I am encountering significant interference with most channels onboth FIOS boxes. Is it cold weather related? Any suggestions?
Most relevant issue could be loose coax connection.
Especially if your ONT is outside.
Start at ONT and check to make sure that all connections are tight.
I did with no improvement. Also replaced all splitters and indoor cables with no improvement. Problem temporarily improved with 20+ degree temps but returned with single digit temps.
