Orbi RBR50 and Spectrum - having strange issues.

Issue 2:

Why would the Orbi not be seen as connected to the modem?

This may be semantics.  "See" in the sense of "There may be something connected, but I have no way to access it, much less say anything about it."

Issue 3:

What could be attracting the DoS Attacks?  The ports they are scanning are at the end of the list and high port numbers.  (Ill add a screen shot). And what is the best method of stopping them?

There are programs running that constantly scan every public IP address looking for open ports and attempting to connect. They cannot be stopped, just as there is no way to prevent people from calling your phone number (robocalls).  You can choose not to answer, which is what the Orbi does.  The Orbi firewall has routines that attempt to classify connection attempts in various ways. (I have seen comments claiming that Netgear is overly-aggressive at identifying "DoS" attempts.) The two Orbi systems that I get logs from identify at least 80 "DoS Attacks" every day.  I repeat, the Orbi rejects these connection attempts, just as I do not answer most phone calls.  There is no harm in 'hecking the option on the Advanced Tab WAN Setup "Disable Port Scan and DOS Protection."

Once Remote Management has been activated, the Orbi actually does accept connections (the default port is 8443). When programs find port 8443 is accepting connections, they attempt to log in.  This will fill the Orbi log with "Invalid Login" messages.  With my 25 character Orbi admin password, it will take about 8 billion years for someone to gain access.
