Loosing credentials of RUTX50 after setting LAN connectivity to static

NETWORKING SOLUTIONS
1

Hi together
I have set LAN connectivity to be static and disabled DHCP4 and DHCP6.
After pressing submit button web GUI has shown redirection. Redirection did not work but it is not important. Static IP address on LAN1 port become visible and RUTX50 started to become reachable. My device started to send curl command and modem replied with error:

Error

Unauthorized

It is not first time that I have encountered problem when LAN is configured as static. Last time I pressed RESET button for couple seconds and after that I needed to use default username and password sealed on modem to reconfigure RUTX50.

Yesterday I did 2 steps more since last time was set static option (disabled DHCP4 and DHCP6) and now I can not login to modem. It rejects on web gui credentials and it rejects credentials on ssh connection.
It can be observed that DHCP4 works after factory reset but it is not possible to login.

Firmware is 7.12

Hello,

Just to clarify, after disabling the DHCP server on the LAN, did you assign a static IP and correct default gateway on your end device? Without this step, it would not be possible to reach the RUTX50 locally.

Additionally, it is always recommended to ensure your device is running the latest firmware. At the moment, the RUTX50 can be updated to RutOS version 7.13.3.

When the described issue reoccurs, have you tried clearing your browser cache and reloading the login page?

Let me know if the issue persists after verifying these points.

Kind regards,

Modem was properly configured. RUTX is reachable locally bit it reports with authentication error on GUI and via CURL. From 2 different PCs connection was tried but it does not work.

Is it possible to connect to the device through SSH, execute the following command, and reboot afterwards?

rm /usr/share/vuci/menu.d/menu.json

Let me know the outcome.

ssh authentication does not work. After pressing RESET button via screwdriver for a couple seconds it starts DHCP server in modem but there is no way to connect with them. Web GUI login page appears , ssh works but authentication fails in both cases.

You may not be holding down the reset button for long enough. The RUTX has a 3 stage reset and you release the button, at the correct point.

Action = Reboot, Min Time = 0, Max Time = 5 sec

Action = User’s default configuration (if one has been saved), Min Time = 6, Max Time = 11 sec

Action = Factory defaults, Min Time = 12, Max Time = 20 sec

All is revealed in the RUTX50 manual, should you feel the need to read it.

Hello,

To assist you further, I would appreciate some additional details about the current situation:

  1. Could you confirm whether your PC is obtaining an IP address from the default DHCP pool of the RUTX50?
  2. Do you see any assigned IP on your end device (PC)? Checked with ipconfig (windows) or ifconfig (linux) commands?
  3. Are you able to ping the default LAN IP address of the RUTX50 (192.168.1.1) from the PC?
  4. Did performing a reboot after the factory reset result in any change?

If the initial issue still persists, it might be useful to consider accessing the bootloader menu and attempting to flash the firmware directly through it. Instructions for this process can be found here.

Please let us know how it goes or if you need any assistance during the process.

Kind regards,

1)Yes it is obtaining IP address
2) My PC 192.168.1.241
3)Ping successful
4) No difference only in web GUI writes “Invalid username and/or password. Please try again”

Are you using the default password, found on the device back label, when accessing device WebUI or through SSH?
