MacBook says no airport card install suddenly

My MacBook suddenly lost wifi connection and says that no airport card installed. How can I reinstall the card?

There are a couple of things you can try to get your AirPort card working again.
Reset the Parameter RAM - http://support.apple.com/kb/PH11243
Reset the System Management Controller - http://support.apple.com/kb/HT3964
If neither of those works, you probably have a dead AirPort.
Contact Apple using www.apple.com/support/contact if you are in a country that supports it or call the appropriate phone number on this page. Alternatively carry the MacBook in to an Apple retail store or service provider to ask for an estimate.
Best of luck.

Help! my airport says "No Airport card Installed"!!

My computer has been working fine and now i just turned on and my airport is gone!! it won't let me do anything wireless and when i click on the icon at the top it says "No Airport Card Installed"!!
it was working just fine an hour ago!! my computer is about a year old and full updated with snow leopard.
Could this be a virus? only thing i loaded today, beside torrent files, was the Flip4Mac upgrade.
Would appreciate it if anyone can help me!!
thanks,

It's not a virus. Try resetting your SMC (system management controller). Does System Profiler also show that the AirPort card is not installed?

Can't boot from install disk, and says no airport card installed, HELP!

I bought a new Macbook Pro a few months ago, which recently had to go in for repair to have the screen changed. It came back with the new screen fitted but they had done a terrible job at aligning the lid, so it went back again. Came back and all looked good, until i booted up and realized that where my wifi icon is at the top of the screen, it wasn't connected. When clicking it to bring down the drop down menu of available wifi spots, all it said was "No Airport Card Installed"....Thinking a repair of disk permissions might be worth trying, I tried to boot from my OSX install disk holding down C, however when holding down C all it does is go on a constant loop of restarting, not even reaching the Apple logo. If I don't hold down C then it simply boots to the desktop, so i'm unable to access disk utility correctly to run a repair.
Being pretty fedup with the whole situation, the laptop has now gone back for a 3rd time, as it never had these two issues before. I was just wondering if anyone had any idea what might have caused this? And how a status of no airport card installed and a drive that wont boot a disk normally can be related?
I'll be getting it back on Tuesday, but i just wanted to know what the heck they might have done to have screwed things up.
Thanks
Phil

Hi Phil,
I can't say for sure, but it sounds to me like they didn't reconnect the WiFi hardware when replacing the screen. To my knowledge, the Airport "hardware" (including the antenna) is located inside the screen hinge. When the screen was replaced (and the hinge not properly aligned) perhaps someone improperly connected the Airport hardware, or forgot to connect it entirely.
The reason the WiFi hardware is located in the hinge is because that is the only plastic area of the entire notebook. Radio signals do not travel well through aluminum, so some area of the computer has to be plastic to allow that signal to get through. The hinge is the only area where that's possible.
As for the reason why the machine wouldn't boot up from the disc, I have no idea. Here's hoping it does when it comes back. If I were you, I'd have a chat with Apple Customer Relations about the situation.

Macbook pro"No Airport Card Installed"

So my macbook pro has a grocery list of problems wrong with it, it constantly freezes and shuts down on me and it has a really hard time picking up wireless internet no matter where I am. Also part of the back of it is broken (from being in the car when I was in an accident) But the guys at the apple store say that is just more of a cosmetic issue and it shouldn't hurt how it works. But it has been getting worse every day and in this past week it has been shutting down and freezing more than ever, sometimes I have to even take the battery out in order to shut it down when it freezes. But yesterday when I opened it up it read "no airport card installed", so I got on the phone with a guy I know who knows everything there is to know about macs and he told me to go under system preferences and delete my airport then restart my computer to reset the PRAM and then add another airport under system preferences I did and that worked perfectly last night and restored everything back to normal. Then this morning it did the same thing so I reset the PRAM again and it worked(which I had to do mulitple times whenever I would open my laptop back up)but then this last time it didn't work. And I cant find the airport anywhere under system preferences/network. I've ran disk utility and repaired disk permissions and nothing has worked. I'm out of town right now but I plan on taking it into the apple store as soon as I get back.

