WiFi is a bit trickier to upgrade on the older Thinkpads. A lot of them will not boot unless the card is whitelisted in the bios. If that's the case, then you will have to flash a modified bios.
Oh, right! I have flashing the bios on my w520 as a pending project, and had forgotten how deep in the rabbit hole some upgrades and mods are.
