If you have an ESP32C3 board with poor wifi performance, check if it's a boad with poor design that has the ceramic antenna is too close to the oscillator: https://roryhay.es/blog/esp32-c3-super-mini-flaw

YMMV but adding a loop of wire in parallel with the oscillator improved wifi performance on mine.

(I first tried moving the ceramic antenna a millimeter outward, but that made no difference.)
