RING VIDEO DOOR BELL WHITE LIGHT NOT TURNING AND NOT CONNECTING TO WIFI

Hello everyone. Does anyone know an electrician (or specialist) that could come and check why my RING video door bell is not working. It worked originally and then I had it replaced when it stopped working. My internet then went off for a while. The new one will not work and I was told by RING support that it would work when my internet was was replaced . The internet has been working for some time now but the doorbell will not connect. I have tried charging it .
