Check the extender and router instructions
Confirm the extender is compatible with your router's WiFi and note its reset and WPS controls. If you are replacing an old extender, reset it first when its instructions recommend doing so.

How Do I Hook Up a WiFi Extender to My Router?
Connect the extender to your router with WPS or its setup app, then move it to a midway spot where it still receives a good signal. Test the room you want to cover before settling on a position.
Connect with WPS
Plug the extender in near the router. Press WPS on the router, then press the extender's WPS button within the time stated in its manual. Wait for its connection indicator; button sequences and indicator meanings vary by model.
Use the setup app or web page if needed
If either device lacks WPS, or pairing fails, open the extender's official app or setup page and follow its prompts. Select your home network, enter its WiFi password carefully and complete any band or network-name choices shown.
Choose a position between router and dead zone
Move the paired extender roughly along the route to the weak-signal room, but keep it where the router signal is still usable. A signal indicator or the manufacturer's app can help; thick walls, metal and appliances can interfere.
Check the extended connection
Connect a phone or laptop to the extended network and try the places where coverage was poor. If the link is unstable, move the extender closer to the router, avoid an obstructed socket and repeat the check.
What if the extender will not connect?
Check the WiFi password, restart both devices and repeat setup near the router. Confirm the router is broadcasting the band the extender expects and consult its manual for a reset procedure or firmware guidance.
Common questions
Questions before you buy
Can I hook up a WiFi extender without WPS?
Yes. Use the manufacturer's app or web setup page to select your WiFi network and enter its password. The exact menus depend on the model.
Where should I plug in a WiFi extender?
Start near the router for setup, then place it between the router and the weak-coverage area while it can still receive a usable signal.
Do I need to change my WiFi password?
Usually you enter the existing router password during setup. Follow the extender's prompts for whether it copies the network name or creates an extended one.
Why is my extender connected but the internet slow?
An extender can only repeat the connection it receives, and the wireless link may be weakened by distance or obstacles. Try a position nearer the router and compare performance in the target room.
