These screenshots were taken when you were using the Wifi connection - I see the WiFi icon in the Taskbar. And when you use a wired ethernet connection on your laptop, then you are able to connect to the Nucleus using File Explorer?
If that’s the case, then it does look as though there are two separate networks in play here. So, right-click on the WiFi icon to go to your Network and internet settings, click on properties, and tell us what the IPv4 address of your laptop connection is.
Then do the same for the wired connection - right-click on the network connection icon in the Taskbar and go to the properties to display the IPv4 address for that connection…
“In addition, in my experience, most network routers etc use the IP range 192.168.1.0 to 255, with .254 normally being the router IP. The Box 2 creates a new network with range 172.24.1.0 to 255 by default”
Perhaps the best thing is to tell us in detail what your network setup is - hardware and connections. Here’s mine as an example. Pencil and paper will be good enough to document it - you don’t need fancy graphics.
If this is the case, then my suggestion would be to move the Netgear switch to the output of the Bitdefender and connect all your wired devices (including the powerline adaptor - another class of device that can give problems) to the switch.
That way, the new topology will have all devices connected to a single network with addresses in the range 174.24.1.x.
Once that’s done, we can take a look at why you are having difficulty connecting the Nucleus to the NAS.
Right that’s that done! and all now appearing on the same network. As a test I have dragged and dropped files from my NAS to the Nucleus, and seems to be going well. I want to use the Internal Storage of the Nucleus as my main folder and back up to the NAS (does that sound sensible?).
So the issue left is now adding the NAS and Internal Storage as folders? I’ve tried copying over the file path from windows explorer, but just get an error message?
I would also like to offer a persona and genuine thanks for your advice, support and patience. I would have got nowhere without it. So, thank you.
