Thanks for reaching out. I understand that you have several NAS drives with fixed IP addresses on your Deco Mesh network, and while you can access and use them normally, they do not appear in the Deco app's client list, even after rebooting your Deco system.

Here are some steps you can try to resolve this issue:

1. If the Deco app shows zero online client devices:
• After opening the Deco app, wait a few minutes to allow all devices to be detected.
• Reboot your main Deco unit.
• Make sure your Deco app is updated to the latest version available from Google Play or the App Store.

2. If some devices (like your NAS drives) are not shown as 'online' but are working fine:
• Ensure there are no other routers using the same Wi-Fi network name (SSID) as your Deco system.
• Check that your NAS drives are set to obtain their IP addresses automatically via DHCP, rather than using static IP settings. Devices with manually configured static IPs may sometimes not appear in the Deco app's client list.
• Reboot your entire Deco system to refresh the device list.

If none of these steps resolve the issue, please contact TP-Link support and provide the results of the troubleshooting steps above so we can assist you further.
