Setting up the Linksys MX4200 using the web browser

This article will teach you how to set up the Linksys MX4000 Series WiFi 6 System via the page.

Before you begin:

  • You will need to use a desktop browser using your laptop or desktop computer.
  • Write down the default WiFi name and password, and Recovery Key located on the bottom of the parent node.
  • Parent node - A parent node is the Linksys MX4200 connected to your modem.
  • Child node - A child node is another Linksys MX4200 used to extend your WiFi.  The child node can be wireless or wired.


Step 1:  
Make sure that your modem is connected to the internet port on the node.  Power ON the node and wait until the light is solid purple.

Step 2:  
Connect your laptop to the default WiFi name and enter the default WiFi password when prompted.

NOTE:  You can also connect your computer to the node via an ethernet port.

Step 3:  
Open a browser, enter "" in the Address bar, then press [ENTER]

Step 4:  
Click on the mobile image.

Step 5:  
If this is your first time setting up the router, you will need to create a new password.  

The Linksys MX4200 does not have a default admin password.  To create a new password, try one of the following methods:

A.  Enter admin and click on Sign In.  Click on create a new one.  You will be taken to a new screen where you will be prompted to create a new password.

B.  Click on Reset password, enter the Recovery Key found on the product label at the bottom of the router, and click Submit.

Step 6:  
Create a new admin password and an optional password hint, then tap on Reset.

Step 7:  
Once you have created a new password, you will be able to log in to the dashboard.

Step 8:  
Click on the CA link at the bottom right-hand side.

Step 9:  
Click on Connectivity and then click on the CA Router Setup tab.

Step 10:  
Create a WiFi name (SSID) and password and click on Setup Node.  The WiFi password is case-sensitive.  Click Ok or Apply.

While the settings are saving, you will lose WiFi connectivity temporarily.

Step 11:  
The light on top of the parent node will start to flash.  Once you see your new WiFi name on the list, connect to it to continue with the setup. 

You will now see the Your Master Node is now Configured message.
Step 12:  
Now check if your node is online.  If the light on the node is solid blue, it is online.  On the dashboard, the Network Status widget will display if your router is online.

Step 13:  
Do you have additional nodes to add to extend your WiFi?

A.  No - If you don’t have any other child nodes to add, go to the next step.

B.  Yes - Power on your child node, wait until the light is solid purple, then click on Add Wireless Child Nodes.  

Wait for the child node’s light to turn solid blue which may take a few minutes.  Once the child node has a solid blue light, it has been added to the network.  Click on Ok.

For wired nodes, connect your nodes to the parent node with an ethernet cable, wait until the light is solid purple, then click on Add Wired Child Nodes.  When the child nodes show a solid blue light, click Ok.

Your network is now set up.
