Here's the result of the ifconfig -m ne2

ne2: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	media: Ethernet 10baseT full-duplex (10base2)
	supported Ethernet media:
		media 10base2
		media 10baseT mediaopt full-duplex
		media 10baseT
		media autoselect
	inet 10.0.0.1 netmask 0xff000000 broadcast 10.255.255.255

As you can see the media is set to full duplex. However the observable
performance of the card is half the fully available bandwidth of the network
and half what NT can do.
	The card is connected as 10base-T to a hub.

		Please help,

	The `SIMPLEX' flag has nothing to do with full-duplex mode.

	Assuming the card is PCI with the ability to switch to full-duplex
on the
	fly, an `ifconfig -m ne2' should reveal the available media types
and media
	options which can be passed to ifconfig's `media' and `mediaopt'
options.
