Quickstart connect not working! ESP32

I am trying to connect my first Quickstart device, I used the quickstart tour, just pasted mi WiFi SSID and password and copied and pasted the code in Arduino IDE, uploaded to ESP32 and it doesn’t connect :sob: The output I get on the Serial monitor is:

¿May I have some help please? Thanks!

Are you trying to connect to a 5GHz network?

Hello, @Pachagaia

Also try in Blynk.begin use you server.

for example fra1 server

Blynk.begin(auth, ssid, pass, "fra1.blynk.cloud");

If you see in the browser only blynk.cloud and don’t know your server. Look at the region in the lower right corner of the screen.

It’s failing to connect to your WiFi network.
The SSID suggests that this is a 5GHz network. The ESP32 doesn’t support 5GHz networks, only 2.4GHz

Pete.

Hi Pete,
Thank you very much, today I will try with the other network with I guess is 2.4GHz. Thanks a lot!!!

Bernardo

Hi John93, yes, today I will try to connect to the other network of the same modem/router. Pete told me the ESP32 doesn’t support 5GHz. Thanks for your response!!!

Hi Oleksii-QA,
I just tried connecting to the normal(not 5 Ghz) network from my router and it works! That was the problem. Nevertheless thanks a lot for the help!!!

I just connected to the normal network(not 5GHz) an it worked! Thanks for the help!!!
