Apple released AirPort Client Update for MacBook and MacBook Pro 1.0 late on Tuesday to address Wi-Fi reliability issues some users were experiencing after installing the Mac OS X 10.5.8 update. The update is available for specific pre-unibody MacBook and MacBook pro models.

Apple's AirPort Update for Pre-unibody Laptops
The update addressed performance-related AirPort issues when running on battery power. Late 2007, early 2008 and late 2008 13-inch MacBook owners, along with early 2008 15-inch MacBook Pro owners, and early and late 2008 17-inch MacBook Pro owners can install the update.
AirPort Client Update for MacBook and MacBook Pro 1.0 is a free update, and requires Mac OS X 10.5.8. It is available via Apple's Software Update application.

The update fixed my Airport Extreme speed problem in the sense that with or without the power adaptor, I get the same speed (around 6 on speedtest.net) but I’m still nowhere near the 12 or 13 (again speedtest.net) that I was getting back in April. Does anybody have any idea what change would have slowed down a 2008 MacBookPro 15 / 2.4 ghz on an Airport Extreme Base Station?
Thanks,

I’m having Airport issues with my unibody MacBook. But, no software updates for it yet. :(
I am having the issue with a White 2009 model. I tried to install the update but it said my hardware is not supported for it. Hope this gets fixed soon. I am now only getting half of my speed as before. Booting into windows on the same computer works fine.
I started out with the same problem with 10.5.8 on my early 2008 macbook pro. However, I just installed this update and now the airport ethernet interface can’t log in to my AirPort Express base station via WPA2… It sees it, can configure it, but gets a “Connection Timeout” when authenticating. All my other computers work fine. :-(
