What would I read to learn about this? About how this is done?
Either I'm only partially getting this or I know something that ain't
so. If a device comes out of the box with a MAC address printed on
it, I infer that it's coded in the hardware. As well, I infer from
/etc/rc.d/rc.wireless.conf that some bits of the MAC address identify
the mfgr/vendor which in turn implies a hard-coded value. Do you mean
by "assign any MAC", creating a virtual or spoofed MAC address known
to the OS and mapped by the OS onto the "real", hard-coded MAC? I
don't quite see how that would work.

No. D-Link DI-713P (DL-713P?) from a junk bin. Has 3 ethernet ports,
WAN port, "com" port, printer port and antennae. And there's no
cable connection, not a cable router, I'm too far off the beaten path
to have cable. I do dialup via an external modem connected to a
desktop computer, not via the router. The router just makes it
possible to move stuff between 3 boxen in the house and 1 in the shop.
Well, I think my question is answered, regardless of the matter of
changing a MAC. Separate functions/modalities of the router have
separate hardware devices and thus separate MAC addresses.
