Overview
A Deco mesh owner with a dead zone gets a satellite that plugs straight into a wall outlet and joins the existing network. It uses the home's electrical wiring together with Wi-Fi to carry the signal, then broadcasts dual band Wi-Fi in that room.
Plugging into an outlet makes it simple to fill a garage, basement or far bedroom with signal. It does nothing without a main Deco unit, and the older Wi-Fi standard caps speed.
Who it's for
Homes already running Deco mesh that struggle in one corner will close the gap quickly. Households with another router brand cannot use it at all.
Pros and cons
- Plugs into any outlet
- Wired backhaul over home wiring
- Joins the mesh automatically
- Ethernet port for a wired device
- Only works with Deco systems
- Older Wi-Fi standard
- Powerline speed depends on home wiring
Performance notes
Throughput depends on the electrical wiring between outlets, since the powerline link carries data alongside Wi-Fi back to the main unit. Devices then roam between Deco units automatically, choosing the strongest connection as you move.
