Deco is app-managed mesh, not a conventional Archer web-router experience. The Deco app and TP-Link ID are central to ownership and configuration, while the main Deco is the unit linked to the modem.
What is specific to this product family?
| Ready for setup | A pulsing blue LED indicates setup readiness; solid blue means setup is in progress on commonly documented models. |
|---|---|
| Normal operation | Solid green or white indicates normal connection depending on model. |
| Fault indication | Red indicates lost Internet or another error. A red main Deco and red satellite require different diagnosis. |
| Reset behaviour | Official current guidance for common Deco units uses a brief one-second Reset press, followed by yellow and then pulsing blue. |
| Operating mode | Router mode provides NAT/DHCP; Access Point mode keeps the upstream router in control and changes availability of some features. |

Read model guide →Before using a generic fix
Check the model number, hardware revision and role of the device. A router and satellite from the same brand can use different firmware files and reset indicators. General advice is useful for diagnosis, but destructive steps must follow the product documentation.
