Not sure how it works nowadays, but back in the T60 days at least, the wireless cards used in those Thinkpads was part of those things you could choose (tho you often didn't really know was at stake because the descriptions were not precise enough), so if that's still the case, there's no guarantee that your T540p has the same wireless card as all other T540p.
