   Stick with the SMC. The performance limit you are seeing is caused by your
Neptune-based motherboard, not by the card. The Intel EE Pro/100B does achieve
about 5% higher rates, but a bug in the NIC that causes the receiver to stop
receiving when a minor glitch on the network happens is too annoying (you
have to manually reset the card to get it going again). This is supposed to be
fixed in the next rev of the chip.
