First, you need to connect the MF885 to a laptop via a USB cable. We just need the USB connection momentarily to bypass the Wi-Fi network.
Once the MF885 is connected to a laptop, open your web browser and type in http://192.168.21.1
This will take you to the admin page of the MF885. The default admin password is zimifi
After you log in, you can navigate to find the Wi-Fi network and password settings.
