No connection after installing Security Update 2005-007

I would try a Single User startup, run fsck -fy and then ZAP the PRAM... That worked for me... I had EXACTLY the same problem...

I tried that and I thought it worked by the fix was only temporary. The problem is back and I am not using Airport. I am having the problem with ethernet connected.

When the connection is lost, PING and some other network commands still work. Netscape also continues to work, but Safari and Entourage can't connect to servers.

I was having the same problems after the Security install. I zapped the PRAM, I repaired the permissions, and now - the computer won't even start up! The apple comes up, then it turns to a circle with a slash through it. AHH!!!
Any ideas?!

I wouldn't have done all this, but I rarely restart my computer, and I was having to restart it every time just so I could get on to my airport/internet.

Ok, I managed to be able to reboot the machine using an OS9 startup disk - All I did was go to Control Panel, and under start up - I chose OSX, rebooted, and it started up fine. I then restarted and started up in single user mode - ran the /sbin/fsck -fy until it gave me the volume OSX is OK - reboot - from there I immediately zapped the PRAM. Upon letting it start up again, I went back into the grey circle/slash mode. I popped back in the OS9 startup, managed to boot up again.

Now, my Airport isn't even appearing at the top of my screen. When I go into my Network prefs, it says Airport is off. When i show Network Port Configurations, the Airport and Built-In Ethernet settings are greyed out - Internal Modem, IrDA Modem Port and VPN are the only items in black, that I could possibly work with.

I tried repairing permissions again, restarted - and still the same thing. Have I missed anything?

To Joseph,

try a "factory reset" on your airport base station itself (if your running airport extreme). I twice did it and when it comes to configuring it you have a completely blank new setting to start off from.

Before you do this Also do a "find" for ANY "plist" that has be "modified" with the last week or so! Trash those that are relevant (ensure you state "visible and invisible")

It was some struggling but my machine is running perfectly now . And yes, there are differences in the communications (as my PC is networked with my Mac and I had to toatally reset and change the settings on the PC, too.

I still think ,it's a ploy to make people by Tigger 🙂

Thank you Alexander.

I finally broke down and upgraded to Tiger. This didn't help at all, which left me scratching my head and looking elsewhere for the problem. The reason it was so puzzling was that Tiger worked fine on the other powerbook.

So, I upgraded the firmware on the Linksys router (WRT54G) and that fixed the problem.

After encountering the same problem on my powerbook g4, I did the following:

1) from a Terminal window, get a listing of the running processes using ps -x
2) Look for the /System/Library/PrivateFramework/Apple80211.framework listing and note the PID numer for it.
3) kill the first of the processes listed that meets that description.
4) You should now be prompted for the "keychain access" change, which you should accept.

It should then connect to the airport and be able to browse the internet.

This is dam perfect!!

I had the problem again after installing the latest set of updates, followed your procedure and it works perfectly!

Apple must now be aware of this problem for non Tiger systems, can't they sort out the updates so this doesn't happen each time...?

Thanks again anyway!!

I had the same problem, running 10.3.9 on an iBook, couldn't connect to the internet via AirPort even though it appeared to have 5 "bars".

Started by trying Mike Jagger's method (above) but the process wasn't running on my computer for whatever reason. Zapping the PRAM worked, though. I skipped the fsck.

Thanks for the advice (and no thanks to apple!).

I should mention- the update appeared to have wiped my update installation history (in the software update system preference). It didn't do it to my boyfriend's computer that's running Tiger.

Having this problem on my wife's iBook (G3, 600, 10.3.9) but there's no 80211 process to kill. I've tried resetting the PRAM, but no luck.

I found this problem after installing Security Update 2005-008 onto my Ibook G4.
I used this fix and it worked like a dream.

Thanks

OK, if you go to the 'Process Manager' Application in the Utilities Folder in the Application Folder. Find the Process called 'Airport' and tell it to 'Force Quit'. Then turn off Airport and then turn it on again... Choose your Wireless network from the menu and it should ask for access to the keychain... GOOD LUCK...!!!

I'm getting the same problem when I tried just normal ethernet, and now with a third party usb wi-fi adapter. Is the same problem affecting theses too? It tells me that it is connected, but it has a self assigned ip address and can't connect to the internet.
