Brume 2 does not Recognize WAN Cable

My Brume 2 which I just purchase does not currently recognize the Ethernet cable connected to the WAN port. If I switch the WAN port to LAN mode, it recognizes the cable; and I've tried several other cables beyond the stock one that comes with the device.

The device is connected to an AT&T Fiber internet Gateway - PACE 5268AC

The device is running 4.5.16 out of the box.

I am attaching the recent log file of the router. I'm not sure what I would need to do to resolve this issue.

Thank you.

if wan port is hardware broken. U can use the usb port, attach a USB Ethernet.

It's a brand new item out of the box. I'll sooner return it to Amazon.

You can swap the LAN and WAN ports:

If the WAN works on eth1 and not eth0, please let us know
