What does DS mean on the cable modem and why does it glow in orange?

Hello in recent times I noticed a clear drop in internet speed from 60-70Mb to 5-30Mb I do not know what is the modem is Arris tm822 noticed that it is slower when the LED diode on the modem shines as the only orange, and not like the other green. If, however, it shines green with the rest, the internet is as it should be. How do you think to call someone from multimedia or bury something yourself? In total, the cable that provides the internet is unstable but it does not explain the speed because even if it is fully inserted it can also net. What is going on? ^^

DS means Downstream.

The orange LED means that the modem does not work on all carriers in this direction - the problem is to the operator.

What does unstable cable mean?
This can be the potential cause of problems.

This is probably the most sensible answer in this topic.
