Need help to configure 4G with WE826 router

Installing and Using OpenWrt

Yes,

P:  Vendor=1508 ProdID=1001 Rev= 3.18
S:  Manufacturer=Fibocom NL668 Modem
22

With this model you're limited to ECM.
BTW, do you have the APN configured on the modem? Setting the APN was not part of my modification to the ncm.json file.
Pls check with AT+CGDCONT?

I have the APN configured in /etc/config/network. I assume that is not "on the modem".

config interface 'wwan0'
        option proto 'ncm'
        option device '/dev/ttyUSB2'
        option mode 'auto'
        option pdptype 'IP'
        option apn '3iot2.com'
        option username 'multinet'
        option password 'multinet'
        option ipv6 'auto'
        option delay '30'

Querying it doesn't return any APN:

AT+CGDCONT?
+CGDCONT: 1,"IPV4V6","","10.58.162.174,0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

OK

Never mind, that was the wrong command. Yes, it's there:

AT+CGCONTRDP
+CGCONTRDP: 1,5,3iot2.com,"10.58.162.174",,"80.233.123.1","80.233.123.1"

OK
25

If username/password authentication is truly necessary, you will probably have to use a different connection procedure.

You better set the APN: AT+CGDCONT=1,"IP","3iot2.com"

Could someone please post the /etc/gcom/ncm.json config please.
I'm trying to get the Fibocom NL668 working on OpenWRT.

Thanks.

Normally I am quite diligent about saving files in a vendor-specfic folders for each project, but in this case I cannot find this file. So I guess I just pasted it in to an SSH session, or something. Sorry.

I managed to get Fibocom NL668 working in Openwrt 23.x as below using QMI protocol.
