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
