I moved to new house and I have VDSL service exactly like the one I have before but I'm having issues with speed dropping, sometimes I get full speed which is 20 Mbps and sometimes I get 2 Mbps, so I looked into the connection details in the router and compare them to my old connection details and I found downstream noise safety coefficient is much higher than before.
DSL synchronization status:Up
Connection status:Showtime
Upstream line rate (kbit/s): 1119
Downstream line rate (kbit/s):22527
Maximum upstream rate (kbit/s):21517
Maximum downstream rate (kbit/s):144608
Upstream noise safety coefficient (dB):38.2
Downstream noise safety coefficient (dB):39.1
Upstream interleave depth:15
Downstream interleave depth:545
Line standard:VDSL
Upstream line attenuation (dB):0.3
Downstream line attenuation (dB):4.3
Upstream output power (dBm):-8.3
Downstream output power (dBm):10.7
Channel type:Interleaved
So when to consider the noise safety coefficient as bad one or good one ?
