If you're not comfortable mucking around with the configuration of your router, etc... best to consult at friend or local specialist. That way, you can ensure the steps you're taking are properly resolving the networking issues, as opposed to making them worse.
As an FYI, I've tested the original .22 wireless driver for the 2013 MacBook Air with various best-performing Netgear series of routers that have N class radios (e.g. WNDR3700 and WNDR3800), and they works fine.

It's hard to advise here. Aside from the issues (wifi especially) the Air is a great computer. Light, well made, fast etc. Even if you get maximum SSD it's still small by hard disk standards but you do get very quick performance. Not so good for gaming but probably doable for lighter weight games.
That said, you never know what Apple is going to do, especially in the post Jobs era. Mine worked well as soon as I bought the Time capsule and I use AT&T's Beam dongle for my on the go connectivity. I do have an odd problem where I get what seems to be crashes which seem to relate to power saving features (I had to turn them off). They may interrelate with the Beam's connection, I don't know. I guess I'd advise waiting a few months, maybe even a while longer to make sure they have the problems taken care of.
It's up to you really. There's no doubt it's a great computer ... IF you don't run afoul of their bugs. Maybe the previous version of the Air would be cheaper and safer. I have a 2010 version too that I have't given away to my family yet and the truth is that aside from the backlit keyboard on the new one (which I like) I can hardly tell the difference between the two machines. That might give you some time to let Apple try to put it's house in order.

carbon_dragon: can you explain what your average usage of the machine is ? I would like to understand your "I can hardly tell the difference between the two machines". I've also got a mba 2010 and was looking forward to replace it.

I'm a software engineer but I don't really use it for my work. I use it as an iTunes database, I use the kindle app and Safari for internet, I keep my checkbook there, etc. I also have a parallels Window 7 virtual machine to remote into work (I'm a Windows developer). I use it for limited photo editing, but not heavy.
It definitely has a faster CPU than my 2010 and a better graphics processor but not so you'd notice if you're not doing high CPU/GPU activities. I like the bigger SSD and the increased battery life (and the backlit keyboard).
All that said, really you hardly notice the difference. If I was developing code on it I might notice quicker compile times and I'd probably notice the difference if I were doing video editing (though even the new one really isn't designed for that). The differences are incremental not revolutionary.
Really if you had them side by side you probably wouldn't even know the difference. Sad but true. One thing, with the Time capsule and 802.11AC, I DO notice that. The internet at home through wifi is noticeably faster (now that I have an Apple router).
The version of the Air between my old one and my new one also had the backlit keyboard. The Air is a great computer to use if you're not bitten by the problems, I think I can avoid them now with the new router and disabling of the power saving features -- but really it's not that great an improvement over my 2010 EXCEPT for the 802.11AC with the Time capsule and maybe the backlit keyboard.

I think there is a big difference. And that's battery life.
I'm a student and I commute every day to school and back 2h to 3h. I have some classes which require computer work. I can use University's computers (they are junk) or I can use my own computer. With my Windows laptop I got under 5 hours with Wifi off and under 3 and a half with Wifi on, just browsing and Office work. I don't like wasting my time, so on my way to school and back I try to do some school work. I constantly had to carefully calculate my battery time and often had to not use it during commute because I knew I was about to have 2 classes (more than 3 and half hours) where I need my computer. And a coffee at McDonalds after school for some browsing... forget it! My laptop was long dead by then.
With my new MBA this is all going to change. I can leave my home in the morning, keep it on 10 hours if I so desire, and still have some juice when I get home in the evening. For the way I use a laptop usually (Office and browsing ) MBA 2013 is the best choice because of the battery life and portability.

I have the wifi problem since I bought the macbook air 2013 (late june), sometimes I lose the connection and have high ping. At first I thought the problem could come from my router, but I try to connect my MBA at many places, and it's still the same, I got the wifi drop connection. I installed the .35 firmware from apple, I tried the roll back method from Orchetect, I reinstalled the OS... and no improvement. I notice that when I am on Bootcamp partition with windows7 or on recovery partition, I don't have this problem.
I love the MBA, it's an awesome laptop with good perf and truly fast, I don't want to trade it for any other model.
But I'm tired of the wifi problem...
Should I wait for 10.8.5 to see if the problem is resolved or not ? Has somebody tried 10.8.5 ?

