THREE OF THE BEST WI–FI EXTENDERS

TP–Link RE450/AC1750 $99.99 tp-link.com

You can get cheap extenders for as little as $20, but it’s worth paying for one that provides decent performance. The RE450 provides dual–band 802.11ac Wi–Fi running at 1,750Mbps, plus one Ethernet port.

Linksys RE9000 $149.99 linksys.com

It may look like a regular router, but that’s the point — this tri–band extender has a 10,000sq ft range and offers speeds of up to 3,000Mbps — making it great for 4K video and gaming.

Netgear EAX20 $149.99 netgear.com

Netgear’s EAX20 is one of the first Wi–Fi 6 range extenders, and it will work with older 802.11ac routers too. It provides dual–band Wi–Fi at 1,800Mbps and has four Ethernet ports for additional wired connections.
