I don’t know why I couldn’t find the wiki article in the first time. However I tried that and I had to find out that I don’t have any ttyUSB* devices at all in /dev.
Only ttyACM0, ttyACM1 and ttyACM2. The webui modem info says ERROR:
OK but shouldn’t I see the device in /dev?
I can’t find any ttyUSB*.
It is working with Windows 10 and the SIM also works fine (just tested it with the installation on it).
I find some firmware issues with that card but can’t find an easy firmware update installation for it but I’m also not sure if that’s the reason why it doesn’t show up in dev.
Edit: my set AT commands are just for the PIN (first) and APN (third). The syntax is as described in the wiki article.
OK firmware is 1.2 (Sierra Firmware update service in Windows), but webui says 1.1.11???

Also the machine says at its startup: “interface red0 doesn’t exist” but it’s listed as defined device for red in the tui setup.
Edit: The wiki says:
" Authentication Authentication is necessary for some APNs and the username and password can just be entered into their respective fields."
The used ISPs APN does not need any authentication but I must enter a user name, otherwise the webui strikes. Hopefully that’s not why it’s not working.
So I tried the same with my Panasonic Toughbook that has got an installed Sierra EM7305, which is working fine in Windows 10 and recognized by ipfire. However I don’t even get any ttyUSB or ttyACM devices listed at all this time and therefor can’t even see any Modem information. I also updated the firmware from the manufacturer without any change in ipfire.
I will try it later, because the SIM slot of the T440s is quite bad and I can get harshly the nano SIM with an adapter to full size into the slot without breaking it.
I just found out (yesterday) that using the Toughbook will be an better idea (battery power 15h) and a little bit more ram + ssd and the same WWAN modem family but I can’t even find the device at all but can be selected in the setup. Any ideas what that is supposed to mean again?
So I got an Sierra EM7455 for testing purpose and there is nothing new. Works fine with Windows 10 and Ubuntu 19.10, but not with ipfire. There is still no ttyUSB or ttyACM device listet but I can still select the device for the red interface. At the startup ipfire still complains that interface red does not exists, just as with the EM7305 and EM7345. So ipfire is just not capable to run sierra wwan cards at all.
I just tried pfsense and it also doesn’t work. When I was searching for explanations I came up to the point, that newer wwan modems just support QMI and MBIM protocol and no ppp anymore. I also didn’t know that ppp is limited to 25Mbit/s which is ways to slow for my application.
Since there is no QMI or MBIM implementation in ipfire nor pfsense there is no way to get it working.
May I enable it when I will build ipfire the next time?
As far as I have found out (read a lot of articles) the Sierra Modem after gen 73xx doen’t support it any more and use MBIM. I can confirm that this driver is loaded for my EM7455 with ubuntu, kali and also ipfire. It’s different to my EM7345 of my Lenovo T440s.
I know. But I’m pretty sure all you guys live in or near Mannheim so I can give you my laptop .
I thought it’s an good and more cost efficient idea to build a mobile firewall appliance for my personal needs with lte wwan and want to terminate the contract of my fixed line because sometimes I’m working on construction sites for weeks till month. It makes no sense to pay for services at home if you’re not at home. The Panasonic thoughbook is not restricted to branded hardware components so I can run any wwan and wifi card I want to. That’s perfect for my needs.
