Hello Community,

I´m new and not really familar with my new router RUTX11.

It is brand new router and I started the new router. Everything works fine. Then I proceeded a fimware update. After that the problems started. First I got not access to RUTOS at But this is fixed now. After that I had problems that the router and got no acces to 4G LTE mobile net. After several new reboot´s und reset´s, the system works, but RUTOS gives not correct informations about modem status. Modem said SIM card is not inserted altough it is inserted and works well. When I started a reboot of the modem, he said modem not found.

Can someone help me?

Thanks in advance. Mathias

Hello Mathias,

Thank you for your query.

Could you please try to reinstall the device firmware via the bootloader menu?

Here are detailed step-by-step instructions on how to do it:

  • First of all, please set a static IP address on your network interface (e.g.
  • Use private/incognito Web browsers window with cleared/disabled cache
  • Power on the device while holding the reset button. Flashing all 4 Ethernet LEDs indicates that the bootloader’s webserver has started.
  • Access router via web browser
  • Upload new router's firmware. It can be downloaded from here: https://wiki.teltonika-networks.com/view/RUTX11_Firmware_Downloads
  • Wait a few minutes. The router's LEDs should stop flashing. Only LED with LAN cable connected to that port should be active.
  • Access router via web browser

Detailed instructions can be found here: https://wiki.teltonika-networks.com/view/RUTXxx_Firmware_via_The_Bootloader_Menu

Note: if the modem would not recover after this, this could signal a more serious issue, potentially a hardware issue and you should contact your supplier to return the device as potentially faulty one.

Hello Dziugas,

thanks a lot for your quick answer. It was really helpful for me.

But, unfortunately, the modem didn´t start again. I will contact my supplier to get a new router.
