Thank you Marco for your answer.
I got a reply from BMD: use it in the state with ncat
Not even a procedure for a return to factory settings!!!

It's a generation of out-of-warranty equipment, but some indication that BMD does not sell disposable equipment or that the company respects environmental values would have been appreciated.
I'm going to open it and check the points you mentioned but I wanted to rule out a software flaw first.
Have a nice day.
