Airport card no longer found on Macbook

My airport card is no longer being found by my macbook. I haven't done anything different?

i'm having the same problem. was using my macbook (online, no less!) 30 minutes ago, put it to sleep, and then when i opened it up 5 minutes ago it could not find my wireless network. it gave me the message that "no airport card is installed" on my computer.
tried restarting a couple times but nothing changes...also, i can't try to tweak settings in the Internet Connect panel, since the airport option does not come up.
do i have to reinstall the OS, or is this something that should be "naturally" remedied after some more restarts?

Airport Card no longer recognized by PowerBook

I always take my PowerBook G4 to class with me for the purpose of taking notes during class. I was connected to the internet there, over the wireless network (on campus) with no problem.
When I got back home, my PowerBook wasn't seeing the wireless network (at home, seperate from the wireless network on campus), but I knew it was working because my iMac is connected to it just fine, along with two other computers in my house. I tried restarting a couple of times, and actually typing the name of the network into the Airport drop-down menu. This all did nothing, as did repairing the disk permissions.
I find it very unlikely that the card is not seated correctly, because first of all, when I brought the PowerBook back from campus (when it was working properly) it was tranported in my TUMI bag, which has a dedicated padded holder for PowerBooks, and then immediately took it out and sat it on my desk next to my iMac only to find the PowerBook no longer seeing the wireless signal.
And at this point, I could still turn Airport on and off, and I restarted the computer a couple of times to see if it would pick up the signal, all the while Airport was still recognized by the system (I could still turn it off and on from the drop-down menu, but no wireless networks were present).
So, I popped in my OS X DVD to boot from it to use the Repair Disk feature. It came up with an error that said something to the tune of "incorrect number of threads." It repaired the disk without any probems, or so I thought (and so it thought).
Now, the computer wouldl not function because it runs into a kernal panic, forcing me to hard shut-down the computer. It happened everytime, sometimes during startup, sometimes not until I got into OS X, but always soon after the OS starts.
I then booted the computer as a "Safe boot" and this seemed to stop the kernal panics, and I shut down the computer and started it again with no panics. There was no longer any recognition of the Airport card, either. Not even through the Airport Setup Assistant. It keeps telling me there is no card installed.
I have tried two seperate cards, as I thought maybe the one went bad, but nothing came of this. I tried zapping the PRAM, booting into Open Firmware to reset to defaults, all leading to nothing. I even went so far as to completely erase the drive and do a clean install of OS X, which now drops my system down to 10.4. NOTHING.
Please, anyone willing to help that would be great, even if you would like to contact me through iChat and we can discuss this over iSight to get to the root of the problem. Screen name is CoreyAtMiamiU.
Sorry about the long post and thanks for taking the time to read it.

This is a user to user discussion area. So it is unpredictable as to when someone with a suggestion will respond to your post. An hour in the middle of a work day isn't a long time.
Since the card is recognized, there isn't anything wrong with that side of the card. If the card isn't receiving a signal, either the RF side of the card has failed, the antenna wire isn't connected properly, or the antenna in the PowerBook has failed.

Broken airport card and hard drive on MacBook Pro and can't go to recovery with LAN.

Hi.
My MacBook Pro 13" (early-2011)'s hard drive has broken, and I bought a Kingston 120GB SSDNow instead.
Earlier, the airport card and cable has been broken too.
Are there other ways I can use LAN to recover my mac? It wants me to use wifi, but the airport card is broken...
If so, why does it only want to use Wifi instead of LAN?
LAN is like the extra parachute just in case, or the extra octopus regulator in scuba diving.

Is your model on the list? Did you ever upgrade its firmware? If not, then all you can do is start by booting from your Snow Leopard DVD and installing Snow Leopard on your SSD. Be sure to first partition and format the SSD for use with OS X. Once you install Snow Leopard you can download and install the firmware update for future needs.

