The telephone line in the upstairs of my house has developed a loud
regular ticking noise that is an inconvenience when using the phone but
stops the computer dialing up the internet. The downstairs is ok so I
obviously suspect the junction that splits the line to the upstairs and
downstairs but I can't see how a dodgey conncetion should produce such
a fault.
I have switched broadband filters around in case they were faulty but
to no avail.
There does seem to be something wrong with the broadband as the
connection details were deleted from the computer soem time last night
when my son was using the computer and now I can't reconnect so is it
possible that the modem has a fault and is making this noise?
