Common questions

Questions before you buy

Will an extender work through a basement ceiling?

It can, but floors and building materials affect signal strength. Place the extender where it still receives a reliable router connection.

Where should I place a basement extender?

Try an open area near the stairs between router and dead zone. Use the signal indicator or setup app to check that the router connection remains stable.

Is mesh or an extender better for a basement?

An extender can address one dead zone when its router link is sound. Mesh may be easier to manage across several floors or weak areas.

Can I wire a device to a basement extender?

Yes. TP-Link RE605X and RE550 list Gigabit Ethernet ports. Confirm the chosen model port and operating mode.
