What does a WiFi range extender do?
It connects to your existing router over WiFi and rebroadcasts that network from another point. Devices nearby can then use the rebroadcast signal, subject to the quality of the extender's link back to the router.

What Does a WiFi Range Extender Do in a Home Network?
A WiFi range extender receives an existing wireless signal and rebroadcasts it to improve coverage in another area. It can help with a coverage gap, but it does not create a faster internet plan or repair a weak source connection.
How does a WiFi booster differ from a router?
A booster or extender is an addition to the existing network. A router directs traffic between your home devices and internet connection; the extender relays the router's wireless access into a harder-to-reach area.
Does an extender increase internet speed?
It does not increase the speed delivered by your provider. It may improve a device's connection where the router's signal was weak, but each wireless hop and local conditions can affect throughput.
Where does a range extender work best?
It needs to sit within usable coverage from the router and close enough to the area that needs better reception. Putting it at the far edge of a dead zone leaves little signal to relay.
When is mesh or powerline a better fit?
A mesh system coordinates compatible nodes as one network, while a powerline kit sends traffic between adapters over electrical wiring. Consider these when roaming or the wireless path to the extender is unreliable.
Common questions
Questions before you buy
What does a WiFi booster do?
The term usually refers to a repeater or range extender that relays an existing WiFi signal to reach an area with weak coverage. It does not improve the underlying internet service speed.
Does a WiFi extender make WiFi reach farther?
It can extend coverage from the location where it receives the router's signal. The result depends on placement, building materials, interference and the extender's capabilities.
Can a WiFi extender fix slow internet?
Only if the slow experience is caused by poor wireless coverage in a particular area. It will not fix a slow broadband connection, network congestion or an overloaded router.
Do WiFi extenders work with any router?
Many are designed to work with standard WiFi routers, but supported bands, security settings and mesh features vary. Check the exact extender and router specifications before buying.
