Connection issues

Hi, I have two cameras set-up (have done for nearly a year now) the first is a battery spot light located at the front, the other is a mains flood light at the rear. The rear is able to connect to the WiFi (Yet it’s furthest away from router), yet the front will not. I’ve gone through the settings over and over yet the device will not connect. When trying to join the Ring WiFi it fails to show, subsequently the device keeps highlighting (unable to join). The battery ran out, I’ve recharged it and now I’m having no luck at all, please can you help?
