Beryl GL-MT1300 with Netgear AirCard 320U 4G modem

Hi, I upgraded my GL-MT1300 from firmware version 3.216 to the latest 4.3.25. After the upgrade my AirCard 320U modem is no longer being detected. Status is "No Modem device found. Plug in your USB modem to start. "
Is it possible to get it to work? Or is the modem no longer supported/compatible?

Hi,

Please check the power supply problem.

Can you provide the system log?
