Some ESP devices have an issue connecting to dual band routers #1

I found the issue noticed by many that some random number of ESP devices don't connect well to dual band routers. Looping through Wifi.begin() seems to help significantly. I made this code change in two places inside of WiFI Provisioner and have not had a problem since. Moving the Wifi.begin inside of the While not connected loop, before the delay, and timeout check. Save for ConnectToWiFi and connectToExistingWiFINetwork functions.

while (WiFi.status() != WL_CONNECTED) { if (storedPassword.isEmpty()) { WiFi.begin(storedSSID.c_str()); } else { WiFi.begin(storedSSID.c_str(), storedPassword.c_str()); }
delay(wifiDelay); // Check if the connection timeout is reached if (connectionTimeout != 0 && millis() >= startTime) { WiFi.disconnect(); delay(wifiDelay); debugPrintln( "Connection timeout reached, continuing to start the provision"); return false; } }
