N300 Error message "No Ethernet cable is plugged into the Router Internet Port"

[Wanderboy]

My six month old N300 has unaccountably stopped connecting to the Internet. The lights are green and my computer and devices can see the N300, but there's no connection. I checked cable and plugs and eventually reset the modem but when I started the Netgear Genie I kept getting the error message mentioned in the title. I had made no changes of any kind to my modem or computer setup before this occurred. I'm using a wifi connection to computer (IMac) and devices. Can anyone help with this?

Hello wanderboy

Are you getting a IP address or can you ping the modem while connected via Ethernet?

Yes, IP address is 192.168.0.2 and I can ping the modem.

I can only suggest a couple more things to try like make sure your on the latest firmware and  try another ethernet cord use another port If you have tried that I would then attempt a factory reset. If the issue still happens it could be a hardware issue with the modem and if its still under warranty I would then contact netgear phone support.
