You have the Intel AC instead of the N, same problem, you’ll need to download the Intel 3165 driver from https://www.intel.com/content/www/us/en/support/articles/000005559/network-and-i-o/wireless-networking.html

Then manually update the Bluetooth adaptor in device manager.

For some reason the win10 update installs its own driver that only covers the Bluetooth side of the integrated Bluetooth/wifi adaptor.

Check my post, after windows update, the wifi is detected as a bluetooth only device, update the driver manually

After Win 10 Upgrade Wifi Card Missing!

 

[AG]

I had the same problem of missing wifi device on a 3S after latest Win 10 1803 update.

Open Device manager, expand bluetooth, there was a generic bluetooth adapter listed, right click update driver. The wifi card is both wifi N + bluetooth device, but seems to be picked up as bluetooth only.

Use this driver from microsoft catalog update for Win 10, choose “Realtek Semiconductor Corp. – WLAN – Realtek RTL8723B Wireless LAN 802.11n USB 2.0 Network Adapter “.  It should be the AMD64 bit driver, not 32 bit (click the name to see details of the driver).

https://www.catalog.update.microsoft.com/Search.aspx?q=802.11+n+WLAN

Download the CAB file, extract using 7zip to a folder, then in Device manager, Bluetooth – Update Driver.

“Browse my computer”, “Let me pick from a list of available drivers on my computer”, “Have Disk”, browse to extracted files, then OK and scroll through the list of available device drivers, select “Realtek RTL8723B Wireless LAN 802.11n USB 2.0 Network Adapter”.

Mine is showing version 1030.26.801.2017 from 31/01/2018.

Restart computer and you should also see “Realtek Bluetooth 4.0 Adapter” auto installed in device manager – bluetooth, and the WLAN device in Network Adapters.
