Hello all. I bought a genuine Arduino Uno R4 WiFi which I could connect to a Wifi network on January 22nd, while I was away from home. I tested the sketch generated by the Arduino IoT Cloud Thing which switches on and off the built-in LED according to a switch widget created in a dashboard and ev…

[image] c_penant2023-new: Are there constraints on the password ? The presence of \ (backslash) or " (double quotes) characters can be problematic. It is possible to use passwords that contain these characters, but they must be properly escaped, and the escaping requirements are more complex …

Thank you very much for your kind help. With what you wrote, the issue does not come from the password. What is strange is that the board gets easily connected to my phone, set as a wifi access point to the network, and not directly to the network. Regards.

I face the same problem. My R4 connects to my mobile hotspot but not to my home network. I have a dual band WiFi Router . So far I have been using 5 GHZ. After finding out that R4 connects only to 2.4 GHz I created a new SSID on my router for 2.4GHz and used a simple password without any special cha…

Your 2.4Ghz Wifi´'s SSID and password should not be too long or have special characters. Check/Review also your router's wifi security settings. Try using the same settings you used for your hotspot wifi.

@silentobserver Have not observed that. For this poster, there is something about his router's wifi he needs to fix.

Firmware updated. Password is very simple. No issues. But it does not connect. All other devices in my home connect properly. I feel Arduino should do something so that R4 connects to any WiFi network seamlessly.

Blockquote [image] ptillisch: I would expect it is the same as the limits imposed by the Wi-Fi framework (e.g., 63 characters for WPA2 ). I just tried a 50 character password and it worked fine. Sorry but this ist not ture @ptillisch . If I use a 50 Char password and fill it with special ch…

[image] cdr_chakotay: and fill it with special chars Why would you do that when you are attempting to disprove my claim that 50 character passwords are supported? It is at least equally possible that your result was caused by the inclusion of the "special chars" rather than the length of the …

Could this be a region issue?

Some channels (frequencies) are not allowed in some regions.
Maybe UNO R4 WiFi avoids some channels?
