TP-Link’s RE220 is a cheap way to add more reliable Wi-Fi coverage and an Ethernet port to a part of your home if you already have a router and a wireless network.

The TP-Link RE220 is one of our favorite extenders we tested. Set up is made easy with a QR code on the box that links to the app and guides you through a setup that takes mere minutes. We love its stylish look and the fact that it's no larger than the average air freshener or night light. Despite its size and aesthetics, the RE-220 has still managed to fit in an ethernet port, which is fantastic. 
Though the RE-220 has an excellent range for home use, we'd recommend choosing a model that projects a signal over more extensive square footage for businesses or special events. On that note, it's not the fastest repeater. If you're looking to get maximum Mbps for gaming or an office, look for a faster model. Despite that, we still think it's great for most applications.

The TP-Link RE605X is a bit pricier than our main pick, but it’s a good choice if more speed and increased reliability are the most important factors to you.
