Thanks for reaching out. I understand that you are experiencing occasional connection drops on your Deco Mesh system and are considering performing a factory reset. You'd like to know whether you need to reset all three Deco units or just the main one.
Here’s how factory resetting works for Deco Mesh systems:
1. Resetting via the Deco app:
• Open the Deco app, tap the network map, and select the Deco unit you want to reset.
• Tap the three-dot icon in the upper right corner and select "Remove". As long as the Deco unit is online, removing it from the Deco network will restore it to factory default settings.
• Note: If you remove (reset) the main Deco, it will restore to factory defaults and this action will also delete the entire Deco network. This means all three nodes will be removed from your network, and you will need to set up the whole system again from scratch.
2. Resetting using the button on the Deco device:
• There is a small RESET button at the bottom of each Deco device. Use a pin to press and hold it for 1 second to restore that unit to factory default settings. The LED will flash yellow (resetting), turn solid yellow (booting up), then flash blue (ready for setup).
Summary for your situation:
• If you want to reset the entire system and start fresh, you can either remove the main Deco via the app or use the reset button on each unit.
• If you only reset the main Deco, the whole Deco network will be deleted, and all nodes will need to be set up again.
• If you only want to reset a specific unit (for example, if only one node is having issues), you can reset just that unit using the reset button or by removing it from the app.

Trouble resetting?
• You only need to briefly press the RESET button; a long press is not necessary. Try pressing the RESET button several times (brief press) until the LED indicator starts flashing yellow.
• The RESET function will not work when the Deco is showing a solid yellow light during startup. Please wait until the Deco has fully booted up before attempting to reset. If the Deco remains solid yellow after powering on, it may be bricked. In this case, please try firmware recovery or contact TP-Link Support.
If you have any further questions or need help with the setup process, feel free to ask!
