Re: [OT] Help with SNR on BT line

["Erik Carlson" <erik@xxxxxxxxxx>]

Craig, do you by any chance have an unfiltered sky box on the line.
Such boxes often call home at night, causing line noise and lost
synch.

Otherwise I would look for events that only happen at night, perhaps
you have economy seven with night storage heaters?

Low voltage lighting is also notorious at causing noise on just the
right frequencies to upset  adsl. perhaps you have a nightlight, or
your building has communcal lighting which goes on at night?
