Here's my configuration, all connected using Ethernet cables:
(Dell PC, Win10) --- (Netgear Nighthawk EX7000-100NAS Extender/AccessPt) --- (Cable company provided Pace router)

The EX7000-100NAS is set up as a wired access point.

What I want learn how to do for future troubleshooting is to ping the Ex7000, and ping the Pace router separately to see what is working.

From the Dell PC cmd prompt, ipconfig shows default gateway as 192.168.200.1
I can ping 192.168.200.1 and it works.
Am I pinging the EX7000 or the cable company's Pace router?
How do I get the ip address of each unit?

Use your browser to login to 192.168.200.1 and see which device it is. If it's the router, find the DHCP device list and see if you can find the ex7000 in the list

Thank you very much for your tip. I did that and it shows that 192.168.200.1 is the Pace router.

To recap, my configuration is:
(Dell PC, XPS-8900) ----wired---- (EX7000) --- (Cable company provided Pace router)
Laptop Mo-Spin3 >>>wireless>>>>^

(XPS-8900 is wired to EX7000) (Laptop connects wireless to EX7000)

The EX7000 shows up in the list. I would expect that since the EX7000 is wired to the Pace router.

However my Dell PC (XPS-8900) is wired to the EX7000 and not to the Pace router, yet it shows up in the list. I would not have expected that. Similarly, my laptop named "Mo-Spin3" is wireless connected to the EX7000 but it shows up in the list, also unexpected.

I can click on "Device Details" for the XPS-8900, EX7000, and Mo-Spin3 and get the IP address for each of them as follows:
... XPS-8900 = 192.168.200.129
... EX7000 .. = 192.168.200.72
... Mo-Spin3 = 192.168.200.73

Using my Dell XPS-8900 PC, if I ping .129 or .72, I get responses. If I ping .73 I get "Destination host unreachable".
Using my laptop Mo-Spin3, I can ping all three IP addresses and get replies.

Why can't my XPS-8900 PC ping my laptop (Mo-Spin3), but my laptop can ping the XPS-8900?

Sorry for the noob questions but I'm trying to understand how to ping for future troubleshooting.
Thanks!

It's running as expected. The ex7000 is a layer 2 device, and likely doesn't have things like DHCP server, dns service, and not a SOHO router.

Sounds like the mo-spin3 is set to discard incoming pings

OK. Not being able to ping mo-spin3 (laptop) from the Dell XPS-8900 is no biggie. I think I have enough info now to troubleshoot future problems using pings.

Thanks for taking the time to help,

No prob, for the laptop, when you have the time/desire, dig through the firewall and see where ping (ICMP) is set to block or allow. Allow it, and test again, if it still fails, disable the firewall. If it still fails, trying a linix live boot media and test some more.
