ADSL is not getting stable on my new Netgear DGN2200 Modem+router. Internet is working fine on my other modems on same line. It may be strange to you, but when I short circuit the two wires of main line of broadband, the netgear modem starts working. Once netgear is connected there is no problem at all. My attenuation is high - 45-46db and was going up to 51db at night on my previous modem and SNR margin varies from 16.5 to 31.5. I suspect most probably some interference but they are not ready to change my line. My broadband line is very close to electrical lines which supply electricity to our homes (220Volts lones).
