I am thinking of buying a something for my room for wired connections to my PS4, Raspberry Pi and other things. I know some stuff about how routers and modems work, but do I need a modem if all I am using is ethernet wired connections?
Alright, thanks!If you're strictly using the hardwired connection to get to the internet, just make your internal network faster than your Internet connection speed. If you want to do anything between two or more of your internal devices, go for the fastest hardware you can afford, up to gigabit. 10gig hardware is not really viable for home networks yet
As for if you need a modem, that depends on how you get Internet access, your service provider will generally tell you what you need to get an Ethernet connection in your house (if you don't already have it)
