    I wouldn't say my Chromebook is 5x the performance of my 2008 Macbook, but it's way lighter and runs cooler. And NO darn loud fan noise.   I've said before it's not a full laptop replacement (yet) but for $200 this is an interesting learning experience re: Samsung and Google support,  100% cloud computing ecosystem.  I had reason to reset the Chromebook.  FYI, there is no need to back-up before a reset.  Everything is in the cloud. Right, I remind myself.  So after reset, Chromebook automatically re-synced.   All my apps, all my settings.  A small glitch taken care of by updating firmware. What was refreshing was tech support acknowledging my issue,  that it was 'known.'  

     

    The only thing not re-set correctly was clock time (wrong time zone)  and my login image (i took with built in cam but didn't manually upload to Google drive) but basically - I did a 'wipe' of the chromebook, reinstalled the OS, without a backup, and all my stuff was reinstalled.  This all took less than 10 minutes. As a 25 year Apple customer, backing up then wiping a macbook then reinstalling OS then reinstalling all my data would have taken hours

     

    Hmmm.

     

    Mr. Cook, are you listening?

    Yes, the MBA 2012 is affected, too - yet, less frequently. Search for my posts in this thread. It took me more than half a year of permanent troubles just to find out my MBA is the problem. And Apple has nothing to offer me (doesn't even acknowledge there is a problem...). Now I will return my MBA asking for a full refund - which is extremely cheap for Apple because I have spent several weeks of full time work in this problem. Apple completely f***ed this up. The biggest problem for me is, though, that I don't know what to buy instead since I do not want to leave my 10-years+ accustomed ecosystem. I can't tell you how frustrated I am...

    Howdy Rosember,

    You do not need to leave the current ecosystem.

    If mac_airbrick doesn't work as it must then you can take a look at alternative ways http://goo.gl/gpWqwr

     

    APPLE won't fix this problem, they are too busy with buying back their shares.

    I'm having the same issues as everyone else in this thread with my MBA 11" mid-2013. Poor wifi latency performance generally (I work over ssh a lot and typing at the terminal is uncomfortable to say the least, you type, nothing shows up, then a backlog of about 10 characters you typed suddenly all appear -- basically unusable). Wildly varying ping times, even after the 1.0 Software Update: anything between 20ms and 1500ms to a router that's standing right next to me. Luckily, I bought the Raspberry Pi kit not that long ago and it had a piece of gear in it that I previously had no use for: the Ralink 802.11 N tiny USB dongle. I found the MacOS X driver for it, and while the setup is kind of ugly (both the hardware and the software user interface), it does exactly what it's supposed to do. With the dongle, my ping times are now stable and are in line with all my other devices.

    I`ve kind of had it with Apple also.There is still no official acceptance of the problem that affects many of them...they are still selling them with the issue...and no matter what anyone says about helping you fix it-they can`t, and then will avoid your calls.I was promised high level support and to call anytime only to have my calls not answered or returned. This stuff needs to get out there in the mainstream, since being nice and going through proper channels is not effective.I believe selling known defective goods without offering a viable fix is basically fraud.....

    I agree. Apple clearly has an issue that they have tried to correct with a software update, apparently not completely successfully since people are still having a problem. We don't know if the problem (or problems) are software or hardware but I'm guessing it's at least partly hardware (or possibly a design flaw). It's very serious and I don't blame anyone for avoiding the model (or even Apple laptops for a while till either WiFi evolves so that the routers the MBA has issues with leave the market or they finally fix the problem). The mac sites don't seem to be pushing Apple, but Apple is incurring costs associated with all these exchanges so it's not like they're totally unmotivated. On the other hand since they're not admitting anything, it's hard to know when it's safe to buy.

     

    I'm lucky in some ways that though I experienced this, I had a solution that worked for me, even though it was an expensive one (Buying a 802.11AC Apple router). Since I rarely connect to WiFi except at home, and since I use an AT&T cellular modem when I'm on the go, it no longer bothers me, but the problem is still there of course. I wonder if this isn't an indicator that Apple might no longer be the company it once was with Steve Jobs. Perhaps that Apple is a thing of the past.

     

    I think Apple could explain this problem in detail by now, but they've chosen not to, either because it's too embarrassing to fix or because it's too expensive to fix, or both. But I see it as similar to the X-Box 360 Red ring of death problems. It will bleed money out of Apple (and trust) until either the 2013 MBA is a memory or until they explain what is happening and fix it permanently.

