Connecting devices to a Linksys router using an Ethernet cable

An Ethernet cable is the most common type of network cable used on a wired network whether at home or in any other business establishment.  This cable connects wired devices together to the local network for file sharing and Internet access.

Linksys routers use Ethernet cables to connect to the modem via its Internet or WAN port and get Internet access for wired and wireless devices connected behind the router.  They also feature four (4) Ethernet ports that you can use to directly connect your wired devices and extend your home network.


While connecting Ethernet cables to and from the router seems an easy thing to do, there are important things that you need to check to ensure that the network connection passing through the router is good and stable.

This article will guide you on how to properly connect your wired devices to your Linksys router using Ethernet cables.

Connecting Ethernet cables

Modem to Router

The Ethernet cable from the broadband modem should go to the router’s Internet or WAN port.


Router to wired devices

The Ethernet cables from your Ethernet-based devices should go to any of the numbered ports at the back of the Linksys router (1, 2, 3 or 4).

NOTE:  In this example, a computer is connected to port number 3.


Modem to Router, Router to Computer

In a home network, the most common Ethernet connection setup is modem to router and router to computers or other networking devices that use Ethernet cables.  A Linksys router only allows four (4) wired devices to directly connect to it.  You can cascade another router or connect a switch if you want to connect more wired devices together via Ethernet connection.


Checking wired connectivity

The LEDs on a Linksys router indicate the activities running on the corresponding ports.  To check the LEDs' behavior, make sure that the Power adapter is plugged in to the router’s Power port and to a power outlet.  To learn more, click here.


Resolving LED issues

If in any case the LEDs on your router do not show any signs of activity, you can do the following:

  • Remove the cables from the router and the Ethernet devices and reconnect them.  Make sure that they snugly fit into the ports.
  • Check that the Ethernet cables you are using are not loose and broken.  If so, get another cable.


  • Check the status of the computer’s Ethernet adapter.  To learn how, click here.
  • Check if your port lights have been disabled.  You can configure this particular setting through the router’s setup page.  To know more about this, click here.

Setting up your router

Properly connecting Ethernet cables to the router is a vital step to successfully install or configure the device.  Once the cables are connected correctly, you can start installing or configuring the router.  Choose from any of the setup links below to proceed:

Enhancing network performance

Wired connection provides faster and more stable network performance compared to wireless.  However an Ethernet cable can only extend to limited distances depending on its specifications.  Instead of limiting yourself to wired technology, you can improve your network and Internet experience by going wireless!  Wireless Fidelity (Wi-Fi) gives you mobile and convenient access to your network.  Aside from routers, Linksys offers a variety of networking solutions designed to give you the best wireless experience.   Some of the most popular Linksys devices are listed below:
