I just got this NAS, everything works fine, but after some few hours my NAS is not accessible anymore. I gave it a static ip address configured in my router, and still shows up in my LAN when I scan it for attached devices. When I pull out the power supply and put it back in the NAS boots up just fine but after a few hours it just happens again. Also did the software upgrade but it doesn't seem to work.
Anybody any idea?
is the static IP of the NAS out of the DHCP range managed by your Router? Check the lease time associated with IPs, this is set in your Router.
If there's possibility of duplicate IP, change one of the IPs permanently.
