RN212 can't seen by time machine anymore
Dear forum experts, my RN 212 vers. 6.10.10 run flawless for a long time... Raidar vers. 6.5.0 can still see the NAS and tell me everything OK, aka two green light for the two 4TB disc bays. ...

I‘ve checked right now.
The name of the NAS is READYNAS and the IP Adress is xxx.111
Raidar reported the same IP Address.
In the NAS admin pages under network and IPv4 reads the boxes from top:
static
IP xxx.111
subnetmask 255.xxxx
router xxx.0.1
DNS- Server is cloudflare
And i didn’t have a clue, why the time machine didn’t see the NAS anymore?
I have no more time now and will come back to the topic at a later point in time.
Thank you for your assistance and advice

One possibility is that the Mac was connecting to the NAS IP (not the hostname) and that the old router didn't use the 10.0.0.x subnet.
But that assumes that the NAS is connected to the router (not a direct ethernet connection between the Mac and the NAS). Is that the case?

I am confused here, as before you said the NAS was using DHCP - not static. Did you change it? If so, why?
Generally I recommend using DHCP on the NAS and reserving the IP address in the router. That makes it easier to switch to a new router, and also avoids accidentally setting up a duplicate address.
Why is the DNS server set to 10.0.0.138? That isn't CloudFlare.
FWIW, private IP addresses aren't routable over the internet, so it is safe to post them. My primary NAS is 10.0.0.15 and the subnet is set to 255.255.255.0 - knowing that won't help you connect to it.

sorry for the confusion created,
as i mentioned before, it’s years since i set up the READYNAS and didn’t care about it…up to now, when the TimeMachine couldn’t find it anymore.
I checked the wires:
The NAS is connected to a switch, where the iMac is wired to as well.
in the NAS network settings i tried with DHCP as well as without?
Now with DHCP the NAS changed IP from xxx.111 to xxx.109
and the router IP in the box below reads now xxx. 68.1
Raidar sees the NAS now also with the IP xxx.68.108
The iMac has Ip xxx.68.104
Does this to you make any sense?
Thank you for your interest in my problem!

The iMac has Ip xxx.68.104Ok. Again, it is ok to post the full addresses. I am thinking that the DNS also changed - either to the router IP or Cloudflare (1.1.1.1). Did that also change?
I am guessing that the WiFi 7 mesh is serving as your router (that you did not set it up as an access point). Is that the case?
