ReadyNAS202 is not connecting to the network
My ReadyNAS 202 has suddenly stopped showing up on the network at the assigned IP address. Almost everything on the device, including the main ethernet port activity lights appears to show things working as expected. The one exception is that the secondary ethernet port shows two solid green lights even though nothing is plugged in (given I never see the back of the device I have no idea if this is something new or just normal).
I've done some reading here in regard to similar issues but it all seems very complicated, and further the RAIDar software often mentioned will not install on my Windows laptop as it can't find Java even though I have Java 17 installed.
As the device is nearly 8 years old I'm willing to accept it may be time to buy a new one, but I need to know how to migrate my existing data to a new system. I had the same problem 8 years ago when my MyBookWorld NAS failed in the same way (lost network access) and it was extremely painful migrating to the ReadyNAS 202.
Unfortunately I'm not even sure how my ReadyNAS is configured in detail - it has 2 disks and I expect I accepted the default RAID configuration. The disks are 2TB Western Digitaln3.5" 7200rpm SATA drives.
Any advice/suggestions greatly appreciated.
Thanks,
David

Have you tried moving the ethernet cable to the secondary port?
Also, have you tried rebooting the NAS? The clean shutdown procedure from the front panel is on pages 35-37 here:

Then it is RAID-1 (linux software raid, using mdadm), and using the BTRFS file system.
Thanks for the response Stephen.

I can obtain various JRE versions, but note RAIDar states it needs at least JRE 11 - hence I expected 17 to be fine.

Yes

Of course, many times.

Thanks. That rings a bell from when I had to do recovery from the MyBookWorld NAS.

Netgear hasn't maintained RAIDar. The JRE I posted works with RAIDar 6.5 (and everything newer I've located will not).

I'd like to see if RAIDar can find it.
If it doesn't, then power down and remove the disks (labeling by slot, so you can return them to the same bays later). Then power up diskless, and see if RAIDar finds them with a no-disks status.
Make sure the NAS is powered down before adding back the disks.
