Not all Deco models allow manual updates in the app. Some TP-Link Decos will download and update firmware automatically overnight—no action needed. If you don’t see a manual update option, check TP-Link’s official website for your Deco model info and possible firmware files.

If the Update Fails (Or You Get Stuck)

• Update gets stuck or LED blinks for 15+ minutes:
  • Wait a little longer; larger updates may take time.
  • Restart the affected Deco by unplugging/replugging the power.
  • Try starting the update again via the Deco app.
• No manual update option in the app:
  • Don’t worry—your Deco might be one that updates in the background automatically.
  • Visit the TP-Link Deco support page and enter your exact model to check for manual update files or instructions.
• Unit unresponsive after update:
  • Try a soft reset via the app or physical reset (hold button for 10 seconds).
  • Re-add the unit in the Deco app if it drops offline.
• Can’t update old firmware:
  • Make sure the app and your phone/tablet’s OS are updated.
  • Confirm your internet connection is stable.
