The DRW violations are the least of your worries. You have major ingress on the 900 MHz ISM band (902 - 927 MHz) and moderate ingress on the lower band (300 - 450 MHz) as shown by the number of uncorrectable codewords on those channels.

If you've replaced your interior coax with brand new high quality RG6 then the problem lies outside of your home and maybe off of your property. Only a Cox technician can identify and fix that type of problem.
