MAX BR1 "obtaining IP address"

I am not able to connect and obtain an IP address.

I was able to connect no problem at my home in Chandler, AZ. I am now on the Navajo Nation and no go. I have a strong signal and both my Verizon phones connect. I have tried the following:

upgrade firmware (6.3.5)
changed the APN (manual and auto)
toggled roaming
rebooting several times.
