I am having some trouble with my Wireless card on my laptop. I am using the Lenovo thinkpad X201 which is having inbuilt Lenovo Wireless card. I think that it is Realtek 8172/8192SE card. Now I want to change this card because it is lacking performance. But I donít whether it matches to my laptop or not. I heard some conflicting reports from other users who tried to change their wireless card. They say that there is BIOS locked. It didnít take other party or third party peripherals to it. It only takes the card that had been supplier by the Lenovo. I am confused now. I donít know are they saying truth or not. Any manner I need a correct answer as soon as possible. Thanks for any replies.
