otacon24:

which were successful but i have no modemmanger option under the wwan interface

Are you sure that it is not available in “Protocol” drop down list ?

otacon24 · 2022-08-24T22:19:30.314Z

Not from what I can tell

That is because no device is assigned to this interface. I am not sure how to proceed, you should probably check the log, may be it contains a clue

Do you have any updates on better support of higher cat modems in question?

Thanks

We are working on a list of USB modems.

Pls allow a few weeks and we will upgrade the firmware with modem support.

i7bar · 2022-12-11T22:46:29.430Z

Latest firmware 4.1.0 release 7, clean install, EM160R-GL is attached in the external USB3 enclosure.
Looking at the log in luci the modem has been detected:

BUT neither the gl-inet GUI detects it nor a new interface has been created.
So, I guess it is still unsupported (without manual changes), please confirm.

Thanks.

I am using the exact modem and it works well.
Do you use a USB 3.0 hub?

i7bar · 2022-12-12T20:24:35.822Z

Oh, this is very interesting. I am using a self powered USB 3 enclosure which works just fine with other routers.
Could you please do the following:
a) what is the version of AXT1800 firmware?

b) Can you press “Manual Setup” and show me a screenshot of the parameters defining protocol / port?

c) I assume you run the modem in QMI mode? Could you go to

http://YOU_MODEM_IP/#/modemmanage

run the following manual command: AT+QCFG="usbnet"

and show the screenshot with the command output?

d) can you please open luci and show the screenshot of the “Interface” page (want to see the name of WWAN interface, I have to create it manually).

e) can you please open the corresponding WWAN (LTE modem interface, whatever name it can have) and show me a screenshot with the general settings of the LTE interface (want to see protocol / device name)?

–
Last but not least - are you sure that you run your modem on the stock firmware and did not install any additional packages (I see that you work for GL.iNet and therefore your router could be used for tests, .i.e. some additional packages could be installed in the past)?

Thanks!

alzhao · 2022-12-13T11:13:51.418Z

Maybe it is the firmware version.

I am using a firmware that compiled internally. I forgot this info. Let me check with developers about firmware and modem support.

But here are some secreenshot for you.

alzhao · 2022-12-14T02:08:18.322Z

Checked again. 4.1.0 release 7 support this modem.

Also from your log, the modem is supported.

Can you check if you have all the ttyUSB device in /dev/?

Also did you change anything on the modem?

I wrote in my initial post: “the modem was detected (info in the log), but neither the gl-inet GUI detects it nor a new interface has been created.”

I can make it work if I manually create the proper interface and assign to it the correct device (it will be /dev/cdc-wdm0 in case of QMI or /dev/ttyUSB2 or /dev/USB3 in case of UTMS) but this not what users have to do.

Can you please provide the rest of information I requested (d, e) ?

Thanks.

lizh · 2022-12-14T03:33:21.069Z

Can you provide the ID of the device? It can be viewed through ‘lsusb’.

The connection is set, I can control the modem via luci but gl GUI does not show the modem info, it says " NO MODEM DEVICE FOUND".

This is the 4th time when I am trying to get the answer to a very simple question - WHAT IS THE NAME OF WWAN INTERFACE THAT HAS TO BE CREATED BY GL AFTER THE MODEM HAS BEEN DETECTED BY GL SOFT?

Thanks

alzhao · 2022-12-14T06:46:57.907Z

As long as you have ttyUSBx and cdc-wdm0 the modem should be displayed.

lizh · 2022-12-14T07:47:11.153Z

You can bind to the cloud platform to share with me, I will check the specific situation remotely.

My account is ‘zhangli’.

i7bar · 2022-12-15T01:43:52.819Z

I re-uploaded the latest firmware, reset the settings. I bound the device to a new account opened on goodcloud and shared it with your account. Right now the router works in repeater mode, the modem is attached and detected (the records in the log) but cannot be seen in GL GUI.

gl21682×1332 236 KB

But if you jump straight to

http://192.168.8.1/#/modemmanage

you will see that the modem is alive and connected:

The name of APN to use: h2g2, no authentication.

lizh · 2022-12-15T09:03:45.695Z

Hi i7bar:

Thank you very much for your feedback.

Maybe this modem or sim card is special,So some information about the sim card cannot be obtained. As a result, the web page is not displayed.
We will accommodate this special case.

lizh · 2022-12-15T10:36:19.197Z

I temporarily updated a few packages. It should now display normally.

However, since mcc/mnc cannot be obtained, you need to fill in the APN by yourself.

Hello,
Thanks for the troubleshooting. Yes, now GL.Inet GUI properly detects the modem, so at least this problem has been fixed.

Please two more things to consider:
a) it would be extremely useful if the edit field “AT Command” could preserve the list of the previously entered AT commands(at least during the current session);
b) it would be even better if the user could add this own modem specific AT commands to the dropdown list stored in “Shortcut” field since the same commands will be entered again and again;

The reason why entering AT modem specific commands is important is pretty simple - nowadays just connecting the modem to a cell tower is NOT ENOUGH. In case of EM160R and other modern modems users will want to choose the band / group of bands (by specifying what bands to connect), enable certain types of aggregations (by specifying what bands to include in aggregation), lock the modem to a certain cell and so on. All these steps are essential in getting a robust and fast cellular connection, contrarily to autoamtic connect the the most utilized band in the area and therefore being providing the lowest speed and highest latency.

I am resetting the router and will wait for the next firmware that it supposed to provide all users of EM160R-GL LTE modem with the aforementioned fix.

PS: I asked the question, did not get any answer and therefore will answer myself - the name of WWAN interface which is used by GL-Inet GUI and mwan3 is ‘modem-2-1’ where 2-1 is the

‘2-1’ is the USB-bus.

As for other suggestions, will consider them.

Thanks!
