I live in a house with multiple people and pay for the fastest internet the local company has.... the router/modem has multiple things connected via WiFi but is well within the limits of what the local company claims the modem/router can handle for connected devices both WiFi and wired. I play my games wired with no issues unless the other person in the house is also playing games . I am trying to figure out why when we are both playing wired simultaneously I experience significant noticeable lag but they do not so I can fix it
