I have installed WLED on a NodeMCU ESP8266 v3 board to control a 3-meter WS2812B LED strip. I am using a power supply AC 110/220V - DC 5V 20A 100W. I experience frequent Wi-Fi disconnections, and sometimes the LED strip remains on even without a Wi-Fi connection, or the LEDs flash and then stay on without any logic. I tried reinstalling WLED, but I didn’t get any results. When I disconnect the power supply and the LED strip and power the board with a USB cable, I get a stable Wi-Fi connection. I’m going crazy. I even bought a new ESP8266 board, thinking it was damaged, but I have the same issue. Who can help me? Thank you very much. ---

After powering up just the strip, does the strip light up? ---

Perhaps you’ll need level shifter and possibly a proper controller board. ---
