      Yes, switching the mode in something else might be easiest.

      Ok. I don't want to disassemble the box, since its 24/6,5 needed. This will take some time until I get another (external) Quectel Card of the same type to "fiddle" around with. I will post the results here.

      Many thanks for your time, ideas and help!

      Best Regards

        Do you get an AT prompt on any other com port? It could be one allows setting values.

          Oh yes! I tried all of them (also on the pfSenses GUI to establish a ppp IF), but the ttyu0.3 and cuaU0.3 operate like my historic ZyXel 19k2 landline Modem and its predecessors (Proper Output w/ CR/LF) on the (ssh-) command line/console.

            Was one of my idea too :-) - Since the AT Commands documentation from Quectel lacks quite a bit on infos . "AT+QCFG="usbnet", x" isn't explained and not listed in the output of "AT+QCFG=?", but the firmware presents that option, wich is explained in the OpenWRT forum like this:

            AT+QCFG=“usbnet”,0 < QMI/PPP/Default (??? - Not in my humble oppinion)
            AT+QCFG=“usbnet”,1 < ECM (seems to be the default with Revision: EP06ELAR03A08M4G)
            AT+QCFG=“usbnet”,2 < MBIM

            The 0.3 allows me to set any other settings like this:
            AT+CFUN=1,1 (reset/reboot the card)
            OK
            or
            AT+QCFG="volte_disable",1 (self explaining)
            OK
            or
            AT+IPR=921600 (set "line"-Speed)
            OK

            But not this one at tty/cua 0.0-3 :
            AT+QCFG=“usbnet”,0
            ERROR
            Tested anew on ttyU0/cuaU0 - Results:
            On .0 - No response w/ AT+QCFG=“usbnet”,0
            On .1 - No response w/ AT+QCFG=“usbnet”,0
            On .2 - error w/ AT+QCFG=“usbnet”,0
            On .3 - error w/ AT+QCFG=“usbnet”,0

              You do have an alternate interface descriptor on interface 5. You could try setting it:
              usbconfig -d ugen0.2 -i 5 set_alt 1

              I don't really expect that to work TBH. It will probably just refuse as the interface is in use.

                Hi Everyone! Hello Steve!!

                Finally I got that Quectel EP06-E running in PPP-Mode WITHOUT having a dynamic MAC ueX Ethernet interface.

                Preamble: The cuaU Device which is held by the Modem-Card depends on your Hardware!! The named one here is only for Reference!!

                Steps:

                Connect (ssh) to the pfSense box, get a shell (option 8), and open the LTE cards AT-Interface via a serial link & cu

                cu -l /dev/cuaU0.3 -s 115200 -> serial connection to the Modem-Card w/ 115200 baud

                This "linespeed" is imho mandatory since other modes seem to "eat" typed or pasted characters, which was one of my faults here!
                Anyway: AVOID, if possible, to copy and paste AT Commands, the Card (imho) might missinterpret that command and responses w/ an error.

                Set the cards "usbnet" mode 2 and fix the "serial"-linespeed of that Card!

                AT+QCFG=“usbnet”,2

                1. Write the config to the Card

                AT&W

                1. soft reboot the LTE-Card to activate the changes (no (hard-)reboot of the whole box necessary)

                AT+CFUN=1,1

                "cu" will close and you are back on the shellprompt after a while.

                1. Create a PPP IF on the GUI.
                  Parameters depend on your Cell-Provider-Plan to communicate w/ this Quectel device.
                  BUT: pfSense here awaits a linespeed of 115200 (baud) to sqawk to the Modem-Card.
                  This should be forced w/ the advanced settings at the ppp-IF page:

                Init String +IPR=115200

                1. Assign that newly build ppp-If to an OPT-Interface on your box

                That will do - I Hope ;-) - Its working for me, but maybe not perfectly described.

                Addendum:
                Possible "usbnet" Modes are:
                AT+QCFG=“usbnet”,0 < Default
                AT+QCFG=“usbnet”,1 < USB Ethernet IF,* w/ dhcp Server active on the Card. Typically w/ IP 192.168.225.xxx/24, GW 192.168.225.1
                AT+QCFG=“usbnet”,2 < PPP IF via /dev/cuaU0.3

                *W/ an auto generated MAC Address on ueX which changes the NID as in the Topic!

                Last but not least:
                Any suggestions, critic and so on are welcome!
                And also many Thanks to Steve for accompany, ideas and help w/ this topic!!


                Any typos and syntactic errors found here, can be kept by the finder ;-)

                  Ah, nice. So it was just the console doing something funy at a different baud rate? Nice catch!

                    Seems to be that 😊 and the pfSense software itself, because of the Baud-Rate while initiating the communication w/ the Card.
                    Are there any options to change that to a lower or higher rate (i.E. to 921600 Baud -> AT+IPR=921600)? I would like to check that out and measure the troughput w/ different rates ...

                    Anyway: One more USB/mPCIE Card which can be listed in the docs, I hope. ☺

                      The actual throughput is not limited by the ppp baud rate, you should see a lot more than 115kbps!

                      I usually see ~30Mbps here on the Sierra modems. Pretty good signal area. I've seen reports of other getting ~60Mbps.

                        OK. Guess I was too much in my "landline modem times" from the 80ties w/ the AT-Commands 😊 🙃

                        The Gateway Monitoring ping-Times (public IP Address from within the Providers Network) and the RTT aren't really different from the other Mode.
                        So its OK to me. I haven't measured the rates since my external Yagi-Antennas will move to a better place in a few weeks.
                        Much more important for me was to prevent the change of the NDI.
                        (BTW: Can someone change the Topic to the correct abbreviation...??)

                        Even if the performance will not reach the old mode: I can only die one dead. 🙄

                              After all, the Modem will respond to " AT+QCFG="usbnet",? "
