Airport Installed But No Signal

Hi, I'm having connection issues with the original airport card in my imac. It previously worked and now is not. Perhaps you can help. Here's my troubleshooting process thus far:
1. Airport card is inserted securely and antenna is connected.
2. Airport status is greyed out in task bar. Internet Connect shows absolutely no signal strength.
3. My iBook G4 sits next to iMac and is able to connect to my router as well as detect other networks.
4. PRAM has been reset. Disk permissions have been verified and repaired.
5. For a brief second, the airport icon in task bar detected three neighbouring networks, but not mine. However this was very brief and no networks show up now.
6. I had both computers connected previously via ethernet. Now each computer is unable to access the other's drop box. I'm also only able to connect as a "guest."
7. I tried to create a wireless network between both computers to no avail. However, when I created a network on the iMac, signal strength suddenly went to full.
I think that's about it. Any help would be greatly appreciated.

Per your numbering...
(1) Since the time it worked previously, have the card and adapter been removed? Or have they been installed in the iMac and not touched since that time?
(2) Make sure you do not have +Internet Sharing+ (set to share Ethernet using AirPort) enabled. Actually, turn OFF +Internet Sharing+ in System Preferences Sharing pane for now. Disconnect anything connected to the Ethernet port. In System Preferences Network pane, Show *Network Port Configurations* and make sure AirPort is at the top of the list. You may also want to turn off the services you do not use for networking, such as FireWire and Internal Modem. If you made any changes, be sure to click +Apply Now+, then restart.
(4) Did you also try reseting the PMU. This is the procedure
http://mrjcd.com/junk/PMU.jpg
If you have a voltmeter, check the PRAM battery if possible. If you disconnect the iMac from power for a while, that probably serves the purpose of the PMU reset as well. When the iMac is reconnected to power and stared up, do not connect any peripheral (USB/FireWire) devices, except standard keyboard and mouse. Try the AirPort connection again.
Also, try starting up in Safe Mode
http://support.apple.com/kb/HT1455
This will run some maintenance during startup. It will also start up with only Apple's essential system extensions and processes running; try using the AirPort connection again in Safe Mode.
(6) That may be an unrelated problem. Can the iMac still access the Internet using a wired Ethernet connection?
(7) If the iMac can still connect to the Internet using Ethernet, what happens when you go to System Preferences Sharing pane +Internet Sharing+ tab and turn ON +Internet Sharing+ ? Set it to +Share your connection from *Built-in Ethernet* To computers using AirPort+. Then, try to use your iBook's AirPort to access this wireless network created by the iMac. Does that work?

"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.*

Airport plugged but no signal

Hi,
I have just recently plugged a Airport extreme card into my G5 dual processor in the available slot. we have a network that has been set up for a while and has worked well on the 6-7 laptops that are networked to it.
the problem i have is that although the G5 now recognises it has an airport card it doesn't pick up the network even though we have updated the base station with the G5's airport card info.
the only thing i can think of is that the antenna is faulty as it seems to be plugged correctly.
if anyone can help or has had similar difficulties i would appreciate any help
thanks
alex

If you'll take a little time to peruse the most recent posted discussions, you'll notice that hundreds of people are experiencing the same problem with equipment that was working properly prior to these recent updates. For some reason, Apple has refused to respond to these queries even though we all know that they are fully aware that this is a major problem.
Perhaps if you and the rest of the public will continue to post questions regarding the recent airport firmware updates (or any updates relating to it), then maybe they'll eventually HAVE to respond. But for the time being, they're unreachable. I certainly hope you'll have more success than I've experienced.

I have a internet connection thru a cable modem but the signal is not strong to reach one of other rooms, so i purchased a airport express so how do i connect it to the exisiting modem do i have to install the cd that came with it, the modem is connected

Hello:
This article will give you basic guidance.

I have an old airport express, but the software on my computer does not accept it. I need to downgrade the software, but the older software will not install.

