Sierra Wireless MC8805/DW5570 not working

I skipped how to change the usb comp if you do not have the serial ports exposed.

In Linux install "libqmi-utils". This will provide you qmicli.

Then, check the current usb comp

"sudo qmicli - p - d /dev/cdc-wdm0 - - dms-swi-get-usb-composition". Most of the times it's 14

Next, change it.

"sudo qmicli - p - d /dev/cdc-wdm0 - -dms-swi-set-usb-composition=6".

Now you can follow what I wrote. Also, do not forget to stop ModemManager before opening the serial port /dev/ttyUSB2

Thank you!! WWAN card is now prepared. I will test it in pfSense later.

@xt_ntwrk You're most welcome! Do not forget that this card it's not LTE, it's just HSPA+.

Ok, I see but for finding out the ugen* and cuaU* numbers
and also for connecting to the modem it is not so really relevant I think.

That's true but if you're going to the effort you might want to start with a device that's at least capable of the speeds you want.

HSPA+ might be fine here.

@dobby_ Yes, not relevant, but maybe @xt_ntwrk is not aware and he might get confused if his network operator is like mine, 4g LTE in B1 and B38. Also, on the MC8805 the sticker say 4G :).

Thanks for the remark. I saw that in some datasheet before. What i was not 100% aware of is that most (if not all) providers in Germany killed already the UMTS frequencies...

Do you have any other LTE or 5G card which you can recommend; which works fine with pfSense and is for mini-pci port?

@xt_ntwrk I currently do not have any alternatives. For me, this card would be sufficient if one of the 3 providers here still have something in the 2100 Mhz WCDMA. I will try with an Orange pre-paid card and see if it connects the packet switching part of the modem. Will post here the results. I need this card as a backup WAN. I have 500 MB bandwidth FTH for my main WAN connection.

However, I would go with the MC7304. I need a mini PCI-e card anyway, because that's what my hardware accepts.

I will post here the results with Orange. Maybe in a week or so...as time permits.
