After testing your internet speed with the big "Test Internet Speed" button in the top left of the Deco app, it displays the upload and download metrics from your router to your selected test server.

I would like to see a latency value displayed as well like how SPEEDTEST does when running on a web client.
It would be useful for debugging latency issues in the mesh network (i.e. Determining if  abnormally high ping is due to poor mesh node placement or if it is ISP side.)
