Assuming those statistics were obtained a.s.a.p. after the modem/router was powered up, then we can safely deduce that the target SNRM is set at 9 dB.

If its a line issue watch your snr ring the circuit and look for a wobble or crc errors if no change or errors, exchange equipment would be my bet.

Ok after talking with my ISP aparently the issue is the quality of my line currently its degrading every few days can anyone advice what i can do now as my ISP have said to speak to BT or wait for fiver i had one of the managers go over the reports from BT openreach and aparently its something with the line from the cabinet outside to the exchange. This last week ive been getting some SNR spikes upto 100db what caused the connection to drop once to give you an idea what my stats are like now ive added them below (restarted the router not long ago).

I realy need some advice on what i can do to get my line fixed
