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.

Downstream QAM256 are between 8.1dBmV and 15.8dBmV with SNR/MER at 40.7 to 41.4 dB.
Upstream SC-QAM are at 36.0 dBmV.

Downstream is a little high and upstream is a little low but nothing really worrisome. How are the logs?

      Are you in CT too? Also, OP issue is related to problems with upstream OFDM channel. Do you have upstream OFDM channel?
