How to Choose

Match your router

Use the same WiFi generation as your router for the best results.

Placement

Put the extender halfway between the router and the dead zone, where it still gets a strong signal.

Wired option

If you can, run Ethernet. A wired link is faster and more stable than any extender.

Frequently Asked Questions

Does an extender slow my WiFi?

Single-radio extenders can cut speed because they use the same radio to talk to the router and to your devices.

Extender or mesh?

Mesh systems manage handoff better but cost more. See our guide to compare.

Where do I plug it in?

Halfway between the router and the weak area, in a spot with decent signal.

Bottom Line

For a wired device, the TP-Link RE220 or RE615X.
