Airport Extreme card won't connect

eMac 1.25 GHz (USB) trying to connect to Linksys WRT54G router
Purchased an Airport Extreme card on eBay.
It sees router immediately, but when I try to connect it gives the extremely informative message:
" There was an error joining the Airport network "(name)"
I have a number of other Macs and PCs and my Blackberry and my son's iPhone that can successfully connect, but not this beast. I have reinstalled the card several times with no success. I'm guessing it's ok since it sees my router immediately. I've entered the password 100% correctly. I've even reconfigured the router not to require a password. Same thing. In desperation, I've even tried reconfiguring the eMac to use only 1GB RAM after seeing that suggested for a similar iBook problem. No help.
So... how do I determine what the "error" was that's preventing connection? And how do I fix it?
Any suggestions welcome.
Thanks,
Rich

As this is not too likely to be an problem specific to eMacs, you may get more responses by posting in the Airport forums here:

Airport extreme card won't connect to internet. Says cable unplugged.

I have an aiport extreme card in my emac. It was installed around a year and a half ago and has workd fine until yesterday. it suddenly says that it is not configured. It also says the antenna cable is unplugged and that it is turned off. I tried to trouble shoot it with internet connection assistant which says cable is unplugged and aiport is off. I have taken the card out and reinstalled it and reattached the cable mutiple times to no avail. And yes, I know how hard it is to push in. Any ideas? Thanks. Shannon

Airport Extreme Card won't run 802.11n

I have an AirPort Extreme card (0x14E4, 0x90) Firmware Version: Broadcom BCM43xx 1.0 (5.10.131.36.1) in a MacMini Intel Core 2 Duo 3,1.
Using a Billion 7404VNPX wireless router, the card will only run on 802.11g.
At the same time, I've fitted a 3rd party wireless g/n card to an ancient PowerMac G4, and it runs perfectly happily on 802.11n
Can someone suggest how to make the card do what it's supposed to do?

Sorry, but that card can only run 802.11b/g, so it really is doing just what it's supposed to.
Well, if that's the case, perhaps Apple should improve the System Profiler reporting. Here's what mine reports for this card:

Hmmm....wonder if I can get a refund or replacement?

PB's Airport Extreme card not staying connected - please help diagnose

My thread Airport extremem card can't hang onto wifi signal - what to do? in the "Getting Online" forum hasn't generated a solution, so I'm trying here too.
In the past few weeks, my airport signal bounces around and randomly disconnects me. It goes from no signal (indicated) to 3 bars then bounces around. It occurred with my own Airport Extreme card (in the PB) and my Belkin router, and the library's wifi.
The problem may have started after an erase-and-install of Panther with an upgrade using the combo 10.3.9. The only security updates I see receipts or packages of are SecUpd2005-004Pan.pkg, SecUpd2007-002Pan.pkg, SecurityUpdate2004-10-27Pan.pkg.
The usual troubleshooting (Permissions, Chrons, Disk Warrior) didn't solve anything. Since first posting about this problem I've reapplied the 10.3.9 combo. I tried changing the channel on the router and setting it to Protected Mode.
"Protected Mode
NOTE: In most situations, best performance (throughput) is achieved with Protected Mode OFF. If you are operating in an environment with HEAVY 802.11b traffic or interference, best performance may be achieved with Protected Mode ON."
I then installed Airport 4.2 update because Software Updater presented it as an option.
Until today iStumbler and MacStumbler were showing 29-35% signal strength with no noise. As of today, iStumbler is showing intermittent noise of ~14-21%, but MacStumbler is not. (It was constant when I tried channel 9 and changing the router's back to 10 made it intermittent.)
The router is serving a desktop computer via ethernet so I can't move it. I have reset the router and cable modem several times with no improvement.
Does anyone have any ideas what I can do? Thanks.

I would have come back to edit this, to say that the dropping signal problem came back since the 10.3.9 combo but I couldn't. The darn wifi signal was lost for something like 7 minutes.
The PB was sitting in exactly the same place and toggling airport on and off wouldn't reconnect it. It generated many lines in the console. Anyone know what this means?

