RBK50 Dropping Internet

Thanks so much for the quick reply.  I am with a company that provides fiber optic service and there is no separate router.  The signal comes directly from the wall into the router.  Not completely up on the tech side of that, but in short no modem.  There is what they call an ONT (Optical Network Terminal) box connected to the house and the signal comes into the home ready to connect to a cmputer or a router.  Again, I used the Orbi for years with no issues and it started when I turned Armor on.  Fiber is fantastic as I get gigabyte speeds for less cost as my previous cable internet provider (Cox).  Again, thanks for the reply!
