    2) The output of `iwlist scan` to see if the network you re

looking for is detected from the hardware.

This is interesting, I didn't know this command. It would rather strange

if the hotspot is shown by the above command but not by Network Manager.

No, it would not be strange at all.  Network-manager is in it's own

time-zone, and is often rather strange and hard to figure out.  Sometimes

you must be patient, it does not scan immediately.

For CLI tools I prefer 'iw' to the older iwlist command, but either may

help you.  If the device is scanning and finding other ap, then it

probably is a network-manager quirk.  It often misses/adds/deletes aps

from the list IME.

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.

Good Luck,
