Airport Extreme Card Upgrade?

Can I do this upgrade myself relatively easily? Also, will it pick up a normal "G" signal or do I need to buy an Airport base station. THANKS!

Adam,
You can do this install very easily following the instructions here. Your AirPort Extreme card will work with any 802.11g signal, so no you don't need to buy an AirPort Extreme Base Station if you already have or prefer to use another 802.11g wireless router.
Let us know if you run into any problems!

Yosemite Upgrade inaccessible MacPro AirPort Extreme Card

Hi
We got a MacPro Late 2009 with a MacPro Airport Extreme Card built in. After upgrading to Yosemite (10.10.2, from 10.6), AirPort Utility Application does not show the AirPort Extreme Card anymore; therefore I cannot access the AirPort Extreme Card for configuration. No AirPort signal either.

Airport extreme card not working with leopard / G5

I just upgraded my PowerMac to leopard (G5 dual 1.8, 3 gigs of ram, 250 GB HD). I bought it new in December 2004 from apple. Previously I had been using a USB adapter to connect to my wireless internet at home (Linksys WRT54G). This device does not support leopard so I got an airport extreme card from gainsaver.com.
The Airport extreme card is configured properly as far as I know but it will only connect to my network for about 5 seconds then it drops. The USB adapter worked perfectly in the same spot and my macbook right next to it works fine as well.
1. Could it be a bad Airport extreme card?
2. Is this a known issue? And possibly be resolved with the 10.5.2 update?
It is a fresh Leopard install with no updates as I can not connect it to the internet to get them. Any help would be very much appreciated.

Hi, I have the same machine (4 ram slots?) have you got the connector for the aerial that connects to the motherboard attached to your airport card. Mine works a treat.

Replacing Airport Extreme Card in Late 2008 MBP - What to buy??

I've limped along for about 2 years now with my wifi constantly dropping while everyone else has a strong, constant signal. Doesn't matter where I am, it's always dropping and takes ages to reconnect. I've tried everything advised on the forum etc and am now about to buy something else as my main machine. I don't want to get rid of my MBP though so am planning on installing new memory and hard drive and while I'm doing that, want to replace the airport extreme card. The MBP will then become my secondary machine.
Problem is, I can't figure out what I need to buy to replace the **** card! Seems like a lot I'm finding are either for machines that never had cards or for 2009 or newer. I just need to know which card to buy.
OR . . . hearing that they are a pain to get to (keeping in mind I'll have the guts exposed while I upgrade the memory and HD) and fiddly . . . is there something external to plug into a USB I should get instead?
Here are my specs:
MacBook Pro, 15" Late 2008 (Unibody)

I'm already upgrading to 8GB of RAM and I'm planning on adding a Solid State Hard Drive since it will be a secondary machine. I really don't want to replace the optical drive too. At that point it's got new components in an old chassis with an old CPU.
I've been to the Genius Bar (back when I lived in a place where there was one in town) and they couldn't replicate the issue but as soon as I left it started up again. There are times when it holds the signal for a good hour or more or days like today when it's dropping it every few minutes. It's completely random.
No. This girl is going to go build her own PC with a fantastic GPU so as to kick some Diablo butt and the old Macbook Pro will only get used when I don't need it for anything serious. And I am most certainly not dropping another $2k + on a new MBP no matter how shiny they are! It's the end of an era as I've been using Macs exclusively for over 10 years now.

What replacement Airport Extreme Card do I need for Macbook Pro 8.2?

It looks like my Airport Extreme Card has failed, although the Blue Tooth is fine. I'm assuming that I need to buy a replacement but am struggling to find what I need. I have a Macbook Pro 15" early 2011 i7 2.2ghz so just need to know what cards are compatable.
It's been a slow failiure, over a couple of months but now it is not even recognised in the System profiler. I am happy to open the case and install a new card, I just need t know what will work. Is there a better card than the original out there, or even an upgrade? I've upgraded the Ram and had to change the HHD already, so as a machine it's starting to resemble the Philosopher's Axe...
Any advice would be greatly appreciated!

