I'm blocked by my ISP which doesn't want to replace SMBv1 in its devices
by
something more up to date.

Thanks anyway for your answer.

I forgot to mention, you might also need to add 'ntlm auth =
yes'

If your ISP provided? router is anything like mine, it will probably by 
using a version of Samba circa 3.0.x (note, I do not use Samba on my 
router).

Whatever it is, it will be a GPLv2 version. They do this because they 
tend to alter the code and do not want to publish it, they cannot do 
this with GPLv3 code. Be interesting to see what they do when there is 
nothing to 'talk' to SMBv1 ;-)
