4G/LTE USB modem

@rajil.s - when you restart pfsense and disconnect/reconnect the device, does pfsense throw up the missing interface?
I dont expect it to work if you unplug the usb modem and put it back. However, I do expect to work if the pfsense router is rebooted.[DOUBLEPOST=1532201643][/DOUBLEPOST]I decided to upgrade to E3372h-607_UPDATE_21.200.07.00.00.BIN from here since there was an issue with internet. Out of the box the device is set to

Code:
AT^SETPORT?
^SETPORT:A1,A2;12,1,16,A1,A2                               
                     
OK

I changed it to,
Code:
AT^SETPORT="FF;10,12,16"

The init string in PPP connection had to be modified to, &F&C1&D2E0S0=0

It comes up fine in pfsense now.

@vivek.krishnan After a reboot of the pfsense router, the connection came back up. Ofcourse if you take out the dongle and put it back the device would come up on a different USB address, so it wont work. In FreeBSD it is possible to give a fixed name to a USB device (udev rule in linux). So instead of using /dev/cuaU0.0, you could use /dev/modem. Whether that interface actually shows up in pfsense GUI is another question.

Under linux, the NCM driver can be turned on by using,
Code:
$echo -e "AT^NDISDUP=1,1,\"TypeYourAPN\"\r" > /dev/ttyUSB1
$dhclient wwan0

I was able to get this modem working in NCM mode in FreeBSD 11.2. Sadly, NCM is not available is not available in pfSense (stable based on 11.1). The slower PPP mode works fine though as demonstrated above. I guess NCM should be available in pfSense 2.4.4 which is based on 11.2.

@vivek.krishnan There are LTE B3/B5 mini-pcie card available here. Dont see anything on B40 though.

----------------------------
Tried pfSense 2.4.4 snapshot in a VM and NCM works!. The APN needs to passed manually though,

Code:
echo 'AT ^ NDISDUP = 1,1, "yourAPN"' > /dev/cuaU0.1

The above could be stuck in /etc/rc.local.