Normally I'd agree with you and I do think I get a little more battery time. But with my power management kernel crashes I have to keep the power management turned pretty much off and after doing that, the benefit of the extra battery life is somewhat minimized. Also I have a core I7 which also is a big limiting factor (apparently) on battery life. So that is not really an advantage worth talking about for me. That said, it still lasts most of the day so i'm satisfied.
I'd rather have less battery and fewer OS meltdowns. Which kind of reinforces that this hardware and OSX version really isn't ready for prime time and who knows when Apple is going to actually fix them since they aren't even admitting to them. Did they EVER admit to the iPhone 4 antenna problem? Nol they just modified the hardware design for the 4s. So they may NEVER fix either of these problems so don't buy unless you can live with the problems the machine has now because Apple's tendency is to fix any problems in the NEXT model.
If I were doing it all over again, much as I like the Air, I'd have stuck with my 2010 or maybe upgraded to the next model and skipped this one. As long as I have it, I do enjoy the 802.11AC at home.
Currently Being ModeratedSep 2, 2013 9:24 AM (in response to carbon_dragon)
I think I'm missing something. Did I understand correctly and you also have power management kernel crashes? If so, is it because of what you use it for or is because of OS X, or both?

I just wanted to chime in again. Still no problems since downloading the 1.0 patch on my i7 Air. Here are my latest pings to router, through a wall and a couple rooms away.

In my case, the 0.35 driver seems to work just peachy. I never drop anymore at home on my grizzled Trendnet N Router, I consistently get 2.5-3.5 Mb throughput on that network. I have only used it a few times out of the house so far but no drops there either. I sometimes have no internet connections available after rebooting into Windows, but zapping PRAM fixes that every time, and the Air boots so quickly that it isn't really a hassle to do a quick PRAM zap. Well, except that you have only about a two second window to do the keystroke before the default set OS starts loading up. :-)

LeeBrunk, I'm glad you are happy with your wifi, but the ping results don't look like wireless to me. You must be pinging your own local IP on the wifi network instead of the IP of the router.
You can get your router's IP from clicking on the Wi-Fi icon, then Open Network Preferences... -> Advanced... -> TCP/IP -> Router.

Thanks for this excellent how to. I have now rolled back the .35 driver to .22 on my MBA 13inch and now have relatively stable pings for a short period of time, still alot longer than a model 2012 MBA 11 inch that constantly gets under 1.7ms to ping my router, but atleast way more usable.
However I wanted to bring something out that I have not seen in the 93 pages of this post and that is when running the likes of Candy Crush on Facebook, while still pinging my router, the response times dramatically increase. I'm getting latency times of well over 4000ms, for dramatic periods of time. Yet again on the 11inch hardly a fluctuation in the ping times when I repeat the same scenario.
This has me wondering if the issues we are seeing here is related to how Apple is handling the power saving functions and also I wonder if any other people can reproduce a simialr issue when running the likes of Candy Crush.
Currently Being ModeratedSep 2, 2013 6:10 PM (in response to raducan.mihai)
Here's what I experienced. I was running my MBA with the default power management features. I plugged in my AT&T Beam 4g dongle, and once connected, I entered I fired up my Parallels program with Windows 7. I then brought up IE and selected my company's remoting program. Once connected I'd last a few minutes and then I got a OSX kernel crash resulting in total fail of the OS. After doing that a few times I gave up, convinced that it was the Parallels. Then I experienced the same thing without windows but with the Beam still providing internet connection.
I noticed that the problem seemed to occur after the power management features tried to ... well do something, dim the screen, maybe spin down hard drives or something. I went in and started disabling PM features. After doing all of them so that it was running at full throttle, it was solid as a rock, but my battery life suffered. It's possible that the beam's 4g had something to do with it too, don't know. Very annoying though.
The combination of the two problems hasn't made me very happy about Apple's QC. Also I was havig the internet issue pretty early, but well after there were a LOT of posts about it on this forum. Yet Apple's techs on the phone never so much as suggested that they were having a problem. That didn't make me feel very good about Apple either. Why do I have the idea that there is some card hanging over all their phone techs that says "do not admit to any systemic problems with the machine?"
That's why even though fundamentally it's a great machine, I tend not to recommend it right now, at least till they solve the problems (hopefully before the next time they rev the computer).
