You can write and upload sketches on Chrome OS with the Cloud Editor in Arduino Cloud. The Cloud Editor has an extensive feature set similar to the desktop IDE. While many popular boards are compatible, you should check [the list of compatible boards here](https://support.arduino.cc/hc/en-us/articles/360014779899).

## Troubleshooting
78
+
79
+
* Make sure your device is connected using a functional data USB cable and that one or more LEDs on the board are lit.
80
+
* Even if no board is detected, try clicking the Upload button to open the **Authorise USB connection** prompt.
81
+
* Make sure you’re using the [Arduino Cloud for Chromebook](https://play.google.com/store/apps/details?id=cc.arduino.create_editor) app, **not** the Arduino Create for Education Chrome app.
82
+
* Verify that the board is [compatible](https://support.arduino.cc/hc/en-us/articles/360014779899-Boards-compatible-with-the-Web-Editor).
83
+
* If you're using either **Nano RP2040 Connect** or **UNO WiFi Rev2**, please follow the special [setup instructions](https://support.arduino.cc/hc/en-us/articles/360014779899-Boards-compatible-with-the-Cloud-Editor#chromebook) for those boards.
84
+
* Ensure that the board is not [counterfeit](https://support.arduino.cc/hc/en-us/articles/360020652100-How-to-spot-a-counterfeit-Arduino).

## Using Arduino Cloud on school networks
28
+
29
+
Internet access in Schools can vary depending on the end user, device type, and the Wi-Fi network type you have installed in schools. Most schools today are switching to using a WEP2-Enterprise network as a safe and secure way to access the internet for students, teachers, and other staff.
30
+
31
+
Setting up Arduino to access the internet via the school network can be challenging. This guide aims to walk you through the steps to connect your Arduino board to the school network and access our IoT features.
32
+
33
+
The WPA2 (Enterprise) RADIUS combination affords networks the highest level of cybersecurity, especially when X.509 digital certificates are used for authentication. WPA2 Enterprise requires an 802.1X authentication server anyway, so it's only logical to implement the best possible authentication security during configuration. However, WPA2 - Enterprise **doesn't work with Arduino Devices**.
34
+
35
+
**Try this if you're having issues using Arduino Cloud on a school network:**
36
+
37
+
* Find out the type of Wi-Fi network implemented on your school premises. If you are using any sort of WEP/WEP2 personal networks in your school besides the main network that essentially only requires an SSID (the name of the Wi-Fi connection) and password, you are good to go.
38
+
39
+
* Reach out to your school administrator and recommend creating a subnetwork specifically for connecting your Arduino devices using WEP/WEP2. This network would have limited access and can only be used for IoT purposes.
40
+
41
+
* If you don't have access to or can't create a separate WEP/WEP2 network, you can create a hotspot using your mobile device and try to connect your devices to it. Keep in mind that this solution is temporary and restrictive, primarily suitable for testing purposes. It's not intended for prolonged deployment.

> Device status is not supported by the LoRa protocol, see [About device status in Arduino Cloud](https://support.arduino.cc/hc/en-us/articles/4407169649682-About-device-status-in-IoT-Cloud).
8
+
9
+
1. Go to the [Devices tab](https://app.arduino.cc/devices) and verify that your device has an associated Thing. If not, you must either create and new Thing or associate an existing Thing with the device.
10
+
11
+
12
+
13
+
2. Go to the [Things tab](https://app.arduino.cc/things) and open the Thing that's associated with your device. Then go to the [Devices tab](https://app.arduino.cc/devices), and find your device in the list. Under **Network**, click on **Change** and verify that your credentials are correct.
14
+
15
+
***Wi-Fi:** Make sure the name (also called _SSID_) and password (also called _encryption key_ or just _key_) are correct. The password can be revealed by clicking the eye symbol. If you don't know your network name or password, contact your network administrator or the manufacturer of your Wi-Fi access point. If your device has a secret key, make sure it's entered correctly (if you're unsure, remove and re-add the device to generate a new key).
16
+
***Arduino SIM:**[Use these credentials](https://support.arduino.cc/hc/en-us/articles/360013825159). Make sure a working GSM antenna is connected to the board and that an Arduino SIM plan is activated with [your account](https://store.arduino.cc/digital/subscriptions/plans).
17
+
18
+
3. Open the Thing's **Sketch tab**. Make sure the right device is selected and re-upload the sketch.
19
+
20
+
21
+
22
+
4. Fully [delete the device](https://support.arduino.cc/hc/en-us/articles/360018324700), then add it again as a new device. For detailed instructions, see [Add and connect a device to Arduino Cloud](https://support.arduino.cc/hc/en-us/articles/360016495559).
23
+
24
+
5. Test your setup with an example from the [ArduinoIoTCloud library](https://www.arduino.cc/reference/en/libraries/arduinoiotcloud/). Upload using Arduino IDE or the [Cloud Editor](https://create.arduino.cc/editor).
25
+
26
+
6. Check your device's power supply. Avoid using a USB hub, and instead connect the board directly to a USB port or another power source with a reliable cable to ensure sufficient power.
