How to make automatic change of dynamic ip (when gray appears) to white?

Question

Computer networks

There is a TP-LINK TL-WR841N router Dynamic IP is connected. But when changing the auto IP, sometimes a gray IP comes across and it cannot be accessed from the network. You have to reboot the router until the white IP appears, but the reboot wastes a lot of time. Is it possible somehow automatically on the router or through scripts on the PC to change the IP when access to it is lost via ddns?
--At the moment there is no way to connect a static IP, so I'm looking for a way to auto-replace.

. This is a clear configuration problem. No need to invent a crutch, torture the provider.

It's stupid in itself, unless you put dd-wrt on it.
