10.4: A fix for Motorola wireless cards under 10.4.2
Authored by: sethd on Oct 13, '05 07:13:09PM
10.4.2 didn't just break 3rd party wireless cards. My Airport Express in my Powerbook G4 12" had very shaky performance until I replaced the airport kext files with the versions from 10.4.1. The key topic in the discussion forums is here. Here are the instructions from "HR":
The issue is software. I just took the airport kext files back to 10.4.1 and all is well. Signal strength is comparable to our Titanium Powerbook (a bit lower than an iBook or our Sony but not an issue). My signal strength without the repeater went from 0% to 5% in a far bedroom to 40% to 45%. With the repeater on, its back to 85%. The PBook now flows seamlessly between the router and the repeater as the 10.3.9 laptops have always been able to do. We have a fairly large cement block house with plaster walls laid over metal lathe. The router is at one end and the repeater at the other. Not an 802 friendly environment. If you do purchase the Powerbook and need the 4.1 files, here: http://fabounio.free.fr/bidouille/airport.zip I would stress that you do the following prior to installing: Back the 10.4.2 files to another drive/flash memory/whatever. I put them in a folder on the desktop and they were no longer there after I rebooted. Although I did not need them it was a bit disconcerting to lose the original files before I knew the 4.1 files would do the trick. Overwrite the files, you will need to authenticate. You must run permissions. Reboot. Done!
I also offered to host the 10.4.1 files on my webspace:

My backups were mysteriously missing, so make sure you have your backups on a separate drive or archived just in case. And don't forget to repair disk permissions!
