Nighthawk M1 no Ethernet

[Tdblanchard]

We had our M1’s IMEI flashed by someone in order to get an unlimited AT&T data plan to work.
I finally got around to hooking it up at the farm house where we intend on using it yesterday (very rural).
One issue I was having was connecting an AC1750 router to the ethernet port.
I was able to determine that the ethernet port wasn't functioning at all.
I unfortunately had to reset the M1 to its factory settings because I turned off the wireless radio prior to learning the ethernet port wasn't functioning.
It's back up and running now (40mbps down / 20mbps up!!) but I still can't get that darn ethernet port to work.
Is there something I'm missing?
Did the IMEI flash render the Ethernet port inoperable?

If it is the corporate model (MR1100ABS-...), the ethernet ports don't work.

Not sure what you are trying to do?

Sounds like you are going to use the M1 as a modem ONLY and connect it to another router.
If so you need to put it into passthrough mode.

Note: this disables the WiFi. Will need to connect an ethernet cable and use the M1, IP address
to enter back into the setup.

Will also need to have the M1, DHCP server off
