I have a HD-H 1.0TGL/R5 Terastation and I updated the firmware from 1.2 to 2.16. I cannot access it from the network, it has a static ip address. When I access it with the navigator it tells me it is in EM mode. All leds are normal and it seems to be working fine. The navigator gives me the error, em was detected, update firmware or contact your local technical support. All the information on the navigator is correct, ip, network, gateway, etc.
