Receiver Offline and Cannot access Interface Page

Hi everyone , i have just changed my Normal Internet to Fibre Optical
Network.A new Modem Router has been assigned to me and now when i
connected the FR24 box to my LAN HUB switch , i cannot find its IP,
even with an IP scanner and nor can i access the interface page. I need someone which can help me resolve this through
TeamViewer . And , Receiver appears OFFLINE on my STATS Page .:(
