How do I "unpause" a device without xFi?

I own my own modem.  Because of this I can NOT use xFi.  Somehow my daughter's phone became "paused" on my wifi.  When I try to open a webpage on her phone I get a message saying that "this device is paused."

I have no idea how this happened as her phone worked fine just a day or two ago.  The solution that Xfinity's bots keep suggesting is of course to go into xFi and unpause it... which I can't do. 

Anyone have any suggestions?
