Hey, so I'm looking for a wireless card that will work with little to no modifications across XP, Ubuntu and OSX. I have a miniPCIe interface. I've done a lot of research on the subject and I'm between choosing a dell 1390, dell 1490, or an Atheros card. Ive heard mixed things about the dell cards in Ubuntu. Some say it requires a little modification to get working. My questions are: is the modification hard, and does the card work well after modification? The atheros cards on the other hand are supposed to work well in all three OS's. My questions about the atheros cards are: Do they require any modifications to get working, and which atheros card would you suggest? Would you suggest any other cards besides the dell and atheros?

Thanks,
Chris
