Internet disconnects for 10-15 seconds several times an hour.

I'm using an Arris SB8200.  For the past week or so, the Internet cuts out for 10-15 seconds several times an hour.  I've run a recurring ping and it shows it dropping on the first hop from my router...

    I would schedule a technician. It might actually take a couple technicians to track down the problem. If it's related to the upstream OFDM channel, that is a very new problem so most Cox employees don't know about it yet. I suggest emailing Cox cox.help@cox.com with your account info and a link to this thread.

Don't post the logs without removing the modem MAC address from it.
