ESP8266 Community Forum

Hi all.

It's a little strange to ask this but how it can be possible?

So I'm using an ESP 826 module 1-F version (something like that) along with FTD 232 converter to upload the code from Arduino IDE.

Sometimes it works, sometimes I get errors.
And right now there is a problem:

If I'm just connecting the ESP to 3.3 V, my WIFI AP will lose signal and go off, same on the phone.

So if I'm connecting the ESP to 3.3 V, it says on my laptop "Disconnected" and aswell on my iphone.

I have like 8 neighbours, and after I connect tension to the VCC, half of WIFI SSID dissapear from the list.

This problem occurs randomly, and it doesn't care if is on the "FLASH MODE" or "Normal Mode".

What can be the problem? THank you.

I don't like these sentences.

The solution is simple: don't connect 3.3V to the ESP.

All joking aside: an ESP should never (either in AP- or client-mode) take down any WiFi network, unless the radio is generating a lot of noise, resulting in your ESP becoming a jamming device (which BTW is illegal).
Have you tried another ESP yet, perhaps yours is just defective.
