Start between the router and the weak area
An extender needs a viable connection back to the router. Put it along the route to the dead zone, rather than inside the spot with no signal.

Where to Place a WiFi Extender for Better Coverage
Place the extender between your router and the dead zone, where it can still receive a strong signal. Test more than one outlet.
Use the signal indicator
If your model has a signal light or app status, check it after plugging in. A weak backhaul link can limit the benefit in the room beyond it.
Account for walls and floors
Dense walls, metal surfaces, appliances and floor changes can weaken radio signals. Try an open outlet with fewer obstructions.
Compare the Wi-Fi bands
Where the extender offers both 2.4 GHz and 5 GHz, the bands trade reach and capacity differently. Follow setup guidance and test the devices you use.
Retest from the problem room
Check connection stability from the original dead zone. If performance remains inconsistent, try another outlet or a wired access point.
Common questions
Questions before you buy
Where should I put a Wi-Fi booster in a house?
Put it between the router and the weak-coverage area, in an open location where it still receives a good router signal.
Should a Wi-Fi extender be close to the router?
Close enough to maintain a reliable connection, but far enough toward the coverage gap to help there.
Can I put an extender upstairs?
Yes, if it maintains a suitable connection to the router. Test outlets near the stairwell first.
Does a Wi-Fi booster work through walls?
Signals can pass through some walls, but materials and thickness affect strength. An open, less obstructed position generally helps.
