Connect to a Wireless Network [Official Ubuntu Help]
If you have a wireless hardware switch on your computer, make sure that it is turned on. Click the network menu in the menu bar, and click the name of the network you want to connect to.
If the name of the network isn’t in the list, select More Networks to see if the network is further down the list. If you still don’t see the network, you may be out of range or the network might be hidden.
If the network is protected by a password (encryption key), enter the password when prompted and click Connect.
If you do not know the key, it may be written on the underside of the wireless router or base station, in its instruction manual, or you may have to ask the person who administers the wireless network.
The network icon will change appearance as the computer attempts to connect to the network.
If the connection is successful, the icon will change to a dot with several bars above it. More bars indicate a stronger connection to the network. If there aren’t many bars, the connection is weak and might not be very reliable.
