Strange ESP32 C3 SuperMini

[json2024]

The ESP32 C3 SuperMini CAN NOT connect to WIFI normally when using a pin female header.

Once a pin female header is used, the ESP32 C3 SuperMini fails to connect to WIFI.

Even just connecting a pin header socket to pin 21 causes WIFI connection failure.

As long as pin 21 is not connected to the pin header socket, everything works fine.
If a pin header socket is not used and instead jumper wires are used, everything works normally.
Also, I have confirmed that there are no issues with the pin header socket, such as short circuits.
I have tested two ESP32 C3 SuperMini boards and both have experienced the issue.

What could be the reason for this?

Looking at the photo, I have doubts whether the ceramic WiFi antenna (red rectangular) is soldered properly.
I would resolder it manually to see if it helps.

Might be a bad module; it's known that some manufacturer of boards marked as C3-supermini messed up their routing leading to crap WiFi performance.
