To resolve this issue, we recommend disabling DHCP and operating in Static IP mode.
As you mentioned, if the IP address changes back after a reset, this is most likely because the device is currently operating in DHCP mode.
Please also check whether the two modules have the same MAC address. If they are running in DHCP mode with identical MAC addresses, the DHCP server may recognize them as the same device, which could cause an IP conflict. (Although this case is rare, it is worth verifying.)
While receiving IPs correctly from the DHCP server may reduce such issues, the most reliable method is to use Static IP mode with fixed addresses.
