A fix for 10.2.8 updater killing network connectivity System
The 10.2.8 update has a new .kext for Gigabit Ethernet machines. When you install through Software Update, the internet connection may be lost after reboot. I am using DHCP on cable modem, and can't get any IP address other than a 169.254 self-assigned one. Even using manual settings doesn't work. Most people seeing this problem have said they have the dual processor 450MHz G4. The AppleGMACEthernet.kext driver in /System -> Library -> Extensions has been updated from 1.2.4 to 1.3.0. The 1.3.0 version apparently breaks the onboard ethernet somehow. A user posted instructions on how to replace this with the old version, which fixes the problem. Here are two links with more information: [robg adds: macosxhints isn't a news site, and as such, I tend to avoid pretending to try to stay current with topical items ... but this one might have bit quite a few people yesterday before Apple pulled the 10.2.8 update. If so, the above links should at least restore functionality until Apple comes out with the revised updaters.]

Yep, I'm one of the people who this happened to, and I applied the .kext regression fix.

It's working, but I'm a bit concerned.

I'm not a good enough programmer to dive into Darwin to figure out what went wrong, but the source is there for them that are...

I didn't need the old .kext

I didn't have the problem when I rebooted the first time. I repaired my permissions, rebooted again and it was then that I lost my Ethernet connection. Instead of replacing the .kext, i rebooted again zapping the PRAM for a count of 3 chimes and that did the trick.

i'm using two of those dual 450mhz G4's with ethernet connection on both. I updated both yesterday... not a scratch. Still running 10.2.8 on ethernet as we speak. hmmm.

A fix for 10.2.8 updater killing network connectivity
Authored by: mcroft on Sep 24, '03 04:02:38PM

you're probably on a 100baseT or 1000baseT switch. It's the 10baseT connection that isn't connecting.

I talked to a guy who knows the Project Manager for 10.2.8. He says he's the most laid-back guy he knows and he's never seen him this upset.

This is a tough one, because not everyone will figure out how to get back on to learn how to fix their machines.

At least they found out about the problems with these Sawtooth Ethernet chipsets before shrinkwrapping a few hundred copies of Panther. I feel for them, and I have a new suggestion for their compatibility labs.

Apple pulls 10.2.8 update; cites Ethernet problem Zapping the pram didn't help my case, a DP 450 into a 10baseT hub. Rather than apply the kext patch, I decided to wait a bit and see if Apple releases a fix, since I have my laptop in the meantime which still connects to the internet.

Apple Kbase Advice
Authored by: mcroft on Sep 24, '03 05:54:00PM
Apple's advice doesn't include the .kext fix, but gives some good suggestions. If you have a spare ethernet card (I think I have one from each DSL installation...), that might be a good workaround.

You could also just pick up a cheapo 100baseT hub for about $10-$15

that would probably explain it. I read other posts and was shocked at first that I was still on. But decided to ride it out rather than go back to 10.2.6 as precaution no problems yet. Your input clarifies it a bit though.

A fix for 10.2.8 updater killing network connectivity
Authored by: blacksatan on Sep 25, '03 09:53:01AM

Updated my home 450 DP and have not had any problems. Good thing I didn't repair permissions. Updated a work 1GHz DP MDD and there were no problems there either. Then again the MDD is on a 100 bT network. My home one is plugged into a DSL Modem/Router which is probably why there's no ethernet problems since the machine is also seeing a 100 bT connection. Sorry, this post has been no help whatsoever.

Apple has released a new 10.2.8 to fix this
Authored by: blueaudio on Oct 07, '03 12:32:52PM
Just in case anyone finds this thread on a search engine, this issue has been fixed by Apple with a new version of OS 10.2.8 (though you have to use a workaround to restore your internet so you can run the update). The information is on the official Apple site here: http://docs.info.apple.com/article.html?artnum=107669
