And if I set up QoS for gaming, will that affect my other devices plugged in to my switch?

How would I configure the Edge router 4 to be able to plug it in to my switch? Should I use dynamic IP or something else? I just want to make sure I’m getting all the internet speed I can to my switch.

Would I have to set it up something special on the ER4 or just set it up and then plug my switch into the router?
