Replace Yoga 2 Pro wireless card - will it be accepted?

I wish to change the wireless module in my Yoga 2 Pro to an 802.11ac model

 

http://www.amazon.com/gp/product/B00GUNZUG0

 

Problem is I read of others encountering a rejection by the BIOS. Mine has already been updated to version 76CN43WW long ago, and currently operating Windows 10.

 

Can I still acquire that AC card and have it work properly?

Re: Replace Yoga 2 Pro wireless card - will it be accepted?

Hi icelava  , 

 

Welcome to the Community Forums. 

 

Based from the hardware FRU list (item 11 page 62), offered WLAN  for the yoga 2 pro :

WLAN/BT, Intel 7260BN 2x2BN+BT PCIE NGFF WLAN  and was not offered any AC WLAN

 

Usually , "unauthorized network card" are encountered during this scenarios. 

 

There are those that manage to upgrade it to the AC 7260 done here on this discussion using Windows 8 and also on this article  . 

 

In Windows 10 , seems that further connectivity issue are being encounted and each fixes are different from the others as here in this thread. 

 

Issues finding resolution is not OEM issues alone but also being shared by the software operating system. 

 

It would be better to test it on a spare first before deciding on any upgrades for purchase. 

 

Highlighted discussions a bit lengthy so just take your tinme on the review.

Hope this answered your query.

 

Regards

"It would be better to test it on a spare first before deciding on any upgrades for purchase."

 

So you are suggesting I go purchase another Yoga 2 Pro, and go buy the AC wireless card anyway, so can I test on a "spare" before making any purchase decision??

Hi icelava , 

 

Greetings. 

 

Seems not logical to buy something just to have a spare device only for testing. 

Take note that most OEM branded machines have whitelist and what is aceptable are those listed on the hardware manual indicated above.

 

What I do is grab my extra non purchased WLAN card from another pc and see if that would work. For other cases I have the end users take it to their company IT or service centers to see if they have a spare WLAN card (which most likely they have) to test. 

 

To purpose here is to avoid unneccessary purchase without assurance that it would work. 

On the similar threads are folks that took the risk as their own knowing that doing this is outside the OEM recommendation.

 

Hope that answered the query clearly.

Update us what would work best for you.

 

Regards

Re: Replace Yoga 2 Pro wireless card - will it be accepted?

Well, the definitive answer, after managing to find and buy an Intel 7260NGW, is that BIOS 76CN43WW will not allow the computer to operate and boot into the operating system - unauthorized wireless card. This is ultra silly.

 

So I tried to revert the BIOS down to version 76CN31WW but the updater tool does not allow regression either.

 

Any good ideas to go about this?

Ok so I discovered the BIOS itself has a "BIOS back flash" option that has to be Enabled in order for re-writing back to an older version.

Reverted back to 76CN41WW as according to the lengthy thread https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Re-Yoga-2-Pro-Wifi-Problems/td-p/1452437/p...

But still no joy - Unauthorized network card. I am unsure exactly what BIOS version should be reverted to for this to be accepted.

Hi @icelava,  I am in the exact situation now and searched this forum hoping to find a solution.  Wondering if and how you managed to resolve the ' Unauthorized network card' problem and if there was a right BIOS version for it?  Would really appreciate your advice.  Many thanks

Hey there, I could not find an appropriate BIOS version that would accept the new WLAN card. Eventually the laptop had other hardware problems and I gave it away.
