6-3-4 pattern green blinking on Connect ME

Hello,
I have a Connect ME, and when I turn it on it starts to blink the green light on a 3-4-6 pattern. When I plug the ethernet cable, I am unable to detect it on the router. The light on the router is on, but I get no IP. I tried to a hard reset but did not work.

What could it be?

Best regards

There is a troubleshooting guide in the Knowledgebase link is below: I am assuming this is a ConnectME PlugNPlay

LED blinking patterns are on page#135 of the Digi Connect’s user’s manuals.
