Why the attenuation is different on my two different make modems? Actiontec gives 0 for both downstream and upstream. I have tried with two other Actiontec modems and they gave the same results. Is Actiontec unable to give the correct value? Or, ZyXEL is incorrect?
ZyXEL Q1000Z:
Levels / Downstream / Upstream
SNR / 21.6 dB / 24.5 dB
Attenuation / 13.0 dB / 6.2 dB
Power / 17.0 dBm / 8.1 dBm
Actiontec C1000A:
Levels / Downstream / Upstream
SNR / 21 dB / 24 dB
Attenuation / O dB / O dB
Power / 17 dBm / 8.1 dBm
