Power the extender beside the router
Choose a nearby socket for initial pairing and wait for the power indicator described in the manual. Avoid using a distant room during setup; a weak first link can make onboarding fail.

How to Connect a Wi-Fi Extender to a Router
Pair the extender while it is near the router, then relocate it only after setup confirms a working connection.
Choose an available pairing method
Use the maker app or browser setup for clear prompts. WPS can be quicker when both router and extender support it: press the router button, then follow the extender timing instructions.
Select the correct router network
If the setup screen lists separate 2.4 GHz and 5 GHz networks, select the band or bands supported by the extender. Enter the router Wi-Fi password carefully; this is not necessarily the admin password printed for the router interface.
Wait for confirmation before relocating
Let the extender apply its settings and check the status light or app for a successful router link. If setup reports a weak signal, stay close and resolve pairing before trying another socket.
Move it towards the coverage gap
Unplug the unit and place it between the router and the room that needs better reception. Keep it within reliable router range and away from enclosed cabinets or large metal objects.
Common questions
Questions before you buy
How do I connect a Wi-Fi booster to my router without WPS?
Use the manufacturer app or browser setup page, join the extender’s temporary network if prompted, then choose your home Wi-Fi and enter its password.
Should I connect the extender to 2.4 GHz or 5 GHz?
Follow the model’s setup guidance and choose the band that suits reach and capacity. Some extenders can connect to both bands; others have different limitations.
Why can’t my phone find the extender during setup?
Check that the extender has powered on and that your phone is connected to its temporary setup network if the app requests it. Restart the setup flow if discovery still fails.
Can an extender connect to a router from another provider?
Usually a standard Wi-Fi extender can join a compatible router regardless of broadband provider. Provider mesh features may require matching equipment.
