General NAS-Central Forums

My NSA310 worked properly for about 2 years. One day it became unreachable, the NAS seeker can't find it and my tv can't see it too. If i do a hard reset, it works properly for about twenty minutes and after that same problem comes again. Nothing on nas seeker and if i go the ip adress only see a grey screen but no error messages. Anbody has the same problem or a soultion? Thank you.
