ESP32 is not connecting to a specific WiFi router?

Projects Programming
1

I have two routers in my house, and i want my esp32 to be able to connect to both (not at the same time) but i realise that esp32 cannot connect to one of them for any reason. I have tested a code for wifi connection tests and it works in the other one.

The only thing i didnt check is the router configuration, is there any config that can lead to this behaviour?

Does the SSID of the problem outer have any non alphanumeric characters in its name ?

What WiFi band does it use ?
2.4 GHz, 5 GHz or both ?

3

both have alphanumeric characters and both are 2.4Ghz

Did you check if the range is just to high or maybe if there are too many different wireless communications (WLAN+Bluetooth or similar), which interfere?

5

Did you give your ESP an IP address that conflicts with one on problem router?

posting your code would help a lot
You can post code by using this method that adds the code-tags
There is an automatic function for doing this in the Arduino-IDE
just three steps

  1. press Ctrl-T for autoformatting your code
  2. do a rightclick with the mouse and choose "copy for forum"
  3. paste clipboard into write-window of a posting

best regards Stefan
