    It seems not - duplex setting is provided/handled by the 3rd party NIC driver and not the WMI service.

    Have a look at the properties of your network card. If you are using a fixed LAN and not a wireless card you should have some options. Most PCs are set up as auto as default, so the speed and duplex are taken from the device that you are hooked up to.

    It's all very well having a GigabitEthernet LAN port (for example) but if you only have a 128 kbps connection guess what your data rate will be?
