Linksys periodically releases new firmware for its device to allow users to fix a network, add new features, and upgrade the existing ones. Your Linksys router automatically searches for an available firmware for your device and if there is a new firmware available for your device, it notifies you through the notification on the linksyssmartwifi.com page. In some cases, you need to check for a new firmware through the “Check for updates” option of the Firmware update page.
