Which RG do you have?, any changes inside home?

Basically you downstrem SN margin is at 6.0, anything below 9 down is trouble
Higher SN number better connection to provide service...
Your upsteam is very good...if the two sides were swtched probably be happier.

As signal to noise margin is always changing ...a relationship to signal strength provded versus surrounding noise.
Many things can affect this this relationship...both uverse controlled and non controlled.
