Ethernet generally provides better performance and less latency than Wi-Fi, but often the ports found on the back of your router are not enough. This is where a network switch can be used to expand the number of ports available.
Many people are used to simply plugging their router in and immediately connecting to the Internet. This can certainly work, but you may be missing out on optimizing your Internet connectivity and speeds.
If you have a large home or even just a large home network with lots of devices, adding a second router can not only better coverage both wired and wirelessly, but also improve overall performance.
