Hi guys,

I bought a ESP32-WROOM-32 board and I try to connect the board to the wifi using ESPhome.

Below my yaml configuration :
‘’’

board: esp32dev

framework:

type: arduino

Enable logging

logger:

level: INFO

Enable Home Assistant API

Any Idea about this WIFI connection problem ?

Thanks in advance for your support :slight_smile:

4

Is your Wifi SSID 6Ghz, 5Ghz, 2. 4Ghz or mixed?

5

My Wifi is a 2.4 Ghz

6

Well ok that’s not it.

In this github ticket the op has the same issue you list (error is slightly different) but they ended up having to change thier config to specify the correct board type. In thier case a D1 mini. So when they edited the configuration for the correct board. It fired up.

Shot in the dark but it’s the only one I can find that’s remotely close.

I try it yesterday when I saw this page, but that was not better.

I try with hotspot on my phone and that works great. So I understand that comes from my internet box configuration.

Is there a specific configuration on it to do ?

Thanks for your support :wink:

I try with another smartphone and I have the same issue than with my internet box.
With internet box I try all the combination of settings but nothing works :confused:

But with my Galaxy samsung, the first try is the good one. I don’t understand what is the rootcause, that’s very strange !

I suspect a problem on my wifi channels.

No way, I try:

  • All channel.
  • To split my wifi 5GHz and 2.4GHz. And connect it on 2.4GHz
  • To connect without WPA2 password
  • Change WPA2 Personnal to WPA2/WPA Personnal Mixed Mode
  • Connect the board on battery

The only things works, It’s with a hotspot phone (OK with samsung but not with Iphone). I don’t understand what is different ?!

I don’t know what can I try more ?! Have you some ideas ?

I fix my problem, I reset my internet box with the factory configuration.

I configure it with ethernet cable,split two wifi network. One for 2.4GHz and another for 5GHz.

The two one are visible from any device now. I don’t know why but my 2.4GHz wifi was ghost, visible but not operationnal. I make a diagnostic and all were good, so I don’t understand but I am not a fan of HMI configuration boxes, that make what it wants to do.

Good to hear that splitting your wi-fi to separate 2.4GHz and 5GHz networks fixed your problem :slight_smile:

How many devices are connecting on 5GHz and how many on 2.4GHz ?

Wi-fi Access Points usually support only a fairly low number of devices - with popular home grade WAPs that number could be only 15 wireless devices. By moving your smartphones and other devices to 5GHz you have freed up some slots for devices using the older slower 2.4GHz bandwidth … but you will hit the limit again one day.

I am glad that you’ve fixed your issue… but unfortunately I don’t see what’s different between you solution and everything I have tested.

I am with a Ubiquiti Dream Router, a SSID for 2.4Ghz only and on only one AP (on channel 6) on an IOT vlan.

These are the settings that are on… (should be close to default): Proxy ARP, BSS Transition, UAPSD, Multicast Enhancement.

I even created a brand new 2.4 ssid only for esp32 but nothing changed.

One interesting thing: with the latest versions of ESPHome, it’s looping on the same errors… but with 2023.6.3 , after a while it connects … and stays on it

I solved with Wemos C3 mini with this config into Esphome
wifi:
ssid: SAxxxxxxxxxxxxxxxxxxx
password: xxxxxxxxxxxxxxxxxxxxxxx
output_power: 8.5

15

Thank you @Sdomotica_Automation but it’s already part of my config…

I also tried:
substitutions:
esphome_name: bt-gateway2

esphome:
name: ${esphome_name}
platform: ESP32
board: esp32dev
on_boot:
priority: 200
then:
- wait_until:
condition:
wifi.connected:
timeout: 5s

Had the same symptoms. (AVM Fritzbox, WROOM DevKit)
It seems to be the signal power. changing the “output_power:” parameter did not cut it.
I have plugged in the ESP directly into a Router USB port and have put it right onto the plastic router case.
immediate success.
