This guide cuts through the confusion to reveal the distinct superpowers of Internet Backup, Configuration Backup, Replace Main Deco, and Set Main Deco—ensuring you use the right function for the right moment. 

Internet Backup: The "Lifeline" During a Service Outage 

Internet backup is about maintaining continuous operation when your primary service (like fiber or cable) fails. It prevents downtime by continuously monitoring the status of your main fiber or cable internet connection. The moment an outage is detected, the system fails over to a pre-configured mobile hotspot.

Configuration Backup: The "Blueprint" for Hardware Recovery 

Configuration backup is about saving your network's unique settings as a digital file. If your physical router breaks, this "blueprint" allows for a quick setup of a replacement device so that you can quickly restore the previously customized preferences onto a new device.

Replace Main Deco: The "Seamless Hardware Upgrade" 

When you purchase a more powerful and advanced Deco model and wish to use it as the central device in a mesh system without losing the existing network configuration. via "Replace Main Deco", the new main Deco is inheriting the network from its predecessor. 

If you look further, there is one more feature-Set Main Deco, which is often used to troubleshoot whether the main Deco is related to certain issues. It lets you promote one of the working satellite units to be the "New Main Deco" without losing the existing network configurations. So you can quickly isolate whether the problem is with the specific Deco unit.
