Your log output does not show a crash. What do you mean by “crashing randomly”? Just a disconnect or that the NetworkManager daemon does a core dump or a external software that NM uses like pppd for example?

It dissconect from wifi, and can’t connect again, unless I do this:
sudo systemctl restart NetworkManager
and this command takes 30 to 90 seconds!
any ideas?

I can give any other log if anybody can help.

Have you noticed that it only happens after your system has been suspended? I have this sometimes.
