Windows 10: Network shows on PC "Manage Known Networks" but not on Available Networks

Several PCs use the network OK, and the problem PC is only 2 metres from the Router.
It shows lots of other networks, but not the one which it should show, as used by the other PCs and showing in "Manage Known Networks" . I put it there anually.
Trouble shooter does not help.
It has been working for years, then just stopped.


Windows 10 Version 1903 Updated auto.


I think it stopped working after an upgrade.

WiFi appears in Manage Known Networks but not in Show Available Networks

Detected yes but in Manage Known Networks and not in Show Available Networks.

 

WiFi appears in Manage Known Networks, not in Show Available Networks

The list of WiFi connections shown when you click the WiFi icon in the taskbar is a list of all the signals that can currently be seen by the WiFi adapter. The list in Manage Known Networks is a list of all those you have previously successfully connected to, whether or not they are currently available.

The only plausible explanation is that for a while that WiFi signal had been turned off.

 

Available Networks Not Showing

My list of available wifi networks has suddenly stopped showing in windows 10. The list of networks is not showing when I click the system wifi icon in the notification bar. The list of networks does not show using 'show available networks' in Windows
Settings. Windows Settings will crash if I go to the WiFi page and select 'Manage Known Networks'.

I am connected to the internet using my normal WiFi. I created a wlan report. It seems to show that the wlan is working fine. I can list the available networks using the cmd line 'netsh wlan show networks'. They all show up as they should.

So, it appears the hardware is working but some windows module has stopped working and providing the list of available networks.

Any ideas how to fix this?
