    Theres a way to test that theory, as a ham radio operator and learning good bit about frequency and radio signals, ....does someone have a way to test if their new Airport Extreme is shunting to 5Ghz most if not all? surely there is a check for this.


    OR, is there on the Air, a wattage wifi check 2.4 ghz and 5ghz.



    If one is at the limit of range for communication, it makes a LOT of sense that 2.4ghz public wifi is an issue whereas Extreme dual band is NOT.


    Can someone do a dual old Air next to a new Air side by side and check input signal strength and also output in milliwatts.


    Additionally is the new air going nearly exclusive on 5Ghz, since 5Ghz has better GAIN thru walls and distance than does 2.4ghz

    i disabled the security on my motorola sbg900, now i've been online for like 12 hours
    not a solution but it's something

    I would love to know the answer to this.  I am on the road and have not had time to set up boot camp to see if there is an issue.

    Try re-enabling it, but making sure it is AES and not tkip.

    That means it would be fine under windows?

    Seems my WiFi issue is peanuts compared what I've run into today.  I've only had my Air for 2 days and all of a sudden today it's basically bricked.  Out of nowhere, it's now having crazy graphics glitches and kernel panics after every reboot.  FML.


    Here's a video to demonstrate:

    Ohhhh you should bring back to apple you can prob get a new one

  • PlotinusVeritas Level 6 (14,725 points)

    I was told by a Apple rep at a local apple store that "contrary to 14 day return policy" they would honor (these are his words) in fact 30 day return (if it turns out the problem is hardware related).


    Contrary to chicken little the "sky is falling" complaints about quality control or Apple verifiying hardware before shipping, I dont believe that whatsoever. Apple does extremely extensive testing on their hardware before shipping.


    However that being said, wifi and networking is to a GREAT extent not based in the hardware itself whatsoever. Rather in ISP protocols, wifi signal wattage, communications protocols, base station varieties which exceed near infinity...and on and on.


    That Apple Inc. isnt claiming "any problem" with the new Air is nearly entirely correct sensibly, since this is likely a simple OSX handshake to wifi fix, or firmware fix, or wifi firmware instruction to increase power output; and therefore is not a hardware issue related to any and all components within the Macbook Air.


    Having worked for a large multinational hardware company, the hardware guys were ok happy go luckys.., but the networking guys always looked stressed, logically so, when youre talking WIFI and networking, your dealing with maybe about 20% hardware side issues on its OS or fimrware..... and 80% infinite router and basestation configurations that boggle the mind.   That 80% is not something anyone should fault Apple for, rather there is no really down the line standard super-standard for wifi communication between 10,000X devices and 100,000X routers and base stations.


    I dont envy anyone who tries to diagnose wifi / routers and make any hardware comunication 100% on such diverse networks and protocols.

    Add my name to the list. 5 minutes out of the box and I was having wifi issues. It shows a full signal and even an IP address but I can't connect to the router ( or any other web page. Renew DCHP lease seems to be the quickest solution. I can't find any pattern to it. Sometimes it's after 5 minutes, sometimes 30.


    Using a WRT54GL router.

    All other devices work fine.

    Problems started out of box.

    2013 1.7GHz i7 8GB 13" model


    Hope it's an easy software fix.

  • p0ttyp1g30n Level 1 (0 points)

    I'm back today after being back home, where I have a full-Apple wifi setup.

    At my place my new MBA Haswell didn't fail wifi once! I've connected it to an Airport Extreme (previous model) to the 5GHz band.

    I'm unhappy to report though that the fix I suggested in my previous post didn't stick... today at the office I'm back to square one, but I can give you all a slightly deeper insight.

    At work, we run a wifi that uses 2.4GHz band, channel 1, WPA2 Enterprise security, authentication TTLS.

    My MBA disconnects from this wifi once every minute sharp! You could set you watch on this!

    The fun part is that nothing has changed in my office since yesterday, and I'm sure the connection, after my "trick" of removing/reinstalling the wifi service was working fine. There's a timer that shows the time your Mac stays connected and authenticated to a WPA2 secured network and I've seen that counter up to 40+ minutes... today it resets every minute.

    And the trick doesn't work anymore...


    And it does like this (i.e. disconnection every minute) also from another wifi we have, using the same parameters, but different security (WEP 64bit), so we NEED Apple to look into this matter, or we're screwed...

    Can anybody who is using Windows 7 in boot camp advise if they are having any wifi issues while running Windows?

  • Vinencre Level 1 (0 points)

    The second beta of OS X Moutain Lion 10.8.5 is out, and Apple ask to test wi-fi particularly:


    Someone can test this ?

  • PlotinusVeritas Level 6 (14,725 points)

    Im digging more and more into that nobody is having ANY issues on 5Ghz, regardless of Apple base station or non-Apple


    rather those with issues are ONLY getting them on 2.4ghz


    Anyone game to confirm this?  If proven so, then this smacks of wattage idling on 2.4ghz (for power saving).


    If someone is getting 1 min exactly dropouts as reported on 2.4Ghz, but never any on 5Ghz, then this seems to be an easy firmware update.


    Namely adding to that conclusion is keeping diagnostics open on 2.4Ghz constantly making dropping wifi issues "resolve" or halt,...that further confirms some kind of power or idling issue when communicating in 2.4Ghz.

    Ok guys..

    so, at home, we have TP-Link TL-WR340G..
    My problems solved, after I resetted it..everyone had problems .. PC, iPhone, iPad, Macbook (aluminium 2008 late), except me..I had to take it to Spolnet (Our ISP) and they setted it, I have had no problems!
    hope it will work still, I'm uptime about..10-12 hours..

  • themechanic152 Level 1 (0 points)

    I do get dropouts on 5ghz.
