Nighthawk M1- Ethernet Port

I'm not sure of all the details but there is something restrictive about the way the ethernet is set up at Telstras end. Ive been trying to get a simlar set up to yours running and it just won't work. I asked Netgear and they said to ask Telstra as the modem is set up to their standards. I've found that talking anyone at Telstra who has any real clue as to what or why it doesn't want to play ball via ethernet is, so far, impossible. Ethernet wont function with a splitter port or any consloes even when directly connected. I've found I can only connect to the internet via ethernet directly to a PC (Mac) and even then it seemed to take a few goes to connect....
