I am 17K' away from the CO,and can only get 768K DL and had 1.5 before

voice on this line as it is a data line primarily. The OLD 4 wire was
run by the TELCO way back when 60's-70's as a voice line but would like
to increase my DL speed.

1960 style wiring (and things on those phone line you don't know
about) might seriously degrade that ADSL signal. Current requirements
(recommendation) even from the FCC is for Cat3 wire or better.

First, an ADSL modem (better types) provides information about signal
strength. A number to find and record before starting to debug.

Second, disconnect the entire house at that demarc. Connectc ADSL
modem directly to demarc so that your wiring is not used. Then again,
read what those signal strength numbers are. You can 'try this and
try that'. But getting those numbers and doing that simple experiment
will provide far more useful information - and result in more useful
replies.
