I didn't know you had multiple 3com cards so I didn't mention this earlier, but you will find the 3com cards with the WHITE label on the card to work better than the ones with the YELLOW label. It's a chipset revision thing. It also happens under some versions of Linux. The underrun error is perfectly fine and can be ignored. I have gotten them myself with no ill effects. You will not be able to fix this message. It will go away once the driver has increased the buffer enough. Ted