Airport Extreme Card can't connect to wireless network

Hello All,
I recently installed an Airport Extreme Card into my PowerMac G5, but am having difficulty connecting to the existing wireless network. The card appears to be installed correctly, and Airport comes up and says it's running, but doesn't see any available wireless networks. An iMac 5 feet away (and no closer to the airport extreme base station) connects perfectly. With all the info about the antenna, i've triple checked to make sure the antenna is completely installed in the card so I don't think that is the issue. It's part no. M8881LL/A Model No. A1028 and it's installed in a PowerMac Dual 2Ghz PowerPC G5. I'm wondering if there is a compatibility issue? Any comments?
Thanks for the help.
PowerMac G5 Mac OS X (10.4.8)

Hi Duane,
Thanks for the welcome and the reply. The PowerMac is an older one so I don't have the external antenna, and have looked around for one with no luck. I just ordered one and it will be here tomorrow so I'm hoping you saved the day and that's the ticket. Thanks so much for the help! I'll update this again if that solves my problem, but just wanted to say thanks... i'll know more on Monday.

Airport extreme card is not connecting automatically

I've installed an airport extreme card on my Mac Pro, but every time, I have to go to "network" and connect manually... any ideas? It's my only network and the "remember networks" is checked.

Hi!
Sounds as though maybe your AE wireless card may have failed;
and if you've tried more than a few times to re-seat the card into
the slot and had no results, you may see about trying the card
in another compatible computer to see if just the card is bad.
You may be able to swap out the part to restore wireless access;
but I am not sure of any situation that may limit your recourse
through the reseller of the card you now have. They may not take
it back, in other words. But to find out if the issue is your AE Card
or some other potential issue is an important pursuit. So, if you
can, perhaps a reseller of new parts can let you see if a new card
will resolve this issue by trying a new card and see if it shows in
the System Profiler; and if access to the internet is available nearby,
to also see if it connects readily.
Good luck and happy computing!

Hard Drive attached to Airport Extreme (AC) won't connect

I cannot connect to my USB hard drive which is connected to my new Airport Extreme (Wireless AC) router. If I unplug the hard drive, it seems to work for a bit. Then for unknown reasons, I am unable to connect to it.
It worked in 10.8 fine, I never had any problems until I just updated to 10.9 yesterday.
The official error I get is: "There was a problem connecting to the server 'Airport'. Check the server name or IP Address, and then try again. If you continue to have problems, contact your system administrator."

Two things to check:
1) The drive must be formatted in Mac OS Extended (Journaled). Use Disk Utility in the Applications > Utilities folder to verify.
2) The USB port on the AirPort Extreme is not a high powered port like you have on a Mac. It is often necessary to use a powered USB hub with any drive connected to the AirPort Extreme....even if the drive has its own power supply.
See this recent thread to verify:

AirPort Extreme Card recognizes networks but won't connect - HELP!

hello forumites,
firstly, if this post is similar to one that has already been well-read and widely responded to, i apologize and ask that you respond with the link to said thread.
my issue pertains to an iBook G4 (circa 2004 i believe) running OS X 10.4.11 with an apple-installed AirPort Extreme card (firmware version 405.1). i have never had any problems with the card previously, but in the last week it has quite suddenly ceased to connect to any wireless network i attempt to log on to (both password protected and non). despite the card's sudden inability to connect, it still is able to recognize all the wireless networks in my location (i know this as the networks are still listed in the AirPort status pull-down menu).
in an effort to fix the issue i have:
restarted the card (turned it off and on)
restarted the computer (many, many times)
used the network diagnostics program
used the network setup assistant program
attempted to connect through the system preferences (network)
attempted to connect through internet connect
did a complete erase and install
still nothing.
anyone had a similar problem? anyone find a way to fix it?
thanking you in advance for your brilliance and time,
brad

firstly, tesserax, a tremendous thank you for your help. unfortunately, i tried each step you suggested, but the problem continues.
step 1: i have tried and failed to connect to several different networks in a handful of locations (home, work, friend's house, local coffee shop, etc.).
step 2: i have disabled my own wireless encryption as well as the wireless encryption at a friends house, however, to do so i had to use their ibook, as my own either didn't list the base station in the AirPort utility (although it did list the base station in the AirPort status pull down), or it asked for a password even though the base station wasn't password protected (maybe this may add some insight into the issue?).
step 3: i have connected the computer directly to the modem using an ethernet cable and was able to go online - perhaps this means the problem is related solely to the card.
step 4: i moved the the com.apple.networkConfig.plist file and and the SystemConfiguration folder to the desktop and restarted. unfortunately, OS did NOT rebuild the files. instead, i had to go through the network diagnostics to rebuild them manually. while the files were replaced, the problem was not solved.
step 5: i reset the PRAM, but the problem still exists.
step 6: i reset the PMU, but the problem still exists.
i then tried various combinations of your suggestions, including moving the files out of the preferences folder and then reseting the PRAM and the PMU, but still nothing.
after having attempted every fix i could think of (and that was before posting to this forum) i did a full erase and install of the OS. since that's usually the cure all to whatever ails the computer, it's my assumption that the issue is a physical (hardware) one. that said, if you have any other suggestions i will be more than happy to give them a shot.
thanks again,
brad

