i once lived in an apartment in an old building where if you turned on the light in the bathroom the dsl would lose sync.
why this would occur i'll never know. (probably old telephone wiring wrapped around old 110v wiring? maybe? or who knows what kind of weird leakage/ground loops may have existed)
