Airport says no airport chip installed

When I turn on my macbook pro, the airport function says "no airport chip installed." And nothing I've tried has worked. The wireless functions worked fine yesterday. I don't know what happened. Any suggestions?

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.

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?

Thanks for the flag J.K. - they contaced me and solved my problem. On this account (which I created just to ask this question), I log in with my email rather than my user name (mtalldud). On the account that I was having trouble with, they told me to use my user ID instead of my email to log in and it worked. This is a bit confusing and seems a bit inconsistent but at least I don't need this temporary account any more to get into this community and find answers!

Why does the airport say there is no airport card installed?

I have had my MacBook Pro for 4 years now and have never had an issue. I turned my laptop on the other day and all of a sudden I can no longer connect to wifi and the airport button just says there is no airport card installed?

The usual reason is that the Airport card has failed and will need to be replaced.

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.

It's still working right?

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

Why does computer say "No airport called installed"?

I have been using computer, with airport for wireless for years. Today I walked from one room to the next, opened computer, and it said "No airport card installed". Can I fix this myself. I have installed hard drive and ram myself but don't know much about airpord card.

It is possible that the AirPort card in your MacBook Pro has either failed or is not initializing properly at startup. I would suggest that you first rule out any hardware issues by running the Apple Hardware Test. Please post back the results of the test.

Computer froze; after reboot: "No AirPort card installed."

I was online checking email, doing nothing out of the ordinary, when all of a sudden my computer froze. There was no spinning wheel; the computer was completely unresponsive. I manually powered it off, and when I turned it back on and found that I could not connect to the internet. I clicked the AirPort icon and the dropdown said "No AirPort card installed."
I reset the PRAM. I did an SMC reset. I reformatted the hard drive and reinstalled OS X. I did both the standard and extended Apple Hardware Tests and there was "No trouble found."
In System Profiler, under Network > AirPort, the various Software Versions are listed. However, AirPort is not listed under Network > Active Services. In System Preferences > Network, AirPort is "Off" and when I attempt to turn it on, nothing happens. If I delete the AiPort connection and try to add a new one, "AirPort" does not appear in the interface dropdown menu. I tried turning AirPort on via Terminal using the command "sudo ifconfig en1 up" and received the message "ifconfig: interface en1 does not exist".
At this point it seems as though the AirPort card has crapped out, but if it did indeed go bad, why does it not show up in Apple Hardware Test? Does anyone have any suggestions for me?

As I understand it, the SMC and PRAM are actual chips on the logic board, and the resets restore them to their original factory values. That's about all I know to say about them since I'm not an IT person and have very little troubleshooting experience myself.
I'm not familiar with the term NIC. Is this the same as the airport card?
http://www.powerbookmedic.com/13-MacBook-Airport-Card-p-17152.html
If so, it should be easy to locate on the logic board as it's pretty large. I don't know if the same card is used in both of your 13" Macs or not--You would need to research that for yourself. However, it seems like in many cases, replacing the card didn't seem to work, although you could always inspect it to be sure the antenna is well seated. I'm not familiar with the 13" card, but the card in my 17" MBP actually has 2 antennas.
Both PowerBook Medic and ifixit have step by step guides for disassembling Macs and replacing parts. You may be able to find the information you want there.
Just finished looking through the long thread, and it looks like every possible solution that I could think of has been tried.
As for testing the hardware, many people have recommended Tech Tool Pro:
http://www.micromat.com/
You also should have the Apple Hardware test on one of your original system discs, and if you had Applecare, a Tech Tool Deluxe disc with a hardware test. I'm not sure, but it may be that if you purchased Applecare and got Tech Tool Deluxe, you may be able to buy Tech Tool Pro at a discount.
Apple Stores also have a hardware test they can run from their store feed if you have access to one.
If you do decide to resort to a USB card, here's one that works pretty well:

"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...

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.

System extension cannot be used, now no AirPort Card Installed?!?!?!?!

I have had my MBP for some time now and the other day it went into a kernel panic and after having to go through all the processes to recover it including restoring from the time capsule so that it doesn't take over 10 mins to start up an error message came up saying;
"*System extension cannot be used*"
"the system extension '/System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AppleAirPortBrc m4311.kext' was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update"
Now i cant use my airport card at all, it says that there is no airport card installed and I have spent hours on the phone to apple, done the option + command + r + p thing and had to restore my whole system off my TC with the backup disks and all.
Plz plz plz plz help, i just want it back the way it was, this is so annoying

I had the same problem. It happened to me after I updated to 10.5.6. I didn't notice the problem until I rebooted a few days later. I reinstalled the system from disk and then realized that even though it took almost an hour it didn't really install anything. So I deleted the whole /System/Library/Extensions/IO80211Family.kext and reinstalled the system again. This time it worked

"No airport card installed" error message onMacBook Air.

Early today, my Macbook Air froze and I had to restart it by holding down the start key. Since the, I've been getting a "no airport card installed error messge". I've tried resetting the PRAM but it did not fix the problem. I've also tried running the hardware check through a powerdrive but I get a message saying hardware check cannot be run on this machine. Any suggestions about what to try next?

Yes, you should remove and reseat the Airport Extreme card. It may just have been jostled in its slot and not be making good contact now.
