Router Archer C21 - TP-LINK

I took an Archer C21 router and when connecting a lan port it does not appear in the Genie ACS, and neither do the connected devices, there is no Hosts nor InternetGatewayDevice.LANDevice.1.LANEthernetInterfaceConfig. *, Even giving Refresh or Summon it does not appear, someone already had the same problem?
