    Hi,
    same problem. I was talking to my ISP about something else and mentioned this was happening, so they tweaked my service, but no improvement.

    Usually means you are receiving hits (noise or similar) spikes on your adsl service. Too many will cause you service to dropout.

    I know when we have a lot of rain, my service suffers, but not usually for a period of a week or so. I don't have any history at the moment, I have just completed a fresh installation so I can't track back.
