internet unstable

[faseman7]

Hi, i have a Netgear DGN2000 router with BT isp and ADSL. I normally have 7mb download and 0.34mb upload. It is unstable most of the time. Can someone please check my stats to see if my noise margin is what it should be as i have heard that snr can cause this problem. Thanks Lee ( not einstein with computers )

ADSL Link Downstream Upstream
Connection Speed 8128 kbps 448 kbps
Line Attenuation 6.0 db 4.0 db

i have only one phone plugged in with a filter and no extention. The snr and attenuation stay the same.
