I have a Raspberry pi0-2W on my home LAN on 192.168.0.100. It is working - as it has been for years. I'm having trouble setting up a second Rpi0-2W on the same LAN on 192.168.0.110
I set a fixed IP address with nmtui and reboot. I can log on with the new IP address but it can no longer resolve DNS calls, e.g. to google. And if I ping 192.168.0.1, its gateway, it just hangs.
This is what I've done:
For the second Rpi0-2W I loaded a new sd card with RpiOS trixie 64-bit using Rpi Imager v2.0.4.
Booted the pi, thenstopped with ^C.
So that's fine. Then:Then I log in with the new fixed IP address and ...if I Ctrl-C, it says e.g. There is a router connected to the ISP's modem (fiber) on 192.168.0.1
Another router, configured as an access point, is connected to the first router via a switch and is on 192.168.0.239
Both of the Rpi0-2Ws are connected to the access point, as the main router is out of WiFi range.
I have taken everything on the LAN down, and restarted one by one from the ISP's modem onwards.
I have several Rpis on this LAN on both bookworm and trixie, all working, with fixed IP addresses.
I've done so little since a clean install, just the nmtui and I can't see what I've done wrong.
I've run nmtui on the old pi0 2W to compare the setting and they are the same except for the IP address.
Any suggestions, please?
