Ok, thanks for your help so far...


I have now adjusted the noise margin slider in DMT to the 2nd from the bottom notch, my router now reads

Downstream
Data rate 3424
Noise margin 9.9
Output power 17.7
Attenuation 56.0

How will I no this is going to be stable now ive altered the noise margin, what do I look for via DMT/router?

thanks
