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.
If your internet disconnects for 10-15 seconds, it sounds like WiFi interference. If the modem actually went offline, it would take much longer for it to re-sync. What router are you using, WiFi modem/Pano, or your own?
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?
