for 4.4.5 i modified here, then initially the router couldnt detect the modem even after one reboot
i switched to another usb modem that uses tethering then switch back to the external modem it then able to establish data connection (and set ttl works)
how long it can stay online, will monitor
update modem not so stable in this firmware, it goes offline randomly and becomes undetected by mt3000, maybe theres more configuration required but its out of my capability
Thanks for the reply and taking a stab at it. This is difficult not having my cell modem anymore. Is disappointing they removed signal strength info and set the default USB port to USB0 with this firmware so making AT commands is a pain. Have to select USB3 every time you issue a command and can’t easily set your antenna due to no cell signal strength info.
GL-iNET. Can you help us out with this? The previous firmware we were able to get things working after editing the qmi.sh file but now that file has very different content and we can’t use our modems anymore.
I have Beryl AX (MT-3000) + GL M2 with T77W968 / DW5821e in it. When I plug the board to the router nothing shows up in Cellular nor Tethering.
Tried on firmware 4.2.3 and 4.4.6 - same result.
—Update
I can see it’s usb-modeswitch related - move the discussion here
I think that with stock firmware it is not possible. I flashed pure OpenWRT v23 but still no luck. The modem is visible in mmcli but SIM card will not register.
I followed this tutorial. Apparently prepering the modem is also necessary see this but I don’t want to do it.
It’s already my second modem that I can not connect. I sold L-860 because it didn’t work with stock firmware. I though I will have more luck with DW5821e but it doesn’t look like this.
A couple days ago I bought another L-860 (in shipping) and going to sell DW5821e. Hope it will connect via OpenWRT v23.
You need to remove scripts from /etc/hotplug.d/usb and then cdc-wdm0 device will show up so you can add an interface for MBIM or QMI (if your modem is in QMI) connection without using Modem Manager
