Network consists of the following: [provider modem] > [home router] > [devices]
IPs are assigned on the home router, and the NAS allows assigning the IP for NAS.
This setup has been working well for over a year.
Changed providers, so [provider modem] was swapped w/the new provider.
After this change, my NAS IP changed. Double checked [home router] and [devices/nas] and IPs are still as assigned. Problem has been happening for about a week… all equipment restarted muliple times. Leases renewed. Even powered everything down for 5 minutes and started everything up again, trying different sequence orders for devices powering up.
[provider modem] is basically bridged to [home router]
[provider modem] has little if any settings to manage (which was the case for previous and is the case current provider modems.)
Why does the router assign a dynamic IP address to the NAS at all (even if it is configured to theoretically always get the same address)? Any particular reason you have it set up like that?
Set the NAS to a fixed IP address on your network but outside the router’s DHCP range so you can be sure it will always have the same IP.
I am clearly making a guess. The only change made was swap of the modem. Modem only feeds the router and router handles everything else.
Finding it odd myself, and had no issues since the start. The NAS ip changed by one digit (one number lower than normal.)
“Set the NAS to a fixed IP address on your network but outside the router’s DHCP range so you can be sure it will always have the same IP.” Excellent idea worth learning and trying

Why is the network set up that way?
Had many configurations over the years and found this to be the most straight forward, manageable, consistent, reliable.
In addition, other factors such as the router (linksys) has no way to backup configuration files/data…zero. (yes, it is true and verified countless times w/linkysis) so a right PIA if ever forced to start over. The new service provider provides the modem w/only basic function…no way to even assign an IP for example…so need the router anyway.
