Step-by-Step Guide to Replacing Your Old Router

Now that you are prepared, here is a clear, step-by-step process for how to replace WiFi router hardware in a typical home setup.

Step 1: Disconnect the Old Router

  1. Unplug the power cable from your old router.
  2. Disconnect the Ethernet cable that runs from your modem to the router’s WAN or Internet port.
  3. Remove any other connected cables, such as Ethernet lines going to computers or consoles, and note where each one was plugged in.
  4. If your modem and router are separate devices, leave the modem powered on unless your ISP instructs otherwise. If you have a modem-router combo, follow your ISP’s guidance before making changes.

Step 2: Connect the New Router

  1. Place the new router in your chosen location.
  2. Connect one end of an Ethernet cable to your modem and the other end to the new router’s WAN or Internet port.
  3. Reconnect any wired devices to the router’s LAN ports if needed.
  4. Attach the power adapter to the new router and plug it into an outlet.

Step 3: Power On and Check Connections

  1. Turn on the router if it has a power button.
  2. Wait a few minutes for the device to boot up. Indicator lights typically show power, internet connectivity, and WiFi activity.
  3. If the internet light does not turn on, try restarting your modem by unplugging it for 30 seconds and plugging it back in. Then wait for both devices to reconnect.

Step 4: Access the Router Admin Panel

  1. Connect a device to the new router using WiFi (look for the default network name on the router label) or an Ethernet cable.
  2. Open a web browser and enter the router’s setup address, often printed on the device or in the quick start guide.
  3. Log in using the default administrator credentials provided by the manufacturer.
  4. Follow the setup wizard if one appears. This will guide you through basic configuration.

How to Configure Your New Router

Once your new router is online, take a few minutes to configure it properly. Good configuration improves performance, security, and ease of use.
