Lets hope you did not damage it with a failed installation. (if it was firmware) If you just tried the install CD: Most of the time when you change the router (this wifi box....) you also change the IP range. If you set a fix IP on the storage what most people do you do not find it in the new network. The solution woud be a reset, or connect a PC with old IP range, change it to the new.
What do you see in the NAS NAvigator? Quote the device name pls.

Try leaving the key in on for 10-15 minutes. If the blinking theft light stops blinking and goes out, it has reset. Turn key to off, and then try to start it.
