I replaced my existing Wi-Fi/Bluetooth card with this one and Windows automatically detected it and installed the drivers. I was up and running straight away, connected to Wi-Fi very easily. I also tested the screen mirroring using Windows 8.1 Wi-Di to a Samsung F series TV and it worked a treat :-). Although when sending video to the TV screen there was buffering and the sound was out of sync, I guess it has it's limitations. I had another issue with Bluetooth partially working, I could pair but not all features such as headset microphone would work. I downloaded the Intel driver and the Bluetooth completely disappeared from Device Manager! I ended up having to remove the card, start the laptop up, then shut the laptop down and reinsert the card. Everything appeared correctly after restarting, including Bluetooth. All in for the price and if it works with your laptop it brings some nice features and faster Wi-Fi, very pleased.
