Thanks for the hints, Mark.  Here's what I found...

Wireless has no "physical" switch, but something I think is pretty 
much the same.  There's a lighted button above the keyboard which, I 
think, is interpreted directly by the bios.  It shows "off", and does 
change when pressed.  It is set off, which I suppose means that the 
radio is off.

The system does show both eth0 and wlan0, both as options during the 
net-install, and also in the "ifconfig" response.

Strangely, when I tried the install again just now, and selected 
"Desktop" (instead of "Minimal Desktop" as I did last time), all 
worked properly.  Ethernet works.  Perhaps the problem is that 
"minimal desktop" didn't include the ethernet drivers?

I guess I withdraw my complaint.

David
