I have a DL4100 with 4 4tb drives arranged in a mirrored array (a 10, I believe). It’s worked flawlessly since I got it several years ago. I recently moved out of the city where I had a fiber connection to the internet to a country location where my internet connectivity is provided by an ellipsis (Verizon) jetpack mifi.
I didn’t really care if the NAS was accessible away from the house, so I hung it off a Linksys WIFI router so that I could address it and connect to it from the house wirelessly. That worked for about 2 weeks.
This morning I tried to get into my photo archive on the NAS. It just hung. I walked into the room where the unit sits and pressed the up and down buttons next to the LED screen (which was just showing the device name) and it wouldn’t scroll through the panels. Since I couldn’t access the thing from the computer or get the screen to move, I held the power button down till it shut off, waited a minute and rebooted. I got the flashing blue light and a blank LED display. I left it for about an hour with the fans running. Finally rebooted it a second time using the poer button, same results. Tried resetting, same results.
All of that to ask this question… Is this a result of it not being accessible to the internet or is it a more local hardware issue?
