 With this method, you can access your UNO Q from any machine in your local network. This allows you to use Arduino App Lab as if you were connected directly to the board, where you can develop & run Apps in the same way as if it was connected via USB-C®.
 
+Network Mode relies on **local network discovery (mDNS)** to automatically find boards on the same network. Some network configurations such as guest Wi-Fi, corporate or IoT networks, VPNs, or strict firewall rules may prevent automatic discovery, even if the board is connected to Wi-Fi.

+**Note**  
+Being able to access the board via browser, SSH, or IP address does not guarantee that it will appear in Network Mode. Arduino App Lab uses local network discovery to list boards automatically.

 ### Hello World Example
 
 Let’s program the UNO Q with the classic **Hello World** example typical of the Arduino ecosystem: the Blink sketch. We will use this example to verify that the board is correctly connected to the Arduino App Lab.
