Hello user_6hvd9a. Thanks for reaching out to us for help with the connections. I'm happy to help out to help the two devices to communicate. If you are using a modem (without a built-in router/wifi connection) the issue is that the modem is not capable of being a networking device and will probably end up allowing one device internet access with the other device not being able to connect to a network. A quick way to usually tell what capabilities the modem has is if there are 4 or more ethernet connections on the modem. 

Are you using a Xfinity wireless gateway or did you purchase your own modem and router?
