Thanks but i am testing a laptop (Dell 2011 i3 using Windows 7) which is nearly 2.5 years old and half the spec of my "advanced" laptop and gives 2-3 ms. This is my first Mac device and i am really heartbroken. I know nothing in the this world is perfect and am fairly patient but atleast hope Apple comes out with their thoughts on the issue and hope the brings us to their side.

Based on a quick test of booting from the Recovery Partition of my 2013 MBA and then pinging my local router, it would appear the 1.0 software update from Apple is indeed causing the wireless latency issue. When I ran a quick ping test, I was experiencing 2-3ms consistently vs. the 200+ms I have with the 1.0 software update for the 2013 MBAs.
So... others are welcome to also test their own MBA by booting from their built-in Recovery Partition (restart your Mac and hold down the Command and R keys). Then launch the Terminal application to try pinging your router or access point and see what your ping times are.
The only thing I'm now debating, is whether to back up my personal files & restoring my MBA as new from the Recovery Partition, or wait until Apple releases another software update for the bugs in this Broadcom wifi chip. As I wasn't expeiencing the wifi connectivity drops before the 2013 MBA 1.0 software update, I'm fine with rolling back to that driver for now. Hmm... decisions, decisions.
Then again, I suspect someone will extract the older wireless driver from a MBP and provide a method to roll that back into an updated MBA, as others have done it before until Apple fixes the issue...

I posted yesterday on this. I restored my MBA to the earlier version of the Broadcom WiFi firmware (.22) from the 1.0 update version (.35) and my ping times went down to under 3 ms from 30+ ms. For me that was the right thing to do but then my MBA has never exhibited any of the problems discussed here so it may not apply to other folks whose machines are not working properly.

I hear ya. As someone else commented, I think the network engineers at Apple and Broadcom got a little overly aggressive in remedying the wifi connectivity issue with the newer .35 driver, and accidentally introduced this wifi latency issue.
As I work at Cisco and know how tempermental wireless networking can be (an understatement), I know how it can take a while for the network engineers to have a stable fix in place. That said, I'm leaning towards rolling my Mac back to the .22 driver one way or another, for the time being.

If its a new MacBook Air, the easiest thing to do is boot from the Recovery Partition that is built into every MacBook Air now (by holding down the Command and R keys when restarting), and following the steps to restore your Mac as new. Just make sure you back up any personal files you might have created on the Mac to a USB thumb drive or some other device first.

Might also note the 10.8.5 OS update is probably imminent and who knows what kind of WiFi machinations they might have in there, including incorportorating the 1.0 update. So if using the Recovery Partition method might want do apply now before the 10.8.5 rears its unknown head.
To be fair, 10.8.5may also have a more permanent fix but nobody knows at present.

Yeah -- excellent point. For someone who's been in the tech industry for too long, I usually hold off on installing the latest releases until I see how it impacts others... just wish I did the same for the 1.0 update. Doh!

Notice to all of you concerned about ping values: if they were ok before the update that is good news, because it means it is software related and an update can fix the issue.

Guys i have 0 issues with my new macbook air 2013. No drops no slow speed and if i ping i get:

25 packets transmitted, 25 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 1.664/2.917/4.083/0.655 ms
I think that these nunbers are OK but i have installed 1.0 patch and i get about 40-80.000ms so i think the problem is patch. I have reinstalled OSX and now i get 0.500ms again.
So, guys, what do u think, is my macbook air affected? I can return it and get full refund but I'm not sure if my macbook is OK or is affected with that issue.
Please help me, don't know what to do, thanks!

They're all effected. Prior to 1.0 patch, people seem to be having random problems connecting to certain wireless routers. After the 1.0 patch, the connection speed is erratic and unrelable.
Currently Being ModeratedAug 25, 2013 10:03 AM (in response to andyman2)
I restored my OS-X and the timings has gone back to
306 packets transmitted, 306 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 1.480/3.387/23.638/1.867 ms
So the update definitely made the pings erratic .
