Powerline WiFi Extenders for Bringing Network Access to Another Room

One adapter connects to the router, and another uses the home's electrical wiring to carry network data to a different location. The second adapter may provide WiFi, Ethernet or both, depending on the kit.

It can be useful where wireless backhaul is weak but the electrical path works well. A regular extender is simpler when the router signal remains strong at a midpoint.

They may communicate across some circuits, but performance and compatibility vary with wiring, breakers and electrical noise. Follow the manufacturer's placement and pairing instructions.

Some kits include a WiFi access point in the remote adapter, while others offer only Ethernet. Check the included model's features and whether it supports the WiFi bands you need.
