What's the version of the Reolink Client you installed on your computer? You may uninstall it and download the latest version from our official website and install to see whether it solves the problem.

You may change the ip address of the camera in Reolink Client into static. Or you may log into the administrative page of your router to do the address reservation for the camera. Then the ip address of camera can not be changed anymore.
