My Windows 10 PC can ping my NAS and it can access the NAS web UI by typing the NAS LAN IP into the browser. However, it is hit or miss whether I can see the NAS file system in the File Explorer Network View. Sometimes it is there and most of the time it is not. It did not used to be like this - it was there all the time and I had it mapped to a drive letter. What changed? I have no idea.

Not only my NAS is affected by this, but it's the thing that causes me the most grief because I don't typically need to access my other devices from this PC. Disabling/enabling the network interface doesn't help. Rebooting the NAS seems to help sometimes but that's fairly annoying. Rebooting the PC doesn't seem to help. Sometimes this PC does not even see itself in the Network view. Right at the moment it does but I have no confidence that it will continue to do so. Refreshing the view doesn't seem to change things in any consistent way.

I have no other apparent issues with Windows 10 as regards the LAN, internet connection, etc.

I am on a wired LAN and Belkin N150 router.

For comparison, my Macbook consistently does see the NAS in Finder over wireless to the same router.
