Possible Solution

Steps to Reproduce the Problem

1. In Network > Interfaces > General Settings for the 5G Modem > Authentication Type > Set to NONE
2. and save and apply > Authentication Type Should be set to NONE
3. Go back to the setting page, and you will see It reverts back to PAP/CHAP

Context (Environment)

I'm using GOMO.PH SIM Card.

Already tested on Mobile Phone, no problem.

Problem is when using it with the router.

I'm not sure whether it's the router or SIM is the problem. Please help.

There is a bug, default is "none". You can check via "uci get network.4glte.auth" via SSH on the router if it's correct or not.

Do you know where "/sys/devices/platform/soc/11200000" is coming from ? If not it should also be in "uci show network" via SSH on the router.

@Ysurac , thanks! the output is below:

root@OpenMPTCProuter:~# uci get network.4glte.auth
uci: Entry not found

Do you know where "/sys/devices/platform/soc/11200000" is coming from ? If not it should also be in "uci show network" via SSH on the router.

uci show network output:

network.4glte.device='/sys/devices/platform/soc/11200000.usb/usb2/2-1/2-1.1'

I was just writing to ask that.
It's configured in ncm, I only tested Quectel modems in mbim mode. Can you switch it to mbim (easier to use with ModemManager) ? mmcli -m 0 --command='AT+QCFG="usbnet",2'

Can you give me the result of uci show network.4glte ?

Can I please ask what do you mean by "easier to use with ModemManager"?

I may be doing it wrong, but the setup is like this:

1. In Network > Interfaces > 4glte > Edit :
   Protocol: MBIM Cellular
   Modem device: /sys/devices/platform/soc/11200000.usb/usb2/2-1/2-1.1

2. In System > OpenMPTCP Router > Settings Wizard > Interface Settings > 4glte
   Type: Normal
   Protocol: Other
   Multipath TCP: Enabled

[chubx]

With MBIM Cellular Mode, the output for your requested commands are:

root@OpenMPTCProuter:~# mmcli -m 0 --command='AT+QCFG="usbnet",2'
response: ''

root@OpenMPTCProuter:~# uci show network.4glte

network.4glte=interface

network.4glte.pdptype='ipv4v6'
network.4glte.multipath='on'
network.4glte.addlatency='0'
network.4glte.metric='24'
network.4glte.ip4table='24'
network.4glte.ip6table='624'
network.4glte.defaultroute='0'
network.4glte.delegate='0'
network.4glte.apn='gomo.ph'
network.4glte.auth='none'
network.4glte.ipv6='0'

[chubx]

Bug? I think another bug in MBIM configuration page.

When I edit in Network > Interface > 4glte > Modem Device: /sys/devices/platform/soc/11200000.usb/usb2/2-1/2-1.1

After saving, the Error comes up: Error: Network device is not present

And when I use command uci show network.4glte, output is:

network.4glte=interface
network.4glte.proto='mbim'
network.4glte.label='4glte'
network.4glte.pdptype='ipv4'
network.4glte.apn='gomo.ph'

Remove DNS set on the interface, set it as ModemManager proto not as mbim and reboot

[chubx]

Remove DNS set on the interface, set it as ModemManager proto not as mbim and reboot

Is this where i set the protocol to ModemManager?

If so, I already did. And still the authentication goes back to PAP/CHAP, after setting to NONE.

Plus, the error (updated, see below):
Error: Unable to set preferred mode.

Update:
I set to:
Allowed network technology:
Any

Saved/Applied, and rebooted, now I get:

[Ysurac]

Can I have again the result of mmcli ?

Seems far better. For the preferred mode, only one mode is supported that is the current one, quite strange.
I have this on a RM520N-GL:

@Ysurac I've tried single mode 4G only, but that did not work, and other combinations.

The only thing that made it worked is setting it to any

On another Note:
When going to the OpenMPTCP page, it takes quite a while to load up. It's abnormally slow.

"any" is the only available mode on your modem.
OpenMPTCProuter status page ? It's when some tests timeout. All is green or not ?
