When I reinstalled Ubuntu, I logged in on my wifi and authenticated with a password that seahorse saved in "Default". But I want that in "Login" so that I won't have to enter my password twice everytime i reboot, how can that be done?
cd ~/.gnome2/keyrings rm login.keyring mv default.keyring login.keyring echo -n "login" > default
(You may not need the last line, and I backed up the login.keyring rather than deleting it).
This worked for me.
From Network Connections.
Click on my Wireless that you connect to automatically when you boot up. Click Edit. And at the very bottom it has a box to make the connection available to all users. Check that box.