IMac G5 Airport Extreme Card WEP/WPA Security connection Problem

I have an iMac G5 (non Intel) and a wireless Belkin 801.g MIMO router. When I have no security setup on the router (ie straight out of the box)then the Airport Express card connects to the network without problems. As soon as I set either WEP or WPA or WPA2 security on the router and input the correct settings in the Airport configuration in system preferences the card sees the Network but will not connect. I simply get the message "error connecting to network". I have a Windows based laptop with built in wireless card and this has no problems at all connecting to the secured network, whether it is WEP or WPA or WPA2. Does anyone have any thoughts or ideas please?

I have the same problem with my new black MacBook and a Netgear router. I can connect to the 'free' networks all around me, my Airport Extreme card sees the wi-fi network in my home that I want to connect to, and my old iBook with its lowly Airport card connected (and still does) with no problem using the '40-bit hex' option when entering the password. But now all of a sudden there are just 'errors' when I try to connect (having tried all the various options, and two different types of passwords or keys as provided by the network administrator). Oh yeah, and of course Apple Support won't help because they don't want to know about problems relating to third-party technology... We can't be the only ones with this problem!

Computer won't recognize Airport Extreme Card

Okay, I need a little help. I bought an Airport Extreme card for my eMac today, which is what my manual told me I'd need to connect to a wireless Internet connection.
I followed the instructions to install it exactly, but the computer won't recognize that it's there. It still says "no information available" when I go look at the Airport card settings.
I'm not sure if it's a fault of mine, the card's, or the computer's. When I insert the card, should it snap into place? Should it slide out easily? How can I tell if it's in properly?
If anybody can help out, it'd make my year. I am dying to get this high-speed Internet set up. Thanks.

surfingbaku, Welcome to the discussion area!
Use the information in KB 86325, eMac: How to locate the serial number and identify your model to identify which type of eMac you have.
If you have one of these eMacs
eMac (ATI Graphics)
eMac (USB 2.0)
eMac (2005)
you require the AirPort Extreme card.
Any other eMac requires the original AirPort card.
If you are using the correct card and it is not being recognized, one or more of the following must be correct.
The card isn't installed correctly.
The card is defective.
The eMac's motherboard is defective and not recognizing the card.

IBook G4 won't start up after installing Airport Extreme card

Hi,
just installed an Airport Extreme Card into girlfriends iBook G4 (10.4.5), which now won't start up. After pressing the start button all I hear is the fan spin (pretty fast actually), but nothing else happens.
When I remove the card the iBook starts up normally.
Any thoughts what could be wrong? Bad card? Bad connection?
Thanks a lot

Sven, Welcome to the discussion area!
Are you certain that you have an AirPort Extreme card?
Are you certain that it is an iBook G4? The iBook G3s require the original AirPort card.
If both of those are OK, then one (or more) of these is true:
The card isn't installed correctly.
The AirPort Extreme card is defective.
The iBook's motherboard is defective.

Can't Connect to Internet using AirPort Extreme Card and DLink Router

I have tried just about everything, but I can't seem to connect my MAC OS X 10.3.9 to the internet. I am using the Airport Extreme Card and no networks show up. I am trying to connect to my DLink router. I was told by DLink that it is compatible with AirPort Extreme cards, but the guys at Best Buy were unable to connect to their wireless routers, other than their Mac Router. Please let me know if you have a solution! Thanks

dannabee, Welcome to the discussion area!
What Mac do you have?
Do you have iMac G5 or a Power Mac G5?
Did you install the AirPort Extreme card yourself?

I have a iMac with a built in airport extreme card. Does the imac act as a wireless router so that I can connect to the internet from my iPad by tethering through my iMac?

Depends which iMac exactly and your network setup, you can go into System Preferences and under the Sharing pane you can enable internet sharing from ethernet (or whereever you get your internet from) to Wi-Fi.
