A Wi-Fi extender is a gadget that sucks in a Wi-Fi signal, and then spits it back out on the same network name and frequency. Think of it as a radio repeater, because that’s essentially what it is.
It’s a relatively easy and inexpensive way to extend your network into those hard-to-reach spots in your home, and it’s much less expensive than a full mesh system (go. pcworld.com/mshs). But setting it up isn’t always a straightforward process. Here are some basic tips on how to get started, and advice on how to make the most of these handy devices.
BUYING THE RIGHT WI-FI EXTENDER
When buying a Wi-Fi extender, you want to make the most out of the connection you already have. So check your current Wi-Fi router—either the one you got from your ISP, or the one you bought yourself and connected to the modem.
You’re going to want to match two values between the router you have and the extender you want to buy: the Wi-Fi generation and the Wi-Fi speed. The generation will generally be either Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax; go.pcworld.com/wfax). The speed is expressed as a function of that connection: If the extender is marked as AC750, that means it’s using 802.11ac at up to 750 megabits per second. If it says AX1800, it’s using 802.11ax at up to 1800 megabits (1.8 gigabits).
You can buy an extender that’s newer and/or faster than your router, and it will work fine. But you’ll be paying for something you don’t really need, since the extender won’t be able to speed up the connection from the router itself.
