Yoga 920-13IKB with Intel 9260 Wi-Fi adapter

2018-04-18, 20:51 PM

Warning for users that installed the Intel 9260 vPRO on Yoga 920.

The current drivers downloaded from Intel are:

Intel Wireless-AC 9260,  Driver Date 2/6/2018, Driver Version 20.40.0.4

Intel Wireless Bluetooth, Driver date 2/8/2018, Driver Version 20.40.0.3

With these drivers everything works fine.

 

The latest windows update tried to change the driver for the Wireless to 20.50.0.3 dated 3/14/2018, which appears to be a Compal Intel driver.

There is no explanation about the changes in the driver and unfortunately with 20.50.0.3 the transfer rate drops about 15% compared to the 20.40.0.4 supplied by Intel PRO-Set package.

I had to roll back the Wi-Fi driver to 20.40.0.4 Dated 2/6/2018 to get the transfer rate back up.

After installing latest windows update build 16299.402 I tried again the driver update to 20.50.0.3 dated 3/14/2018.

I don't see the data rate degradation anymore, here are the results:

On 04/25/2018 windows updated the driver again to 20.50.0.4 dated 3/19/2018.

I did not see any issues with this latest driver update.

On 05/01/2018 the latest PROSet wireless software with driver 20.50.0.4 became available to download directly from Intel support, see link below.

 

https://downloadcenter.intel.com/product/99445/Intel-Wireless-AC-9260.

 

Also I updated my Yoga 920-13IKB to Windows 10 x64 1803 Build 17134.1.

Everything worked fine after the windows update.
