Netgear Modem ADSL/Link issue

[avisachdeva]

[color=rgb(51,51,51);font-family:Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif;font-size:13px;background-color:rgb(250,250,250);]Negear DGN2200 modem+router not working on line with attenuation 45db and SNR margin 25db, ADSL/Link does not get stable. But working absolutely fine with 4 months old connection having fairly good attenuation of 38.5db and SNR margin 22.5 . Is Netgear not suited for my line with these parameters? Should I go for D-Link?[/color]
