Modem is constantly resetting

About 3 months ago our internet started to randomly drop out. I call Comcast to no avail. So I replaced my modem to an Arris Surfboard SB6190, replaced the router to a Netgear R6260. There are no splitters. Just a straight coaxial cable into the modem itself. 

 

Here are my stats from the modem. I think my upstream power level is way too high. Not sure what to do about this.

 

Upstream Bonded Channels
Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power
1 Locked ATDMA 65 5120 kSym/s 35.80 MHz 57.00 dBmV

Re: Modem is constantly resetting

All of the levels posted are bad and out of spec. If you’re sure you have no splitters, you may need a tech out to troubleshoot further.
