Hi!
I have a few Teltonika RUTM51s that I use sporadically (the odds are that some of them are only used once or twice a year).
When I plug one of these routers back in, I stare at the Mobile network type LEDs, hoping that the 4G and 5G LEDs will light up (Device is connected using 5G NSA) .
But sometimes, I get this:
All LEDs turn on and off in sequence one after the other, indicating that “The device is attempting to connect to a mobile network operator,” even though the router is actually connected: the admin interface shows it, and I can browse the internet freely after connecting to the router’s Wi-Fi or LAN.
What is happening?
How can I resolve this issue?
They are currently running firmware version 7.23 or 7.22.x.