Hi Ralph,
Thanks for the speedy response!
I"ve had the case open when I changed the HHD and Ram, and can seen where the card slots in. It's held by a supporting arm which lifts up when disconected from the Logic Board. it's weird looking inside, as you can see there are many of the same componants I've seen in other laptops. It is a tidier build though. I'm confident that if I detach the 3 antener conectors and remove the retainer screws a new card will fit back in.
The Genius Bars here in London are highly over subscribed, and I don't think I have the time or budget for that.
I'll keep plugging away, and see what happens. I'm almost getting used to being tethered to the Ethernet cable. I've only tripped over it 20 times a day!
Take it easy.

Can't get security to work - Airport Extreme card and Netgear router

This apparently is not as simple an issue as I expected, so I would appreciate some help.
I just got dsl and a Netgear WGT624 wireless router to connect my wife's iBook G4 with AirPort Extreme card. I used a wired-in pc to set up the router via the web interface and can connect the iBook to the web wirelessly as long as I have security disabled. When I attempt to set WEP or WPA the connection fails.
Initially, I assumed I just was missing something in the AirPort setup, even after looking through all the documentation I could find. I upgraded yesterday from 10.3.3 to 10.3.9, just to see, but had no improvement.
If I select "WPA-PSK(TKIP)" in the router, it asks for a password, which I also then enter to login to the selected network via Internet Connect. I get "there was an error joining..."
If I select "WEP" with 64 bit and shared key options, use the same password to automatically generate the assorted keys, I am not sure what to enter to login. I have received incorrect password messages or no response at all.
I would appreciate any further direction or suggestions.
Thanks
iBook G4 Mac OS X (10.3.3)

One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
Though sometimes not even that works and the HEX key must be used regardless.

"WPA Personal" on the Mac corresponds to plain WPA, with a pre-shared key (PSK) and TKIP encryption, on non-Apple wireless routers. The same alphanumeric password should work on both.

Airport Extreme Card Install

I recently inherited a PowerMac G5 (approx. 5 years old) that does not register having an airport card. After purchasing an airport extreme card and opening the box to install it, I found a card already in the slot that does not look like the card I bought and is bolted in and cannot be removed. Does anyone know what this is and how I can remove it?

Hi-
I found a card already in the slot that does not look like the card I bought and is bolted in and cannot be removed. Does anyone know what this is and how I can remove it?
From your machine profile (11,2) you have a dual core 2.0 GHz machine which uses a special Airport Extreme/Bluetooth card on a runway card:

http://support.apple.com/kb/HT3096
Don't remove it unless you have the card from the kit that I linked. You can't use a regular Airport Extreme card.
This is the card needed:

i have an imac g4 purchased Dec 2003 runnung OS 10.5.8. It runs fine with airport off, but when I turn airport on it freezes with the black page, "restart by holding power key . . ." I swapped the airport extreme card with the one in my ibook G4 (purchased same date and running same OS). No change in operation.
I am running wifi from verizon. Recently changed from mifi2200 to jetpak 4620 in a 3G location. Ibook running fine, desktop freezes. If I can boot desktop in safe mode and get airport turned off in time. then I can reboot regularly and imac runs flawlessly with no wireless.Have run disk utilities and TechTool Pro rebuild etc, but nothing has worked. How do I fine the culprit?

the power logix thing was really sad. apple changed so much after 10.4.8 that there wasn't a viable way to patch the software.
That statement is precisely why I don't believe in blindly updating the OS, especially in a non-standard machine.
We can't expect third parties to support us forever, and it is shameful to break something that works fine, except that we updated the OS....
I think that any upgrade or modification to a machine or the OS greatly increases the risk of trouble or incompatibility with current configuration and "new" system files.
After all, the component or software could only be tested as far as the current OS version when the component or software was released.
Beyond that, we are all "beta testing".
Following a beta tester protocol, and applying updates to a cloned system drive first, is a prudent way to approach updates, and not only for older, heavily modified machines.
After 10.4.8 and moreso with Leopard, the focus is primarily on Intel architecture, not PPC architecture.
Like it or not, we are all updating to the abyss of the extinction of our machines, unless we can be satisfied with the last stable version of OS that works well with our hardware and software.
I wish they would include the latest pkgs at least with software update.
Yes, having individual packages, rather than lump "OS X 10.x.x" updates would be nice.
This way, one could update as one sees fit. That is to say, for example, fix the Quicktime, but leave my Network alone, etc., etc.
In all fairness, Apple does provide for some breakdown of updates, but I believe there is much room for improvement, especially, as you point out, with regard to the core services portion of the OS.
Until then, I'll leave Software Update disabled.......

