Monitor noise on dsl line

Hello Snibborg
  Thanks for the link.  I never knew about this  Very interesting.
Hello nobus:
 You have helped me before.  Thank you for the link.  Very interesting!  So there is relatively inexpensive equipment available to test phone lines.

The problem I experience with CenturyLink or any other technical service is the quality of the people providing the service.  Often they seem to simply follow a script.    When they cannot seem to find an answer they just hang up,  yes, hang up.  Sometimes I can find an intelligent person.  It is so frustrating.   I need an isp for internet service as I don't know how to get internet service without an isp.    Comcast seems little better.

I never know whether CenturyLink is telling me the truth or trying desperately to convince me it's my fault.

What I finally decided to do is to buy a different modem.  My old modem was a PK5000.  I now have a PK5001Z.  I have 30 days to return the modem if it does not solve the problem.  So far (only 2 days) the internet connection is performing well.  I wonder whether there is a firmware update somewhere to apply to the PK5000 that would have solved this problem.

So, for now, let's see if the new modem solves the problem.

Thank you all for prompt replies.  I pay for this service so prompt replies are really appreciated

i hope all goes well...

The problems I've read about REIN and SHINE is that although the main problems are devices in the home transmitting at that frequency, there is a danger that any device in close proximity of the line, between the home and the exchange can also affect the quality of service.  This can include lamp posts, electrical transformers, etc.

Good luck and I hope you get the problem sorted.
