Anyone got any ideas that I could try?

Tried something else. Added line in red below to ifnet.conf which I found in the logs after I renewed the IP address using the OPNsense GUI ...

notify 101 {
   match "system"      "IFNET";
   match "subsystem"   "!usbus[0-9]+";
   match "type"      "ATTACH";
   action "ifconfig $subsystem up";
   action "/usr/local/etc/rc.newwanip ue0";
};

Disconnected/reconnected the modem, WAN interface came up but it didn't acquire an IP. Would I need to introduce a delay or something after bringing up the WAN interface and if so how would I do that?

I'm still having a bit of trouble trying to figure this out.

I'm guessing that I need to add another "action" in the ifnet.conf that will renew the IP address just after the WAN interface comes up. I've opened up a shell in OPNsense to try out a couple of commands to renew the IP address that the USB modem assigns but I'm not even sure of the command to renew.

I've read that ...

dhclient -r

... should renew it but when I run that it says there is no "r" option.

So how do you renew an ip address in OPNsense/FreeBSD? If I can work that out then adding that command line to the ifnet.conf might resolve my issue.

Grateful for any information anyone can provide.

Cheers

Apologies for the delay getting back to you. OPNsense and the USB modem have been working quite well up until about a week ago and then I noticed that the USB modem is detaching and reattaching 6 seconds later once a day at random times (but usually in the early hours of the morning) so resolving this has jumped the priority list :)

I've added the line as suggested to my /usr/local/etc/devd/ifnet.conf as per below ...

notify 101 {
   match "system"      "IFNET";
   match "subsystem"   "!usbus[0-9]+";
   match "type"      "ATTACH";
   action "ifconfig $subsystem up";
};

... and I've had some success.

When I detach the USB modem and attach it again I've noticed that the status of the WAN interface is UP (previously DOWN after detach/attach) but it doesn't have a DHCP address from the modem. So I went to "Interfaces | Overview" and selected the dropdown for my WAN interface and then hit the button to renew the DHCP and the WAN interface started working again.

So I'm nearly there. I guess I need to add another line perhaps to renew the DHCP after the WAN interface comes up? I just have no idea what I need to add though.

Can you provide another gentle push in the right direction?

Many thanks

Craig

Do you have the system logs (generic) for this?

Sorry for the delay. Had an internet free week! General log file below ...

These are the logs for when I detach the modem USB cable and then reattach. As you can see the USB modem is detected but the WAN interface doesn't come up and doesn't get the IP address from the USB modem. If I reboot OPNsense now the USB modem will be detected and the WAN interface will come up and be assigned an IP address from the modem.

I'm not sure what I would need to do with devd configuration for a specific event.

Thanks

I was under the impression that when using a quirk, if I disconnect/reconnect the modem it would be recognised and the WAN interface would be assigned to it but that's not happening for me. The modem is recognised when I plug it back in and the CDC Ethernet Control Model ECM assigns it an Ethernet MAC address but the WAN doesn't get assigned to it. Small thing I can live with but if there's a way to sort it out I'm all ears.

Anyone got any ideas of what I could try?

Please also don't forget to go to the interface settings in the GUI that uses the modem and set it to "Prevent interface removal" to avoid config reverts when the USB should fail to come up for some reason.

Thanks Franco - I've made that setting - it's sticking nicely.

Do you have any idea as to how I can get the network to come up when I disconnect/reconnect the network as per ...

Right probably getting a bit out of my league now.

You could try the route of creating a script with those two lines below and place the script into the rc.syshook.d directory as per Franco's reference below ...

https://docs.opnsense.org/development/backend/autorun.html

That worked for me in one of my attempts of getting something working.

Hopefully that will steer you in the right direction. I'm afraid I'm as new as you are are doing this stuff.

Cheers

Craig

You do it from the OPNsense webpage. Need version 18.1.5 or later as specified by Franco.

Goto ...

System | Settings | Tunables

.... and add a new tunable. Worked for me! Let me know how you go.

Cheers

Craig

OK I've done a bit more testing. I'm posting this for anyone else who might be trying to get an LTE modem working.

First of all I upgraded to 18.1.6.

Secondly I added a tunable with the name ...

hw.usb.quirk.0

... and a value of ...

0x0846 0x68e1 0 0xffff UQ_CFG_INDEX_1

... (but to be honest I'm not sure why I use INDEX_1).

Thirdly I added the os-boot-delay plugin as recommended by Franco.

I removed loader.conf.local that I had created early and also deleted a file I had created in rc.syshook.d that ran the script ...

usbconfig -d ugen0.6 set_config 1

I then rebooted and my modem has been recognised and assigned to the WAN interface. I'm very happy with that.

Thanks for that additional information.

I was only on version 18.1 (based on the image I downloaded) so upgraded to latest version (18.1.6). As soon as it rebooted my USB modem was detected and assigned to the WAN interface. How good is that!

I had previously put an entry into the rc.syshook after my initial post but it didn't work. Looks like it's working now. I notice in the rc.syshook directory that there are other entries all beginning with a number. Does the number have an effect on the order of applying the scripts in there?

I'll have a play around with what I've got working today. I might have an additional question.

Many thanks for your help.

Hi

I'm new to OPNsense but used pfSense for quite some time. I've just installed 18.1 on a spare laptop and my WAN device is a Netgear AC800S 4G/LTE modem. To get the device recognised by OPNsense I've run the console shell and typed in ...

usbconfig -d ugen0.6 set_config 1

The modem is then recognised as an ethernet device with a MAC address.

I then run option 1 "Assign interfaces" from the console and select local ethernet connection for LAN (em0) and Netgear modem for WAN (ue0). Once done I've got internet access and I'm very happy.

The problem is that when the device is rebooted it forgets about the modem. I've created a new file ...

/boot/loader.conf.local

... and added the following line ...

hw.usb.quirk.0="0x0846 0x68e1 0 0xffff UQ_CFG_INDEX_1"

... as per a forum posting I found here (which worked for pfSense) ...

https://forum.pfsense.org/index.php?topic=93393.0

However, when I reboot the modem is not configured on the WAN interface. If I run through the procedure above again I can get it operational.

Does anyone know how I would make the ...

usbconfig -d ugen0.6 set_config 1

... to stick so that the modem is recognised on boot and OPNsense sets up the WAN interface correctly?

Many thanks

Craig