I have a old G4, I want to give to my son. It does not have a wireless card and because his room is on the second floor it is impossible to connect with a wire.
I wish to add an airport express to my airport extreme network and connect the computer and the airport express together with a cable. Is this possible?
second question:
software does not install.
I do have a network with a airport extreme and want to add the old airport express to it. I want to do this with airport software, however the software tells me the airport express is to old and i need to reinstall older software 5.6 to be precise. However installing fails, so I thought i just remove the airport software, but osx does not allow me to do that.

i managed to install the older airport utility and am trying to set up a connection with an existing network, but airport utility cannot find the airport extreme AFTER it starts up again. I then went and again restored it to its factory settings and did the whole procedure again with airport utility, but again after utility tells the airport express to restart it does not come back.

AirPort quits unexpectedly and a reboot is necessary to get it back. I installed the most recent AirPort software, but it didn't resolve the issue (v10.5.8). Has ideas? Thanks in advance.

Open a Finder window. Select MacintoshHD in the Sidebar on the left then open the LIbrary folder, then the Preferences folder, then the System Configuration folder.
Move all the files from the System Configuration folder to the Trash.
Restart your Mac. Try AirPort.

I have a Power PC G4 which is running on OSX 10.5.8, it has the AirPort utility but cannot connect to the internet as my iMac can, I think I might need an AirPort Card? Is that the case or do I need something different to connect to a wireless modem?

Welcome!
Only one variant of the PowerMac G4 could use the faster Airport Extreme Card. The rest used the original Airport card that is pretty slow.
To get fast wireless without buying more than one thing, consider this:
http://eshop.macsales.com/item/Edimax/EW7722IN/
It goes in an available PCI slot
There are USB solutions also. However, all PowerMac G4 towers had only slower USB 1.1 ports, so any USB wireless adaptor can only run at about wireless 'B" speeds (slow) unless you also install a PCI USB 2.0 adaptor card. Doing that would allow a USB wireless adaptor to run at its maximum rated speed. These items working together would accomplish that:
USB wireless "dongle:"
Newer Technology MAXPower 802.11n/g/b USB Adapter + Plug and play direct or with extension cradle
USB PCI adaptor:
http://eshop.macsales.com/Search/Search.cfm?Ntk=Primary&Ns=P_Popularity%7c1&Ne=5 000&N=7069&Ntt=USB+PCI
Each approach has its advantages. The PCI wireless card is a one-piece solution that takes up no desk space. The USB2 card+USB2 Dongle gives you more fast ports for transferring date from other external USB devices (primarily cameras and external hard drives) at hugely faster rates than can the original ports. I have a USB 2 PCI card in my G4 tower strictly for transferring images from my digital SLR camera in a timely manner.

I own an imac 2011 running osx 10.6.8. I want to the new airport extreme. but it says in the system requirements that it needs osx lion 1.7.5 or later. would it work with my older osx 10.6.8?

In order to set up and install the new AirPort Extreme:
Setup and Administration
iPhone, iPad, or iPod touch with iOS 5 or later and AirPort Utility 1.3
Mac with OS X Lion v10.7.5 or later and AirPort Utility 6.3
would it work with my older osx 10.6.8?
Yes, if you set up the new AirPort Extreme using the guidelines above. The 10.6.8 Mac will be able to connect to the AirPort Extreme, but it will not be able to make any configuration changes.
Only the devices listed above can be used to set up and make any changes to the new AirPort.

MacBook 2008 wifi suddenly stopped working and says no wifi hardware. Took it to an apple shop, they said it could be the airport card but wouldn't do anymore then that. Any help on how to fix this? How do I know if it is the airport card or not?

If the technician at the shop is competent, he has given you a diagnosis that should have identified the problem. You could run the Apple Hardware Test to verify the findings:

Note the Apple Hardware Test is not definitive.
Go to the iFixit.com and Powerbookmedic.com web sites. They have parts and installation instructions. To install an Airport card is fairly easy.
Ciao.

I'm trying to setup a printer go wireless through my airport extreme, but every time I try to print the printing file gets paused. I'm in loop. PLEASE HELP! (The printer is a Brother 7020 monochrome)

I had the exact same problem
It turns out I was using a 20 foot USB cable between the printer and the Airport Extreme and the signal had become to weak to work. Try using nothing more than a 6 foot cable or try a new cable

Can my Airport Extreme recieve a signal from another AE?

