Windows 10: Wifi not working on Lenova H535s

My Lenova H535s desktop does not show any WiFi networks. Works OK on Ethernet cable. Have tried all the usual fixes like updating all the drivers via Lenova web site, resetting the network adapters etc., and running network commands netsh winsock reset etc, but to no avail.

Wondered if it could be caused by Windows 10 update Feature update to Windows 10, version 20H2?

It it safe to uninstall that update on its own?

Any thoughts? Many thanks. Robert

:)

Have tried reloading all network adapters and resetting network commands (eg netsh winsock reset).
All the drivers are up to date, and have run a Lenova hardware check and all OK.



Any ideas? Thanks. Robert

What is shown in device manager for network adapters both under the heading network adapters
and check to see if any unknown devices are listed.

Hi Paul
Very many thanks! Ran your Find_ANY_Problem_Devices.bat and replied No problem devices found.
Around two years ago on the Lenova forum there were similar probs (no WiFi) reported, and I think it might have been due to a Windows 10 release. I also have a Lenova laptop running under WIN10 with latest WIN release version 20H2, and that laptop works fine.
Any further ideas? Thks. Robert

What does that mean? Could Wireless card in hardware have become loose?


Ran Network trouble shooter and responded:
Your computer appears to be correctly configured but the device Detected or resource (DNS server) is not responding.
Do you know what that means?

Checked WLAN AutoConfig and running and auto, so rthat is OK. Thks. R
