Breakboard ESP01 no working

I use this breakboard for the ESP01 but what I don't understand is why just turning on the WiFi is not strong but when I use the ESP01 USB Programmer the WiFi can run normally?

Check that the pins are actually connected to the equivalent socket locations. I had one with a flaw where the ground connection was missing. After a few obscenities and a jumper soldered on the back side it worked fine. (obscenities optional)

Does that mean I have to solder directly to the pins in the socket to plug in the ESP?

No, on the back of the board there will be solder bumps where the pins and socket were soldered to the board. Just solder a wire between the unconnected pin and the corresponding socket connection bumps.

okay thanks. It's already working
Have you ever used tx rx to be the low high pin, why is it that when the rx is set high nothing can work?

// l298n
int tx = 1;
int rx = 3;
void setup(){
  pinMode(tx, OUTPUT);
  pinMode(rx, OUTPUT);
}
void loop(){
    digitalWrite(tx, LOW);
    digitalWrite(rx, HIGH);
}

Which particular 'Board' are you selecting (in 'Tools')?
