ESP32 won't connect to home WiFi, but connects to hotspot

I recently acquired an ESP32 Arduino-Style board, and intend on using it with my home wifi. However, after doing a very simple initial test with some tutorial code I found online, I found that the board will simply loop forever, unable to connect to my home wifi. I have rigorously checked that I am using the correct SSID and password. In addition, I have found that the ESP32 connects just fine to a mobile hotspot. The simple example code is below:
Code: Select all
#include <WiFi.h>
const char* ssid = "REDACTED";
const char* password = "REDACTED";
void setup() {
Serial.begin(115200);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.println("Connecting to WiFi..");
}
Serial.println("Connected to the WiFi network");
}
void loop() {
}

The ESP32 only supports 2.4GHz wifi.

This shouldn't be an issue as my home wifi has both 2.4 and 5 ghz bands?

That isn't the problem,
My home internet has both 5.0GHz and 2.4 GHz bands. But since you said that I even tried making them separate networks and only connecting the esp32 to the 2.4GHz one - I am still unable to connect.

Does your SSID or password have special characters? Password over 8 characters? WPA2-PSK? Do you have multiple access points with the same SSID? Restarted the router? Using MAC address filtering on router and forgot?

The password has an asterisk and 9 characters. Is this an issue? I have checked every setting on the router, im certain it is not using MAC address filtering. But if the above password issues are a problem then that could well be it.
EDIT: Well, I changed the name of the 2.4 channel to something short and different from 5.0. then I set the password to 8 characters all lowercase alpha. Still I am getting the same result sadly. I'm starting to think maybe I should just buy a raspberry pi and plug it in to my router and then use it as an access point for the ESP. Ugh.

What brand is your router? I'm having the same issue but only with TP-Link routers. I tried both hotspots and different brands of routers and it works fine, only with TP-Link I get this problem and havne't been able to solve

I have same problem like that when i try to connect my TP-LINK router with C code it work. and after that i make only two changes for making c++ program
extern "C" void app_main(void)
before main function
and change file name from main.c to main.cpp
program compile upload success
and debug log show connected to router
but can't get IP from router

Has anyone found a solution to this issue? I'm using a esp32-wroom-ud dev board with the Arduino IDE. I can connect with no problem to a hot spot I created with my cell phone but I cannot connect to my home wifi network. I have verified my password is correct; I'm using 2.4g and the wifi signal strength is excellent. Thanks for any suggestions...
