Home Forums Networks & Cross-Platform Networking wifi problems after installing 10.6

I'm not clear--did you add your network password only in Keychain, or did you do it in the Network Preference panel as well? I think it needs to be in the latter, otherwise Keychain may not know what to associate with that particular password.

Alternatively, in the Network Preferences, delete the home network and then create it as a new setting all over again and see if that fixes the problem.
