What are good signal levels?

I have the 75/10 unlimited internet package and I was wondering what is a good signal level range for both downstream and upstream for the CODA 4582U modem?

Re: What are good signal levels?

Hey @Neon_Turtle,

 

Welcome to the community! 😊

 

 

That's a very good question there! A good Downstream Signal strength should be between -10 & +10 which is the case here. For a good Downstream Signal noise ratio, it has to be equal or higher than 25.

 

If the Downstream Signal strength is close to 0, it's very good! 

The Upstream Overview should not exceed 51.
