Was going crazy trying to find a Driver for the NIC for windows 8 64 bit Pro. I have a Dell Latitude E6410 and the driver from Microsoft worked for the most part but I was having issues connecting to my Windows phone 8 device (Nokia 920). First I though it was my phone but when I tried other devices like my Surface I could connect with no problem. I am also running Windows 7 32 bit, when I boot up that OS I had no issues connecting to my phone. I also had issues with stable connections to my 5Ghz Wi-Fi access point. Well if any of these symptoms sound like something that you been going through then check this driver out. I used the 43224AGN 802.11 a/b/g/n 2x2 driver and now everything seems to work. I will give it a week and report back. Hope this helps someone out there.
