You should use the TPLink wifi dongle to make use of the wifi connection for the Android system. This can normally be inserted into one of the Android USB sockets on the front bezel. But if wifi does not enable when it is inserted in these sockets please try the USB2 socket on the side of the screen, or the USB2 socket at the top of the screen. On the Android home screen select Apps, then select Settings. A wifi option should be shown in the list on the left. Select this and move the slider to ON to activate wifi. Adjust details and settings as necessary.
