Thanks for reaching out. I understand that your Deco app is showing all your satellite units as offline, even though the LEDs on the satellites are green and your mesh network appears to be working. However, you also mentioned that your network is unstable and frequently disconnects.

When the Deco satellite units display a green or white LED, it usually means they are functioning properly and have a good internet connection. If the app still shows them as 'offline', this is likely a display issue within the app. However, since you are also experiencing instability, let's address both the app display and the network stability:

1. Confirm Satellite Connectivity:
• Move a device (like your phone or laptop) close to a satellite Deco unit and connect to its Wi-Fi or Ethernet port.
• Check if you have stable internet access when connected directly to the satellite.

2. Reboot the Main Deco:
• Power cycle (reboot) your main Deco unit. This can often resolve both app display errors and temporary network instability.

3. Update Firmware:
• In the Deco app, go to MORE > System > Firmware Update and make sure all Deco units are running the latest firmware.

4. Update the Deco App:
• Open Google Play or the App Store on your phone and ensure the Deco app is updated to the latest version.

If the app still incorrectly shows your satellites as offline, but the LEDs remain green/white and your devices have internet access, it's likely just a display issue. However, if the network instability continues even after these steps, there may be a deeper connectivity or interference issue.

If the problem persists, please contact TP-Link support and provide the results of the above troubleshooting steps. This will help us further diagnose and resolve your issue.
