Dear @Chelsie_Judson
Did the module install in router from other manufacture？
It seems your current firmware is customized.
No, it’s just the development board. Does it have the latest firmware?
Dear @Chelsie_Judson
It is a customized firmware on our side, I can’t share the firmware.
Please contact with your provider and confirm if they have.
