I cannot send any SMS via the router. I get a "Time Out" message after a few seconds. Receiving SMS works well.

I use the actual firmware (RUT2XX_R_00.01.14.4). The device is connected via LTE only, the data connection is established.

Resetting to facory defaults did not solve the issue. If I insert the SIM card into a normal mobile phone I can send SMS.

Hello,

Please tell me with modem firmware version you are using on your RUT240. You can check it by navigating WebUI > Status > Device. There you will see the modem section.

Regards.

Hello,

Could you reinstall your modem module firmware?

There are the steps:

Download module firmware https://kaunas.teltonika.lt:444/f/cdd5bae7da134d969404/

Connect your router to your PC folder where firmware is located via SSHFS

mkdir /mnt/new`

`shfs user@host:/tmp/slm_on_pc /mnt/new `
And enter command:
meig_firehose -f /mnt/new/

Hi Vykintas!

I have problems followning these steps. Maybe it's becuase my PC runs on Windows 10.

Can I put the needed file onto the router and update the firmware from there? I have access to the router via Putty and can copy files there. But mounting a folder from my windows machine does not work for me.

When I extract the downloaded ZIP I find several files.

shfs is not available on this version of BusyBox (V1.30.1).

Any idea?

You will need to download the SSHFS package from openWRT
