The only way I was able to resolve this problem on my MacBook is by restoring the OS to a previous stable version (10.6.3).

No internet via Airport. Can someone please point me to a FAQ as to how to turn the software back? Undo the update, so to speak?
I am assuming this is the only fix.
Please help.

Get the installation disc from the previous stable version. Put it in the DVD drive. Restart and hold down the c key. Go through the installation process.
