Searching for downstream signal or NTD has no power

NTD has no power, check cables or try another power point If the lights indicate all is working there could be an issue with your router – please contact Pentanet if you do not have internet access.The UNI-D1 port on the back of the NTD has Link lights to indicate cable connection to a computer or router – this can be Green (1Gbps Link) or Yellow (10/100Mbps Link) depending on the age and quality of the Ethernet cable you have or the router connected – If no Link lights are on, the cable needs to be replaced completely or there’s an issue with the router.This is a self-test and no action is needed The Downstream, Upstream and Online lights will all flash briefly when the NTD is powered on.No action is needed - simply wait for the update to complete If both Downstream and Upstream lights are flashing and the Online light is on, a firmware update is in progress.If both the Downstream and Upstream lights are flashing but the online light is off, there is no connection to the NBN network.

4 Lights from the top to bottom are Power, Downstream, Upstream and Online.If you're trying to connect for the first time or suspect that you may have lost internet connection the lights on your NTD or NCD can often be a good indicator of what's happening with your service. Some NBN technologies use a Network Termination Device (NTD) or Network Connection Device (NCD) in order to deliver the connection to the router in your home.