I should clarify ... I had this same problem on the old drive but only after restarting from boot camp. But an old platter hard drive is simply too slow to bother with boot camp for my needs, so I just went back to OS X only.
It hasn't been an issue since last Christmas when I first noticed it. Since then, I've had every single part of this Macbook Pro replaced except for the battery, battery cover, and back panel plate. Some components were replaced multiple times. But it's not been a problem because I haven't been using boot camp.
I really don't see how it could be a hardware issue when it only happens during restarts, not during cold boots ... and only happens going from Windows to OS X, not the other way. Could be something in a hardware check from cold boot that doesn't happen on a soft reset.
Other people seem to be having issues with their airport cards not being recognized for a variety of reasons. I suspect it's something an update will cure. Or it'll just be like a variety of other minor bugs which Apple hasn't bothered to fix yet (like the keyboard backlight not switching off under bootcamp, etc).
Thanks for testing it out on your systems. Was just curious if anyone else had seen the problem.

I suspect the OnyX routine is going to show promise if a corrupt cache file is responsible.

No Airport card installed error

Hi evrybody
I've just bought a Macbook Aluminum 13inch. Everything's ok, but suddenly, when I click to wireless icon on the menu, it say: "No Airport card installed".
I did the following:
+ In System profiler --> Airport card: No information found
+ Hardware test: No problem
+ Update software
+ Reinstall Mac OS
+ Remove battery, hold Power button for 10s
+ Press Option + command + P + R
But still "No Airport card installed".
It happened when I use 10.5.5. I update to 10.5.6, and then 10.5.7, there's no use.
I'm in Vietnam, there's no trustable Apple care here. Please help me.
Thank you much.

Thank you. I brought my Mac to the provider. They said they gave a new one for my Mac. It run now. But I think that they only update firmware because my card serial is still the same. Any way, it run now. Thank you for your help.
I don't believe that the new (unibody) MacBooks have any separate AirPort card that can be individually replaced. The photos I've seen of disassembly don't seem to show any separate wireless card. It's just a Broadcom BCM4322 which is more than likely permanently soldered to the main board.

"No airport card installed" only in swedish mode?

Hi all, got this problem with my Macbook pro!
Recently when I was reconfiguring my wifi-network (assigning my time capsule as main router and the modem I got from my ISP as a "bridge"), I noticed that my airport card was acting strange.
The problem is that it says "No airport card installed", but I still got internet connection and can surf/download stuff without a problem. Also, when I go into "System preferences/Network" I can see my airport connection and turn it on/off. Although when I click "Advanced" nothing happens.
I've tried several things but none seems to work, and I'm not sure its an hardware issue. Anyway, this is what I've tried:
1. Rebooting (several times) = Didn't work
2. Resetting PRAM and NVRAM = Didn't work
3. SMC-reset = Didn't work
4. Rebooting into Windows XP via bootcamp = Airport card detected and working just fine
5. Restoring older save via time capsule = Didn't work
6. Format and reinstall Snow leopard and restore older save via time capsule = Didn't work
7. Format and reinstall Snow leopard (again) = Didn't work...-ish?
Now, here's the strange bit. As I log in to a new account with english as main language I notice that the wifi-icon on the top dashboard now is filled (it was greyed out and only said "No airport card installed [in swedish ofc]) and I can now click it, change network and all that stuff. Although, when I go to "System preferences/Language & text" and change my preferred language to swedish and log out & in, the same problem occurs (greyed out wifi-logo, no airport card installed etc.)
So, I'm totally confused. Halp?

Have you done a PRAM reset, CMD+Option+p+r...
http://support.apple.com/kb/HT1379
In fact, do 3 in a row, takes a bit of time.
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If that doesn't help Reinstall the OS.
If that doesn't do it, the card has likely died.

"No Airport card installed" after 10.5.8 update

Just upgraded the latest Leopard update 10.5.8 and, after restart, the Airport icon in my menu bar says "No Airport card installed".
I've been into System Prefs and tried to switch it on, but nothing. I've even been into the system profiler and, when I look under Network > Airport card it says no information found.
I'm on a two-week-old 13" MacBook Pro, which has been working fine with its Time Capsule since it was bought.
Cheers in advance.

