Strange problem since this morning, I got notified that my NAS is not working. Naturally, I rebooted the NAS (Power Cycle) and noticed the LAN light was not blinking, so I changed to a new cable, and it did not work either. 

At this point, I reconnect the NAS, which was directly connected to the x95 base unit and connect it to a network switch which is connected from eth (1) - say eth (0) is the internet connection coming in . previously eth (2) was connected to NAS. NAS Started working. I connected laptop to eth (2) and no response. 

I have power cycled all the x95 in the network. 

I accessed the Web UI and looked at the log. It seems it have error related to it. From my experience, either the OS has issues or the port is physically gone.

Anyone knows any remedies for this? 

It's been stable so far, and I have hardly any headache with x95. I wonder if I can go back to an older version of Firmware — if the problem is related to the firmware OS.
