Access denied on Motorola cable modem router

I have 2 cable modem routers, 1 upstairs, 1 downstairs, due too my home is built hurricane proof and the WiFi single doesn’t reach(even with pods).  I have a new xfinity router that works fine upstairs.  In the downstairs for a couple years I’ve had a Motorola cable router and last week the internet connection stopped working.  When I Iogin to the router I see “Access Denied” on one of the status settings. And my Motorola doesn’t exist on the My Devices page of the xfinity app.  Was the connection terminated by Xfinity?
