Hi everyone,

I have a home network with 10 Deco units all running in Access Point Mode: 6 × Deco M5 and 4 × Deco X60. Everything worked fine for a long time until one of the X60 units started to behave strangely.

Symptom #1 – X60 offline with green LED

- In the Deco app this X60 suddenly showed as “offline”.
- The LED on the unit stayed solid green.
- All clients connected to this X60 lost internet access, while clients on the other Decos worked normally.
- Several normal reboots did not fix it.

Symptom #2 – M5 names reverting

Around the same time, three of my M5 units started losing their custom names in the app. The app sometimes shows them only as “M5”. If the node goes offline for a moment, the custom name comes back, but later it reverts again to “M5”. This is only cosmetic, but I mention it in case it is related.

Factory reset of the problematic X60

Because the X60 stayed offline in the app, I performed a hardware factory reset:

- Pressed and held the reset button on the bottom for about 15 seconds,
- LED turned yellow and then started blinking blue.

Since then I have not been able to add this X60 back to any network.

What happens now

- When in setup mode, the X60 broadcasts its default SSID `Deco_A3F8` (from the sticker).
- I can see and join `Deco_A3F8` from my iPhone without issues.
- However, the Deco app always shows the message “We couldn’t find any new Deco”.

I get exactly the same message in all of these scenarios:

1. Trying to add the X60 as a new node to my existing mesh (X60 placed about 1 meter away from the main Deco and also tested with Ethernet between them).
2. Trying to use this X60 as the main router, connected directly to the modem and using “Create a new network” in the app.

So at the moment I have:

- 3 × Deco X60 and 6 × Deco M5 working normally in Access Point Mode.
- 1 × Deco X60 V3.0 that powers on and broadcasts `Deco_A3F8`, but the Deco app (latest iOS version) never discovers it as a new device.

Questions

- Could this X60 be stuck as “bound” to my previous network/account in the TP-Link cloud and therefore not adoptable again?
- Is there any way for support to check its status from your side or to unbind / reset it remotely?
- From your experience, do these symptoms point to a hardware failure and should I consider an RMA?

Device details

- Model: Deco X60 (US)
- Hardware Version: V3.0
- Default SSID: Deco_A3F8
- App: Deco for iOS on iPhone

I can upload screenshots if needed (offline X60 with green LED, error message “We couldn’t find any new Deco”, Wi-Fi list showing the Deco_A3F8 SSID, etc.).

Thanks in advance,
Gaston