20-in Intel iMac (early 2006) Tiger -- configuring Airport Extreme Card

Hi -- I come from a mostly "not mac" background and am having difficulty diagnosing a slow internet connection -- and can't tell if I'm trying to use the right tool for the job. (I am using MAC OS X 10.4.11)
My home network uses a Linksys WRT54G wireless router and I've got 3 computers that connect using the router (including the iMac) -- the other two are Windows-based machines. We've got a 2-story house and I've been moving the router and computers around the house a bit trying to come up with the best configuration for a good wireless connection (I'm going to be ordering a supplemental antenna, but don't have it yet).
The two Windows machines (one using a relatively old PCI wireless card) get strong signals. I'm not even sure how strong a signal the iMac gets as I am not sure which utility allows me to see this. I do know that it has a painfully slow connection speed (at least web pages load at a crawl...).
I've got an Airport Extreme Card (0x14E4, 0x89). Firmware: Broadcom BCM43xx 1.0 (4.170.46.9).
I went to Apple's support downloads, and attempted to install firmware updates, but I am getting a message that indicates that these updates are not applicable to my card. I updated the Airport Utility software, but as far as I can tell that utility is looking for an Airport Extreme base that I don't have. Other than that I haven't seen any applicable information using that utility.
I was hoping to reach a configuration area that would allow me to specify 802.11b or g, and allow me to specify the channel -- but other than in the internet sharing section I don't see a place that allows me to do this. (I've currently got our home network on a 802.11g network on channel 8.) We're using WPA personal encryption -- which does appear to be recognized by the Airport Extreme card.
Am I missing something? I've got 3 "Airport" utilities but none of them seem to allow me to specifically configure the internal card. I've gone to "network" under System Preferences, and although I can see a "configure" button when I click on "Airport," it's pretty basic and doesn't allow me to set the channel or anything other than encryption & a password.
I would appreciate any help you can give me. Is this card so outdated that I should invest in a newer one? Am I limited by my outdated OS? (I hesistate to upgrade OS's when things are working -- in the Windows environment at least newer isn't always better...) Thanks. mcaren

Thank you Duane for your response.
I have only noticed a huge difference in the connection speeds of my iMac and our other computers in the last 6 mos. to a year. I did notice an improvement in speed when using a Rosewill USB wireless adapter -- I had a good wireless signal but would intermittently lose connectivity (and their user support was basically nil...).
I can't tell if I'm actually seeing an improvement in our other machines' connection (perhaps from the tweaking I'm able to do) or if in fact the iMac is slowing significantly. I think it's the latter. I've actually swapped out machines in the same position to see if location is at fault -- and I get no improvement in connection speed. I've had the iMac connected with ethernet to our router when possible because it has had such a slow wireless connection, but I needed to move the router recently and would like the iMac to stay in another room.
I've also read a lot about connection speed issues with Airport, but these reports are usually blamed on Leopard updates (there might be similar Tiger issues, but I don't read about them...).
Oh well. I'm hoping someone out there has some tricks up their sleeve as to how I can improve my wireless connection speed. Thanks for the help! mcaren

AirPort Extreme card and Netgear

I hope someone on this group list can help. I've been around the web (MacOSXHints, etc.), and on the phone with Apple (for hours) trying to find a way to link my brand-new iBook G4 to the Wintel office system. They've got a Netgear wireless router (MR814v2) and Windows 2000.
Here's the thing: my iBook G3, with an AirPort card, can pick up the network's broadcast, and I can go surfing the web & connect with our printer over Apple Talk. My G4 with an AirPort Extreme card can recognize the presence of the router, but is unable to surf it's airwaves. I've already tried connecting directly via ethernet cable, and this works - but won't be an option for day-to-day. Per some hints on the web, I've gotten the IT guys to upgrade the netgear's firmware to 5.03, but it STILL doesn't work. Apple says it's a Netgear problem, but the IT guys won't change the router (my D-Link at home works great), and they are loathe to tinker with the settings (esp. because they've set it up to have a dedicated line for electronic billing submissions).
So, has anyone encountered this problem yet? Any good work arounds? Thanks, all.

Thanks for the welcome, Duane. Yes, the network does have an access control list, but the while the router is picking up the MAC number on my G3, it can't seem to see the G4, though the G4 can see it. Is the suggestion that I convince the ITs to manually input my MAC Address? Maybe that's a go, if we can do it manually.

