Boosters and extenders are the same thing: they repeat your router's signal, which is cheap but usually cuts speed and creates a second network. Mesh systems use several matched units that create one network and hand you over as you move. Wired access points, connected by network cable, give the best speed and are the right choice for thick-walled or multi-storey buildings and offices.
Key takeaways
- Booster = extender = repeater.
- Extenders are cheap but cut speed.
- Mesh gives one seamless network.
- Wired access points are fastest.
- Place extenders halfway, where signal is still good.

03Frequently asked questions
Do Wi-Fi boosters work?
Yes for a single weak spot, but most cut speed. They can't fix a bad internet connection.
Is mesh better than an extender?
Usually yes: one network, smarter roaming and better speed.
Where should I put an extender?
About halfway between the router and the dead zone, where signal is still strong.
