TICKET ARCHIVE -> Clean Install of Tiger, Problems With Airport Express & Airport Card
krugz - Aug 27, 2005 - 12:44 pm
I just upgraded from Panther to Tiger, I'm fairly familiar with the OS, but I've just had The Most Frustrating thing happen... twice. After I ran my new iBook G4 for awhile, I was trying to network my boyfriend's Windows XP machine and oops, I assigned his comp the IP address my comp was getting automatically. Suddenly my G4 decided that it no longer had an Airport card. At all. Not even in System Profiler.
I clean installed Tiger and re-migrated everything. Again, no problem getting online. Then this morning my surge protector tripped, Airpot Express restarted, and I couldn't get online. Nor could I find the network OR the Airport itself in Admin or the menu bar or System Prefs. So I fiddled and fiddled and reset the Airport and finally also restarted my comp. Lo and behold... no airport card!!!!!!!
I can't do another clean install... I already did a clean install on my old comp for my sister... Help! Right now I'm connected directly from my cable modem to my ethernet jack.

Mac OS X 10.4.2 Special Report: AirPort connectivity issues
Solutions
Reverting to older AirPort kernel extenstions One potential workaround -- which has worked when this problem appeared with previous iterations of Mac OS X and various security updates -- involves reverting to older version of the AirPort kernel extensions.
This can be accomplished by first downloading the shareware utility Pacifist, then obtaining the AirPort 4.1 updater package.
Use Pacifist to open the AirPort 4.1 package, and extract the following files:
Place these same files in the /System/Library/Extensions folder, replacing the old copies (you will be asked for your administrator password) and restart. You may need to repair permissions using Apple's Disk Utility (located in Applications/Utilities after restarting).
Crisp Hues is one MacFixIt reader who had success with this workaround:
"My original problem was AirPort causing my wireless network (Linksys WRT56G router and adapter) to stop working after 10.4.2 on my G5 dual 1.8 tower. The fix I've used is to downgrade to the AppleAirPort.kext and AppleAirPort2.kext files to the ones the ones that came with 10.4.1. and then repairing permissions. I got these files from the Apple Support Forums. Don't have the link anymore. It worked. Probably not a fantastic solution but seems good until Apple addresses this problem."
Delete then re-establish wireless network MacFixIt reader Arno reports that you may need to delete then re-establish any encrypted AirPort network configurations in order to take advantage of Mac OS X 10.4.2's enhanced automatic reconnection capabilities after sleep or restart.
Arno writes:
"I found out that is best to delete all preferred networks with encryption. And then add them again after manually connecting. Fastest way is temporarily turn on 'Automatically add new networks to preferred networks list' under 'Options' of the Airport network connection.
"After that, the problem with not reconnecting after sleep or startup was solved for me. Finally! It was most annoying with closed networks (hidden SSID)."
"Change Settings" on Base Station For some users, simply using the AirPort Setup Assistant (located in Applications/Utilities) to "Change Settings," then re-entering configuration information restores connectivity.
One reader writes:
"I had the same problem and fixed it fairly easily by running the Airport Setup Assistant and choosing 'Change settings on an existing Airport Base Station' and re-entering the previous (same) info as before."
Turn Base Station off, then on In some cases, turning an AirPort Base Station (or AirPort Express unit) off, then back on -- usually by unplugging then re-connecting to power -- re-establishes proper operation.
MacFixIt reader Scott Daniels writes:
"After installing the Mac OSX 10.4.2, I also got the error connecting to airport network message - from all three machines on the network. Fortunately, the solution was quite simple: I unplugged the two Airport Express base stations that comprise my wireless network (home), and plugged them back in again after a few seconds. Problem solved."
You may also want to try turning your internal AirPort card off then back on if you are having access issues. This can be accomplished through the AirPort menu item, or using Internet Connect (located in the Applications folder)
One reader writes:
"I have a 1Gz G4 Powerbook and following the update and restart, Airport stopped working so I turned off the Airport and turned it on again. I received a message which asked if I wished to update passwords in my keychain, when clicked 'OK' my Airport returned.. Hope this is useful."
"Keep Looking for recent networks" MacFixIt reader Jerry D reports that, in his case, selecting "Keep looking for recent networks" in the Network pane of System Preferences resolved his inability to connect to local networks.
Jerry writes:
I experienced a consistent problem in that every time I started up or restarted "I had to go into Airport Utility and run through set up each time. After fighting this for 2 or 3 weeks and futzing with settings over and over, I hit on a setting that cured this (maybe everybody already knows to check this setting, but I didn't) - In Network Preference, behind the Options Button - I had to select 'Keep looking for recent networks' under 'If no recent networks are found' - That fixed this issue."
Switching channels In some cases, switching channels on your (non-AirPort) WiFi base station can improve reception weakened by incremental updates.

My problem was 2 parts... I eventually got the airport working, I just needed to reset it. The other problem was that my airport capability wasn't working. I finally gave in and took it to the apple techs at my school (uconn) and they discovered that although Bluetooth was working, Airport was not. I swapped my comp out and now I have a brand new one that works.
Thanks though. =)
