I already have the white-listed bios, I tried two different wireless cards and neither works. I'm not sure of the exact models but one was pulled from a Macbook Pro, the other was from a Mac Pro

Is it possible to put a full sized wireless card in the slot where the WWAN card goes in a T420? I've searched and the only thing I could find was for SSDs. I flashed my bios to get rid of the white-list and the OS doesn't seem to recognize it.
