      Low downstream noise margin

      Should I be worried by the low noise margin on the router shown in the image or is a low noise margin normal for my speeds?
      Noticed yesterday how low it was and today we have lost connection once, tho the phone line went down at the same time.
      I'm thinking the noise level being so low might cause instability and if so what I can do to get it fixed.

      That all looks fine to me.

      The new DLM software introduced around Easter last year and revised this year around the same time, allows the noise margin to be set much lower now.

      Provided that your line can support the low noise margin, it will stay around that level.

      I would advise against resetting your router too often though as this could trigger DLM to think that there is a major fault and slow you down.
