Using ATX1800 with QUECTEL EM160R-GL

alzhao · 2022-12-12T04:50:19.872Z

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!

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.

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.

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.

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.

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

qmi_wwan 2-1:1.4: cdc-wdm0: USB WDM device
Thu Dec 15 20:20:49 2022 kern.info kernel: [ 14.178317] qmi_wwan 2-1:1.4: QuectelEC25&EC21&EG91&EG95&EG06&EP06&EM06&BG96&AG35 work on RawIP mode

Thanks.

lizh · 2022-12-18T02:20:23.338Z

‘2-1’ is the USB-bus.

As for other suggestions, will consider them.

Thanks!

TazzyTazzy · 2022-12-30T05:59:54.771Z

What packages did you update? I’m trying to get the EM160R-Gl working a Beryl. Thanks.

TazzyTazzy · 2023-01-02T10:18:57.830Z

I now have a Slate Plus connected to an EM160R-GL using firmware 4.2.0 Beta 2, and there’s still nothing showing up in the GUI. Firmware 4.1.2 also didn’t work.

Here’s a snippet from the kernel log:

[  175.041436] usb 2-1: new SuperSpeed Gen 1 USB device number 2 using xhci-hcd

Here’s my modem details from ATI command:

ATI
Quectel
EM160R-GL
Revision: EM160RGLAUR02A09M4G

And the usbnet query:

AT+QCFG="usbnet"
+QCFG: "usbnet",0

OK

Things I’ve tried:

Plugged in the USB and rebooted the router.
Rebooted the router without USB plugged in, and then plugged in after 5 minutes.
Changes the glconfig setting per this post. I’ve tried both ‘2-1’ and ‘1-1’ (rebooting each time).

I wish you would share what packages you updated for i7bar.

i7bar · 2023-01-03T02:01:19.863Z

I wonder what you see if you jump to:
http://IP_OF_YOUR_ROUTER/#/modemmanage

Can you show the screenshot?

PS: One more thing - can you show the list of available interfaces?

lizh · 2023-01-03T08:38:33.828Z

You can download the above firmware to use.

TazzyTazzy · 2023-01-12T00:45:37.698Z

Thanks for the reply. I managed to get it working perfectly out of the box using Rooter by modems and men with my old beryl. I’ve already returned the Slate back to amazon because I just couldn’t get it to work for the life of me, despite installing various packages.

robo89 · 2024-06-30T04:06:47.332Z

I know this post has been awhile. But I am wanting to build a router following your steps, but possibly with the MT3000 (Beryl AX) and the EM160R-GL modem. I found the EM160R-GL modem for sale but in the description, it states that "Note: it only work with PCIE mode, not work at USB potocol. Not work for USB Adapter".

Are there different modem versions to buy? How did you get your "EM160R-GL in a USB3 enclosure"? Maybe I am misunderstanding something. Thank you.
