Question

Hi all. I've got a RUTX12 with SIMs in both primary and secondary slots, and it's set to load balance across them. Nothing is connected to the WAN port or USB, and the only clients are on wifi.

It works perfectly most of the time, but a few times a day all the lights on the router for the secondary modem will switch off. Signal lights, 2g, 3g, 4g lights and SIM2 light. All traffic is routed via the primary SIM when this happens.

Under Mobile > General, as soon as I click on General a notification pops up 'Error while loading data'. The two tabs say SIM1 and SIM, normally it says Primary and Secondary. On the SIM1 tab the only settings available are Operator Settings, Enable on/off and SMS Limit Settings on/off. The normal settings are available under SIM.

If I click on Interfaces, MOB2S1A1 is stopped. 

Rebooting the router fixes it, but only for a few hours. Anyone know what the problem could be?

Firmware version	RUTX_R_00.07.00
Firmware build date	2021-07-14 08:37:49
undefined firmware version	EG06ELAR03A05M4G
Kernel version	4.14.221

Comments

I'm seeing the exact same issue, but I'm on FW 00.07.01 and kernel 5.4.147, but when the second modem goes away sometimes the primary also falls over and takes a while to re-connect. Rebooting does not always solve the issue.

Both modems are on firmware EG06ELAR03A05M4G

I've also tried a factory reset and reconfigure but no change.

Hopefully someone can come up with a fix.

Hello,

I would like to recommend to upgrade your  modem 2 firmware:

1. Download this: https://kaunas.teltonika.lt:444/f/0b83d2356085413a9b94/?dl=1

2. Extract those files in that zip into folder called: EG06ELAR04A04M4G

3. Upload that folder into /tmp directory of your device using SCP / WinSCP app with SCP protocol

4. Go to CLI of your RUTX12

5. Input these two commands:

echo 1 > /sys/class/gpio/modem_reset/value

echo 1 > /sys/class/gpio/modem2_reset/value

6. After that enable modem2 with command:

echo 0 > /sys/class/gpio/modem2_reset/value

7. Type in /usr/sbin/quectelFlasher -f /tmp/EG06ELAR04A04M4G

8. Flashing should start, wait for it to finish.

9. When it's finished execute:

echo 0 > /sys/class/gpio/modem_reset/value

echo 0 > /sys/class/gpio/modem2_reset/value

Regards.

Thank you for the speedy reply! However, the transfer in WinSCP almost finishes but it seems to run out of space on the router -

scp: /tmp/EG06ELAR04A04M4G/update/NON-HLOS.ubi: No space left on device

Is there any way I can clear space? I don't have any packages installed on it.

One suggestion would be to factory reset your device (to clear all cache) and another is to mount USB storage https://wiki.teltonika-networks.com/view/RUTX12_USB_Tools#Mounted_File_Systems

Thanks, I'm doing off a USB stick but it looks like the quectelFlasher doesn't exist - I get the message below, and I can't see it in the directory either. Is it something I can download?

 /usr/sbin/quectelFlasher: not found

---

I am sincerely sorry. In the newer firmware releases, you should use quectel_newflash -f

---

Thanks again for the prompt reply, but I'm still getting the same message. In /sbin there's no files beginning with quectel at all?

---

It is in /usr/bin

Regards

Thanks flebourse, found it and the program runs. However, I get the following error - any idea why this was? I've entered in the commands as Vykintas posted, and done it after a fresh boot.

The only difference is that I'm flashing from a USB stick due to the lack of internal storage.

No sorry no idea. To free some storage space check your /tmp: df -m and du /tmp you should have about 100-120 Mb free after a reboot.

Hi, i receive same error  'Error while loading data', with same issue on mobile configuration tabs (Sim1 and Sim),  I'm trying to update modem firmware but executing command on point 5

echo 1 > /sys/class/gpio/modem_reset/value 

i receive this error -ash: can't create /sys/class/gpio/modem_reset/value: nonexistent directory    

inside gpio i haven't modem_reset and modem2_reset directory, i have only  following folders: export, gpio23, gpio24,gpiochip0,unexport.

Installing framework RUTX_R_00.02.05.2 i'm able to see primary and secondary sim configuration, but in there is a pop up saying Modem not connected (in system log there are a lot of Modem not found entry).

Any idea how i can proceed?
