I don't know anything abut Optimum - just what the websites
says-- a .net & .com both related to it..
https://www.optimum.net/support
and http://www.optimum.com/


If you ask the set up person, they probably will set it all up for you..

They may use a router that is both 'wired' and wifi ours from frontier works both ways...
so it can be a plugged in or wifi which ever works for your uses..
