I have a Lenovo X-220 that currently has a wireless N card installed.
A few days ago, checking System Update, I noticed the updated driver for Intel Wireless Cards (version 16.1.3, details available here: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS036007) which expressly indicates support for Intel's AC 7260 wireless card and expressly for the X220.
I was previously aware of the whitelisting issues with unsupported mPCI wireless cards on Lenovo systems, but understood this update to indicate that Lenovo was adding support for the AC 7260, correcting the issue experienced by folks earlier in the year.
Accordingly, I ordered one and was somewhat surprised this evening to still receive the message "1802 unauthorized network card is plugged in. Power off and remove the miniPCI network card".
Can anyone shed light on this? Is there some other step I need to take to make this work? Or have Lenovo actually issued a new driver expressly indicating support for the card while neglecting to update the BIOS whitelist to enable it to work.....?
Any advice appreciated.

Hi Greg_S, and welcome to the Lenovo User Community!
I too want to believe that a software update makes my old X220 support a newer wireless card! But I'm pretty sure the release note means the software supports all those cards respectively in the systems they are built into, and not that it magically makes all those cards work in all those systems!
Hope this helps!

4 years on, this question is revisited. Thinkpad X220 options for wireless 11/AC.
Connecting to NetGear R8000 Nighthawk and the wireless keeps dropping off and losing packets.
I would prefer to use an AC wireless connection because of the speed, coverage, signal strength.
I've investigate USB wireless, but this machine only has 2.0 connectors.
1. Any current recommendations on replacing the mini half card with 11-AC capability?
2. Does my BIOS have to be WhiteList disabled? I never did discover where to get a replacement BIOS.
Thanks. I love this X220; fast and reliable ( except now for wireless connections )

I installed an Intel AC7260 into my X220 a few years ago, and I did have to install a modified BIOS. God knows where I found it, and it made me nervous installing it, but it worked, and continues to work fine even though the X220 is not my primary laptop anymore, I use it more for testing things.
So it's definitely possible.
Edit: Miraculously, I found the installer! I looked thru some of my old Acronis disk images, and I did a full Acronis disk image of my X220 before I upgraded to Win10 in 2015. And lo and behold in my downloads, there was the whitelisted bios file that I found years ago. It's based on Bios 1.39.
Use at your own risk of course.