Airport Card Not Installed Error on Macbook Pro 13

I've a Macbook Pro 13 less than 1year old. 3 days ago, I attempted to update my iPod Touch 3G from 3.1.2 to 4.2.1. While in the process, my iPod froze and I forced quitted iTunes.
On the next boot, Airport was off. And no matter what I did, it didn't turn on. I fixed this with a reinstall of the OS. Yesterday night, I turned off Airport to save power. Today morning onwards, I see the warning "Airport Card not Installed".
What could be the problem?

No idea, but here is a thread on this very subject and many suggestions which have worked for some people:

Good luck!

Airport card no longer installed

My mac thinks it does not have airport card installed. This started all at once and has worked once since it started. What's up? iMac 2.66 10.5.8

Maybe the AirPort card has a loose connection. You will need an authorized tech to open the iMac and check that out. Especially if it is still under warranty, which if it is, the warranty should cover the repair.

Airport Card no longer has acceptable range

Ever since the early days of OS 10.4, my airport card range became incapable of connecting more than about 6 feet whereas previously it was able to make a reliable connection 40 feet away through several interior walls. My router is a D-Link DI-624. The problem also exists with another router at a different location, thus I have concluded that it is my wireless card that is the problem and not the router.
Does this sound like a hardware problem or a software problem?
Is there a diagnostic procedure that I could use to determine the cause of the problem and how to fix it?
G4 1.25 PowerBook running OS 10.5.5,
Wireless Card Type: AirPort Extreme (0x14E4, 0x4E),
Firmware Version: Broadcom BCM43xx 1.0 (4.170.25.8)

The only real way to test is to swap out the card with a known good one. If everything is fine with the known good card then you know that the original card isn't working well.
I would speculate that it is more likely to be an antenna problem rather than a card problem. Either the antenna connection to the card has come loose or the antenna wire through the hinges has become damaged.

After Service, Airport card stops working randomly on macbook pro 17" early 2009

Hi,
So after the last time my computer was serviced, the airport card stops working randomly on moving the screen.
Upons restarting the computer, it sometimes says wi-fi hardware not installed. Then, if I move my machine around,
lift it up, turn it around, place it back on the table and restart it, it works again. I don't understand this.
And all this started happening the moment my warranty ran out. Extremely frustrating!!

It may be possible that one of the following may be the issue:
The internal AirPort Extreme card is not seated properly.
The internal Wi-Fi antenna connector is not seated properly in the AirPort Extreme card.
The internal AirPort Extreme card's connector is faulty or damaged.
The internal AirPort Extreme card is faulty.
To get an idea on how the Extreme card is installed, please check out the following iFixit article.

Airport card no longer detected

My Powermac G5 (dual 2.0 ghz, summer of 2005) has been running on my wireless network without a hitch until recently when it randomly stopped recognizing my Airport Extreme card after I restarted it following a software update. The card's installed correctly, but the computer just completely fails to recognize it. I'm really mystified, if anyone has any ideas it would be greatly appreciated. Thanks!

drewbwhite, I'll offer three suggestions.
1. Check the T shaped airport antenna on the back of your G5.
2. Reseat the card.
3. Do a PMU and nvram reset. Instructions here:

My MacBook Airport card has never appeared.

I have a new MacBook. At no time has the airport card made its presence felt. In System Profiler, it says re Airport Card 'No information found'. On Network Port Configurations, Airport is grayed out so is unresponsive.
The MacBook is located adjacent to an active 802.11 Netgear router. An adjacent G5 desktop machine receives strong wireless signals from the same router. The MacBook is able to log onto the Web via a built-in ethernet link to the same router.
According to Apple, Airport is standard on this model, hence my confusion. What advice can you give me? Is there some straightforward set-up procedure that I can follow, to avoid having to return the MacBok to the supplier 130 miles away?
Jonks.

If System Profiler is not showing the Card I fear it may have been jarred lose or just not connected during assembly. It's not like earlier ibooks etc. where you can get to it easily either. Sorry - I think you may have to bring it in.

AirPort Card & MacBook Pro

Hi,
I'm interested in buy a MacBook Pro at your online store.
But I'm not sure if the Airport Card is included in the MacBook Pro.
So do I need to ADD the airport card while i'm customizing my MacBookPro at your online store?

