Upstream Modulation

[paul1276]

I understand the Modulation figure should be 64QAM

Is this something that should be looked at?
Thank you.

Whilst less than 4 x 64 QAM can be a sign of problems, the upstream has plenty of headroom, so if it is consistent at 4 x 32 QAM then that could be fine.  The normal way of judging is if you're experiencing connection problems.

Thanks, no obvious problems but just checking.
