I have a similar problem. My LS-250GL was accidentally unplugged. After plugging it back in it is unresponsive. Launching the Buffalo NAS Client Utility all the IP Address, Subnet Mask, MAC Address, etc fields are all blank. None of the menu options work- Setup/Change IP Address or Setup/Configuration Settings. Trying to connect to the NAS generates this error, “Network can not be found. Confirm network cabling and connection.” I checked the cable and rebooted the NAS, PC and router with no luck
I connected the NAS directly to my PC and tried using the NAS Client Utility with no luck. Trying to connect to it through a browser using the default IP address (192.168.11.150) didn’t work either (connected directly to my PC or through my router).
I pushed the red reset button for 15 seconds to restore the factory defaults and that didn't work either.
Help!?
