Hi @rsovero,

Please unplug your gatway’s power cable and wait about 30 seconds then plug it again. After gateway power up, please check radio firmware version again.

In case your gateway does not automatically select ATT radio firmware, please follow the document below for manually selecting the radio module firmware on page 354.
