A solid Power LED on the Bridge indicates that the Bridge is powered up but that it has not detected a LAN port yet. If the ‘Router’ LED does not start blinking a short while after the Bridge has been connected to a router, please check the following:
Check the Ethernet cable connecting the Bridge to the router. Make sure the cable is properly plugged in on both ends. Try a different Ethernet cable and/or a different LAN port for connecting the Bridge to your router.
Check if the LAN port is disabled. If the lights on the port do not light up when connecting a cable to it, the port is probably disabled and needs to be enabled in the router settings.
