since I added phone and contour to my existing TV and Internet my mini boxes don't work.
I have been with tech support 6 time in the last week and they all said once we hook up the contour that the account would miraculously begin working. I knew it was bilge water when they said it but...
Mini boxes will work in the same household as Contour. Are you getting an error message or error number on the mini boxes? Are you able to run the channel scan on each mini box? (Refer to https://www.cox.com/residential/support/running-a-channel-scan-on-a-mini-box--dta.html.)
It sounds like you might benefit from a service call at this point. My team can set up a service call at a time convenient for you. Email us at firstname.lastname@example.org and include your full name, address, and a link to this page. We'll get those mini boxes working correctly for you!
