I am using ULD 850 Combo plan and after using up 8GB @ 2mbps, speed is throttled to 512kbps(as per BSNL). but, I see frequent disconnections almost unusable. There is no noise from the line. I checked DSL modem for some stats. here are the details:SNR Margin : downstream- 10 upstream - 6 ( it goes worst to 6 for downstream)line attenuation - downstream- 48.0 , upstream-74.9line attenuation was always around 40-45 range for the past 8 years with BSNL broadband and worked fine.What should be done with frequent disconnections?
