Note

This board has been reporting having hardware issues, please check the forum for more information.

A workaround is to add or enable in configuration.h:

#define ESP32_WIFI_TX_POWER WIFI_POWER_15dBm

You may also need to lower the value if not working, the possible values are WIFI_POWER_5dBm, WIFI_POWER_8_5dBm, WIFI_POWER_15dBm
