When I log into my computer, networking is disabled. I always have to enable it so I can connect to the internet. Does anyone know how to set it to enabled by default?
From the network-manager applet menu (right click), select edit connections. Edit the connection you wish to automatically connect and select the connect automatically checkbox.
If you wish to start a connection before you log in, select the available to all users checkbox. This is most useful with wireless connections which usually are available only after login.
