SNR all over the place

[coreservers]

Fitted this new router to repalce teh dying and eventually dead netgear. same model but since installing the SNR has been up and down wuite a bit.
before the change my SNR was a steady 6 since last saturday it's been rising steadily to what you see below today

Connection Speed 6146 kbps 1038 kbps
Line Attenuation 36 db 9 db
Noise Margin 15 db 5 db

I have it in the test socket. my throughput has fallen from 7mb to 4.5 now as well
BT tests keep failing!

odd since chaging the router the connection has become unstable

If it's in the test socket then it's either a line fault or a bad router. Check with support.

It's a distinct possibility, they seem to be kicking the tyres a lot recently.
