Using a WiFi Extender with an Old Router: What to Check

Often, yes, if the extender supports a Wi-Fi standard and security mode that the router can use. Check both manufacturers' compatibility and setup guidance, especially if the router only supports older bands or security settings.

A standard Wi-Fi extender does not send your network through electrical wiring. For that, use a compatible powerline kit with adapters connected to the same electrical installation; performance can depend on the wiring and circuit layout.

Many models can be configured through a phone app or web interface instead of WPS. Check the model's instructions and make sure you can access the router's network name and password.

Place it where the router's signal is still usable, between the router and the weak-coverage area. Putting it inside the dead zone gives it little signal to repeat; use the manufacturer's signal indicator or setup app to help find a suitable spot.
