Hi
I apologize for the trouble you are having with our service. intermittent outage like these are most often caused by a loose connection or damage to a line a wire near your home. I recommend checking the coax cable that leads from the wall to your modem and cable boxes if they are also wired. If the problem continues please contact us privately so we can check on this, and help get a tech visit schedule if needed. Our email address is cox.help@cox.com Please be sure to include your name full street address and a link to your forum post.
