Connections can then be edited by clicking on the icon, selecting Network Manager, then Edit to open the settings manager. Also, notice the icon changes its appearance once a connection is established. A common feature that is enabled automatically is to have the connection in question automatically connect as soon as it is detected.
Connection problems can be notoriously difficult to diagnose, especially on a system that is not able to make a connection at all. If these steps fail, the best advice we can give is to get on a system that does make a connection (or use a wired connection if wireless is failing) and join us on Discord or the Bodhi Forums.
