pfSense 2.4.5 with Sierra MC7710 wireless issues

jpdsc

@stephenw10 Hello! Thank you for your reply. I received the modem and the USB PID is 68A2 which indicates QMI.
I am able to switch it using:

AT!ENTERCND="A710"
AT!UDPID=68A3
AT!RESET

However, the USB is recognized but the modem isn't. I don't see any cuaU* or cuau*. Only cuau0.

ugen0.3: <Sierra Wireless, Incorporated MC7710> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (0mA)

Should I add loader_delay="40" to /boot/loader.conf to give it more time to initiate?

Thank you for your help.

Does it have a 'composition'? That's usually what you need to change to get a different mode. I've not tried that particular modem though.

AT!USBCOMP?

@stephenw10 The issue is that I cannot cu into the modem to use the AT commands. Is there a reason why cuau* isn't showing in /dev/? With the other modem it was showing fine.

Or am I seeing this wrong?

stephenw10

Because in QMI mode (composition) the modem does not present any AT interfaces for the serial driver to attach to. You need to chnage the USB composition to one that does.

How did you run the above AT commands?

@stephenw10 Clear.
I didn't run the AT command. This should be ran using cu to the /dev/cuau* right? Is there any other way to run it or do I need to get an external enclosure to the software from Sierra and convert it from QMI to DIP?

stephenw10

You have to do it from Linux or Windows because FreeBSD has no MBIM or QMI drivers to access it.

How did you do that? Or was that just what you were planning to do?

Be sure your modem is detected

A device such a modem is normally creating 4 ports

My Sierra Wireless MC7710 will be able to connect under the following port (in console), but you must perhaps try
out some ports to get success with that.

[23.01-RELEASE][root@xx xx xx]/root: cu -s 9600 -l /dev/cuaU0.3
Connected

Be sure you choose a cuaU port and not a cuau,
because the great U is standing for USB and normally
this will be way how your miniPCIe modem will be
connected to your pfSense. After seeing the "connected"
you will be able to set up the AT commands for your modem.

Alternative:

miniPCIe to USB convertor
Windows PC
insert the modem and don´t forget to connect the antennas for a proper grounding!
Search the internet for a Sierra Wireless QMI to DIP
software and change it there a little bit faster but not
for some money (convertor).

@dobby_ and @stephenw10 Thank you very much for your assistance and replies!

I have decided to order mpci-e to USB enclosure to change from QMI to DIP on Windows.
I saw some people did this using WindowsToGo USB but I don't want to risk this so I'll just do it though the adapter.

Thanks again!

stephenw10

Make sure it's one that is wired for USB. Some will be PCIe only. If it has a SIM slot it will be designed for modems so should be fine.

@stephenw10 I received the USB enclosure, installed Windows Drivers and use the BZ31018_DIP_QMI_ModeSwitch tool . Everything is working as intended!!!

Thanks all for the help.

Additional info below in case any else has the same issue.

Modem model: MC7710
USB enclosure used: TBD, AliExpress site not working
Windows drivers: GenericDriverSetup_5087.exe from the Sierra website
