"No AirPort card installed" error persists on MBP even after reboot

I am getting a "No AirPort card installed" problem on a brand new macbook pro 13 running OS X 10.6.1. First, I experienced applications freezing randomly, until my MBP froze completely on me and had to reset it. This issue became recurrent, and now there is this network card problem. Rebooting does nothing to get AirPort to work again. I will truly appreciate any insights on how to address the latter issue. I am hoping it is simply a software problem.

Brand new? Take it to an Apple store or AASP. Newer MBP owners post here: MacBook Pro (Late 2008 and 2009) http://discussions.apple.com/category.jspa?categoryID=251

"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.

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" error message

Please help--
I have a PowerBook G4 12", recently refurbished, running Mac OX X 10.5.8, 1.33 GHz, PowerPC G3, 1.25 GB memory.
It works great. But this evening, my daughter dropped it onto a hardwood floor. At first, I thought everything was fine.
But now, I get a message, "No AirPort Card Installed" message when I try to turn AirPort on.
I'm typing on it now, so I'm able to go online using an ethernet cable, but I need AirPort connectivity.
I've been religious about backing up on Time Capsule. Would it help to go into my Time Capsule to bring back an old AirPort setting? Should I remove, then reinstall the old AirPort card? Or will I have to buy a new AirPort card? And do they still sell those for Macs this old?
Any info you have would be helpful, thanks.

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.

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!

Brand new MBP 13 inch, "NO AirPort card installed" message

Hello!
I just bought a new MBP 13 inch and cannot connect to my home wireless network. On the top bar and when I put the mouse cursor on the AirPort icon it says "No AirPort card installed". Shouldn't the card be pre-installed by Apple though? Currently I'm using an ethernet cable to connect to the internet which works fine.
Thanks very much in advance!

Open Utilities/System Profiler and in the left column click on Airport (in the Network section), does it show any details for the hardware or is it blank ?
Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys.
If still no joy then you need to take it back to Apple for them to check it out.

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" message

I've been using my new 13" MBP for five weeks and the AirPort card has worked fine. Today, however after waking it from sleep the connection was gone and the AirPort icon was blank. I clicked on the menubar icon to "Turn AirPort on" but nothing happened.
After a quick permissions repair and a restart, the blank menubar icon reads "No AirPort card installed."
I have tried to reset the PRAM.
I have tried using my TechTool Pro eDrive to seek problems. None found. (The same AirPort card message was in eDrive mode as well)
AirPort software specs are available in System Profiler:
Software Versions:
Menu Extra: 6.2.2 (622.2)
configd plug-in: 6.2.5 (625.6)
System Profiler: 6.0.1 (601.1)
Network Preference: 6.2.2 (622.2)
AirPort Utility: 5.5.2 (552.11)
IO80211 Family: 3.2 (320.1)
Airport configuration is still available in my Network prefs: "Status: OFF" - although the AirPort ID is zeroed out.
Console report:
4/14/11 9:09:04 PM Apple80211 framework[372] airportd MIG failed (PowerEnable Event) = 5 (Input/output error) (port = 29211)
I suspect this is a hardware error and beyond the means of a software fix, unless somebody knows otherwise.

So, as my laptop is still under warranty, I spoke to customer support, who were very helpful.
The problem was that there was not enough power getting to my AirPort card. The solution was to shut down and restart by pressing the power button and then Shift-Control-Option. It started up, and the AirPort card was up and running as normal.
We'll see if this is a recurring problem with the MBP, but, so far, so good.

Wi-Fi gone: "No Airport Card Installed."

Last night I watched Netflix just fine, put my laptop to bed and this morning, no wif-fi connection!!. Blank airport icon reading "No Airport Card Installed."
Recently installed new battery, not that that probably matters. Do you think my Airport Card died overnight? I have tried restarting twice and nothing. Other devices can connect to the wi-fi just fine. Any suggestions? Looks like this, below.... thank you tech-heads for any help you can give me. Staying tethered to the modem is a drag... especially since I just forked over $130 for a new battery! I have a MBp-17 with OS 10.5.8, Mahalo from Kona Hawaii.

Unfortunately this probably means that your MacBook's AirPort card has died. Last desperate effort at reviving it, try resetting the PRAM on the MacBook and if that does not change anything reset the System Management Controller.
If none of those work, carry it in for service or call Apple at the appropriate phone number on this page to have them set up service.
Best of luck.

Getting message "no airport card installed"

I can't connect to my wi-fi network and internet. I'm getting the message "no airport card installed" on my 2010 13" MBP. There is a card installed. If the card has come unseated can I reseat it myself or do I have to take it to the apple store
Thanks

I'm having a similar issue. My airport card was working fine and then, hours later - it does not recognize it on my new MacBook pro. Not sure what is up here ...anyone from Apple able to solve this one?

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" - what's gone wrong?

Without warning airport has stopped working on my late-2010 MBP. When I try to pull down the menu it just says "No AirPort card installed".
Can anyone suggest some possible ideas for fixing this, without a trip to the Apple store and losing the computer for a while?
Tom

Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys.

'no airport card installed' when I cllick on the Airport Icon - any software fixes?

'no airport card installed' when I cllick on the Airport Icon - any software fixes?

I would start by running the Apple Hardware Test directly from the Installation CD that came with your MBP.

Please post back your results.

"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.
