A fix for 10.2.8 updater killing network connectivity
Sep 24, '03 10:48:00AM • Contributed by: blueaudio
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.
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.

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

I'm firing my proofreader.
Another webpage just for reference
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
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.

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
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:
