I ran into some issues with my X220 some weeks back and have been trying to fix them to no avail.
As far as I can remember I took some time a few weeks back to install the 1.40 firmware-update and also updated the battery-firmware in the same routine.
I'm not sure If it was immediately afterwards (since I'm using a dock with LAN), but the wifi-card (Intel 6205) wasn't recognized by the OS anymore. No entry in the device manager!
Here's what I've seen/tried so far:
1) What I was firstly able ot see was that the device would sometimes show up after returning from sleep when not in the dock.
2) Since I have an Ericson WWAN-card i switched mPCIe places. WWAN-card works in both slots. No recognition of the Wifi-card in both. >> So it doesn't seem to be related to mPCIe or the board.
3) My guess was a faulty card, so I tried a newly-bought Intel 7260 Wifi-card in the slot.
3.1) The Wifi-card must have been recognized by the BIOS, since the whitelist-fault was presented and I had to remove it to even be able to boot again.
3.2) As the warranty wasn't my concern anymore anyways I flashed a whitelist-disabled version of the 1.40 firmware. As promised, I was able to boot with the 7260 card.
3.3) Yet still, the card is not presented in the device manager.
4) Since my Windows 7-installation had quite some time on its shoulders I reckoned that maybe another OS would be able to properly recognize the card. I just freshly installed Windows 10 and again - nothing is able to bring back the Wifi-card.
5) I used a linux live distribution to check whether that one recognizes any of the the cards. It also wasn't able to see any of the two.
Does anyone have any experience with this kind of issue?
With best regards and a hopeful thanks in advance,

I used a debian live installation running from a pendrive to look for detected hardware. No wifi was found - again for both cards.
I'm really lost for ideas at this point. What really irritates me is that the BIOS/UEFI recognizes the 7260 card with correct VID and PID. Yet still the cards are somehow (I guess) not made available to the operating system.
On another note: I've just noticed that I posted in the wrong forum section. It's about an X220, so the "ThinkPad X Series Laptops" forum would be the correct one. Could a moderator maybe move this topic?

I have the same problem is this the confirmed fix ?
As I have the original card and this is not recognised either ?
I purchased the 7260 as I thought the 6205 was faulty after reseating cpu fan and heatsink.
so neither card is recognised since putting back together. though prior to bios whitelist upgrade it detected the 7260 and would not post.
any help gratefully received.

From looking at the System service parts - ThinkPad X220 Tablet, X220i Tablet page on Lenovo's support webite, the only Mini-PCIe Wi-Fi cards that Lenovo suports in the X220 are:
60Y3247 - ThinkPad b/g/n Wireless (1x1 BGN)
60Y3249 - ThinkPad b/g/n Wireless (1x1 BGN)
60Y3241 - Intel Centrino Wireless-N 1000
60Y3253 - Intel Centrino Advanced-N 6205 (2x2 AGN)
60Y3233 - Intel Centrino Ultimate-N 6300
60Y3195 - Intel Centrino Advanced-N + WiMAX 6250
60Y3209 - Intel Centrino Advanced-N + WiMAX 6250, Russian SKU
Lenovo doesn't officially support 7260 card in the X220, so probaby the best card available is the Intel Centrino Ultimate-N 6300. If you purchase one, make sure it has the Lenovo 60Y3233 model, as generic cards or cards for other brands of laptops will not work in the ThinkPad X220.
