Need help to configure 4G with WE826 router

Yes,

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

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



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"
