Key notes

Youhave a wireless routerand a curious mind as you want to know the differences between the LAN and WAN ports that your router has.

If you are thinking about it and have landed here, then you will get all of your answers and more importantly, what are the differences between WAN and LAN and when to use each one. Let us get right into this comprehensive guide.

WAN Port vs LAN Port

So, without wasting much time, we are jumping straight into the comparison. This table will help you understand what basically is a WAN and a LAN and what differentiates them from one another:

WAN vs LAN on a router

As we have already mentioned in the comparison table above, a modem will have typically one WAN port and multiple LAN ports.

The WAN port on a router can be used to connect to a high-speed modem, which then connects the router to the internet. You will find the WAN port on your router labeled WAN or Internet.

On the other hand, the LAN port is used to connect computers thatdon’t have Wi-Fi access. It can connect to the LAN port viaan ethernet cableand then establish a connection with the internet.

The moment the cable is plugged into the router, you have established a wired connection.

LAN vs MAN vs WAN

Apart from LAN and WAN, there is MAN as well. In such a case, it becomes important to know the difference between them as it will help you make a decision on when to use one.

Should I use a WAN or LAN port?

For those who wish to connect to the internet, then you should use the WAN port and connect your router to it. Because LAN will let you connect two or more computers together and transfer data.

The WAN port on your ISP router is the one that brings the internet into the network. Using the WAN port to connect to the second router won’t give you internet access.

In this case, you can make use of the LAN port and connect the second router via the LAN port and then enjoy internet access with the second router.

Also, you should not confuse WAN with a Wireless Area Network. WAN stands for Wide Area Network, whereas, WLAN stands for Wireless Local Area Network. WLAN is a LAN with wireless functions instead of an ethernet cable. So, when you connect your device to a router using Wi-Fi, you are using WLAN.

When is it best to use LAN, WAN, MAN, and CAN?

Here are some of the best use-case scenarios for LAN, WAN, MAN, and CAN.

When should I use the WAN port on the router?

If you have amodem and routeras separate devices then you need to connect them in order to access the internet. The connection is done via an ethernet cable. Through this connection, your modem passes an internet signal to your router, ultimately which allows you to access the internet.

So, if your router isn’t connected to the modem via the WAN port, you won’t be able to access the internet.

Is LAN or WAN better for Ethernet?

LANs have better speed and reliability as compared to WANs. Typically, LAN speeds range between 1,000 Mb/s to 40,000 Mb/s as compared to 150 Mb/s WAN speed. LANs are also easily manageable and less costly to set up.

That is it from us in this guide. If you are getting lower ethernet speeds, then you can refer to our guide and apply the 10 experttips to enhance the internet speed.
