Readynas duo V2 disapear after a while

Hi,

I seem to have a similar problem. Having had my Readynas Duo for 2-3 years, I am now experiencing a similar problem as 'dieu'. It has worked well during the past, but when I changed network provider (using a mobile internet usb stick plus a dovado tiny wireless router) I now have troubles finding the NAS. Since my new mobile internet router established a DHCP network in itself, I had to change my NAS subnet to x.y.1.static_ip instead of x.y.0.static_ip. I dont know the proper technical terms, but you probably know why these things happen and if and why this could cause my problems. I am not sure the NAS has ever connected and successfully backed up anything since I re-engineered the network.

Here a brief description of events:
First (around three weks ago) I rebooted the NAS and it got stuck at 41% of file system check (waited two weeks, not very active as I only use it for family backup and I am not very knowledgeable in network IT).

So I rebooted it and suppressed the power button on reboot to force it to skip the file system check. I could then access the NAS via RAIDar and ping it, but https:NAS_IP/admin didnt access frontview. In my router (not the mobile internet one but another one wired to the NAS) I could see that NAS was connected. I access this one wirelessly from a PC.

Then I rebooted the NAS again - without pressing down the power button at startup - and I could follow the file system check in RAIDar in real time. I got until 30% and had to go and change my son's diaper and returned to see that RAIDar had lost contact. Pinging is still working but frontview and RAIDar are dead. I dont see the NAS in 'attached devices' on the router either.

Kind of lost my way out of this so I would appreciate if someone with more expertise in this area could point me in an direction.

I hope it's ok to 'steal' a thread that is already resolved.

Thanks /Erik
