    Does anyone have a handle on this, definitively?

    It doesn't appear that the July 18 update works for everyone.

    So is it hardware or software? And who has the expertise to make that determination?

    The interference thingie somehow looks like a hardware issue. Might be it's just my machine, might be my headset is flaky and has radio on frequencies it shouldn't - trying to sort that out with a friend's MBA (mid-2012) tomorrow.

     

    For the latency stuff, it feels like software/driver - but I'm no expert here.

    I should note that the headset is NOT connected to the MacBook itself, but to a phone nearby.

    newbietech46 -

     

    I am engaged with Apple engineering on this matter and until something changes, I am still recommending the options I listed in my post on page 99.  I would also recommend taking a look over some of the other posts since then.

     

    Regards.

    Have done the driver Rollback from 10.8.5 version to .22. The results are as follows:

     

    10 packets transmitted, 10 packets received, 0.0% packet loss

    round-trip min/avg/max/stddev = 2.452/4.975/11.982/2.411 ms

     

     

    Ping test with .35 driver min 1.476, avg 2.269, max 5.082 and stdev 0.097. BCM 43xx 1.0 (6.30.223.35)

    Suffering from VERY intermittent wifi.

     

    Just got back from the Apple Store where I had a Genius Bar appointment and they ran a diagnostic tool called "Mac Resource Inspector" on my 2013 Macbook Air and of the 20ish components it inspected it QUICKLY flagged my wifi card as bad.  Free replacement is on order and should arrive in a few days, and they'll swap it out in-store.  Will it fix it?  Dunno.  Will I have ping issues?  Dunno.  But I was heartened to see it flagged so fast.

     

    Of course I cited this thread the moment I walked in, so maybe I am more knowledgeable than average so they went striaght to the replacement card.  Let's see what happens!

    This is VERY interesting.  Please, please, let us know what happens after the card is replaced.  If it DOES fix the problem, I am taking my Air into the Genius Bar straight away and showing them this in hopes they will do the same.

    Still having wifi drop issues. It was working "okay" on my home network (WPA2) with ping values all over but at least I was able to browse! but this was only until recently I used my machine on another WPA2 network. There it was "okay" too with occasinal lags and when I came back into my home network, I felt like I was back to the same spot where it all started. Wi-fi drops like crazy. Previously, I had tried all methods listed on this forum. Rolling back to 0.22 driver, installing new OSX etc.,and after doing all those, at least I was able to browse. Thanks a ton to all the info. posted here. Now it's back again. Its frustrating that such a costly laptop wouldn't perform a basic wifi functionality.

     

    The only thing which I haven't tried is updating my router and I don't think is a very good solution because I can't expect all routers wherever I go to be "AC" top-end high class routers plus it costs me 180$ to buy one. That's why I spent so much on a laptop expecting it to be good. The machine needs to work on all routers. And c'mon when my iPhone, MBP 2010, Dell laptop, Hp laptop can capture good signals from my same router why not this machine? This is a huge disappointment.

    Interesting.  It would be helpful for troubleshooting purposes, if you defined what you mean by "intermittent WiFi".  The more specific on what you were encountering and in what settings, the better, as that will help folks from over-generalizing the symptons with their own machines and network configs.

    Heya Headcase,

     

    I haven't bothered with the ping issue because my wifi has been so bad I just want the thing to work, who cares about speed. :-p

     

    The intermittent aspect has been the same thing some others seem to be seeing... Put the computer to sleep, and on wake it hunts and hunts for a network.  Sometimes it finds one and connects fine, sometimes it sees networks around it that are known and doesn't connect, but more often than not it doesn't detect any (none in the dropdown list).  I have woken it from sleep, seen it hunting, hit the dropdown and see a familiar network checked as though connected, and when I try web browsing it works even though the icon shows it continuing to hunt indefinitely. Turning wifi on and off never works, only a restart helps (and it helps pretty much 100% of the time).

     

    Worth noting, I had the v1.0 update installed, and pre-10.8.5 it would just drop wifi randomly every now and then without a sleep period to trip it up.  Post-10.8.5 the random drops seem to be gone, but it has issues after sleep a LOT more (60-75% of the time?).  So...software changed the behavior.

     

     

    Firmware Version:          Broadcom BCM43xx 1.0 (6.30.225.29.1)

    Thanks for the detailed info.  Will be interesting to see what you encounter upon getting another machine. 

     

    If Apple has a test in place to flag this latest Broadcom AC radio chip for irregularities, it might be worth others experiencing dropped connections to take theirs in for testing at a local Genuis Bar, regardless.

     

    As for the latency bug introduced with the newer wireless drivers, its real and its substantial.  But that will likely be resolved via an updated driver.

    I feel your pain.  Per my last post, it certainly can't hurt to have a local Genius Bar run their tests on the Broadcom chip.

     

    As for any pains of upgrading your router, albeit a side note:  its worth noting that the list of routers I tested with includes some older N-series routers that are top-rated (e.g. the venerable and now discontinued Cisco E4200 v1), and can be picked up on eBay for pretty cheap, and yet still provides you many of the added benefits I identified earlier.  I tend to scratch my head when someone is running a brand new mobile device connected in their home to a pokey router from 15 years ago that doesn't even have a decent CPU or solid uptime.  But I digress.

     

    Good luck.

    FWIW, I use a Cisco E4200 V1 at home with my 2013 MBA and have zero problems.  (Of course the MBA runs perfectly out in the wild too.)

     

    The 4200 jas GB Ethernet and I have three other Macs connected to it that way in addition to the WiFi which supports the MBA as well as iPad and iPhone.

     

    Very decent router.

    stumbleone,

     

    It is great to hear about your lack of problems. I too have not been affected with any issues of which I am presently aware. (But, I do only rather simple things with my computer, compared to others posting here and have few devices in the house to compete with the MBA--just an ipod touch and a stalwart 2006 MBP with various new parts, which sits nearby, still running but very slow.

     

    I (and perhaps some others) would be keen to know whether you are still using the .22 original driver (without the patch and without the driver found in 10.8.5)? Or with 10.8.5 rolled back to the earliest driver for MBA?

     

    I have not updated or patched since this issue arose but one day soon, I suppose I will need to. Is there any problem jumping up from 10.8.4 to 10.8.6 one day, without 10.8.5?

     

    Thank you for any further details about your software upgrades for your MBA.

    The MBA is a June model, 13"/i5/4G/256G.  Right now I am running 10.8.4.

     

    The machine has had problem free WiFi in a wide variety of places around town ever since I got it.

     

    When the 1.0 patch came out (with the .35 firmware) I somewhat reluctantly applied it and then based on the discusssion in this thread I tried the router ping test - very erratic results even though I could see no impact on internet performance.

     

    I reinstalled the .22 firmware and my ping test went back to the 1 - 3 ms range and still problem free.

     

    My plan is to hold off installing 10.8.5 given the discussion in this forum.  The 10.9 Mavericks system will be out relatively soon and I will review the situation then.

     

    I don't know if there will ever be a 10.8.6 but in any case I wouldn't expect to install that, waiting for 10.9.

     

    Hope that helps.
