I came home a little early and decided to poke around inside the router's setup and configuration before I boxed the thing up and tried to do an exchange at MicroCenter.  In going through the setup, I noticed that there was a little checkbox that said I could either use a router's mac address, my computer's mac address, or a specific MAC address (on the internet side of the router).....

Ah.. You shouldn't have to spoof your MAC address.  This situation can
typically be solved by doing a full reboot of the cable modem (unplug
for 10 seconds) any time you change the device on the Lan side.  It will
usually cache the MAC address it finds when it boots up and give you all
kinds of issues it you change devices without a full reboot each time.

You will usually also find that you'll get a new IP address assigned
with each device/MAC change.
