Promethean Board Not Working? Quick Fixes for Wi-Fi, Google Drive, and Loading Issues

Promethean panels sometimes lose their internet connection, stop syncing with Google Drive, or become slow. Here are the most common fixes.

Panel Won't Connect to Wi-Fi or the Internet

1. Restart the panel — not just the screen. Use the power button on the back/bottom of the panel. Hold it down until the panel fully shuts off, wait 10 seconds, then turn it back on.
2. Once rebooted, check the Wi-Fi settings (swipe down from the top of the panel to access the quick settings menu) and confirm it's connected to the correct campus network.
3. If the network doesn't appear, try manually selecting it from the available networks list.
4. If it still won't connect, check if other devices in the room have internet. If nothing has internet, the issue may be a campus network outage — contact IT.

"Can't Refresh" Error for Google Slides or Drive

If Google Slides or Drive shows "Can't refresh. Check your network and try again":

1. Clear the browser cache on the panel:
   • Open the Promethean browser (Chrome).
   • Tap the three-dot menu > Settings > Privacy > Clear browsing data.
   • Select Cached images and files and Cookies. Clear them.
2. Sign out and back into your Google account on the panel.
3. Restart the panel (full power cycle, not just sleep).
4. If Drive says "Sync is off," go to Drive settings on the panel and re-enable sync.

Panel Is Slow or Takes Forever to Load

1. Close unused apps. Too many open apps slow down the panel.
2. Clear the cache (see steps above).
3. Restart the panel. Panels that haven't been restarted in weeks will accumulate performance issues.
4. Avoid opening heavy websites or multiple video streams simultaneously.
