WAN (Wide Area Network) refers to a large-scale network, that is, a network across regions, cities and countries on a global scale. Multinational companies with offices all over the world communicate with each other in many ways.

WAN port is used for connection, such as an Internet line given to you by ADSL, or a line that gives you access to the Internet after the optical fiber is connected.

This router has dual WAN ports, which means that it can connect two ADSL lines at the same time and use two ADSL accounts.

When connected, lights W 1 and W2 will light up.

100M is the bandwidth rate of this interface, and it is 100M port.

LINK/ACT indicates that the port can be activated through link.

S- and L- may mean speed and link, that is, speed and link.

That is to say, the port is at the rate of 100M, and is in an active and available state.

LAN refers to local area network, which is a small area network, namely internal network and local network.

LAN ports are usually connected to computers and other devices.

The console port is generally the control port of the device, which realizes the initialization or remote control of the device. The console port is directly connected to the serial port of the computer with a dedicated connection, and the router is configured locally with a terminal emulator (such as HyperTerminal under Windows). The console ports of routers are mostly RJ-45 ports.
