If you cannot access the unit via ethernet, try resetting it, with the power on, by inserting a paper clip (opened up) in the 'reset hole' (back of unit) and holding the 'button' operated for about 5 seconds, releasing it and then allowing it to power up again, then try connecting to it via the ethernet cable and entering the settings required for the WiFi network.
