4.5 deleted NAS! Vulnerability not fixed!

Yes, it should be added back. It's just meeting some technical difficulties right now.

Also, to be clear, it's just file sharing/network storage, we shouldn't have advertised a NAS. After all, SD cards can't do raid disaster recovery.

The version that fixes it is in the final stages of testing. They are 4.3.17 and 4.5.17.

But I don't think the E750 has been released with 4.5.x firmware.So it is 4.3.17. You can find it in BETA:

How did you upgrade to 4.5?
