ESP32-S2 server cannot connect to the router

[scarecrowthere]

I have a ESP32-S2-SAOLA-1 board. When I run WiFiScan example in Arduino environment with ESP32S2 module, the program is running properly and I can see the routers nearby. But when I run SimpleWiFiSever example with ssid and password modified, the program is waiting for connection for ever. Did I miss anything?

I have read that some modules have very poor range due to the antenna being attenuated by poor design.

I bought the board from Digikey and it should be an Espressif official product. If it's about the hardware problem, is it possible to return it?
