Hi Larry,
I experience some other strange behaviors. The chip cant connect to my old ASUS
router (RT-N12E_B1) and cant even see the mobile hotspot of my smartphone. So,
logically it cant take the best network, if it doesn't connect to my router or
my smartphone - even directly lying beside it. I also cant reconnect to my
test-network. The networks "Gonzales" and "TPC_install*" are both hosted by my
router.

The only difference between the other networks and my routers one is the
different "Country" value (at my first look).... And my hotspots network
"Lineage 14.1" is not visible too. (And so i cant connect to it too.)
Thank you and anyone for your/their effort!
Obviously, the driver fails badly at roaming. It has associated with an AP with
signal of -93 dBm when -50 is available, and appears to associate with the first
one it sees. Unfortunately, I do not have the necessary understanding of the
chip or the driver to fix that problem. My only suggestion is that you determine
the BSSID of the strongest AP and use the connection editor in NetworkManager to
force a connection to that AP.
Without an over-the-air capture of the beacon from either your old ASUS router
or the mobile hotspot, I have ne idea why the chip cannot connect to them.
