Periodic Connection Drops

Having some trouble here. Got a new wireless router Friday as my less than a year old Netgear took a crap. Asus RT-AC68P. However I seem to be getting some connection drops about once an hour across all clients and after a couple minutes it comes back, no reboot needed. At this point I'm not sure if it's a router config issue or a modem issue (everything looks right in the modem). I've tried a different cat6 cable that I know works, but it still seems to be happening.

Here are some screenshots from the modem web panel. I also checked the syslog on my wireless router, but nothing stood out.

Modem is an SB6183. Comcast is my ISP. Please let me know if there is anything else you need, or if this is the wrong sub, I can post elsewhere. Thanks!
