+Arduino boards and most IoT devices can only be used with 2.4 GHz band networks. The 2.4 GHz band offers better range and signal strength through obstacles compared to 5 GHz.

+
+## How to check if your network is 2.4 GHz {#about-network}
+
+Follow these steps to identify the frequency band of your Wi-Fi network.
+
+### Windows
+
+1. Open the settings menu in Windows and select the **Network and Internet** section.
+
+1. Under the wireless network settings, click on the **Hardware properties** link.
+
+1. A properties page will open. Here, you can find details about the wireless network, including the network band (GHz).
+
+### macOS
+
+1. Connect to the Wi-Fi network.
+
+1. Click on the Wi-Fi icon on the right side of the top navigation bar while holding down the Option/Alt key.
+
+1. Look for the entry starting with **Channel**. This will specify if the network is in the 2.4 GHz or 5 GHz band.
+
+---
+
+## Creating a 2.4 GHz network with a hotspot {#create-hotspot}
+
+If your network operates on the 5 GHz band, a quick solution is to create a 2.4 GHz network using the hotspot feature on an Android or iPhone device.
+
+### Android Devices
+
+1. Open the hotspot settings on your Android device.
+
+1. Look for an option similar to **Band** and select 2.4 GHz.

+
+For more information about sharing a mobile connection using a hotspot on Android, see [this guide](https://support.google.com/android/answer/9059108).
+
+### iPhone
+
+1. Open **Settings** and tap **Personal Hotspot**.
+
+1. Toggle Personal Hotspot on.
+
+1. If this option is displayed, tap on **Maximise Compatibility** to use a 2.4 GHz connection (iPhone 11 and earlier models automatically prioritize the 2.4 GHz band for hotspot connections).
+
+1. Edit the "Wi-Fi Password" if needed.
+
