I have noticed that there is virtually no packet noise on my connection between 6pm and 8am. While, at the same time, packet loss increases noticeably during the day, particularly between 8am and 2pm. This seems to be at odds with the fact that my snr decreases slightly in the evenings as opposed to the day time.
Is this a consequence of the fact that environmental noise is a great deal worse in the day time?
(I live in a very noisy built up area, where there is a great deal of environmental noise - building work etc. during the day)
