RUT956 Event juggler and Wifi scanner missing

Networking Solutions Issue
1

Hi all

I have just updated my RUT956 to **RUT9M_R_00.07.22.1.
**
After that, I have seen that Event Juggler is missing, showing several errors.
Several errors appear in system log too.

Now, I have learnt that the package Wifi Scanner is not working either.
No errors in the Wifi Scanner window, but there are errors in the System log:

Greetings,

Could you please try reflashing the router’s firmware via the bootloader menu by following these instructions: RUT956 Device Recovery Options - Teltonika Networks Wiki

The issue may have occurred due to software migration problems during the firmware update, especially if there was a significant gap between versions.

Best Regards,
Justinas

Thank you for your answer, Justinas.

The previous firmware was rather recent, 00.07.20.3

Anyway I will have to wait until I can go where the router is.
I will inform you then.

Can I do anything meanwhile?
I made a backup before the update. Can it solve the issue?
I do not want to try it if it could make things worse, as the other router functions are working well.

Best Regards
Luis