Airport cards are included with all Apple's current portables

I have airport express but it is not recognised by either my macbook pro or my ipod on my wireless network. It does not show in airport utility. Might I not have an airport card?

I have airport express but it is not recognised by either my macbook pro or my ipod on my wireless network. It does not show in airport utility. Might I not have an airport card? How would I know. Airport utility in my mac says no other devices connected.

If both your MacBook Pro and iPod are unable to "see" the Wi-Fi network provided by the AirPort Express, it is most likely NOT that you are missing an "airport card," but the Express may be the issue instead.
One quick test is to see if either device can "see" other Wi-Fi networks. If they can, then you can definately rule both of them out as the issue.
By default, the AirPort Express will broadcast an unsecured Wi-Fi network with a network name of something like: Apple Network NNNNNN. Can either device see this network? If not, then I would recommend that you perform a "factory default" reset on the Express, and then, check again.

Airport Card Exists, Shows up in Profiler -- Can't find Any Networks Ever

I've had this problem since November. My Macbook (late 2006 model) has an airport card that is found in the System Profiler. It appears to function as a wireless card. It does not however function for finding a network at all.
I am trying to figure out my options for remedying this. It seems possible that the antennae does not work. If I bought a new airport card would it come with an antennae or is that a separate piece of hardware? I had a third party USB wireless card that I was able to use for wireless access, but it stopped working after a little more than 6 months. I live in a tropical climate and electronics don't always last long here.
Would changing the firmware on the airport card be a possibility? It currently has 1.4.16.2.

I have an iMac G4, airport extreme card was working right, one day the network list just did'n show up. I read somewhere here, the problem might be the antenna of the card...sounds like the card need to be repaired or replaced...

"No Airport Installed" but it came with Macbook & has worked for 1.5 yrs?!

I am not sure if this is Airport Express? It came w/my Macbook, already installed.
It has worked fine w/ no problems till this morning. Was working fine last night. Did nothing but turn it off last night, this morning turned it on, & says no internet connection. Clicking on Airport icon up by clock says only "No AirPort Card Installed."
Followed troubleshooting on this site, which lead me to the Apple Menu, About This Mac, More Info, Network: Airport Card: "No information found." Troubleshooting says this means I need a new Airport Card.
Any idea why this happened? $$ is super short right now- are there any other possible solutions? How much is a new Airport Card going to run me?

I have had the same problem!
Within the 1 year warranty I took my MacBook Air into the store I bought it in as I could not connect to the net due to "No airport card installed" Strangely, when instore, it suddenly worked!
A friend of mine bought a new Mac and I was lucky enough to be given her old IMac, and so did not use my MacAir for a while, when I did, and passed the warranty date, I had the same problem.
It recently reared to life all by itself, without doing anthing. But died again after about a week. I now have too tried all the suggested fixes I can find - nothing works.
This is clearly a widespread problem. You only need search "No airport card installed" and thousands of forums come up. Is anyone from Apple reading these forums? Surely if this is an Apple default customers should be entitled to a replacement, or at the very least a lasting solution to the problem?
I live in Dubai, and unfortunately there is no Apple store here, and no information on this site provides any help as far as support goes for the Middle East!
I am utterly disappointed. My Mac has harldy been touched, and is a rather pricey decoration!
*Try resetting your PRAM and NVRAM - this seems to have worked for some people.*

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.

HT1621 Is there a difference between an airport card for a G3 powerbook and a G4 iMac (Dome)

I have a G4 imac (dome) that I am trying to give to my grandchildren. The internet works perfectly well on my BT set up, but they have Virgin (cable) and it will not connect wirelessly. I think the G4 has a G3 Airport card. I am quite prepared to purchase a G4 Airport card as long as I know that it has different values to the G3. Does anyone have any information regarding these cards.

Guy would this be of any help:
To start up your computer in Apple Hardware Test:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears. If Apple Hardware Test does not start up, see the Additional Information section at the end of this article.
Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
It takes a minute or so for Apple Hardware Test to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
The Apple Hardware Test console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
Your test results will appear in the window in the bottom-right of the console.
To exit AHT, click Restart or Shut Down at the bottom of the window.
