What happens on B to C?
This needs to be tested, to help identify the issue.
Also...how new is the connection at C?
If it is a new install, I would be on the horn with your Frame vendor, to
verify the integrity of the local loop. I have seen this several times,
where under virtually no load, the connection will test clean, but once the
connection is under stress, they will blow packets, big time! I even got to
expericence that personally here at the house with my DSL connection.
