You'll want to get a "PoE" MoCA filter installed.

• What?
• Why?
• How?

p.s. Add'l references...

• Why every home should have a MoCA filter
• "PoE" MoCA filter installation in a multi-dwelling building
• 'MoCA: Operation and Security Posture' paper

• What performance benefit?
  
• "PoE" vs protective/prophylactic usage

You should be able to call Comcast to get them to send someone out to fix the issue, no charge; and if they fuss, file an FCC complaint.
