PowerLine Network Adapters

Powerline adapters carry a network connection over the existing mains wiring in a building. They are the practical answer where running Ethernet is not possible — listed buildings, leased offices, a back room the Wi-Fi will not reach.

Buying guide ↓

Buy a kit, not a single adapter

Powerline needs at least two units: one at the router and one at the far end. Kits are sold in pairs and are the normal starting point. Single adapters are for adding a third or fourth point to a network you already have, and they must be from a compatible standard.

Speed ratings and what they mean in practice

Ratings here run from AV1000 through AV1300 and AV2000 to G.hn2400. These are theoretical maximums for the powerline link itself and real throughput is always lower — the wiring, its age and the distance between sockets all matter. Treat the number as a way to rank models rather than a speed you will measure.

Passthrough, Wi-Fi and port count

A passthrough model has a socket on its face, so it does not cost you a wall socket. Adapters without one will block the outlet they use. Wi-Fi models add an access point at the far end, which is what you want for a room with no wired devices; LAN-only models are simpler and suit a single desk or a printer. Multi-port models give two or three Ethernet sockets at the far end.

One constant: plug powerline adapters straight into the wall. Extension leads and surge strips filter the signal and are the most common reason a powerline link underperforms.
