what is wan on a router

A WAN port is a port on a router that connects to the modem by an Ethernet cable. WAN stands for Wide Area Network, which is essentially a fancy way of saying the internet. The WAN port is used to connect the router to your internet connection, which is supplied by your ISP through a modem. The LAN ports, on the other hand, are used to connect computers and other devices within a limited area, such as an office or home network. Most routers have at least two ports: one WAN port and one or more LAN ports. The WAN port is usually labeled "WAN" or "Internet," depending on the manufacturer. The LAN ports are used to connect devices that dont have Wi-Fi access. Its important to note that WAN and LAN ports look the same, but they are separated internally with a firewall. This means that devices connected to the WAN port (everyone on the internet) cant access devices connected to the LAN ports.
