Q: New Macbook Air - wifi connectivity problems

A good thing to try is ping the router's local IP address. That will give you a better idea of the problem than just finding that the internet isn't working.

Unable to ping router when the issue happens. The signal strength shows full, but there is no Wifi conntectivity.

BTW, I change the encryption protocol on my router from TKIP to AES about ten minutes ago... so far, so good. This might be a fix.

Everyone with this issue -- check if you are using TKIP and change to AES. It's easy to configure in DD-WRT.

So far so good for me.  This is a temporary fix so long as I don't run into any other routers using TKIP!

Thanks for the good find!

Hello everyone!

I just sold my 15 MBP, and was about to order a new MBA.... When I saw this news!

Not only I think I'm gonna wait until it's solved, it just reminded me that I have the same problem on my ipad mini!

Logged on an airport extreme 2012, It's got exactly the same wifi problem, which can only be solved by a turning off and back on...

Related problems?

I posted the same fix, it worked for me too. It is indeed a temporary solution as you can't change the router encriptation of every network you use. Let's hope this gives Apple some clues and they work on a software fix... if this is not hardware related.

Which router models are you seeing the TKIP issues with ?

Can you ping your router ? That will tell you if your connection to the router is good. If that is good, then the issue is on your WAN side with the router.

Run the new Wireless Diagnostics in 10.8.4 and that should also help you troubleshoot your issue or give you more insight.

What is the issue you are seeing and what router are you seeing it against ? Use the Performance panel ( under Window->Utility) in the new WIreless Diagnostics tool to get an idea of how good/bad your signal quality is.

In my case (MBA 13" 2012, 10.8.4) and many other cases mentioned in this thread, ping does not work.

I found an update in the appstore yesterday, and after innstalling it I havnt experienced it again. But havnt been able to play as much with it either. The biggest problem for me occured when downloading large files like WoW and Dropbox.

I've been lurking in this thread for some days now and a lot of the suggestions here got me to a point of hours of continued wifi connectivity (from max of 10 minutes initially) up until I start downloading big files, then it just stops.  What resolved my issue was downloading the new firmware of my router.  I thought my router's firmware was updated (I was using the router interface) but when I searched the router's site, they had a newer one.  I know this might not help most of you here but it might help some.

I just had a visit by a service expert (for Apple products). Funny thing is, he used the same MBA model (2012) as I do, and - had exactly the same connection issues (wifi was generated by an Airport Express of 2012). While my iMac, iPhone etc. had perfect internet access the two MBAs lost connection to the internet repeatedly (while wifi connection with the other Macs persisted(!), just the internet got down).

Conclusion: Most probably there is a bug in one of the subsubroutines that manage internet access over wifi specifically(?) for the MBA. If a wifi environment doesn't make use of this subsubroutine everything is fine, if it does you have problems.

Apple, you have to do your homework. Now.

I would not consider Gizmodo a reliable source on anything.

Is anyone using the new Apple 802.11ac wireless router with the new MBA and is it working?

I can understand people's frustration.  Apple has a real history of wireless issues so you would expect better testing.  I was planning on getting a fully loaded MBA but waiting now.  I expect a patch will be out to address this issue.
