WiFi Issues With MacBook Air

I'm glad you're having better luck today, but I have to honestly tell you that it's not likely to stay that way. There is some fundamental architectural problem with this hardware, and routers are not the issue. I'm not sure what "a loop in the system" is or means; that's not really a technical term or description I've ever heard anyone use, but you can safely return that Airport Express, because it's most likely not the problem whatsoever.

The bad news is that what seems fixed right now is unlikely to be.

Good luck.

Hi,

i solved the problem this way,

first reset PRAM (google for "reset PRAM lion" if you don't know how = restart and immediately push these buttons simultanously [option] [cmd] [P] [R] )

then

in network prefs, uncheck "ask for confirmation when connecting to other networks"

(or something of that kind, i don't use the english version)

this solved my problem

hope it will help you as well

give peace a chance

;-)

Hi,

i also have similiar problems with the Wi-Fi of my brand new MacBook Air (i7, 256GB SSD, 13inch). After deleting all known wifi networks and uncheck the options "show new wifi networks" (i don't know the expression at the moment) and re-connect to my Wi-Fi Network the problems are gone.

But Wi-Fi is extremly slow, i hope Apple will fix the Wi-Fi Issues in 10.7.2.

Been surfing a lot today (lazy sunday 🙂 ) and my wifi has dropped dozens of times. SO driving me nuts. Just trying to keep this thread alive. Been plugging in using the USB ethernet adapter... funny that works fine!

No luck here. Tried every fix I've read and even bought a new router. MBA 11 with Lion wireless not only chokes constantly but it also causes other Windows 7 laptops in the house to choke when trying to surf at the same time. 10.7.1 had no effect. Seems to work well on enterprise network at work though on corporate and guest wireless networks.

Hello!

I found out, that the WIFI-problem has something to do with the Bluetooth-function.

So I turned bluetooth off, and deleted following files in "Library" --> "Preferences":

com.apple.Bluetooth.plist

com.apple.Bluetooth.plist.lockfile

After a reboot all was fine.

But if I reinstalled my Magic-Mouse and Wireless-Keybord, it is all the same and the Wifi-problem still occures.

I hope that the new update to 10.7.2 solves this problem - I can't understand why Lion was released with this issues of main functions.

I encourage EVERYONE on this thread who is continuing to experience problems to take a parallel discussion to Twitter, using the hashtag #mbawififail - That's MacBook Air WiFi Fail.

It's only when third-party tech journalists and others take note that Apple will feel enough pressure to respond to this situation. Until then, this thread will continue to languish with no official acknowledgment, much less response, from Apple personnel.

I just did, althought I'm a tweet novice and not sure I did it correctly!

Also, anyone have a chance to test the new EFI update for the Airs? Wondering if it changes anything relating to Wifi.. My guess is that it doesn't but who knows!

So far so good with the latest software update. We were so frustrated with this MBA and its inability to stay connected to the internet via wifi.I just found this thread and at least I know we were not alone.

I'm cautiously optomistic that it may continue to stay connected.

Just to add voice to others who are also having intermittent Wi-Fi dropping on MBA mid-2011. I never had any of these issues in 10.7.0. However since updaying to 10.7.1, I get intermittent drops of the Wi-Fi, once every half an hour or so. Sometimes the Airport icon indicates it's connected, but when I try to use the Internet, I get connection errors. These drops tend to last around 1-2 minutes before reconnecting. I know it's not my router because I have a HTPC and iPhone 4 also connected on the same network, and network/browsing tasks work fine whilst the MBA is down.

I'm still having massive issues, even after installing the EFI update.

The problem occurs on wake or after a clean boot. The Wi-Fi drops tend to last anywhere between 1-5 minutes. Also, my MBA is connecting to the Internet through an Airport Express.

Hi,

whatever people may say here, resetting the PRAM works for my MBA mid 2011 (Lion 10.7.1), it worked for over a week, and when the wifi-speed dropped, restarting the MBA didn't help, switching off and on wifi didn't help, but RESTARTING and RESETTING the PRAM worked...

So have a try although some websites claim that nothing that could influence wifi-speed is saved in the PRAM

let's hug the world

;-)

After trying all the fixes that worked for others with no good results including trying 3 different wireless routers with different bands, channels, encryption etc., I finally a fix. A day after the EFI update which didn't help me, I had my broadband service upgraded from 10Mbit to 40Mbit. That came with a new cable modem with built-in wireless. My previous cable modem had built-in wireless and didn't help my issue. That was a Netgear. This is a Ubee (never heard of it before). I've had no problems since this was installed which I don't understand. Nothing was changed on the MBA to resolve this other than connecting to the new wireless network which is using WPA/WPA2 just like the other 3 I tried. Maybe there was some sort of synch or timing or latency issue with connecting to the 10Mbit cable modem connection?

Sorry, but I'm just jumping in at this late point in the thread. I have been having the same problem, dirkfromvlissegem, with a frequent dropping of wifi connection on my mid-2011 MBA 13" and your suggestion to try restarting and resetting the PRAM caught by eye. How does one reset the PRAM?

Resetting the PRAM is done by restarting and hitting command-option-P-R before gray screen comes up. Let the start up bell chime twice. (Anybody more computer savy please correct me if I'm wrong.) Resetting the PRAM did not help me. My problem seems to be a little different. My wireless bar remains full, but pages stop loading. I turn Airport off, then turn it back on. Network assistance pops up and takes me through the usuall steps. 99% of the time, this works, and every now and then, a box shows up that says that my network configuration has changed. (whatever that means) This is very annoying. The posts for this are all spread out over this and other forums going back to 2007. For all I know, there's a fix somewhere, but I just haven't found it or I'm not Mac savy enough to understand it. At what point do I just run an ethernet cable and be done with it? Are their any USB WiFI options?

PS, I had to restart my wifi twice while posting this and had I not copied before resetting, I would have had to start all over
