Nighthawk M1 Ethernet Port Timeout

I kind of abandoned this question a while back as we didn't get much of a response for a few months. Glad to see people are getting some benefit out of it.

We ended up instructing our site guys to press the button twice during startup. From this point forward the port remained up until the connected firewall was restarted.

At some point during last year (Aug 2017), version 10.16.04.04 was released to Telstra customers. This meant the port came online during the initial power on and the button no longer needed to be pressed during startup. We could also reboot our firewalls without having the port go down. The port will still, however, timeout after a period of time when nothing is connected to the LAN port. I checked a couple of spare routers we have sitting here for later versions but they still doesn't get anything beyond this point. So, the fact that people are saying there are newer versions, I assume that some have been withdrawn or the update process doesn't really work properly...

Logging in now, I realised that I was contacted by Netgear in Dec 2017 with an offer to beta test via PM. From the comments it looks like the full release is about to come out anyway, so I'll wait to see what happens.

I hope this post helps some people understand what our experience across about 10 devices. If you are in urgent need of a fix, perhaps contact Netgear support as there is a beta available.
