Model: Deco M5  
Hardware Version:
Firmware Version: 1.5.7 Build 20210819 Rel. 43499

Hi,

For some reason, the LAN IP for my main Deco changed from 192.168.1.1 to 192.168.4.1   

I really don't know how this happened.

 

Now, I want to change it back to 192.168.1.1 but if I want to store this address, I get a message "Storing the settings failed, please try again later" (or similar).


What can I do?

Hi, Did you have any Raspberry Pi-Hole in the LAN network, and it was set up as the WAN DNS server?

If yes, the IP conflict here might trigger the change of IP address.

So it is suggested to set up Pi-hole as the LAN DNS: How to use Pi-Hole DNS Server on TP-Link routers?

 

And It requires connecting to the Deco’s Wi-Fi to change the LAN IP settings.

So please make sure the smartphone is on the local network, not over 4G mobile network.

Thank you very much and wait for your reply.

This was it, thank you. It was incorrectly setup by myself but I'm a bit suprised that the Deco can change such a crucial parameter without noticing, it has previously been working for about six months without any problem.
