The Mercusys switch is useful for creating or extending a wired network. If the router's ethernet ports are not enough for the wired connections of all your devices, a switch will help. It is unmanaged, ie it does not offer the ability to configure its settings, which makes it even more economical. It is mainly recommended for ordinary users who just want to expand their small, home network and for small businesses without special requirements. It has 5 ethernet ports with a speed of 100Mbps.
