8 different between WAN and LAN port. - Table of contents:
The internet connection that most people have in their homes is what’s called a broadband connection. The router that provides the connection to the internet for your home network likely has multiple ports on the back of it.
Two of those ports are typically labeled “WAN” and “LAN”. That’s WAN port and LAN port.
What is a LAN (Local Area Network)port?
A LAN port, also known as a network port or network connection, is a socket used to connect computers, servers, video game consoles, and other devices to the internet.
They’re typically located on the back of both computers and network devices and are used solely to establish a wired, as opposed to a wireless, internet connection.

What does LAN stand for?
LAN stands for Local Area Network. A LAN is just a collection of devices connected over a short distance, compared to Wide Area Networks (WANs) and Metropolitan Area Networks (MANs), which connect devices located considerable distances from each other.
The term LAN port gets its name from the port’s use in LANs, such as home networks, school, and office building networks.
A LAN port is also known as an Ethernet port. Both terms refer to exactly the same socket on computers, servers, modems, Wi-Fi routers, switches, and other network devices.
The term Ethernet port gets its name from the Ethernet protocol, developed by the Institute of Electrical and Electronics Engineers.
How does a LAN port work?
To connect to the LAN port, you’ll need an Ethernet network cable and two Ethernet-compatible devices.
The Ethernet cable is inserted into the LAN port on the device that is linked to the internet when you need to make a connection.
Connect the cable to the computer using devices such as a router, gaming console, modem, or modem-router combination, and so on.
What is a WAN( Wide Area Network) Port?
A WAN port is a network port that is used to connect a device to a Wide Area Network (WAN). A WAN is a computer network that spans a large geographic area, such as a city, state, or country.
The WAN port on a router is the port that’s connected to the modem. The modem then connects to the internet service provider (ISP).
The WAN port on your router is the one that’s used to connect your router to the internet. The router is in charge of routing traffic between your local network devices and your modem. Each network device can now connect to the internet.
Your router is connected to the modem, that allows access the internet. Your local network devices, such as printers, TV, laptops, android tablet, mobile phones etc, are connected to the router, either wirelessly or wired.
How Does WANs Work?
For instance, a company can have an office in Los Angeles and another one in Texas. While both offices might have LANs that connect the computers and printers in each office, they’ll need a WAN to connect both offices together so they’ll be able to communicate seamlessly.
The WAN will connect the LANs in both offices, allowing the company to share different files and data with everyone.
Wide area networks connect local area networks through the internet. Most businesses use virtual private networks (VPN) to create tunnels that help them encrypt their business traffic and data, making it difficult for those with malicious intent to get access to the data.
The VPNs are configured in all office locations so every information sent over the WAN is private and no unauthorized user will be able to access it.
Difference between LAN ports and WAN ports
| Comparison | LAN Port | WAN Port |
|---|---|---|
| 1. Meaning | LAN port creates the local network by connecting all the devices via ethernet cable or Wi-Fi. | WAN port creates a wide network by connecting all the routers via cable. |
| 2. Full Form | Local Area Network Port. | Wide Area Network Port. |
| 3. Use | LAN port is used to provide Internet access or files sharing facility to all the connected devices. | WAN port is used to provide Internet access by connecting with a modem or wireless broadband to all the connected routers. |
| 4. Speed | LAN ports have higher bandwidth up to 1000 Mbps. | WAN ports have Lower bandwidth than LAN ports up to 100 Mbps. |
| 5. Number of Ports | There are many LAN ports that can be seen on the router, it can be 4, 6, 8, etc. | Most often, there is only one WAN port on the router. |
| 6. Color of Ports | The LAN port usually comes in yellow color. | Most often, there is only one WAN port on the router. |
| 7. Networking Devices | Wi-Fi, Ethernet Cables, Token Ring and Fiber Distributed Data Interface, FDDI, TCP/IP, etc. | Optical wires, modems, routers, switches, bridges, wireless broadband, and Satellite. |
| 8. Data transfer Protocols | Ethernet cable and IEEE 802.11. | PPP, HDLC, and Frame Relay Protocol. |
The LAN ports on the modem are intended for connecting to a local network, but they can always be made WAN, in the modem settings, if necessary.
You might need some professional assistance depending on the device you have, and the service type that your provider executes.
LAN only allows direct topology, while WAN is based on mixed hierarchical topology.
