Summary: Make sure you use the correct antennas. Some laptops only have 2, make sure number 1 and 2 on the old one are 1 and 2 on the new one or your range will decrease. It works perfectly as far as I can tell.
Summary: I went from barely any signal to maxed out signal. Just make sure you have the proper tools to install it and you'll be fine. I've been using it in my laptop for over 2 years now and the signal is still going strong. What else would you expect from an amazing company like Intel!?
Summary: This wireless card is great! The ultimate N 633 was quite easy to install and I only need to install a new wifi driver from intel to get the card going. For context, I previously had a stock 2012 x51.
