Only the former : he's not skilled enough to do the latter.
I suspect that originally someone set it up for him
& altered some default setting(s), then when he restarted it,
the default setting(s) returned & that's not working with my software.

There are none.

The permission is '644', which is ok for my cellpbone's hotspot.

It shows nothing : see output below.

Thanks for your usually very helpful suggestions (smile).
Here is the output via 'wpa_cli' as I start & stop Wifi.
I connect & disconnect with my cell-phone 'Athene' + landlord's service,
whose name is 'Watch Iovedocs ... ',
& which I have to access via 'wpa_gui' (I used 2 terminals).
output of 'wpa_cli' as I wake up Athene's service :

I've had difficulty determining the exact sequence of commands with wpa_gui.
It seems to be : 'manage networks' -- 'edit' to add password -- 'save' --
'scan' : a list of services is offered, a '5200' is double-clicked --
back to 'current status' -- 'connect' & it fills in the details
& takes another 15 sec to get an IP address & I/net cb accessed.
Any further suggestions very welcome.
