First download the IT Administrators version of Intel Wireless Wi-Fi Driver. You can use this link to download the latest version.
Extract the downloaded file to a folder.
Then open the Device Manager by right clicking the Start menu. Go to Network Adapters and expand it. Find Intel(R) Wi-Fi... and right click "Update driver". Select second option, which is "Browse for drivers on your computer". Then find the folder that you extract the Intel Wireless Wi-Fi Driver. Continue to update and it will (hopefully) be updated like mine.
I hope this helps.
