Lenovo Y50-70 Non Touch Model wifi card help

Hi,

 

I have Lenovo Y50-70 (Non-Touch) With I7-4th gen. GTX 860mx (Y50-70 Laptop (Lenovo) - Type 80EJ )
My wifi card is weak and always keep in disconnecting the network. I am thinking of replacing it with the new Dual AC wifi card.
Since my previous card does not support the 5Ghz. Currently, I have 
Qualcomm Atheros AR956x Wireless Network Adapter

Came across this PDF 
https://download.lenovo.com/consumer/mobiles_pub/lenovo_y40_50_series_hmm.pdf
on page 91 they mention some list 

thinking of this 

I am not sure about the whitelist and other bios related stuff. Hope some can help me finding compatible Wifi card with the Dual channel support.

Re: Lenovo Y50-70 Non Touch Model wifi card help

There is a known issue with Windows 10 version 1903 and Qualcom WiFi adapters, so you may be running into that problem.  

 

Lenovo does usually have a whitelist, so if you want a AC 7260 card, you should look for one that has a Lenovo FRU of 20200552 because it shipped in Y50-70 models 80DT and 80EJ such as this one per the partlist.     

 

Note:    To verify it works with your model, I would go to https://support.lenovo.com/us/en/partslookup, enter your serial number or MTM, and check the list of Wireless LAN cards that are compatible before ordering. 

 

Cheers,

Re: Lenovo Y50-70 Non Touch Model wifi card help

Hello SIr,

I have checked and found the model number with me is 

Y50-70 Laptop (Lenovo) - Type 80EJ

 

 and the following are compatible as per the https://support.lenovo.com/us/en/partslookup,  but none looks the support 5Ghz
comaptible parts.PNG
only part number mention being compatible is 
20200558
20200570
20200557
 
but not this 
20200552
https://download.lenovo.com/consumer/mobiles_pub/lenovo_y40_50_series_hmm.pdf
Its present in PDF though so my question remains is this compatible or need to forget about 5Ghz.
or some tweak eg adding whitelist in BIOS will work.

Can you help me with? Thanks in Advance.

The one I see is shown below.    It is a dual band (2x2Wi-Fi + Bluetooth 4.0) adapter that supports 802.11abgn, 802.11ac, 802.11d, 802.11e, 802.11i, 802.11h, 802.11w at 2.4GHz and 5GHz speeds.

The Intel AC 7620 NGFF card you need will look like this one and have both the part number and FRU P/N as shown below, such as this card from Amazon   https://www.amazon.com/Intel-7260ngw-Wireless-Lenovo-Thinkpad/dp/B011XB19VS

You can use the Intel WLAN Driver for Windows 10 (64-bit) - Notebook driver found on Lenovo's website, or get the latest driver from Intel for Windows 10

 

 

Hope that helps,
