@PavelV  The dashboard internet capacity is a static measure that is set up to take a snapshot every so many hours based upon how you have it set up.  Its not live.  The gateway percentage is a near realtime display of how much of your total capacity you are using at that particular time.  How do you have your internet speed test  settings configured?  If you go under settings->site, you can set that between 10-999 hours.  I have mine set to 24 hours.  

I can then pull the history and see if my speedtests are showing any sort of degradation.  But if you have a good internet connection....that internet capacity display should always be the same or maybe +/- a few megs either way of your rated capacity.

Hello,

my "Speed Test Interval" is setting to 12 hours. Even if the speed test in the graph changes, the internet capacity is still the same. It does not change depending on the measured speed.
