USB D-Link DWM-222 4G stick with RBM33G?

RouterOS Beginner Basics

Hey there-I have a D-Link DWM-222 4G stick that I’d (ideally) like to use with my RBM33G. I already have one LTE card inserted which I’ll be using for one connection, but I’d ideally like to double up and have redundant/load-shared connections over the two. I can’t, however, seem to get it to work. It never shows up in the USB list and the instructions I found here https://lukas.dzunko.sk/index.php/Mikrotik:_D-Link_DWM-222 don’t appear to help.

I had a similar issue in PFSense where this modem would only register itself as a USB device upon insertion and had to be flipped to modem mode, something we weren’t able to accomplish there but I’m hoping to do so here. I tried to force the mode but that didn’t work:

 1          serial1                                                                                           1                                                                                            auto

Is there any other way to force a USB mode switch? Like an installed package or something?

ROS 6.47 ?
show system \ resources \ usb list
you should see the usb1 interface !

System \ Ports \ Firmware button :
Ignore DirectIP = Ignore LTE => yes, then you see your usb1 interface and you can use ppp-out connection
Ignore DirectIP = Ignore LTE => no, then you see your lte1 interface and you can use dhcp-client on it.
After change that option System \ Reboot !

I don’t know if your device works in ECM mode (lte1) or PPP (usb1) - you discover it via checking upper lines.

2 1-2 is my existing 4G integrated PCIe card
3 1-1 is the USB modem

But if I shut off the LTE then my 4G card will also need to be switched over to PPP too, yes? (I currently have it on LTE1)

I did just shut it off and my integrated modem and LTE1 are still functioning-let me see if I can make this work…

I don’t know what to write you.
You should have IgnoreDirectIP=No because you have r11e-lte-4g module.

This modem can works as ECM/QMI/MBIM, then your both lte device will be work as lte1 & lte2 interface and this should be your target.
I think QMI can work base at https://osmocom.org/projects/quectel-modems/wiki/D-Link_DWM-222_stick/10 but This forum not cover DLink devices, you should check that at other sources.

In general, at differ ROS version the usb and lte can work together and other ROS divide them as LTE or PPP just by this switch… and I cannot answer you properly.
You should write to support@mikrotik.com or register at support portal: https://help.mikrotik.com/servicedesk and ask support about that.

Yes, it seems I need IgnoreDirectIP=No in order to run LTE1, so that USB device is not showing up as LTE2 automatically-I’ll have to write Mikrotik support…
