Leopard doesn't save my Airport settings!

[MacLovin611]

So whenever I add a new airport network or add passwords, Airport fails to connect. Next time i check it, the profiles have lost their passwords and the settings are reverted to ones that I didn't choose. I installed the Keychain and Login update and I still don't know how to fix it. Can anyone help me save my Airport preferences?! please!

Have you downloaded the "Leopard Keychain Update"? Methinks that your mac can't access Keychain properly to use the passwords.
