The Mercusys switch is useful for creating or expanding a wired network. If the ethernet ports on your router are not enough for the wired connections of all your devices, a switch will help you. It is unmanaged, meaning it does not offer the ability to configure its settings, which also makes it more affordable. It is mainly recommended for simple users who just want to extend their small home network and for small businesses without special requirements. It has 5 ethernet ports with a maximum speed of 100Mbps.
