Q: New Macbook Air - wifi connectivity problems

Hey guys,

 

Hope someone can help?

 

I have a brand new Macbook Air which is able to connect to the internet for just a minute or two before suddenly it drops out. This is even though the signal still shows at full strength and all my other devices are still able to surf the net as per normal.

 

This device is straight out of the box so no 3rd party applications have been installed. I heard that the wifi has been upgraded to 802.11n on this machine, could that be an issue?

 

Do i need to return the machine or is there is a software fix for this problem?

 

Thanks heaps!

 

Vicky

MacBook Air, iOS 6.1.4

A:

Have you cheked if your Netgear router has the latest firmware ? What model number is it ? Your RSSI,Noise, Tx rate etc. look good. One thing you could try is switch to a different channel, say channel 6 and give that a shot.

 

Can you copy paste info. from your /var/log/system.log info around the time frame you see the drop ? I can take a look and see if it helps any.

    Since it appears Apple is aware of this issue, for all you posters if you have a WiFi issue you should call AppleCare and ask them if you can get the fix that some guys have been mentioning here. Maybe that will help you out...

    My new MBA is connected to wifi through AirPort Extreme when at home.

     

    I travelled yesterday and connected to public WiFi in Munich airport - no problems and it was FAST.

    That problem fixed ehh? Wonderful...

     

    Now once they fix the OTHER PROBLEM in the Mac Air which is software, that being the TCP window size would not scale beyond 64KB meaning on 802ac

     

    TCP window size defines the amount of data that a server can send before the client has to acknowledge that the data has been received

     

    Meaning on 802ac (5Ghz) the Air is maxing out 17 gig per second in Mac OS, this problem is limited to OS's Wi-Fi networking stack……so people are getting average 60% or so faster over 2012 Mac Airs.

     

     

    Whereas when bootcamped, the same air is getting 47 gig per second..  or 158% Faster

     

     

    There is a conflict in the Max OS with the next generation 802ac

     

    When the OS is fixed to get FULL potency out of the new 802ac, its reported that they will be around “158%  faster than the 2012 Air”

     

     

    So, right now nobody anywhere is getting past 70% faster 802ac over 2012 models in Mac OS,…..but once this little OS issue is resolved, Air users will be getting 158% faster 802ac like the bootcamped 2013 Air that has diff. TCP than that of the Mac OS

     

     

    That’s a lot to look forward too, likely 10.8.5 OS update, Im assuming.

    I have bought new MBA (i7, 512 hdd, 8 gb) in Apple Store in Florence (Italy) and wifi connettivity wasn't good.

    Yesterday, I have changed MBA in Apple store with a new one, but the issue is the same. Probably, these new MBA have a common issue.

    Well, I’m still wondering while mine works. Maybe the Apple stores got an older batch than the one I got by ordering directly through the online store?

     

    What does a WiFi ‘system report’ give out? I have this:

     

      Software Versions:

      CoreWLAN:          3.4 (340.18)

      CoreWLANKit:          2.0.2 (202.11)

      Menu Extra:          8.1 (810.11)

      configd plug-in:          8.5 (850.252)

      System Information:          8.3 (830.5)

      IO80211 Family:          5.3 (530.5)

      Diagnostics:          2.1 (210.25)

      AirPort Utility:          6.3 (630.34)

     

    Buona giornata toscana

    I installed the update as well and it didn't solve my problem at all. There's no change.

    well... so far so good for me.

    mine is behaving well either on Apple APs and on a Linksys WAG120N configured for the "worse"... i.e. wifi is in Mixed mode,, WPA2 Personal, TKIP/AES, on channel 11.

    To say the final word, I'll have to wait for Monday, when I'll be back in the office, where dropouts were constant and security is WPA2 Enterprise.

     

    Since enabling my modem/router wifi (the WAG120N) that I've never used before having Apple Airport Extremes all over my house and connecting my MBA I have NO dropouts.

     

    I'll get back to you on Monday...

     

    BTW, I've looked into the package I've downloaded from appleseed and apparently there's a kext inside... no firmware or else, so the problem - so far - could be traced to the OS.

    Glad to know I'm not alone in this issue. I kind of regret upgrading my laptop atm. Hopefully we can get a fix for this pretty soon.

    finally upgraded my Airport N to AC and now it works.

    I feel like Apple wants to sell more Airport ACs.

    Sooo.. You fixed nothing and spent more money... Sending them in the direction of the people selling you broken hardware.

     

    Great choice.
