ReadyNAS Pro 4 [X-RAID2] looses connection to LAN repeatedly after update to RAIDiator 4.2.31

Question

My Ready NAS Pro 4 looses accessability from the local LAN on transfer of larger amounts of data. A factory reset did not solve the problem. Restoring data from an USB-Disk works.

My ReadyNAS Pro 4 ist connected to my LAN via a Netgear WNR 3500L just used as a switch, the router and DNS-server is a Maipu-Modem. This configuration worked quite well for 2 years. About four or five month ago my NAS startet to loose connection to the LAN in an increasing frequency. The only way to reconnect the NAS is to manually shut it down and restart it. Update to firmware RAIDiator 4.2.31 did not help, but made the situation even worse. The ReadyNAS stays connected for even days when there is only small data traffic. Copying larger amounts of data (like an amount > 2 GB pictures from a camera storage card) will work for a while (some minutes) and then suddenly the NAS will hide, so that the connection is lost and data transfer is interrupted. Not even the admin-account of the NAS can be reached or connected then unless the NAS is manually shut down (power off) and restarted.

There are no further apps installed or used on the NAS.

I've already posted this topic once, but factory reset did not help. Can anyone help me? I'm just a basic user with no great experience in setting up networks or things like that. So please explain on a very basic level for me.

The next time it happens, can you try disconnecting the ethernet cable from the NAS, and then reconnecting it?&nbsp; You should then see the IP address show up again on the NAS LCD display.&nbsp; Then try accessing the NAS again (without rebooting).

Hello,&nbsp;I tried it, but this does not work. When the NAS gets inaccessible the IP-Adress remains displayed, only when disconnecting the LAN-cable it says, that there is no LAN connected. After dis- and reconnecting the IP-Adress ist shown again.A fixed IP4-adress is assigned to the NAS by the router by using the MAC-adress of the NAS. The same IP4-adress is&nbsp;filled in as a value in the NAS setup menue.Only powering the NAS off and switching it on again makes the NAS accessible again.&nbsp;

Can you confirmed that you did a factory reset (destroying your data), and that didn't help?&nbsp; Or did you actually do an OS reinstall (which does not destroy your data)?
&nbsp;
Also did you try the second NIC port on the Pro?

- Can you confirmed that you did a factory reset (destroying your data), and that didn't help? Hello StephenB: I definitely did a factory reset triggered from the settings-menue of the admin account. I had to type in "FACTORY" to confirm the reset. All data, settings and shares were deleted or reset. The NAS was accessible after the reset without any further problems. The available disk space was appoximately 10 GB smaller after the reset (snapshot function reseving 10 GB of data space was switched on before and after reset). You told me problems could result from a full operating partition, that's why I performed the factory reset. - Or did you actually do an OS reinstall (which does not destroy your data)? I faced some troubles to reinstall the OS, actually I failed to do so. I tried to reinstall the OS, as I suspected the update toRAIDiator 4.2.31 had some troubles, but any further attempt to reinstall the OS was refused, as the system told me that this already is the accurate version of the OS. So how to reinstall the OS by the way? - Also did you try the second NIC port on the Pro? This is defintely worth a try!

Thx, I wanted to make sure I didn't send you in circles.&nbsp; The NIC ports often fail together, but it is worth trying.&nbsp; There are some issues that only show up on one port (connector problems for instance).
