    I don't know what has gone wrong with my connection. I have 4mbps plan and I was getting the speed up to 3.6 mbps (speedtest.net) initially for three to four days. Then suddenly the speed dropped to about 1mbps. Under my plan I have 4mbps speed up to 20 gb, a limit which I have not yet crossed. I don't make much of the ADSL statistics, but some better brains may surely be able to tell me whether my line is ok.
    To add: earlier the latency factor (ping) was low, about 25 ms and now it's showing above 150ms.

BSNL guy explains me that whenever your plan speed doubles, it will make your SNR value half. As well as SNR also depend upon distance and my place is almost 4KM from exchange.

    Solution for this is Optical fibre cable which may they launch in this year ending. Any comment guys!
    @meetdilip ~ Please reply for the above too

    Your SNR is too low and Attenuation is too high. I really wonder how you get such good speed. I am hearing the SNR will half with the double speed theory for the first time. Get your line checked. Make sure there are no joints or non insulated /oxidised parts. Ask the line man to give a clean line. The speed you are getting is good and no problem with the port at exchange.

    Nothing wrong with the stats. Better complain to the SDE. Talk to him and seek help. This may be of some use

    snr seeems ok. 33.6 dB
    check the distance theory with. attn d/l +default cable loss13.8
    Attainable speed possible seems ok.

    @meetdilip ~ As JE said, They have provided me the best Pair/port and Line is absolutely fine and SNR is idle for upto 4Km distance i.e. 2.8db (Downstream). I also wonder that my SNR values are low and still i am getting 3.4Mbps speed. What can be the reason behind this?

    @essbebe ~ My SNR values are 2.8db(Downstream) and 23.4db(Upstream) but you have mentioned 33.6db. May i know which statistics you are reading?

    Sorry. my mistake quoted from another user's attachment Post no 21.

    you can Uncheck box ADSL2+ in DSL menu
    and recheck SNR
    Mention your modem model. Ut300r2u?Firmware version ?
    Attach Device info page screenshot.

    @essbebe ~ Please check the screenshot after disabling ADSL2+. Only little improvement can be seen from 2.8db to 6.9db.
    I am using BSNL DNA-A211-I Modem, please check the attachment for more details. And give me the reason accordingly. Thanks!

    This is a great improvement . a 3 dB gain!
    The Sync speed is not improving.
    Your firmware version is also old
    FW update details if needed.
    . at your own risk !

    If you are satisfied with the performance do nothing now.
    ( stable connection good speed )
    For record: check speed here and post the image.
