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

I had this problem both with a Motorola SBG6580 Wi-Fi Cable Modem, and with another one that I do not know because it is operated by the university.


An apple technitians pointed out to me that the noise to signal ratio is high according to one of my wifi-diagnostics results. This might be the cause of wifi drops at least sometime, and I can imagine that the bluetooth makes it even worse. But it does not happen all the time.

agreed. I found out about this problem because my ssh connections have been terrible this whole time since buying my MBA. ping times are all over the place. Comparison:


Raspberry PI running Ubuntu and is 5x farther away from access point (brand new Airport Express) than my MBA as well as being in a closet:


--- 8.8.8.8 ping statistics ---

40 packets transmitted, 40 received, 0% packet loss, time 39057ms

rtt min/avg/max/mdev = 36.715/40.090/57.343/3.411 ms


My MBA 3 feet away from my brand new Airport Express:


--- 8.8.8.8 ping statistics ---

71 packets transmitted, 71 packets received, 0.0% packet loss

round-trip min/avg/max/stddev = 33.232/100.686/306.457/60.611 ms


standard deviation of 60 ms???! Dude wth?


Mavericks

Card Type: AirPort Extreme (0x14E4, 0x117)

Firmware Version: Broadcom BCM43xx 1.0 (6.30.223.154.45)

additional info...


i have a Chromecast connected to a TV which i stream netlix/hulu+ from a Dell Vostro 17" running Win 7 Pro.


when the MacBook is powered up and on the LAN, the cxn between the Dell and the Chromecast will disconnect and i will have to reload everything but at that point everything is waiting for timeouts all around and it takes a while for everything to load back up.


i'm of the opinion that the macbook is flooding the LAN with packets which is affecting its own functionality/performance as well as those of other devices on the LAN.


really really ridiculous that this thread is 127 pages with no solution.


do you know how much marketers would pay to get a 127 page thread on any subject ?!


oh also i actually did a fresh install of mavericks and the problem remained.


in the two months i've owned the macbook, the computer has hard crashed on me twice without warning, just kaboom it's rebooting like a motorcycle highside out of the blue. the macbook simply will not bluetooth pair with my iphone 5 (non-s). iphone has not had any problem pairing to car radio, andriod tablet, etc., only problem is with macbook. no biggie since i don't really need that functionality at this point, but seems pretty odd that a brand new macbook air can't pair with a relatively new iphone ?

ive have the mid 2013 mba since it came out, and only lately (maybe after upgrading to mavericks) have i seen poor wifi performance. At work i get random drops and loss of connectivity. Whenever my screen goes to sleep it drops the wifi connection.


Has anyone tried to exchange one more than 30 days old for this issue? I was thinking about trying to do the exchange and see if it helps.

Hi all,

I went today for the first time to the Genius Bar. No results. They run checks and said that they really didn't had much else to do than to scalate the case to the engineers and that they will contact me again in the next couple of days.

I am tired of this issue also and seriously considering to shift back to windows too.


Those that have been able to have replacements in the store after the first 15 day period have any recomendations of how to address the geniuses at the bar to have a replacement to?


Thanks,
