Fix Panel ID Error — Promethean Screen Share Disconnections

Overview

If you are repeatedly kicked off Promethean Screen Share or see a Panel ID Error, the issue is usually caused by a Wi-Fi or sleep settings conflict. Follow the steps below to diagnose and resolve the problem.

Check Wi-Fi Connection

1. Verify your PC is connected to the RCS Devices Wi-Fi network (not a guest network).
2. Verify the Promethean panel is also connected to Wi-Fi — check the panel's status bar or network settings.
3. Ensure Windows Updates are current, including Advanced Settings (optional updates), which often include Wi-Fi driver updates.

Adjust Sleep Settings

1. On your PC, go to Settings → System → Power & Sleep.
2. Set the sleep timer to a value longer than your class period (e.g., 2 hours or "Never" while plugged in).
3. If sleep settings have reverted to default, re-apply them and also check your group policy or power plan settings.

Update the ActivInspire / Screen Share Software

1. Open the Promethean Screen Share app on your PC.
2. Check for available updates and install any pending version.
3. Restart the application and reconnect using the Panel ID displayed on the Promethean screen.

Still Disconnecting? Try This

• Restart both the PC and the Promethean panel.
• Re-enter the Panel ID shown on the panel screen — IDs refresh after a restart.
• If the panel ID still shows an error, submit an IT ticket for a hands-on check.
