I have two similar ESP8266-01, Chip is ESP8266EX.

1. I tested the cards with "HelloServer" example program, which comes to Arduino IDE with the other ESP8266 stuff.
- Other card works OK. The other does not make connection to my router. It only runs amok in this loop:
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print("*");
}

2. I Tested the cards with a simple AccesPoint program from
https://tttapa.github.io/ESP8266/Chap07 ... tions.html
- Both cards worked as they should.

I installed the programs many times and tested some similar programs. I also changed the prommer.
I even made a factory reset to one of my routers. The distance to the router was about three meters.
- The other card does not work with my routers whatever I do.

What should I test next with this card ?
It is not so important to make this cheap card work, but I'n interested.
