Mac OS X 10.4.7 Special Report: AirPort connectivity issues -- fixes
One of the most common issues for users who have applied Mac OS X 10.4.7 is a loss of AirPort connectivity.
One reader writes:
"I also have issues with AirPort after upgrading. My case is such that i do get proper IP address but no transmission. Icon on status bar shows that I am connected to my wireless network with a good signal but nothing works. Turning AirPort off and then on (via the AirPort menubar item) does help."
Another reader adds:
"I'm experiencing the same problems with Airport after the update. I'm getting the internally assigned IP address problem, but only when trying to connect to a wireless A network after a restart. No error on a wireless G network."
Finally, one reader writes:
"I installed the 10.4.7 update from system updater and upon reboot, was returned 'failed to load extension...AppleAirPort2.kext' And now my AirPort is now not working."
Some users are having success restoring AirPort connectivity using one of the workarounds listed in our tutorial "Improving AirPort reception, avoiding dropouts/lost connectivity, working around card/Base station recognition issues", as follows:
- Open System Preferences and select the "Network" pane
- Select "AirPort" and click "Configure"
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Delete the network(s) you regularly use from the list
- Launch the "Keychain Access" application located in Applications/Utilties.
- Click on the "Kind" filter at the top, and look for "AirPort network password" entries. Delete them.
- Restart, or log out then back in.
- Repeat steps 1-3, this time re-adding your regularly used AirPort networks to the list using the " " button.
- Restart or log out then back in.
Some users have also reported that deleting the following file:
- /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
can resolve the issue.
MacFixIt reader Matthew Powell writes:
"I updated my Mac Mini Core Duo from 10.4.6 to 10.4.7 and had an AirPort problem. After a reboot, the machine appeared to associate to the access point, but didn't get a DHCP address. The interface got a self-assigned address instead. The 'Renew DHCP Address' button had no effect.
"I was able to get connectivity back by selecting 'Other...' from the AirPort menu, then re-entering my SSID and password. But connectivity was lost again after a reboot.
"I ended up deleting /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist and the System keychain entry for my AirPort, and then reconfiguring AirPort. I'm still connected after a reboot."

MBP using Boot Camp. Still no joy! Eventually, used the Airport Utility I had
installed on my Windows XP partition to reset the base station software to the
default. Since then, no problems in XP or OS X.
I was having the very same problem with AirPort connecting after reboot only if
manually turning AirPort off and then on again. I worked with a product
specialist from Apple and we tried the "work-around" posted. The specialist said
for me to report that this is not a "work-around", but a "solution."
Thanks.

(3 Comments)After installing Mac OS X 10.4.7 in my MacBook Pro Intell, I had the same
conectivity problem with airport extreme base station. What I did, work for
me. So far my conection still alive and at 100%.
1-Open your base station administrator utility.
2-Click on "configure"
3-Set channel to 11
4-Set mode to 802.11b Only
5-Click on "Internet" tab
6-Write manually the two DNS numbers that appear greyout to the "DNS
servers:" blank spaces. You have to do it yourself, they appear greyout to the
right of this boxes and the boxes are blank, so type them into the boxes
7-Set WAM Ethernet Port to 100Mbps / Half Duplex (unless you have a full
T1,T2,T3) in this case you set it out to Full Duplex
I read this solution in one of the Mac discusion forums, and it is working
more than OK. It's the first time that I can get my full 6Mgps cable connection
for more than a week without problems.
