Upload horrible

Download is fine but upload ranges from  .8 to 1mpbs.   Signals look good.  Could it be noise in the line or a node conjestion problem?     I have preferred 250/10.  More uncorrectables on the higher frequencies that are more sensitive.

EDIT

It is noise.  MER SNR is down to 35 on some channels
