Is the IP correct? Windows firewall? Your windows 10 share is called router? Can you reach the share from another machine? Did you try if the mount really works? Create file? I remember a case where mount gave out no error but couldn’t mount properly.
This is also working for me with Windows 10:
mount -t cifs //192.168.1.115/test /mnt/backup -o username=markus,nounix
I have to use username/pasword in backup settings for Windows 10 backup test share tough I gave everyone network and file rights on the share but it’s working.
Sorry for German screenshot…
It’s dirty because updates may erase your changes but the file to change is /etc/e-smith/events/actions/mount-cifs:
