how mount the usb drive from Linux

From a linux box, I'm trying to mount the drive I have plugged into the router.

Following the instructions here:

I get this error:

mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

The RedHat guide says if I see that error:

Please verify the permission on the folder on you windows machine and try again mount the share folder.

Looking at the drive permissions on the router's 192.168.1.1 page,

I see Write = "All - no password" Read = "All - no password"

and no way to "verify the permission" on the folder or change anything (like, assign a password for example).

If anyone knows how to mount this drive I'd appreciate it.

I very much want to mount it rather than unplug it because Windows runs File History backup on it constantly.

Also, I tried to set permissions on it using windows but the new settings would disappear when I clicked "Apply"

When I view the permissiions in windows, nothing is checked.

Router Firmware: 1.0.2.4_9.1.86

Linux Version: CentOS 7.3
Windows Version: 10 Pro

That's all the detail I can think of.

Thanks!

Oh ...

I cross-posted to stackexchange the view from the linux side here:

I've found posts about the same thing for other netgear products like, here:
