ReadyNAS Duo v1 NIC failure?
Hi there I have a ReadyNAS Duo v1 with 2x2TB drives. I have been unable to connect to it for a week or so.... and I have tried: - - connecting it to 2 different routers and different ports on t...

Let's start with this. If you have a USB adapter/dock you can power down the NAS and connect disk 1 of the NAS to a Windows PC. Then use R-linux for Windows to offload the data. https://www.r-studio.com/free-linux-recovery/

If there is no damage to the RAID array on the disk this is possible. If the firmware on the "new" chassis isn't the same as what is installed on the disks, then the "new" system will install whatever firmware it is running onto the disks when you boot it up. It would be good to avoid this (or at least eliminate the possibility that you are downgrading firmware).
So the first thing to do is get a scratch disk (not from the array), install it in the new Duo, and let it set up. After that, install the same version of firmware that was on the "old" Duo. If you don't know the firmware, install 4.1.16.
Note that if the working Duo runs 5.x.x firmware or 4.2.x firmware, then it isn't a Duo v1, and it can't be used for recovery.
After installing the firmware, power down, remove the scratch disk, and put disk 2 of the array into slot 2. Power up using the boot menu to skip the volume check, as you don't want the system to attempt to repair any damage (as it could result in data loss). See pages 15-16 here: http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf
I'm suggesting disk 2 because
(a) it preserves one of the disks for other possible recovery attempts
(b) RAID recovery software and R-linux for Windows have trouble with the Duo v1's "parity" disk - which is usually disk 2. So it's best to preserve disk 1.

2. Would it be better to take the NIC out of the working device and put it the old one?
I wouldn't do that. If you find after data recovery that the "working" device isn't quite working, then you could try it I guess.
