The Linksys MX4200SF-UK for Swish fibre™ ISP WiFi 6 Whole Home Mesh System will automatically update when the firmware is available. Manual updates are not supported since firmware updates are provided directly by Swish fibre.

However, you can check if there is new firmware available and/or check what the current firmware version of your node is. This article will help you check the firmware version of your node.

Before you proceed, make sure to have the latest version of the Linksys app installed on your device. You can download it from the App Store® or Google Play™.
