mx 19 nuc i3 wifi locked

After updates I found wifi locked. the rfkill list command reports: soft locked = yes 
rfkill unlock 0
  ifdown -a then ifup -a and the connection works. at the next start, however, we are without a network and you have to repeat the commands above. the system is mx 19.4 and the pc nuc7i3bnh

Resolved ! if this happens to someone just add three lines to
/etc/rc.local
rfkill unblock 0
ifdown -a
ifup -a
