AT&T Beam USB Cellular Modem Stuck in Airplane Mode
I tried installing an AT&T Beam 340u on a Surface Pro 4 running Wndows 10 64-bit but the device is stuck in airplane mode. The SP4 is not in airplane mode but the display on the Beam says it is. I checked AT&T All Access and saw that the option to Enable Flight Mode is unchecked and noted that I cannot check or uncheck the box. I installed the device and software using a local administrator account without errors but AT&T All Access is stating the the USB Modem is Disconnected even though Device Manager does in fact detect and list the device. I tried installing it on a different Windows 7 64-bit laptop with the same exact result and I am wondering if anyone has any suggestions on how to resolve. I already tried restarting and turning off all security software as well as reseating the SIM card but none of that worked.
