I have a long-standing fault (many line drops) not cleared up after two site visits in which all local joints have been re-terminated. Before reporting it a third time, probably as a landline fault, can someone answer a question?
While the fault condition persists, the line reconnects at lower speeds. Downstream speed (as indicated by the HomeHub 5) is cut to about 80% of normal but Upstream can go down as low as 5% of normal speed. Does this mean the noise originates at the exchange or cabinet end, where upstream signal is at its weakest?
