Also, check on NAS what minimum and maximum SMB versions are enabled.

Correct concerning the md4 module. Only certain routers requires it.

I have one old NAS that I must connect via 2.1. 2.0 and 2.2 does not work. Yet another device is reverse, it must be set to vers 2.2. it all depends on your client that you are trying to connect to. What is the error you get when trying to manually mount the share?

Thanks for sharing that gives me hope that vers 2.1 or 2.2 could be the way to fix it

This is the error I get:

mount: mounting \\192.168.11.13\home on /tmp/mnt/backups failed: Operation not supported

The NAS has enabled all those SMB versions

Host script results:

Can you please post the mount statement you're using that gives you this error?

And the highest SMB version that the RT-AC68U gives you is v2.0, right?

I suppose the other workaround that might be possible here is enabling NFS on your Synology (if compatible), and utilizing that method?

Hi @Viktor Jaep, here is the screenshot from Putty.

That is correct RT-AC68U gives me v2.0. as per attached picture.

The SMB version supported by the router's Samba server has nothing to do with the SMB version supported by the CIFS client module. Do not conflate the two.

How do you determine what versions of SMB the CIFS client module can support?

Try

Hoping this goes without saying, but did you change myname and mypass to the username and password of your account on your NAS?

I ask, as from the screen shot that you posted, it does not look like you did.

Yes, I did try with the actual NAS username and password, I got the same error message.

Unless there are any other ideas, I think you're at an impasse. The router only support a max of SMB v2.0. The Synology only supports a min of SMB v2.1. Unless there's some way to get your SMB stack to a higher version, your only option is to obtain a newer router. Alternatively, you could see if you can get NFS working, and see if your router and Synology can agree on that standard?

The only other thing I can think of is the username or password has a character that is being misinterpreted by the shell. More the username as Vic has already base64 encoded the password in the script.
