When the wePresent software fails to connect, but results in giving an IP address of 0.0.0.0, please check that you are indeed connected (by Wifi or network) to the wePresent. If you are indeed connected, please make your computer disconnect, and forget the current (Wifi) signal. After this, please reconnect again (by Wifi) and start the software anew. If this still does not work, please check if you are using the latest firmware and software. If the wePresent is not reachable after you have adjusted the network settings, you may have set incompatible settings. If you do not know how to solve this, please connect directly by LAN-cable and set the device back to default through the Admin menu.
