B11 turns on, but does not give wireless link, SFP and RJ45

Hello good. I have a B11 that lights up (red LED on power) but does not give a wireless, sfp and rj45 link. Nor does the 2.4Ghz network appear when it is energized. Did it happen to anyone? Do you know what it could be? Thank you.

Sounds like a bad radio.
