Lenovo g50-70 wireless card upgrade issue

Currently my Lenovo G50-70 has a qualcomm atheros ar956x that has severely poor performance, so I wanted to upgrade to a Wireless AC adapter. after recieving the part listed as "WirelessLan_Intel, Intel 3160 1x1AC+BT PCIE NGFF WLAN" in the HMM, it booted to a screen that said "Unauthorized wireless card, please power off and unplug". So in finding that this card didnt work, I ordered the part listed as "Ltn NFA345 AC+BT4.0 PCIE M.2 WLAN Card For Lenovo B50 Series ,FRU 04X6023 20200579" and had the same result. After messaging the lenovo cs twitter and having them tell me Im basically SoL I decided to make a forum account.

 

Can anyone help? My BIOS and drivers are all at the most current version. I can supply any additional information needed. Included are photos of the current and new cards, the new one has a green dot on itBsX26cul.jpg

Re: Lenovo g50-70 wireless card upgrade issue

What is the machine type and model of your machine? 

Who did you order the parts from? Lenovo/Encompass or other.

 

The OEM Intel 3160= part 20200418=04X6034 (picture below).

WirelessLan_Intel, Intel 3160 1x1AC+BT PCIE NGFF WLAN

Your new part is 04X6022 <this failed?

LITEON HA335WB3351X1 BGN+BT4.0 M.2 COMBO  <<note BGN

Your other new part is 04X6023=part 20200579 <this failed?

Nono I tried the Intel 3160 that was listed in the HMM and it did not work so I returned it and got the Ltn NFA345. The Ltn also did not work despite stating it would in the HMM.

Re: Lenovo g50-70 wireless card upgrade issue

What is the model number of your machine? and which part is the OEM part that came with the machine(atheros)>realtek, broadcomm, etc.

Are you window 10?

new part 04X3022  ..researching this part

new part 04X6023=part 20200579 NON intel 3160 should work, unless you got a non Lenovo version. 

 

I did ask earlier where you got the parts from.

Lenovo likes users to install their version of a part, especially WLAN cards.

Model Number 20351, the part that came with the machine is the qualcomm atheros ar956x. Yes, I am on windows 10. I got the new parts from 3rd party stores online as I am not in the US at the time. One from Amazon and one from Aliexpress. I just want a wireless AC card that works in this model

Re: Lenovo g50-70 wireless card upgrade issue

The 2 new parts appear not to be Genuine Lenovo parts. You would have to check with your two 3rd party sellers.

If you can disclose your location, maybe a forum user with a AR956X in your current area can assist.

 

Whilst in the US,were you on win 8/8.1 or win 10? Which version of win 10 are you on? I would not rule out a issue with Microsoft software.

Aliexpress is showing TWO 04x6023 items(sneaky).

Download each picture.  Compare those funny numbers. 

 

https://www.aliexpress.com/item/Atheros-NFA345-802-11ac-Bluetooth-4-0-NGFF-Card-FRU-04X6023-for-Leno...

 

https://www.aliexpress.com/item/Ltn-NFA345-1x1AC-BT4-0-PCIE-M-2-WLAN-Card-For-Lenovo-B50-FRU-04X6023...

 

I would avoid ordering NFA335 item from this vendor. Not Official Lenovo part.

Ltn-NFA345-1x1AC-BT4-0-PCIE-M-2-WLAN-Card-For-Lenovo-B50-FRU-04X6023-20200579_jpg_640x640.jpgAtheros-NFA345-802-11ac-Bluetooth-4-0-NGFF-Card-FRU-04X6023-for-Lenovo-G70-70-G70_jpg_640x640.jpg

 The official part can be found here (out of stock).

https://www.encompassparts.com/item/10195427/Lenovo/20200558/Cl_Wired_Lan_Adapters

(Below. No longer available picture shows 04x6023. Again compare the funny numbers).

https://www.encompassparts.com/item/10631347/Lenovo/20200579/Cw_Wireless_Wan_Adapters

 

You may have to call Encompass direct for sub parts availability.

encompass 04X6023.jpg

The part that came with your machine, 20200558, is Liteon,NFA 335,

contains a Qualcom AR956X.  = 04X6022.

Re: Lenovo g50-70 wireless card upgrade issue

You will need to purchase a "Lenovo" branded adapter, not a generic or 3rd party part.  Also - if the part is branded for a different manufacture it will not work in your notebook.

 

This is due to the "whitelist" of accepted parts in BIOS.  If the BIOS / Hardware ID string is not in the list or carrires a different branding other than Lenovo it will be rejected.

 

I would adivse downloading your Maintenance Manaual and look for an AC wireless adapter in the parts listing twords the back of the manual.

 

Good luck.

Re: Lenovo g50-70 wireless card upgrade issue

Hello,

I got the same message("Unauthorized wireless card, please power off and unplug")

after installing Intell Dual Band Wireless-AC 7265, WLAN adapter(see picture)

This adapter is listed in the HMM(WLAN, Intel 7265 2x2AC+BT PCIE M.2 WLAN) so I thought it would be no problem.

 

Thanks for your help.
