TRB501 reboot in 5G Mode since Firmware 7.22.1

Hi,

since the update to 7.22.1 and I activate the 5G Mode, the TRB501 reboots every 2min.

The only way to get out of this loop is to disconnect the antenna and reboot the device. After disable 5G, the TRB501 work as expected.

Greetings,

Apologies for the delayed response.

Could you let me know which firmware version the device was running when it was working properly?

Was the firmware upgrade the only change made, or were there any additional configuration changes?

Also, what firmware version is currently installed on the modem? You can check this by running the following command in the router’s CLI:
gsmctl -A "ATI"
Instructions on how to access the CLI can be found here: Command Line Interfaces - Teltonika Networks Wiki

Do you have anything configured under System → Maintenance → Auto Reboot?

Does the router reboot (becoming unreachable), or is it only the modem that restarts(mobile connection is lost)?

Best Regards,
Justinas
