Hello. My name is Michael. I can help you with your question.
The way you set up the scanner is to connect to it first as an access point - as though the scanner were your network. Then from the device that you connect to it from, you go to the IP of the scanner http://10.10.100.1 and then setup the scanner for your actual network.
After doing this, you can connect to your network again and then you will be able to use the scanner.
