Join a hidden Wi-Fi network
A hidden Wi-Fi network is a network whose name is not broadcast. To join a hidden network, you need to know the name of the network, the type of wireless security, and if necessary, the mode, user name, and password.
Check with the network administrator if you are not sure what to enter.
Click the Wi-Fi status icon in the menu bar, then choose Join Other Network.
If the Wi-Fi status icon isn’t in the menu bar, choose Apple menu > System Preferences, click Network, select Wi-Fi in the list at the left, then select “Show Wi-Fi status in menu bar.”
Enter the network name.
Click the Security pop-up menu, then choose the type of wireless security.
Enter the mode, user name, and password, as required.
The fields that appear depend on the type of wireless security for the network. You may not need to enter all of these items.
Select “Show password” to have the password displayed.
Select “Remember this network” to keep the network in the list of known networks so you don’t have to enter the information again.
The supported security protocols are WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), or WPA2 (Wi-Fi Protected Access II).
