Hi Scott Where are you in the world as i have a spare wireless card that works with the ioxperts drivers. I was using it in a 3400c in the top slot. Never had a problem with it, I just got a mac wireless card given and it seems to get a better signal from my Netgear so i kept using that instead. I could send the other card for you to try if you want? rather than it sat doing nothing. vicki
