Noise Margin

Hi,
    My connection speed is always fairly  steady at 5600 Kbps. My download speed has varied over the last couple of years from about  1800 Kbps to a heady 4300 Kbps. It's about 3600 Kbps at the moment and it's useable.
    For the last few weeks my noise margin seems to go haywire over night. My router hangs on to the connection no matter how low the noise margin goes and the connection speed stays solid at at 5600 Kbps throughout the period.  Browsing slows down a bit during this time though there doesn't appear to be that many CRC errors.
    Curious to know what causes this kind of behaviour.
      I've attached a 24 hour plot of the noise margin and this is about the same every night.
Regards

Re: Noise Margin

HI isomer,
Could be many things; street lights interfering perhaps?
