Thank you. Those test results should be useful for isolating and
debugging the issue.
HTH, but would it help isolate the problem to temporarily put
nameserver 192.168.1.254 back in resolv.conf and retry the above?
AIUI, no. See Greg Wooledge's reply for an explanation.
BTW, I just saw your earlier (revised?) post about using Windows on the
laptop. Yikes! If you don't mind, I'd like to skip that. Besides, my > local network is much simpler since there is only one ethernet
connection. Sorry if I misled you.

Connecting the Debian computer to the AT&T gateway and connecting the
laptop to the gateway is a simpler network (star topology) than
connecting Debian to the gateway, configuring Debian as a Wi-Fi router,
and connecting the laptop to Debian (router-behind-router topology).
Interactive desktop usage and network routing are two functions that are
best fulfilled by two separate devices. While one device can do both,
complexity and risk are greater in one device than their sums with two
devices.
It is possible that your name resolution issues are due to some
misconfiguration of Debian in its networking role. Please document how
you have installed and configured Debian -- ISO, tasksel, packages,
Ethernet interface, Wi-Fi interface, routing, address and/or port
translation, firewall, DHCP proxy/ forwarding, DNS proxy/ forwarding, etc..
