Hi Guys,

I have a client that needs to be setup using LTE SIM (Internal), and a USB Dongle for the second SIM.
the reason here is that we supply a maximum of 100GB of data per SIM, and they will require more.

The problem I have is that when the LTE Modem (Internal) is live, and the USB Dongle is connected (online, or not) the router will fail and reboot once the main LTE connection gets to 5 minutes, or very close to 5 minutes.

If I disable the internal LTE Modem, Enable WAN1, and the USB Dongle the system stays up, so it appears to be conflicting with the internal LTE Modem somehow, every 5 mins.

Any idea's would be helpful.

USB Modem Dongle used Huawei E3372 (Vodafone)

Thanks in advance.
