GL-X750 LTE not served to LAN ports

X750 with latest GL-Inet release firmware. AT&T LTE sim installed. Wi-Fi works as expected. LAN ports are assigned IP addresses but have no access to the internet.
Installed LUCi.

Network>Interfaces>LAN Br0 shows the Cellular Modem as the gateway for all items in the LAN Br0.

I have two of these devices both perform the same. Looking for a clue on how to pass traffic from the ethernet ports to the cellular WAN.

It appears the Captive Portal is still active even though the toggle is disabled.

Very strange, did you configure the LTE connection in luci?
