New Modem

I recently upgraded my modem to an Arris Surfboard SBG7400AC2 and have been experiencing daily drop out for approx 5 minutes multiple times during the day. There is no pattern, it could occur any time. I think when the new modem which is a docsis 3.0 was enabled it may have been put in incorrectly in your system because it reports back on the upstream side as docsis 2.0 (there should also be 8 upstream sessions and it's only reporting back 4) please see below
