Hi All,
I have a old Huawaei USB Modem that I am using as a back connection on my pfSense setup at home. I have decided that I would like to upgrade to a 4G connection instead of a 3G connection for backup. I have run into the following in my pfSense logs and the connection for the 4G network never comes up.
Couple of questions, has anyone used the E3372-325 successfully on a pfSense box? Has anyone got any pointers on what might be going on here?

However the connection doesn't seam to ever connect to my 4G ISP. Just in case it is an ISP thing I am awaiting a SIM from another provider that I have tested with in the past on my older Huawei 3G modem so I'm hoping this might help in diagnostics.
Any pointers or suggestions are welcome, I am new to diagnose 3G/4G Modem issues so apologies if I have missed an obvious step.

What modem are you currently using that works?
When you plug in the E3372-325 what new entries are shown in the system log?

@stephenw10, apologies for the delay in replying.
So I below is an example from today what I see in the system log when plugging in the device;

Ok so it's detected as a USB Ethernet device and not as a USB serial port in the mode the modem is in.
Try assigning ue0 as a new interface and setting it as DHCP. See if it pulls a lease.

Hi, OK, so ue0 and assign the interface it does get a private IP. All good however access to the pfSense interface is intermittent untill I unplug the USB Modem is removed.
I may need to look into Changing the mode to Serial if possible. I will grab some logs System, routing and interface logs.
Ill post back shortly.

Make sure the IP it's giving you is not conflicting with any other subnet on the firewall.
