keyring nightmare

Good day. I an new to Ubuntu and run 9.04. I set up a secure wireless connection to the internet a few weeks ago, and entered the required password for "unlock keyring", which was the same as my logon PW. My wireless hub has a separate hex PW. Everytime I logon to my pc I'm prompted for the "key ring" PW to enable my wireless connection - I find this quite bothersome.

Recently I changed my logon password, however, the keyring application does not accept my new password. I've tried deleting and reinstalling the wireless network using my new password, however, I get dialog box from "unlock keyring" :

The application "nm-connection-editor" (/usr/bin/nm-connections-editor) wants access to the default keyring, but it is locked. It prompts for a password, and it will not accept my new password, however, my old password is accepted and the wireless connection to my internet hub is completed.

I would be obliged for any help in getting the keyring application to accept my new PW. Many thanks,
