That was it.  Sorry, I plain didn't see that, and being used to configuring
the gw in with /sbin/route, I naturally looked at the routes tab (and of
course, it does have a gateway).

So, adding in the gateway to the address worked, I'm good.
Thank you for that.

That certainly seems to the case here.  Disconnecting the ethernet caused it
to revert to wlan, and with the gateway likewise configured there, it did The
Right Thing.

Thanks again for the assist,
