHER PROBLEM in the Mac Air which is software, that being the TCP window size would not scale beyond 64KB meaning on 802ac
TCP window size defines the amount of data that a server can send before the client has to acknowledge that the data has been received
Meaning on 802ac (5Ghz) the Air is maxing out 17 gig per second in Mac OS, this problem is limited to OS's Wi-Fi networking stack……so people are getting average 60% or so faster over 2012 Mac Airs.
Whereas when bootcamped, the same air is getting 47 gig per second.. or 158% Faster
There is a conflict in the Max OS with the next generation 802ac
When the OS is fixed to get FULL potency out of the new 802ac, its reported that they will be around “158% faster than the 2012 Air”
So, right now nobody anywhere is getting past 70% faster 802ac over 2012 models in Mac OS,…..but once this little OS issue is resolved, Air users will be getting 158% faster 802ac like the bootcamped 2013 Air that has diff. TCP than that of the Mac OS
That’s a lot to look forward too, likely 10.8.5 OS update, Im assuming.

I have bought new MBA (i7, 512 hdd, 8 gb) in Apple Store in Florence (Italy) and wifi connettivity wasn't good.
Yesterday, I have changed MBA in Apple store with a new one, but the issue is the same. Probably, these new MBA have a common issue.

Well, I’m still wondering while mine works. Maybe the Apple stores got an older batch than the one I got by ordering directly through the online store?
What does a WiFi ‘system report’ give out? I have this:
CoreWLAN: 3.4 (340.18)
CoreWLANKit: 2.0.2 (202.11)
Menu Extra: 8.1 (810.11)
configd plug-in: 8.5 (850.252)
System Information: 8.3 (830.5)
IO80211 Family: 5.3 (530.5)
Diagnostics: 2.1 (210.25)
AirPort Utility: 6.3 (630.34)
Buona giornata toscanaMacBook Air, OS X Mountain Lion (10.8.4)

I installed the update as well and it didn't solve my problem at all. There's no change.
well... so far so good for me.
mine is behaving well either on Apple APs and on a Linksys WAG120N configured for the "worse"... i.e. wifi is in Mixed mode,, WPA2 Personal, TKIP/AES, on channel 11.
To say the final word, I'll have to wait for Monday, when I'll be back in the office, where dropouts were constant and security is WPA2 Enterprise.
Since enabling my modem/router wifi (the WAG120N) that I've never used before having Apple Airport Extremes all over my house and connecting my MBA I have NO dropouts.
I'll get back to you on Monday...
BTW, I've looked into the package I've downloaded from appleseed and apparently there's a kext inside... no firmware or else, so the problem - so far - could be traced to the OS.
