J'utilise une version alternative du firmware : Asuswrt-Merlin 384.17 (26-Apr-2020)
https://www.asuswrt-merlin.net/
Les fonctionnalités indiquent : Updated Samba version (3.6), with SMB2.0 support
384.4 (16-Mar-2018)
Samba protocol support can now be set to
SMBv1, SMBv2, or SMBv1 + SMBv2 (the new default).
This will result in a performance drop on all models but the RT-AC86U, but will be more secure.
Ideally, people should change it to SMBv2 only, and then reboot all their client devices to start using only the new protocol.
