Differences between WAN and LAN ports in routers

Currently, many households have installed home broadband. Although broadband operators are different, one of the almost essential devices for installing broadband is a Wireless Router. For China Telecom, China Unicom, and China Mobile, the three major operators have basically achieved fiber optic cable entry and achieved photoelectric conversion through optical cats. Most of the equipped optical cats come with wireless router functions. The customized optical cat configuration by operators is relatively low. Although it comes with built-in wireless functions, the antenna is built-in and the signal is weak, which is not ideal for home coverage. Therefore, it is essential for users to provide their own wireless router. 4G Outdoor CPE

Upon closer observation, you will find that a typical wireless router has one WAN port and four LAN ports (the color of the WAN port and LAN port is generally different). For high-end wireless routers or enterprise routers, the number of WAN and LAN ports may vary. For third-party firmware, the number of WAN and LAN ports can be set and adjusted in the router, and LAN ports can be used as WAN ports (this article will not elaborate on this). The following figure shows one of the common wireless router network port layouts and quantities. 5G Outdoor Cpe

Precautions during use: WAN ports are generally used to connect to external networks or higher-level networks, such as optical cats or higher-level routers. They cannot be used to connect to computers or set up wireless routers. The LAN port of a wireless router is generally used to connect computers or other devices that require internet access, such as smart TVs, network printers, or WAN ports of lower level routers. All devices connected to the LAN port are located within a local area network, and devices can access each other. 4G Outdoor Cpe

The above is a detailed explanation of the differences between the WAN and LAN ports of wireless routers, as well as precautions during use.