Airport Extreme Card is weak

I have 2 questions. First, is there a firmware upgrade for my Airport Extreme card version 405.1? Now to my main question. Is there a reason why after 2 years of working perfectly that my wireless connection has gotten weak? When it was working correctly, I had a good connection from the other end or my house. Now I don't even hold a good connection across the room, about 10'. This is with an Extreme base station. I also tried a linksys connection while visiting family in North Carolina and I had to sit right by it to get any connection. Do these cards occasionally go bad? Thanks for any help.

jerryg233, Welcome to the discussion area!
First, is there a firmware upgrade for my Airport Extreme card version 405.1?
No that is the latest. All firmware updates are downloaded automatically when AirPort/system software updates are installed. There is no user notification nor notification.

Airport Extreme Card missing after Leopard and Login & Keychain Update

After these updates the network prefs showed no Airport card installed, even though it had been there seconds earlier. This was buried at the bottom of a posting for a similar problem. Just wanted to make it easier for others to find.
"I'm having the same issue with an iBook G4 1.2Mz model. Having successfully installed Leopard (5 user license version) on my Macbook, I installed it on the G4. At first this worked until software update installed Login & keychain update 1.0 and Remote desktop client 3.2.1. When the iBook reset the airport extreme card wasn't there. The icon in the menu bar states No Airport card installed."
"Some users have determined that an artifact left over from Mac OS X 10.4.x interferes with wireless connections after Mac OS X 10.5 is installed. The issue can be dealt with by finding and removing the AppleAirPort2.kext file from your Extensions folder, located here:
Macintosh HD:System:Library:Extensions"
That fixed it for me.

Judging by the amount of posts it must be isolated. Mine works fine. Did you repair permissions ?
" Keychain-Administration or Privilege Issues after Upgrading to Leopard:
If after installing Leopard as an upgrade or archive and install you experience any issues with not getting mail, can't run Disk Utility, can't login as administrator, can't print or anything that entering existing User name and/or passwords requires, you are not alone and Apple is working on it now.
The fastest method of determining if you have been bitten by this, open System Preferences, click on Accounts and verify that you are the Administrator as opposed to Standard, and that the checkbox asking if you want this user to be an Administrator is checked. If you are Standard, and the box is unchecked and/or greyed out, you have a situation most likely, whether you know it or not, yet.
Further verification can be done in the Accounts window by clicking the lock to make changes, entering your name and password and being denied access.
Apple says the best thing to do right now is not to try too much voodoo and wait until later today for a solution, hopefully. I was told to close the lid and walk away until Apple calls me back.
The good news as I write this on my old reliable Pismo, is that I have a bootable Carbon Copy Cloned 10.4.10 complete back up on an OWC external FW disc. Thanks Mr. Bombich! I just hope I don't have to use it.

Which slot for the airport extreme card?

I just picked up an airport extreme card for my mac pro. I located the slot in the mac pro, but there are two on top of each other.
Question: which slot do I have to use: the upper or lower one?
Iemke

Thanks for the answer, however inserting the card was
not the difficult thing. Finding the correct wire for
the antenna was the difficult thing. A apple
certified technician helped me with that issue.
Iemke
I want to buy the mac Pro and install the airport extreme card - what is the model number of the new card (apple tech tell me it is different from the old G4 card of the same name) and which is the correct wire to attach it to?
BTW I know my way around the G4 desktop having upgraded &/or replaced everything screwed down in those
this knowledge will speed up the purchase process-thanks

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?

Is Duel Ethernet Airport Base compatible with Airport Extreme Card?

I am about to upgrade to the new Macbook Pro 15" from my Titanium G4. I currenty have the original Airport card and the dual ethernet Airport Station.
Question - will the new Pro with the Airport Extreme card be compatible with the old base station?
If it will, what would be the advantages of upgrading to a new Extreme Basestation?

magicnme, Welcome to the discussion area!
Question - will the new Pro with the Airport Extreme card be compatible with the old base station?
Yes, the MacBook Pro can connect to a 802.11b base station like the Dual Ethernet (aka snow) AirPort base station (ABS).
If it will, what would be the advantages of upgrading to a new Extreme Basestation?
The AirPort Extreme base station (AEBS) offers a USB printer port for wireless printing.
The AEBS offers WPA and WPA2 wireless encryption.
Also if you have other computers on your local network, large file transfers between your computers will be faster.