I'm buying a new iMac that will have an Airport installed in it. I want my old flat panel iMac 800Mhz G4 to now be wireless. Can I just connect the AE via ethernet and Bam be connected with my old iMac.
I asked a question earlier about a USB connected wireless reciever instead of installing a airport card. But it looks like the USB external ones are a little unreliable.
Thanks!!!

Waldarsky, Welcome to the discussion area!
I don't know how you ended up in the iMac (CRT) G3 discussion area since you question has nothing to do with that.
I'm buying a new iMac that will have an Airport installed in it. I want my old flat panel iMac 800Mhz G4 to now be wireless. Can I just connect the AE via ethernet and Bam be connected with my old iMac.
I think you are asking... Can I use the new iMac;s built-in wireless to create a wireless network and then have the AirPort Extreme base station (AEBS) wirelessly connect to that network and allow the iMac G4 access to the Internet via Ethernet?
If that is your question... the answer is NO. OS X's Internet sharing is not compatible with WDS. Without WDS an AEBS can not wirelessly join a network.
The same is true if you were to use an AirPort Express (AX) instead of the AirPort Extreme base station (AEBS).
However if you were asking... Can I buy an AEBS and use it to connect my new iMac wirelessly and old iMac G4 via Ethernet? The answer is yes. The AEBS supports both wired and wireless clients.
If I totally misunderstood, please clarify...

Retina MacBook Pro is not connecting with Airport Extreme 5 GHz signal

I believe I have done my due diligence to find the answer to my question here and other places but I must be missing it. I have a Retina MacBook Pro that as far as I know should select the 5 GHz signal from my Airport Extreme (Generation 1 with 7.6.4 firmware) which is literally 3 ft. from my computer. When I click on the Airport icon in the menu bar, it is indicating a 2.4 GHz connection. I have looked at discussions which say I can give separate names to to both the 2.4 GHz and 5 GHz signals. I can't seem to find that. I also read where you can reorder the order of signal preference. I can't seem to find that either. Interestingly, I have an Airport Express that is extending the network. When option clicking on its icon in airport utility, I can see both the 2.4 and 5 GHz information. I don't se that in the Airport Extreme. I am thinking about gettng the newest Airport Extreme but if I don't need to...
Thanks for any help!

as far as I know should select the 5 GHz signal from my Airport Extreme (Generation 1 with 7.6.4 firmware) which is literally 3 ft. from my computer
A Generation 1 AirPort Extreme is not a simultaneous dual band wireless router. It can produce either a 2.4 GHz....or....a 5 GHz wireless network signal, but not both simultaneously.
If you want the Gen 1 Extreme to produce and deliver a 5 GHz wireless network, it can do so, but any 2.4 GHz devices that you have will not be able to connect to the 5 GHz signal.
A new simultaneous dual band AirPort Extreme will produce both a 2.4 GHz and 5 GHz signal simultaneously. Wireless devices will automatically connect to the best signal quality based on their capabilities and location in relation to the AirPort Extreme.

HT1998 My iPAD can use the internet through my airport extreme, but the airport utility does not see it so I can't create a guest password. What am I doing wrong?

My iPAD can use the internet through my Airport Extreme, but the Airport Utility does not see the device so I can't set a guest password.

If your Mac is using the Lion operating system with recent updates, it will be necessary to download and install AirPort Utility 5.6 for Mac OS X Lion
Open Macintosh HD > Applications > Utilities > AirPort Utility 5.6
Select the AirPort Extreme and click Manual Setup
Click the Wireless tab just below the row of icons
Click the Wireless Network Options button
Remove the check mark next to Create a closed network
Click Done, then click Update to save the new settings and allow 25-30 seconds for the AirPort Extreme to restart

I bought a airport-extreme but the software to program only works on Windows 7 to get it to work. Any work around?

I bought an Airport-Extreme but the software to program it only works on Windows 7 and above and I have an XP? Any work around?

Have you tried AirPort Utility 5.5.3 for Windows
You need to have XP SP3 installed on your PC to run this version of AirPort Utility.
