Airport Card Disappeared After Turning Airport Off

I successfully used my MacBook Pro to connect wirelessly to the 'net for 2 hours, then turned Airport off for security purposes. I came home and tried several times -- unsuccessfully -- to turn Airport back on (to use my home Airport Express.) The wireless transmitter was functioning, as established by a successful connection by my iPhone. I rebooted and attempted to turn it on several times -- no joy. I tried removing /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist and restarting, and the menubar icon (and About This Mac - More Info) claim that no Airport Card is installed. It seems unlikely that the card would die just because I turned it off. Any ideas?

What Mac are you referring to? (Part of your info at the bottom should at least say what model). Turning it off for security purposes? In any case check System Profiler>Network>Airport Card and see if it shows up there. You might want to post in your Mac model specific forum area.

HT4628 I did the security update on 4-2-13 and now my airport card will not turn on. OS 10.6.8 Intel imac 4,1 core duo. My macbook pro did not have this issue and wifi here is working on that. Is there a setting that was changed? Thank you!

Airport card will not turn on after security update yesterday. worked normally (for the download of the update) until then. Wifi here works fine with my Macbook Pro right now so the issue is with the card / computer / software not the provider. Did the update change something?
OS 10.6.8 imac core duo. The indicator is on the tool bar but is empty.

Airport card disappears in OS9?

Hello all
I just acquired a G4 cube. It has 640MB RAM (more is on order) and a stock 16MB video card (got a new one on the way...) and the Airport card. I just did a clean install of OS 9, and updated to 9.2.2. The entire system, including the Airport card works flawlessly under Tiger (I'm using it to type this message), but the Airport card disappears in OS 9. On initial boot in OS 9, the Airport card will show up, with four "bars" of signal in the control strip, showing it is connected to my home network (which is temporarily secured with WEP, so it will play nice with OS 9 - I've also tried it with an unsecured network). However, whenever I try to actually use the network (software update, web browsing, whatever), the bars go blank, then the Airport icon greys out and disappears. I click on it and get the message "there is no Airport card installed". Occasionally, it gives me a number "3278" and nothing else.
I don't know if this is related, but OS 9 feels a LOT slower than it should on this G4. Tiger runs a lot smoother and faster, yet there is considerable mouse lag when dragging the pointer across the screen, and a definite lag when opening applications or documents in OS 9.
Any ideas on why I can see my Airport card in X and not in OS 9?
thanks,
Rich

OK, more weirdness...
Before I received our last message, I got a strange error - I came back to the computer and there was an error box saying something like "This computer can not go to sleep because it is missing some of the system software. Please reinstall the system software.". Gulp! Sounds like a corrupted OS install...so, I wiped the drive. I repartitioned it (120GB WD drive - 4096MB for OS 9, the rest for X) and formatted it using the OS 9 disk utility software. I then booted from the "Software Install" disk and let 'er rip. I wound up with an OS 9.1 partition...and...all of the original Airport card problems were back!!! I tried to put the machine to sleep, and got the above error again.
So I reformatted again, and this time used the "PowerMac G4 Cube System Restore" disk, which reset everything to factory defaults from a disk image. Again....no Airport, and no sleeping due to "missing system software". What in the name of the Force is going on here...?
I am now running extended Apple Hardware Tests and will report back.
Of course, everything works perfectly in OS X, so I'll probably just let it live in Tiger land...but this is seriously challenging my Mac geek cred...LOL
And just a side note - OS 9 installs SO much more quickly than X! I've been able to completely reinstall twice now in rather little time!

Internet not working after turning Airport on

Hello,
All of a sudden, I can not connect to the internet when I turn the Airport on. The signal looks strong. But when I open my browser, it gives an error page. On a cafe where there is a free wireless internet that I go to often and had no problems connecting, gave me this message recently.
IP Configuration
192.168.1.46 in use by 00:18:39:88:81:fc, DHCP Server 192.168.1.1
Is there anything that I need to update in my Airport settings? If so, where? I have been trying to look for that and don't seem to have any luck.
Thanks for any help.

2630 keeps discharging after turning bluetooth off

On regular use (i.e. without using bluetooth), I can use my Nokia2630 for several days without recharging. Sometimes I use a bluetooth headset connected for about an hour and then disconnect the headset and turn bluetooth off. The bluetooth indicator disappears, but the battery keeps on discharging and is empty after less than 12 hours.
If I turn bluetooth off and turn the phone off and back on again, there is no problem.
Summarized, after turning bluetooth off, the phone keeps using a lot of battery power.
Is this a techical failure, firmware issue, ...
Suggestions pleas?

I think might the bluetooth manager did not shutdown properly. and so judging from that, the battery depleted very fast but the battery indicator might not detect it as quick as it should. It happens all the time. Even my phone does.

Ipad2, I can not sign in to imessage after turning it off and doing a hard reboot. Upon entering my info it states no network connection, but I can use it o surf in Safari and iter websites. Any suggestions. Went on with Apple, they think its my network.

Step by step, how did you arrive at seeing this agreement?

Panther - Airport card disappeared

1. Recently we installed a new iMac on our home net using the same wireless modem we were using for our Emac. . After it was done, our old Emac which worked perfectly up til then cannot join the netwrork. It says there is no airport card. If you go to network it shows airport is off, you cannot turn it on. Anyone have an idea what might have happened to cause eMac to lose the airport card? Threads in discussions on airport have suggested zapping the PRAM but my understanding is that in Panther the Network settings were not stored in the PRAM.
2. Can OSX Leopard beinstalled on a old (2002) Emac? Would installing the new system possibly revive the airport card?