    Unfortunately, the buying an 11ac apple router didnt fix the problem for me though its quick when it works, but the latency peaks still occur just as frequently.

    Hi!

     

    Just to compare, I'm in the UK (I use Google as a proxy rather than my ISP) and with a fully functional June 2013 MBA 13" in the UK using a NetGear 802.11 ac (5GHz, Chanel 'auto') 6 meters away through an old Victorian 1 ft thick stone wall to google.co.uk, this is the average 'Ping' that I'm getting as I type now:

     

    • 0.0% packet loss round-trip min/avg/max/stddev = 12.233/16.002/20.456/2.838 ms

     

    Just for fun, same setup, but this time to google.com (wherever that is):

     

    • 0.0% packet loss round-trip min/avg/max/stddev = 13.531/59.979/167.037/49.186 ms

     

    Again, as I type this, Speedtest.net is giving me on my notional 120Mb/4.5Mb Cable from VirginMedia is giving me the following (remember I'm ~ 30 ft from my router with a 12" solid rock wall in between):

    Untitled.png

     

    Now, these bits of info show quite a number of things, but the main ones are:-

     

    1. If your MBA isn't working, A P P L E   M U S T   F I X   IT   N O W !!!!!

    2. I'm a lucky chap, 'cos when it works, this MBA is faster than anything else on the market (WiFi-wise)

    3. Pings aren't everything - they are sever specific from any given location

    4. The time of day and day of the week these tests are performed matters (it's 20:25 on a Sunday here in the UK)

    5. Having a good cable speed makes a difference

    6. Having a crappy WiFi speed is U N A C E P T A B L E  I N  T H I S  S U M M E R' S  M B A!!!

    Just thought I'd chime in and say that on this second Macbook Air I've been sent I've got exactly the same high round trip ping values as the previous people, just when pinging the actual router

     

    Four year old macbook is churning out about two ms

     

    New Air is all over the place, between 3 and 80ms

     

    And like the pictures posted previously, they're next to each other in the same room

     

    I would post a picture but it looks just the same as the previous ones that people have posted up.

     

    Balls.

    andyman2 Level 1 Level 1 (0 points)

    what do you get if you ping your router for say 20 packets?  Can you post the result?  If you look at some of the pings, they're to the local wifi router, thereby removing ISP connectivity.  And happening at the same time as another device.  Awaiting my new replacement MBA though I imagine it'll be the same....

  • 1,120. Re: New Macbook Air - wifi connectivity problems
    BevvyB Level 1 Level 1 (0 points)

    Just tried that. My Wi-Fi is called Wi-Fi and it just came up with a 'ping usage' table >

     

    sudo ping -i 0.2 -s 0 -S `networksetup -getinfo "Wi-Fi" | grep "IP address" | awk '{print $3}'` `networksetup -getinfo "Wi-Fi" | grep Router | awk '{print $2}'` >/dev/null

    usage: ping [-AaDdfnoQqRrv] [-b boundif] [-c count] [-G sweepmaxsize] [-g sweepminsize]

                [-h sweepincrsize] [-i wait] [-l preload] [-M mask | time] [-m ttl]

                [-p pattern] [-S src_addr] [-s packetsize] [-t timeout]

                [-W waittime] [-z tos] host

    What's your output of:

     

    networksetup -getinfo "Wi-Fi"
    

     

    When connected to your accesspoint it should look something like this:

     

    DHCP Configuration
    IP address: 192.168.2.10
    Subnet mask: 255.255.255.0
    Router: 192.168.2.1
    Client ID: 
    IPv6: Off
    Wi-Fi ID: 84:38:xx:xx:xx:xx
    
  • 1,122. Re: New Macbook Air - wifi connectivity problems
    BevvyB Level 1 Level 1 (0 points)

    Yup it looks just like that.

  • 1,123. Re: New Macbook Air - wifi connectivity problems
    richard_vd Level 1 Level 1 (0 points)

    Well, then I don't know why it doesn't work for you. It works for me!

     

    But since you already know the IP of your router you may just as well use this simpler syntax:

     

    sudo ping -i 0.2 -s 0 192.168.2.1 >/dev/null
    

     

    (you should replace 192.168.2.1 by your router's IP)

     

    Does that work for you?

  • 1,124. Re: New Macbook Air - wifi connectivity problems
    BevvyB Level 1 Level 1 (0 points)

    Yup, it works!

     

    Got the script running in one terminal window

     

    Opened another terminal window and pinged the router....