HI,
Try the 10.5.8 combo update available here.
http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
As with any installation, repair disk permissions.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.

New MacBook cant see Airport Card

Just bought a new MacBook "refurb" from the Apple store. It was running fine, and accessing wireless networks, but just last night, it stopped seeing the Airport Card. When you click on "turn airport on" in Network Preferences, or you click on the airport icon in the Menu bar, it says "No airport card installed". I have tried removing the airport preferences file and rebooting. I have tried repairing preferences and resetting the PRAM, just in case it is software related. Anyone had this problem, and what was the fix. I am afraid I'm going to have to send it back to Apple for repair.

Although, you can certainly try "troubleshooting" the AirPort Extreme built in your MacBook, since you just got it from Apple, I would strongly suggest that they take a look and make the necessary repairs.

"no airport card installed" on 17'PowerBook G4 after installing 10.5.1

My Airport card suddenly went away. System profile says 'no information" and finder bar says : no airport card installed" I have tried removing the .kext file in question (AppleAirport.kext) to no avail. Tried zapping the pram, safe mode etc. Apple techs no help. Anybody know the fix? Thanks in advance for the help.
PS, I must mention that I have had numerous other issues with 10.5 and 10.5.1 - I dont think it likes PowerPC's!
cheers!

Just got the same problem on my 17 inch powerbook again, Previously fixed by repairing permissions and repairing disk with the disk utility. Not this time. Your previous note is several month old- did you resolve the problem?

Problem with Airport. NO AIRPORT CARD INSTALLED

Hi, im using Mac OS X ver 10.6.8 my problem is with the airport. it says no AIRPORT CARD INSTALLED. This was just suddenly, and i cant find the solution. if somebody could help me on this matter. thank youP

You could try resetting the SMC and the PRAM. But I suspect the Airport card in your Mac has gone Bye Bye, died. The only way to fix that, If the 2 resets I posted above don't help, is to replace the Airport card.

"No Airport card installed" - but works!?

I have a strange issue. Suddenly my airport icon in the menu bar turned grey and if I click on it it says "No Airport card installed". But, Airport is working fine and I can "see" the Airport in the system preferences/network. The only other issue I have noticed is that hitting the "advanced" button will not pull up the "advanced" pane (in system preferences/network/airport).
I did a repair disk and permissions prior to noticing this problem.
I have tried to several tips on the forum including re-starting, ctrlalt+pr and then finally re-installing 10.6(.1). No luck.
I have seen many issues with Airport and 10.6 on the forum but none really similar to this.
I would be grateful for any suggestions on resolving this issue.

+I did a repair disk and permissions prior to noticing this problem.+
Then that would be exactly the cause of your problem.
If you have Snow Leopard installed as your profile indicates, you better have been booting from the Snow Leopard Install Disc and using the version of Disk Utility located on it to do your Repair Disk.
Afterwards, you should have quit Disk Utility and restarted from your internal hard drive - then ejected the Snow Leopard disc, opened your installed version of Disk Utility and used it to perform Repair Disk Permissions.

Latest Apple Software Update causes 'No Airport card installed' error

Hi,
I accepted the Software Update released 05Apr08 and rebooted. Following the reboot my MacBook Air now says 'no airport card installed' and I can't get the MacBook to 're-recognize' the card.
I have used the airport card to access many different wireless networks prior to this update with no issues.
All advice accepted gratefully.
Thanks.

I'm having the same problem with a brand new Macbook Air I picked up on Tuesday. When I got it home I updated all software to latest, and didn't have any issues...
Sometime on Thursday, however, after waking from sleep the airport card reported it is off, and no amount of attempting to turn it on again would successfully do so. After a restart, the computer reported no Airport card is installed at all. I had to shut down the computer and turn it back on before the airport card was recognized (and work) again. This is now the case every time the computer is put to sleep. Occasionally after I do this, the network will be incredibly slow, something like dialup speeds.
First I tried resetting the PMU (http://docs.info.apple.com/article.html?artnum=14449), but that didn't work. Then I reset the PRAM and NVRAM (http://docs.info.apple.com/article.html?artnum=2238), which worked for only about a day. Now here I am again with the same issue, and an appointment for the genius bar at 5pm tonight.
