To connect to a hidden wireless network:
1. Click on NetworkManager in the top panel.
2. Select Connect to a hidden wireless network. Ubuntu will then open
the “Connect to Hidden Wireless Network” window.
3. In the Network name field, enter the name of the network. This is also
known as the ssid (Service Set Identifier). You must enter the name exactly
how it was given to you. For example, if the name is “UbuntuWireless,”
entering “ubuntu-wireless” will not work as the “U” and “W”
are both uppercase in the correct name.
4. In the Wireless security field, select one of the options. If the network
is an open network, leave the field set to “None.” If you do not know the
correct setting for the field, you will not be able to connect to the hidden
5. Click the Connect button. If the network is secure, you will be prompted
for the password. Provided you have entered all of the details correctly,
the network should then connect, and you will receive an on-screen
notification informing you that the connection was a success.
As is the case with visible wireless networks, hidden wireless network
settings will be saved once a connection is made, and the wireless network
will then appear in the list of saved connections.
