New LM1200 not working

[nickbrowns]

I have recently bought a new LM1200-100NAS, When I when connects boardband to the WAN port and the router to the LAN port, the device does not recognize the broadband connection. It only runs off of the AT&T LTE network. I am using LinkSys MR8300.

I was expecting a latest firmware, but when I check the LM1200 Manager page, it shows me an error in updating the device. Try again. The device has factory settings I made a change in LAN--> Operation mode to Bridge. I have restarted the device but no luck. Should I reset my device or if anyone else has a better solution please do recommend....

If its just the lm1200, does it connect and work with devices?
