Hey Al, Sounds like something on your LAN is suspect, especially if the problem is happening on multiple routers. Were those pings issued from a PC on your LAN or a shell on the router? You'll want to isolate to just the router for now, ideally just your laptop wired into the router.
At the router try running two pings... one to 8.8.8.8 (Google DNS) and one to the public IP address of your cable modem. Do the pings results look similar, dropping or high latency simultaneously? >From your laptop run the same pings plus one to router LAN IP (192.168.1.1 or similar) any issues or variance there? IPv6 shouldn't have an impact here. Name of the game is isolation. Start basic and re-introduce endpoints back in slowly until problem resurfaces.
