I have ordered a Dell version of the EM7455 along with an m.2 to USB adapter and would like to use it as a backup WAN interface in PFSense 2.3.2 (current stable release based on FreeBSD 10.3 kernel).
I came across a thread in the PFSense forums (forum.pfsense.org/index.php?topic=96468.0) which indicate the MC73xx modules weren’t working yet on on PFSense 2.2.3 so their solution was to change the device PID/VID to ones that were supported since the firmware wasn’t all that different from some of the older modules. I realize that isn’t a true solution and ideally appropriate driver support would have to be written into FreeBSD as a proper resolution. However, I cannot find anything that would indicate proper FreeBSD drivers were ever added for MC73xx or MC/EM7455 since the time the PFSense thread was authored (2015).
My question is this: is there anyone out there running the EM74xx under FreeBSD/PFSense and if so, how is it configured? I keep reading a lot of different setups under OpenWRT some using PPP, QMI, MBIM, etc. All I want is to be able to connect the Dell EM7455 to my local provider (T-Mobile) and use it as a defined WAN interface in PFSense whilst achieving true LTE speeds (not the 25Mbps limit that exists using PPP).
My current low-cost setup for backup WAN in PFSense is using EasyTether running on an Android phone connected via USB to the router (WAN is the tap0 interface as configured by the EasyTether client in FreeBSD). The downside of this setup is the double NAT and random loss of throughput / stability. The connection is essentially tunneled through ADB packets in Android so I would like to avoid all the “middle men” and allow FreeBSD to directly interface with an LTE modem (EM7455 in this case).
Thanks to anyone who reads this and cares to offer any help.
