I purchased a new MacBook Air with OSX 10.7.1 at the end of July. When I unboxed it at home I couldn't get a wifi connection. Once every three days it works, for about an hour. Then I lose the connection again. Sometimes it shows full strength on the wifi icon but nothing happens, sometimes I get contiuous popups complaining about a connection timeout, but mostly I have the wifi icon with an "!" in the middle of it.
It's not on all networks. In a coffe shop I got wifi, as well as at the house of my brother. Still. It's not just at my home the problem occurs and it's quite annoying!
My wifi is a "B-Box" installed by my IPS "Belgacom", it's a typical setup used by half the people in Belgium. My Asus and Dell notebooks, as well as my iPhone work just fine on the wifi. I never had any problems before.
For the past two month I've read all the forums and tried many proposed solutions like turning off bluetooth, downgrading the wifi driver to 10.6.8, changing the order in Network Preferences > Set Service Order so the wifi is at the top of the list, flashing the PRAM, ... Nothing helps.
Tonight I'll try the here proposed solution of setting a fixed IP on the router, but I don't like that idea too much. It doesn't really solve the issue itself, it's workaround.
I've gone to the Apple store and they had no idea what's wrong with my MacBook Air. I've gone to the FNAC store where I bought it and they don't know either. They proposed to send the machine to Apple Repair. But with it not working right out of the box, and only on certain networks, I don't see what they'll do that I haven't tried before. Aple Repair says it'll take 2-4 weeks and I can't miss my computer that long.
There's similar thread on MacBook Pro here: https://discussions.apple.com/message/16345483
Anybody knows more about this by now?
Updating to 10.7.2 fixed this issue on this 2011 11" MacBook Air.
Previously on "G" networks I would get the dreaded "!" wifi symbol even though there was full wifi strength. Curiously, my 13" MacBook Air was able to connect without any problem, even on 10.7.0 and 10.7.1. The wifi on the 11" is working well now after updating to 10.7.2.
the 10.7.2 may have fixed something for you on a macbook air 11", but not for everyone.
there are still conflicts between the bluetooth driver and the WiFi driver for tons of people, including myself- a veteran mac and linux sysadmin with a macbook air 11".
see the postings over at this thread:
Problems still in full effect when I use the machine in clamshell state, connected to an external monitor and with Bluetooth peripherals. I haven't even bothered using my home office in weeks due to the annoyance and frustration. Guess it was too good to be true that it might be working now.
Lion 10.7.2 addresses some of the wifi issues, as explained at http://reviews.cnet.com/8301-13727_7-20120069-263/os-x-10.7.2-what-it-fixed-and- what-it-didnt/?tag=mncol;3n
After the upgrade my connectivity has been a lot better! Initially the upgrade caused the auto-reconnect to fail, but this I managed to fix by following recommondations 2 and 3 from this article http://reviews.cnet.com/8301-13727_7-20095988-263/fix-wi-fi-autoconnect-problems -in-lion/?tag=mncol;txt
Now it works most of the time, with accasionally much packet loss and reconnections. Practically speaking, web browsing works well enough, but a large download will be ever so slow and when watching something on youtube playback will halt every 5 minutes or so and then I have to reload the page.
10.7.2 has given me hope, Apple does seem to be working on these things. I'll continue trying out what others post here. Thanks for the help so far!
The problem at my house on a single network has definitely improved. I get faster and more consistent reconnects on wake. I also am getting better average speeds. I do need to travel a bit more with the laptop sleeping, waking and switching networks for a complete opinion. The problem certainly is not longer unbearable for me. Long overdue and the Lion/MBA should have never been released with this pretty major flaw, however, begrudgingly, thanks Appple.
here the same. Macbook Air 3,2 Nov 2011, Lion 10.7.2 tried all the workaround read on the net and forum, but I'm still having drop issue. Problem is that at home I can deal with router settings and try to get things working, but at Office isn't possible. I don't think it is a router issue, but a driver problem. We all need URGENTLY a fix for that.
Same problem here. No wifi reconnect after sleep unless Bluetooth is turned off. Latest Macbook Air with Lion preinstalled and all the latest updates (Lion 10.7.2). Had the problem from the beginning and none of the software updates fixed it.
I tried it many different wifi environments incliding an Apple Store, its all the same, so I can exclude any router issues.
The only bluetooth device I use is an Apple Magic Mouse, the funny thing is that the wifi actully reconnects when the mouse is turned on (albeit it takes a little longer then with Bluetooth completely off), but when I turn off the mouse the Air fails to connect to wifi after sleep.
Went to an Apple store and they did some things like clear the PRAM and delete plist files, which fixed the problem temporarely, but it came back I suppose as soon as I reconnected the Magic Mouse.
The irony, in bootcamp the wifi reconnects like a charm.
This is pretty clearly a problem with Lion. I wonder if anyone has gone back to 10.6.x. If I had unlimited time to labor unpaid doing that kind of tech work, perhaps I'd try it, but since I bought my new Air to _facilitate_, and not stall, my workflow, that sort of job is really out of the question. I should add that I've already spent countless hours on this problem - tracking down its nature, researching it, documenting it, trying various fixes (none of which have worked long-term), posting here and elsewhere, etc., so I'm already resentful about spending any more time with it.
I find my worse scenario with the machine I have is when it's in clamshell mode, plugged in via HDMI to my external monitor and using Apple's wireless keyboard and trackpad via Bluetooth. It usually is rendered unusuable in this state for anything requiring network connectivity.
I encourage anyone who posts on this thread to also vociferously Tweet using the hashtag:
That's MacBook Air Wifi FAIL.
It's still my hope that some high-profile tech bloggers or other sites (e.g., MacRumors; ArsTechnica) will pick up this story.
Apple never replies on these forums. In fact, rarely do they ever read these forums. They are probably aware of this problem, but we'll have to wait until they get around to releasing a fix.
The only way to get Apple to move faster is to move the spot light on them. If anyone knows someone in the news media?
Unles that happes we wait.
By the way, if it does reach the media. you can expect this thread to be deleted. Standard behavior for Apple. I love Apple products but HATE the company's PR.
