Eric I tried the other day to force a re-sync using DSLStats but without selecting any option and found that although it says it is doing something actually the router (an HG622) did not re-sync, sure it pauses recording and waits but no re-sync happens. Maybe some mods to that option to perhaps say that the user has not selected anything to be changed and then not do anything, I am assuming (and will check later) that selecting 0db will actually force a re-sync.

PS. Yes selecting 0db and apply does re-sync OK
