I tried iw while Network Manager was not finding my hotspot, and iw
found it instead.
But suddenly NM found it too! Last time it worked was several days ago.
I really can't understand. I'm happy it's working now, but I'm afraid
it will stop working sooner or later. I restarted several times both
laptop and hotspot, using both Gnome Shell and Mate, and the hotspot
always appeared almost immediately, as it was used to do before.
I then turned on another Nokia 3 hotspot (I have three identical
smartphone, mine and those of my sons). The second one is still
invisible, while other devices, including my own smartphone, can
connect to it with no problems.
Issuing iw scan now has no effect.
For everyone who answered here is the output of dmesg | grep wl:

After the link became ready, I disabled wifi intentionally, and
reenabled after some seconds. Also, I tried many time "iw scan".
I can provide other data if you need it, just tell me.
Many thanks.
