    Definitely not attributed to old routers. Mine does it with 11ac.  Be interested of you ever have a chance to try the ping test against your router.  Wondering many of these airs are out there that can hold a connection without building up latency.  Think there's 1 so far. ...

    hello guys i just go my new macbook air 2013 i5 1.3 4gb ram 128gb hard drive at the apple store in anarbor michigan well i got a old g router and the mac connects perfectly yes the ping times are never 1ms there between 80&100s and im not 10 feet away other than that its pretty good u guys think i should install the update for the wifi

    Prior to this, I had only tested ping as part of ISP speed tests.


    Did the ping test. As expected, erratic, e.g.:

    --- ping statistics ---

    39 packets transmitted, 39 packets received, 0.0% packet loss

    round-trip min/avg/max/stddev = 1.723/35.772/101.711/33.858 ms


    I have .35 firmware. I installed the wi-fi fix a couple of weeks ago - even though I didn't have trouble (why change a winning team?). Still don't have trouble (Didn't change a winning team).


    Other than erratic ping, that is.


    So, if both those with working MBA 2013s and those with non-working MBA 2013s have erratic ping results, that does't tell me much.


    Have anyone posted ping results from a PC with an AC wi-fi card? Or just from PCs with wireless-N?

    Experience very similar to yours with a "no-problems" MBA.  I installed (mistake!) the patch to update to .35 firmware, did the ping tests, and got these types of results:


    2013 MBA 13"/i5/4G/256G - 1.5 / 54.5 / 36.5  min-avg-max


    Bit the bullet, after some flailing around reverted to the .22 firmware, reran ping tests.  Now am getting these kinds of results consistently:


    1.2 / 3.3 / 2.5


    Much, much better.  Performance still excellent in connecting, staying connected, etc.


    My conclusion is that for fully functioning MBAs the patch is not a good thing.

  • andyman2 Level 1 (0 points)

    Unfortunately buffest I think the working MBA's have consistent ping results...  What apps/services do you use on the MBA?  Wondering if its something different you're doing.

  • buffest Level 1 (0 points)

    How did you revert to .22 firmware? Time machine back-up, or is there an easier method?

  • buffest Level 1 (0 points)

    I have very few apps. No services running. Erratic ping doesn't really bother me until I see any real life performance issues. Of course, I will probably revert to .22 firmware if that improves the ping.


    I should probably test a PC on my wi-fi as well, though.

  • andyman2 Level 1 (0 points)

    do you use skype or a service like that?  that's where the erratic network connection can really hamper.  browsing, or non-time critical network actions don't show it up.


    Definitely try the PC in case its your own wifi, but experience says its probably the Air.  Everything here gets a consistent ping in the region of +/- 5ms.  The Air goes up to 2 seconds in extreme cases....

  • stumbleone Level 2 (290 points)

    No Time Machine, but fortunately I had a cloned back-up copy of the system before the patch.  So I just erased the SSD on the MBA and loaded the cloned backup.  Had to re-update some softare, etc., not that big of a deal.


    If I didn't have the cloned backup I was going to try reinstalling 10.8.4 and see if that would bring back the .22 version.


    If that didn't work, not sure how else to do it.


    FWIW, no data, but I'm inclined to believe the .35 patch introduces some timing delays to gloss over other problems with WiFi.  I don't think it's a "clean" fix yet.  The fact that I and other people have machines that don't exhibit the WiFi issues is a conundrum.

  • andyman2 Level 1 (0 points)

    I agree.  Especially as the software update looks like it modifies the firmware, but its actually only driver related.  If you run Windows on through Boot Camp on the Air, the lag is very much there (even more so), so it definitely needs more than just a Mac software fix.

  • buffest Level 1 (0 points)

    No skype. I use a music streaming app where I have lost the connection one or two times, but that's a known issue on that app, I believe.


    I've tested a bunch (15-20) of high quality video (not HD) streaming simultaneously. Troublefree. That may have been before I installed the update, might try that again.


    The connection issues people are reporting are a lot more severe than erratic network connections, aren't they?

  • andyman2 Level 1 (0 points)

    Music streaming and video streaming will generally cache ahead to stop the video/music stuttering, so you shouldnt expect to see any disruption, especially if you're on an 11ac network with decent internet.


    The update I believe from prior reading, was meant to fix certain access points which it had trouble joining and staying on.  So some advice has been if yours works with the access points you have, don't update.


    The connection issues which people are currently having appear to be around the connection being ok, then suddenly either dropping packets or having lag (could only be for a second or so).  This shows in the ping test.  The reason why this is a big deal is it means VOIP (skype etc) nevermind video chat can be unusable.  Accessing windows shares can become unuseable.  Remote Desktop etc can be unusable.  Essentially anything which requires real time data is useless/unreliable.  So a lot of people who use this for work which includes any/all of the aforementioned (myself included) have a very expensive paperweight.

  • buffest Level 1 (0 points)

    I understand these issues regarding real time data requirements. But my understanding is that a lot of people have had trouble even with surfing?


    Guess I'll revert to the older firmware.

  • andyman2 Level 1 (0 points)

    Maybe, but they'll probably be having a lot more timeouts and packet loss on the ping test rather than just a slow repsonse.

    My girlfriend just got a MBA and, guess what?, she is experiencing the nasty wifi problem.

    I haven't gone through the whole post, which admittedly is too long with its 80 pages, so I may raise a problem that was already touched and solved.

    She can connect to her WiFi network, but internet is not working. Moreover, she can not even ping her router. IP address is correctly assigned (and the problem persists even after manual settings) but 100%of the packets get dropped.
