I suspect not. if there was a way to make an Atheros "look" like an Intel, that would be great, but I suspect not (and I'd have to modify the Atheros driver to recognize the "Intel" wireless card as an Atheros.) I am now leaning toward looking for an Intel Centrino NIC as it should be one that Lenovo will accept. At least in the past, they have not sold cards with non-standard IDs, so any card that is one they sell should work. that means Intel Wireless-N 1000, 6205, or 6300. I have no idea if any of these is supported by any current driver, though. Can anyone confirm that any of these three cards will work or an way to find out what PCI IDs the BIOS will accept? Thanks, Adrian, imp, jhb and all the others who have made suggestions. -- R.
