WiFi Issues With MacBook Air

No, I have a plain old ASUS WL-500gP. So far, connection is good on 11th channel with WPA2 enabled. I can't say whether speed is higher with BT on or off, but it is just enough for me.

Still, I can't connect to a secured 802.1x network in office with BT on. Authorization timeout :(

AFAIK, router in my office is on channel 9. I'll ask our administrator to switch to 11 if it's possible.

Not a news, but i tryed windows with bootcamp and, like already told.. sadly, works perfectly, today I reached 1MB/S downloading some stuff.. i never, ever saw this speed on mbair.. connection is stable and strong, even going far from AP (before was for me a big issue, just 2 rooms away connection getting very,very slow allowing to browse only html pages.

I change to apple this year with this MBAir, and I would expect, as stated by apple itself, just a great experience.

After 2 weeks a key jumped out from keyboard.

After 1 month system became soooo slowww (yes, yes.. my blame) and i decided to reinstall Lion, and havin such problems with wifi you can imagine what was use their "internet restore".

After 2 Months it began, sometimes, to not charge laptop randomly.

Just to mention, my HP printer seems not to have drivers for apple....

and above everything, never had normal wifi.

Ok, maybe i'm unlucky, but about wifi... i don't kow, if this is the "welcome in apple world", i think that i will soon take the train back to Redmond...

HEEEEEEEEEEEEEEEEElp. My mac book air has been upgraded to LION. Now it connects to public routers OK but doesnt connect to the internet. At the same location my iphone 4 and Ipad access the same public wifi and get internet access!

My MBA does work Ok at home via an Airport Extremme wireless router.

I have spent days trying all sorts of solutions but yet to find one that works. Does anyone have a solution. Or failing that can I revert to snow leopard, which worked Ok everywhere

Read the "book" (Isaacson), drank the koolaid...errr, i mean bought the mba. major uptick for someone running win98 on a 12 year old beige box out of the dump....movin' on up! so guess what? big dough for no go. mba went back to cupertino, or asia, or wherever the heck. money went back to bank, and i type this on an brandy new $350 kid toy asus from best-buy. works just fine, and will get thrown in the pile behind the barn with the beer cans when it wont. problem solved indeed! skeet me a tweet when yer heads come out of your poos fan-boys, eh?

Hey, thanks jimmy, that's really helpful! Thanks for your constructive input. Seriously, do you get a thrill out of being a troll?

Anyway, for those talking about switching channels on the router, I haven't had any luck with that on my end.

SOLVED... Tried all the usual, deleting the confg folder, renewing location and dhcp lease, turning wifi on/off, restting safari but none of these worked. What die was applications/utiliies/Keychain access/keychain first aid. The run verify and repair. Can now get stable internet access at all public wifi zones I have tried. Worked for me and didnt involve any deletions or work arounds...

I gave up on Lion and reinstalled Snow Leapard (10.6.5). All is working fine now...

One thing I noticed, is when the wireless adapter supplied its MAC address to DHCP it would be something like 4d4443 instead of the conventional address (e.g. 78ba29d250cb).

Like that troll bit. My fit of pique resultant of being gulled overrode my fundamental reserve. The MBA was a beautiful device, a genuine thrill to unpack and turn on. That it could not function with well established protocols was extremely dismaying. I feel strongly that this is an issue of an an entirely different nature than say: not having a diskette drive; or burning drive; or hard drive. To me those "features" represent advances, and I can accommodate them as readily as I accommodate not writing "if / then", or punched tape / cards. However due diligence on the way into the store never gave me an inkling that I might wonder about the thousands of people scratching their heads pondering what to do with expensive state-of-the-art devices that do not cooperate with the world as it exists. A network device that will not reliably connect with a network could be seen as a deeply flawed device. The substance I brought to that table was not. Good green money, and glassy-eyed belief, were rewarded with "You asked for that, but you're getting this. Get over it." I didn't, and I wont. And as of this writing it would appear that new rubes are still lining up bleating "Hey, what's the matter with this thing?" Troll? Perhaps. Stupid? Not hardly.

i can confirm that verify/repair Keychain with Keychain Access Utility solved all wi-fi problems on

3 MBA here in my office.

During verify task i noticed two permission errors in com.apple.security.plist, so i launched repair

and permission errors gone.

thanks to crbtaylor who find for first a solution (for my problems) on this thread...

