Guys need some advise...

I have a really weird situation..

I am in the process of upgrading my line to 4mbps. Called tm and they said my area can support 4mbps.

So they send the technician over to my house.. he tested and say my line is having big issue

SNR downstream is 6db while upstream is 28db.
Attenuation 44

Max kbps is ~3200kbps only even though the technician said he has opened up to 5mbps for me

at the beginning he said could be my house parallel phone lines or looping issue.. so i called tm next day and have them cut and drag a direct line straight from outside to my modem. (this should guarantee best quality right?) UNFORTUNATELY the issue didn't improve a bit...

my downstream SNR is still 6db only...

any suggestions what i should do ? what could be the potential problem? the exchange side ? i ran out of ideas..

Its from tiang to modem direct thru the back of my window

anyway my issue SOLVED! yay..

asked tm to check and its they PORT issue on their box.. did a reset and something... and my SNR shot up to 30, attenuation 15!

upgraded successfully to 4mbps.
