Q: New Macbook Air - wifi connectivity problems

If it was me and it was within the 30 days I'd tell them to give me a replacement to see if the problem is fixed.

Had a genius appointment the evening.

Of course all was fine on their wifi.

Diagnostic did not show anything.

They replaced the MBA.

Went online on the new one at home and before I even put any of my data etc on, just going onto the web, wifi keeps cutting out. This is insane!

Then maybe your Wi-Fi is the problem. Have you checked if there are any firmware updates for your router?

So funny, i've been struggling with this for a while. Eversince I upgraded my old Macbook Pro mid 2009 to Mountain Lion i'm having the exact same problems. Yet I tried everything without any succes; reinstall, firmware update, new router, operating systyem downgrade. Eventually I went back to the apple store and they told me that I had to replace my motherboard for allot of money. Since i'm waiting for the new Macbook pro I fixed the problem with an external USB Wireless Network Utility. Goodluck!

Well -

I have an Airporrt Extreme with latest firmware.

I have in my family here 2 Mac Book Pros, iPad2, ipad mini, iMac and 3 iPhones and all connect well without dropping ever.

Did you update AirPort Utility to 6.3? Check Software Update on the MacBook Air.

yes, 6.3

Has anyone checked what is output to the console log when the disconnection occurs? Hardware errors detected by the driver are output to the console log. Please paste the error message here then Ill tell you immediately if it is hardware because I've seen it before on macs and the first batch of iPad 3s had bad chips.

Just bought a new macbook air.  Came home to find out that I can only stay connected online for 1-10 minutes!  What's up with that?  I will a little while for a fix/announcement that Apple is even aware of the issue.  If nothing, I will be returning this computer.

Hi...at the risk of sounding dumb, did you delete your network from system prefs and then rejoin, log on with password again to see what happens?  I'm sure you probably have already tried this because you sound like someone who knows a bit about what you are doing. 

Thanks

I have personally tried everything mentioned in this thread, and nothing works to keep my new MBA connected to the internet on my home network.  I have verified all firmware on router( Linksys router) is up to date, but it still loses connection to internet, not to the router.  When I connect to iphone as ahotspot, it'll work flawlessly.  When I connnect to iPad as a hotspot, it works flawlessly.  When I connect to MiFi air card, it works flawlessly.  It only has issues on my home network.  I have connected 9 devices now to my home network checking for connectivity issues.  PC's, other MAC's, and numerous iDevices and none of them have issues.  This is the newest, and the most expensive, computer in the house and it is the only one having connectivity issues with the internet.  I'm not totally opposed to upgrading my router if it'll fix my problem, but I'm not willing to do it if I've gotta worry about wether it'll work or not whenever I travel.  That's the biggest deal breaker for me right now.  If apple can't figure out what's wrong real soon, I'll be returning this computer.  Day seven of owning it, so I've still got hope that they'll resolve it before I have to return it. 

Here is a summary of the issue most people are reporting:

- Issue is seen only on new 2013 MBA.

- Wifi signal is strong, connection shows connected, but Internet stops working.

- Only known way fix is to turn off wifi and then back on.

- Issue persists even when reinstalling from clean HDD.

- Issue persists even when exchanging MBA for a new unit.

- Root cause seems to be with 2013 MBA Wifi card not working correctly with certain routers.

I am going to try tweaking every setting I can on my DD-WRT router. Will reply later tonight with the results.

One person reported that flasing from DD-WRT to Tomato fixed his issue. I don't want to do this (my DD-WRT router has been stable for 5+ years), but I will try it if I have to...

I went back to stock firmware on my Linksys E2000, it was running DD-WRT.  Since going stock, it has not had an issue.

I also bought a USB 3 Ethernet adapter and an Airport Express, to hedge my bet   If everything stays stable over the weekend, I will keep it.  If not, I will return it and wait for the fix.
