I have a question, my dad just replaced our old modem with a mesh system. One of the modem thingies is right next to my room, but I'm afraid i might break something if i connect an Ethernet cord to it, because the downstairs thingy is also using an Ethernet port. Would it break if I connected an Ethernet cord to it while the downstairs modem thingy is also using its Ethernet port? (I'm a teen by the way, so I have no clue what most of the stuff is called or how it really works)

Whether attaching an Ethernet cable to the unused Ethernet jack on the mesh unit would work, depends on the particular model of mesh unit and what the jack is used for. If the jack is labeled WAN or MODEM, it won't work to connect to your computer or console... but it is very unlikely to break anything. Even if something goes haywire, just unplug your cable, temporarily unplug power to the mesh unit, and then plug power back in to the mesh unit should restore everything.

If the jack is labeled LAN or SWITCH, then it should work for a wired connection to your computer or console.
