When connecting to SMB my RB5009 crashes and reboots without any logs.
Setup:
/ip smb users set [ find default=yes ] disabled=no name=guest password="" read-only=yes
/ip smb users add disabled=no name=user1 password=1 read-only=no
/ip smb set comment=RB5009 domain=MSHOME enabled=auto interfaces=bridge
/ip smb shares set [ find default=yes ] directory=pub disabled=yes invalid-users="" name=pub read-only=no require-encryption=no valid-users=""
/ip smb shares add directory=/ disabled=no invalid-users="" name=root read-only=no require-encryption=yes valid-users=user1
But the same configuration works correctly on hAP AX2 and hAP AC2.
Also it does not show up on the Windows 10 network, connect via IP.
Upd. It not crashes only if set require-encryption=no and it can connects if username is user1 and password is 1, otherwise not connecting.
