Tracking down some inconsistent latency - likely across Ruckus 510's

[Avery]

*** Revised *** as I had mis-stated part of the issue late last night.

Hello,

I'm hoping someone can point me in the right direction, as I am experiencing some intermittent latency issues.

My current home network is rather simple:
Comcast Cable ISP - Arris SB6190 Cable Modem - Asus RT-AC68W (routing only, radio disabled - Two WAPs: Ruckus R510 Unleashed - Computer and other devices

I have been running some simultaneous pings:
1) Computer to RT-AC68W (192.168.110.1)
2) RT-AC68W to 8.8.8.8

Often I will see intermittent latency only in reaching the AC68W, and not from that router to the public internet, so the issue is primarily inside my network.

Are there any suggestions as to how to track down these intermittent latency issues that appear between client and router? They may come a few times per day to a few times per hour for 2-15 seconds (usually 2-4 seconds).

Note: R510 backhaul is copper, albeit somewhat temporary during construction.
