The switch needs to be connected to the WAN port

The switch needs to be connected to the WAN port

You do not need to connect a switch to a WAN port; instead, connect it to a LAN port for proper network functionality.Understanding WAN and LAN PortsWAN Port: The WAN (Wide Area Network) port on a router is used to connect to the internet via a modem. It serves as the gateway between your local network and the broader internet, allowing devices on your network to access online resources .LAN Port: LAN (Local Area Network) ports are used to connect devices within your local network, such as computers, printers, and switches. Devices connected to LAN ports can communicate with each other and share resources .Connecting a SwitchConnect to LAN Port: When setting up a switch, you should connect it to a LAN port on your router. This allows the switch to expand your local network by providing additional Ethernet ports for connecting more devices .Why Not WAN?: Connecting a switch to a WAN port is unnecessary and would not function as intended. The WAN port is designed for internet connectivity, while the LAN port is meant for local device communication. If you connect a switch to the WAN port, it may lead to network configuration issues and prevent devices from communicating properly .SummaryIn summary, to effectively use a switch in your network, connect it to a LAN port on your router. This setup will allow you to expand your local network and connect multiple devices seamlessly, while the WAN port remains dedicated to your internet connection. By understanding the roles of these ports, you can ensure a stable and efficient network configuration.
