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. It's not a Wi-Fi issue--I'm on Ethernet--and it impacts multiple devices. I've power-cycled my cable modem, factory reset it, etc. but still have this issue.
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 firstname.lastname@example.org with your account info and a link to this thread.
