user76804: I bought an ESP8266-01 module. I attempted to upload following code onto it.
void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
Serial.println("I'm working");
Serial.println(millis());
}

Then I powered it and there was nothing in Serial monitor. Also my computer lost wifi connection. What's the cause of this error? How to solve it?

user76804: Solved:
I catched more details. ESP creates Wi-Fi network. It causes jamming.