Okay here's my fix -- I'd done all the earlier fixes for my Macbook Pro and I've had no improvement in Wi-Fi connection; my Wi-Fi is (was) intermittent and when connected, very slow -- losing packets like crazy. Here is my solution for you all to try to turn your slow machines into fast internet rippers! To start, I am not a computer expert. I just finally luckily found the answer after a hundred of wasted hours of research and tech support from Charter cable and Apple. My solution is the wireless router itself. I had done all the prior mentioned adjustments and found no relief. What did it for me is going into my Charter Netgear router and unactivating the IP FLOOD DETECTION. To quote someone much more knowledgable then me, "IP Flood Detection is a type of Denial of Service attack whereby the victim or system is flooded with information, using up all available bandwith thereby preventing legitimate users from access." I had to log onto my WI-Fi router and then use navigate to a special page to find this feature.

If this does fix your problem, feel free to send me a new iPad as a token of your thankfulness.

Differently of the first post of this thread, I have problems with wi-fi "n".

I just bought a Time Capsule (2T) yesterday and a Mac Book Air last week (11.6", 128 SSD, 4GB RAM, OS X Lion 10.7.2). I also have an old Mac Book White (2009, OS X Snow Leopard).

I bought Time Capsule to change my old router. Time Capsule works fine with "n" wi-fi.

When I'm near Time Capsule (TC), both computers shows the same results (very high speeds).

However, when I leave the room where TC is, in certain points of the house, the old Mac Book White shows velocities ten times faster than the new Mac Book Air.

In both machines, bluetooth is always off.

I'm really very disappointed with Apple.

Count me in as a 2011 13" Air user who is having wifi issues. I can't connect to my 5ghz network all the time and when it does, it's very unreliable. The MacBook Air has no problems connecting to my 2.4ghz network but it's also strangely slow at times with unresponsive Internet. The Internet will just take a dive for a few seconds and then resume. I have ZERO issues on my 17" MacBook Pro with this wifi network so Apple has no excuse for this.

Someone with some time on their hands should gather all this info and put it together in a manner where we can make some proper noise. I'm not sure these large threads always make their way to Apple, especially since WiFi is finnicky in general but the evidence is clear that there is issues with the hardware/software related to MacBook Air. It's very clear in this thread as there are many cases where I see similar issues.

I really don't want to go back to my 17" as daily use but if something doesn't clear up in the next 15 days I'm probably going to have to return this.

EDIT: I have issues even with bluetooth turned off.

I am having the reconnect issues with both my 13" and 11" MacBook Air i5. I was able to narrow this down to some kind of a conflict with the bluetooth; if I turn off my bluetooth, the poblem goes away...

Here's an update...

My girlfriend also has a MacBook Air... her bluetooth is turned on and was near me and noticed that my Internet was much slower. I asked her to turn it off and my slow Internet issues disappeared and has been going strong for awhile now. If you guys are using this in cafes or public spots with lots of devices you might be experience bluetooth interference. At first I was thinking it was only related to my bluetooth internally but it looks like it's affected by external sources as well.

Please try this, turn off all bluetooth devices around you and see if your experience is better. I still cannot connect to my 5ghz band wifi.

I'm not saying this is a solution, just an update to my experience with bluetooth and it's affect on the MBA wifi.

I think Apple is going to have to own up and do some type of mass recall/replacement on these devices at some point.

128,000 views+ and counting on this thread, and not a single legitimate solution offered by Apple directly, not even acknowledging the issue.

At least Steve Jobs acknowledged the iPhone 4 owners to go screw themselves ("just dont hold the iPhone like that") before admitting to antennagate, and then offering cases in response.

This new Apple policy of silent treatment is just bad. I can see it now - Tim Cook: "Let's just ignore them...and hope they buy the next MacBook Air with the retina display instead."
