Hi

As I write this title, Is it important to upgrade routerboard firmware??

I don't know why upgrade firmware.

Please tell me answer

Thanks,

You must read the firmware changelog for fixes. This will determine if it is important or not for you. Depends on use and config of your devices. It is recommended install latest version. This can make you save time by solving problems in some configs or scenarios.

you can see what kind of changes the RoutrBOOT updates usually include:

if some version is not listed, it means we added support for a new model of the same CPU family, but did not want to reveal it yet

Thanks all
