Today i setup WPA2 security with AES on my Linksys router and when i connected to my wireless router my gnome-keyring prompted me for a keyring password to authorize the use of a key, i could not remember if i had chosen one. I tried many passphrases that I could think of but to no avail. I would just choose deny and it still worked.
I did some searching and found out how to reset or clear the keyring so that i could put a new password in there. I chose my login password and now it no longer asks me. Below is what i did.
Navigate to Places > Home. Press ctrl-h for "hidden files". Navigate to .gnome2 > keyrings. Delete login.keyring file.
At this point your gnome-keyring should be cleared and you can reset the password on next use. Just logoff or reboot.
