Hi, 

Deco App displays the real-time speed rate of the device in the local network. It is quite different from the network speed.

For more details, please refer to How to Understand Speed Rates on the Deco APP

"But whenever I'm downloading something it's much slower( I tried downloading test packages)"

-Did you use "Download Test Files"? How about the test result of downloading test packages?

The variation in Ookla Speedtest results compared to your actual download speeds can be influenced by multiple factors, such as the server's capacity, network congestion, and the source of your download. Ookla tests focus on your connection to a particular server, whereas your download speed can be impacted by both the server you are downloading from and the path through which your data travels to reach you.

Thank you very much.

Best regards.
