(Frustration level 10)
I have a Synology DS213air connected via Ethernet and a switch to my Windows 7 PC. Wireless is switched off (that's an other problem).
Synology Assistant never has any problem finding the NAS:
On rare occasions I can map the drive to Windows' file system, but already after a couple of minutes I get the error:
Synology Assistant still finds the NAS. Now, when I try to re-map the drive, after half a minute or so of "Connecting to server" I get the error message "The network path was not found".
Sometimes mapping succeeds after half a dozen tries, sometimes it doesn't work at all, not even after restarting the NAS and restarting the PC.
The DS213air is very versatile, which is the reason why I don't find configuring it straightforward. Any pointers to a possible cause for the continuous disconnecting and a cure are greatly appreciated.
PS: I can't remove the switch, because I also use it for my connection to the Internet.
update
Mapping in Windows Explorer instead of Synology Assistant doesn't seem to make any difference. There's a slight improvement when I use a static IP address: when I click a NAS folder in Windows Explorer there's no response for more than 2 minutes(!), but then I get to see the folder's files.
In Directory Opus (an Explorer replacement) there's a shorter pause (still about 1 minute), and then I get this error:
but oddly enough after that the folders and files are accessible.
