I'm currently looking at a relative's Plus net line. Their speeds don't quite seem right.
They are very close to the exchange and their router (Voyager 2110) gives the following info:
Line Rate 9167 Kbps 96 Kbps
Noise Margin 4.9 dB 6.0 dB
Line Attenuation 8.0 dB 0.5 dB
Output Power 0.0 dBm 11.8 dBm
Surely 8dB of attenuation should give 20+Mb/s, and they should certainly be getting more than 96Kb/s of upstream?
But the noise margin doesn't suggest a noisy line (and they've not experienced any audible interference....)
Thoughts? (other than raise a ticket!)
