Hi, I have been looking at my router stats lately which are:

Downstream Upstream
Connection Speed : 7808 kbps 448 kbps
Line Attenuation: 37 db 10.5 db
Noise Margin: 6 db 25 db

since i never seem to be downloading at over 4mb, except early in the mroning (4-5am). On further investigation i believe this to be my ISP throttling (eclipse who use Tiscali :( )

However, i noticed i have a very low downstream noise margin 6 db. Which i am concerned about. After a bit of research i have learned this could cause frequent disconnects and other problems. At the moment I am usign a Netgear Dg834GT Router and have zero disconnects. But, i am thinking of getting a wireless router soon when i move to BE and do not want my low noise margin to be a problem.

I had ADSL fitted soon after it was released and had a BT engineer come round and install it.
He fitted a proper faceplate and wired it up in the living room (the master socket is in the hallway near the door).

I have tried the following in order to increase my Noise Margin:

Already using proper face socket
Tried plugging router directly into the facesocket instead of the extension - this made zero difference.
Tried rebooting router several times to see if my sync rate would decrease and noise margin increase - it did not change. Sometimes I might sync as low as 6900 but my noise margin again does not change and I merely believe this to be the time of day (i.e. how busy the ISP is) as to what i Sync at.

Is there any other way I can improve my Noise margin. The reason being 2 days ago in the bad weather I had a disconnect (extremly rare) which never happens unless there is soemthing wrong with my ISP. And when I checked my stats my Nosie margin was 3 db :( So obviously it was affected by the bad weather.
