Old ReadyNAS won't move to new OS version

I figured out the problem: Under the Network tab, I clicked on setting for the network card and under IPv4, the Router was set to 1.1.1.1. When I set it to the address of my router it seemed to connect to the Internet. When I click on "Check for Updates" on the main page, it tells me the proper answer, that I have the latest version of the OS.

It's peculiar that this happened, because it had been working fine. But this problem never affected anything else on my network that I didn't worry about it. Nightly backups were always working properly. So, unless the problem comes back, I think I'm going to forget about it.

Now that two of my three problems are resolved (Yay!), I'll circle back to the simple question of Power-down or not. As I said the server is simply a backup for a newer NAS and because the data on that changes infrequently, the nightly backups take less that 10 minutes usually.

This old server has five drives in it, with a variety of ages (between 34 and 67 hours on them). If I had the funds I'd probably swap them out for three 8TB drives, but it doesn't seem to be a high priority.

So, any thoughts on Powering down for 21 or 22 hours/day or just keeping it running 24/7?

Thank you so much for your assistance
