I recently bought an S33 earlier this month (link). But I am unable to get it activated through Xfinity despite numerous phone calls and having a tech out to my home. They were confident that the modem was bad. Is there any way to tell if this is true? I took some screen shots from the Web UI.

Is there anything listed here that would indicate if the modem is bad? Or is the ISP at fault?
Thank you!
