BSNL ADSL Broadband - Frequent Disconnection.

[deba]

Dear All,

I have a BSNL Broadband 750 Unlimited Plan and using a Huawei MT882 Modem.As per the modem configuration page my Upstream SNR is 18 db and Attenuation is 3db. The downstream SNR is 8.5db and Attenuation 6.5db.

I am getting frequent ADSL disconnection. What is the cause? Are there any line noise as per the SNR and Attenutaion level?

Kindly help.
Thanks.
