After the Snow Leopard update I can't connect to my home wifi router.
I removed it from Network Preferences and from Keychain but when I reconnect it will not ask me for the password.
All other wireless networks that I had configured previous to the update still work and all other computers work with my home router (mine did before the update).
I want to find the file where those password are stored to check its permissions or remove it and have the computer ask me for the password again to hopefully fix the issue.
