Have just purchased above unit and it will not recognise my NBN satellite modem. Hook it up as per instructions and keeps saying no internet connection even though light on router shows internet connected.Cables are fine, internet is working. Have turned units off and back on and makes no difference. My PC when hooked up direct to modem all good. When I hook up router and then PC through router nothing. Wireless is working fine. Old netgear router never had an issue . Hooked up and away we went. Unfortunately this has died, so went to this router. Any clues?
