If you're replacing WiFi cards in ThinkPads, check into which cards are supported by the unit - there's a whitelist that varies by each model. I learned the hard way trying to get someone with one of the cheaper models onto 802.11a with a replacement card - the new card was used in other models, but the laptops he had only shipped with one type of card and a correspondingly short whitelist. You can find hacked firmwares to remove the whitelist functionality, but that depends on your willingness to run hacked firmware.

Yes, you need to buy a card that has a FRU code that is whilelisted by Lenovo.

> whitelist Jesus that should be made illegal on laptops. MSI did that with the wireless card. (Won't buy a product from them again) There is no reason that I shouldn't be able to switch out what's in the mini-pci slot.

  Debatable but understandable. They whitelist cards that they tested and certified the laptops with, which may actually be significant / required for some devices. The problem device for me was a ThinkPad Edge something, I believe the lists for the better systems are significantly larger. Still annoying though.

    If they don't support the 3rd party card you put in there: Who cares? I'm not going to expect them to support the wireless functionality if I subsitute out the wireless card. What do they need to whitelist cards for?

  ThinkPads traditionally wound up in specifications for sophisticated systems. http://web.archive.org/web/20110720220124/http://www-03.ibm.com/ibm/history/exhibits/space/space_thinkpad.html http://web.archive.org/web/20110720220124/http://www-03.ibm....
