You may use a radio on the WiFi Pineapple to connect to an external WiFi network, for getting an internet connection or for communicating with other devices on that network.

To configure a client mode connection, navigate to Settings > Networking in the User Interface. You will be presented with a card labelled Wireless Client Mode.

After clicking the Scan button, a list of surrounding wireless networks will be listed for you. Select the SSID you wish to connect to, and enter the SSID or PSK if required. Click Connect to start a connection.

If the connection is successful, you will be presented with the associated SSID and an acquired IP, if DHCP is enabled on the network.
