53 dbmv does NOT neccessarilly mean there is a high noise level, it simply is a
measure of the carrier output level the modem is using to 'talk' back to the
cable company hardware. Noise is only one possible reason, a more common reason
is LOSS in the line
& splitters between your modem and the corrisponding cable company modem, this
is typically due to improper/defective splitters, poor connections, excessive
cable lengths, wrong cable type, water/moisture in the cable system, etc.
Half the problem is the suppossed cable tech's don't understand the term's
themselves and or how the signal levels are affected by the cable system, and
to top it off lot's of tech's can't explain this stuff either and they just
throw around some of the
jargon to impress the users, nothing like having to BS your customers and
getting paid for it.
To round this out, there are of course some good tech's in most cable
companies, their the one's that get called out about the 10th time you complain
about it not working.
