I have a Pepwave MAX BR1 (HW2) using both AT&T and Verizon sims. The Verizon sim works fine with no issues. The AT&T sim sometimes has problems connecting. Even with a strong signal, it sometimes hangs up with the never-ending message “Obtaining IP Address”. Right now, I’m parked in Death Valley. I have a strong AT&T (3G) signal. The Pepwave is stuck “Obtaining IP Address” and simply will not connect. I’ve tried various iterations of connection settings: Network mode Auto or AT&T only; LTE/3G Auto or 3G only (since I currently have only a 3G source); Operator setting Auto or Custom -> broadband. I’ve tried rebooting and factory router reset. I’ve also upgraded to firmware 7.0.0. Nothing seems to work.
The funny thing is that AT&T works fine in many, if not most places. The same AT&T sim also works fine here in my iPhone. Is there something that I am missing? Any advice would be greatly appreciated!
