When to avoid using a WAN port?

  • To begin with, you should always keep in mind never to connect another router to your same network or the WAN port. This might bring a lot of problems while using the internet on your devices. 
  • For example- when you share the same piece of fruit with someone, your share of the fruit reduces. When you connect your secondary router with the WAN port then, your secondary router will be excluded from the LAN that is the local area network. This means that you will not have to use multiple routers for a particular office or home as it will not be the best idea.
  • The best way is to connect all the devices through the local area network and then, connect your primary router with the wide-area network port so to connect all these devices with the wider network.

 Always remember that if you wish to connect your local device then, you need to use LAN instead of WAN for every device. The primary router may be connecting to the WAN but all the other devices at your place have to be connected through a local area network. Now, let us move forwards to understand why it is crucial to have routers for the WAN connections.

  • The routers play a very significant role as without the routers, you will not be able to enjoy using the internet connection. Routers are the medium to transmit the internet connection from the WAN port to your devices. 
  • Alongside, the router is also burdened up with the responsibility of redirecting the package requested by a particular device after identifying it.
