I always found Angry IP Scanner https://angryip.org
A convenient java based tool to scan the local network. I reports the IP
addresses, Hostname, Mac Address and even MAC Vendor. (as well as other
things, all configurable from a tools menu).
Much quicker than manual pinging. It launches lots of threads (mine is
configured for 100) and gets all results of scanning a /24 net (256
addresses to analyze) in 4 or 5 seconds.
It won't help determining why the router isn't responding, but if it is
responding it might provide data if it suddenly decided to respond to a
different address, other than the presumed static address.

Have you tried power cycling it?
Russell,
Yes. This makes no difference. And I should have written that my friend
connects through this WAP from her laptop daily with no issues. It's
working
as the wireless connection between her laptop and the router/outside
world.
Do you know the MAC address (probably printed on the case)?
There are two:
LANWLAN MAC: 08863B51998A
WAN MAC: 0886B51998C
Check the DHCP leases on your gateway router for that MAC address.
All IP addresses on the LAN are static
Try pinging all the addresses. I assume there are only 253
possibilities,
so that's easy to script.
Cannot ping the MAC addresses from the shell.
Thanks,
Rich
