This is a gigabit-compatible switching hub. I've used it for several years, but I'm getting rid of it because I'm replacing my equipment. I was using it until just the other day. The original box, the main unit, the power adapter, and the instruction manual are all included. Please see the link below for detailed specifications. https://www.tp-link.com/jp/home-networking/soho-switch/tl-sg108/#specifications
