SNR Margin and Line Attenuation - What do they mean?

[essbebe]

@bimelds
how do i solve this?
Change Mod to GDMT ( if in AUTO mode or ADSL2 +)
Always mention modem/router model/make in all posts.
Post in concerned forum BSNL/AIRTEL/MTNL etc.

Hi, I have a BSNL 512 kbps unlimited connection. The problem is I never get anything above 200 kbps speed. My SNR margin is 11.5-downstream and 29-upstream. I've tried complaining to BSNL several time but that keep taking down my complaint and never do anything. Can anyone of you guys help? I don't want super speed, I just want what I paid for.

i have the same connection (BSNL 512 kbps unlimited)
there is problem in ur wire ... check the wiring ... if u find any open end ... tape them
i recently changed my internal wiring ... here is the result
