A window will then pop up prompting you to enter the name of the network manually, and to select its security type from a drop-down menu option. To add a network, click the plus symbol (+) under the list of preferred networks. This is the window through which you'll be able to add or remove a network, or reorder your network preferences.

Once these steps have been completed, click on the 'Advanced.' button on the bottom right of the window. Make sure you have 'Wi-Fi' selected on the left-hand side, and that the status bar says 'Connected.'

From there, click on the 'Network' option toward the middle of the screen.