Alas, the current AirPort Extreme cards are unsuitable.
If you're confident, you may want to check to see if the AirPort card currently installed has become dislodged, there's no reason, other than a drop (or someone removing the card) that it would stop working.
Otherwise you have three choices,
- live with an Ethernet connection, but this might not be possible.
- an original AirPort card, from somewhere like eBay. They used to cost a fortune, more than the value of the eMac, but they're reasonable now.
- a wireless router, that supports WDS (wireless distribution system), or wireless bridging in particular (which is a subset of WDS). And preferably a wireless 'n' model over a wireless 'g' version.
You would then connect this by a short length of Ethernet cable (probably come in the box with the wireless router) and configure it to operate as a wireless bridge. This would mean the eMac would use its Ethernet connection to communicate with the WDS wireless router, which would then communicate wirelessly with whatever wireless you are trying to connect to with the original AirPort.
A second hand original AirPort card might set you back $30-$60, a WDS wireless router (from new) might be $70-$120. The AirPort Express is a $99 WDS wireless router, BUT it has a minimum OS requirement to configure it, OSX 10.4. Most manufacturers make WDS wireless routers, Netgear, Linksys, Belkin and Zyxel are adequate.
If you go for the AirPort Express (or Time Capsule which offers similar functionality but more demanding OS requirement) it has first rate instructions available on the Apple site. No matter which (if any) model you get, there would be adequate instructions once you understand that you are setting up the router as a "remote" WDS (other choices are "main" or "relay").
AirPort Express main page is here:
http://www.apple.com/support/airport/
You may want the designing networks manual here (the link is on the page above):
http://manuals.info.apple.com/en/DesigningAirPort_Networks10.5-Windows.pdf
In particular, the WDS setup section starting at page 42, with the exact step-by-step details on page 44 - called "To set up additional remote devices".
But here's hoping that you find either the card loose or the wireless antenna (thin black cable with screw in connector to attach to the card) loose when you open the eMac and check it. All you need is a Philips screwdriver and the manual:

Airport Extreme disappears after waking from sleep.

Here is a strange one for the experts out there...
I recently purchased an Airport Extreme card for my G4 Powermac (FW800). It is the Broadcom BCM43xx 1.0 (4.170.25.8). It installs easy, and it works great. I can connect to my Airport Express with no problem, and to my 2009 MacBook.
The problem occurs after the computer goes to sleep. After I wake it (even if it's only after a minute), the Airport Icon disappears and the Spinning Beach Ball of Death appears over the title bar, and the dock. I can click on windows and move them, but not use them.
If I use the Special Menu and tell the computer to sleep I don't have any problems. I'm using the latest update for Leopard, but this happened with Tiger, too.
Any thoughts?

I had this problem just recently and seem to have fixed it today. I made the following changes:
I changed security from WPA2 to WPA using the Airport Admin Utility.
I went to the Network Preferences panel and found that the network was still listed as WPA2, so I deleted it.
I then added the WPA network to my preferred network list.
The computer now reconnects automatically after sleep or shutdown.
I don't know whether changing from WPA2 to WPA was necessary. It may be that all you need to do is delete and re-add the network.
Hope that helps!

Airport Express Base station turns itself off

I recently had an airport express base station that died completely. Apple replaced it on warranty. Now my new base station behaves very erratically. After a while without activity, the airport turns itself off. The only way of getting it back is to unplug the power and plug it in again. This works most of the time, but sometimes I need to repeat several times or reset it as it locks itself with a steady yellow light and my computer cannot see it. I guess one could live with this if it wasn't for the fact that my DSL modem (Motorola) and base station are kind of hidden and difficult to access...
I have had airport express wireless networks for several years and this kind of behavior was never a problem before. The new base station has the latest firm ware, it was updated just a few days ago.

To Apple Discussions!
Suggest that you post over in the AirPort Express Forums. It's where the AP users hang out.
"Now my new base station behaves very erratically."
I would give Apple a call first.

No Airport Card Installed after factory restart

I tried a factory restart on my Airport Express after having some slow connection issues. Now I show "No Airport Card installed" Is it likely my Airport Card is dead?

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.

The airport card won't turn on

Sometimes, after awaking the computer from sleep, the three bars are gone and the triangle is there but is bare. Then I cannot turn on the airport card from touching the triangle or network preferences. I have to restart the computer, which always works.

Is this problem present no matter which of the LAN ports you use?
Have you tried using a different ethernet cable?
Does this Mac connect quickly if you cable its ethernet port directly to the cable modem?
What IP addresses are list on your Mac, when connected via cable, for the built in ethernet port?

"No airport card installed" after 10.5.3 Update

Hello everybody,
after an obviously successful update to 10.5.3 on my MacBookPro the system doesn't recognize the integrated airport card anymore. Reboot or anything else doesn't solve the problem. Getting online is not longer possible via airport. Did anybody experience the same problem an found a solution?
Thanks in advance!

"No Airport Card Installed" After 10.5.6 updgrade...

After I installed the 10.5.6 upgrade using software update (from 10.5.5), I no longer have an airport card detected. It does not show up in system profiler either. Is there anyone that knows why this happened and how to fix it?
Thanks, Mechmess
I'm on a model MacBook4,1

I've had this issue - if you have AppleCare, call to log a support case. They will have you reset the pram, which worked for me. However, I was told it may happen again, at which time they will replace the airport card, so it sounds like there may be a known problem with the cards.

"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.
