Spotlight Cam Pro Plug-In - powerline

Hi everyone!The wifi connection to my Spotlight Cam Pro Plug-In wasn't great so i bought a tp-link extender but it didn't help. So i bought the TP-Link AV1300 Gigabit Passthrough Powerline ac Wi-Fi and after setting up saw the signal strength at the ring change from a red 78 to a green 50 - happy days. The signal today is now back in the 70's. I get a good signal with my phone by the camera (by the garage) but it seems the ring isn't connecting to the powerline adaptor.Has anyone else had an issue like this?Many thanks 😊
