I’m finding it a little hard to follow your description sorry, but couldn’t you do something like: Outside Internet -> Modem -> Router -> network switch -> devices?
Sounds like you just might need a network switch with more ports.
And I feel like it’s not a good idea to have a modem directly attached to the pc directly unless you’re using it as a router?



Because when you’re writing something for a large ensemble and you need them to play the right notes and rhythms there needs to be a standard way to notate music. Otherwise you waste time teaching individual parts.
And it does mostly make sense. It’s just that there’s room for interpretation.
