I’m doing a project whit an Azdelivery D1 Mini with an ESP8266-12F WiFi chip.
When I tested it at my desk it worked fine, I powered it via the micro usb connector either via the usb port of my computer and via a 5V 1A power supply, then I took then the board and the power supply to their final location but I started having problems connecting to the WiFi.
I tried to keep the usb cable and the board away from the nearby AC cables and I tried changing the power supply but the problem remained.
Without moving the board I tried to power it with my laptop to try to do some debugging, it connected right away whit a much lower and stable ping (8ms stable powered by the laptop, 100+ ms and fluctuating a lot when powered by the power supply).
Then I powered it whit a power bank and the behavior was identical as when it was powered by the laptop.
What should I do? Should I try to buy a better power supply? Or should I try to solder a capacitor to try to smooth the voltage?
Thanks for the help
