Replace wifi card on a X240

2017-11-18, 14:18 PM

Hello.

 

Earlier this year I buy a second hand Thinkpad x240. It is provided with a Realtek RTL8192EE wireless card.

This card had two problems:

- No 5GHz

- A firmware "cardboard-based" (frequently disconnected)

 

I planned to replace this wifi card and chose an Intel 7260NGW. It was difficult to know which card is accepted, but I read in some place that the Intel 7260 is accepted on Thinkpad X240. But after a try, this card is not accepted. The computer is blocked by bios :(

 

So, my question is simple: Which wifi card can I use on my Thinkpad X240?

Solved! See the solution

Hello and welcome,

 

To pass the BIOS whitelist a card must be a listed model AND have a Lenovo FRU number.  A "generic" 7260 won't pass.

 

The models and FRU numbers are listed in the BOM:

I don't know who ships to your location, but trying "04X6007" on The Google turns up quite a few via eBay and Amazon.

 

Please bear in mind that I can only go by what I read in the BOM.  04X6007 appears to be a 7260ngw AC card.  Please verify yourself as well.

This is what I have done: Search for a wifi card compatible with Thinkpad X240 and finish by buying a Intel 7260NGW AC card. But this card is not authorized by the X240.

As above: did you buy one with a Lenovo FRU number?  The correct FRU number?

No, because at this time I didn't know it exist. I didn't know the Lenovo DRM on my own computer was so vicious. :smileysad:

Hopefully the right FRU will get you there :)  Any chance you can return/swap the one you have now?

 

Good luck,

Z.

 

(Beween you and me, I'm not crazy about the whitelist either :(  It's been with us since way back in the IBM days.  It's my understanding that the newest ThinkPads don't enforce it - but I haven't personally verified that myself except on my TP Yoga 370.)

Maybe. But the return shipping cost is maybe more than the price of the card. I need to check.

 

Thanks for your help. ;)

I hope Lenovo, one day, will release a BIOS update that deactivate this whitelist system.
