D-Link’s DAP-1720 is easy to set up, offers a convenient mobile app for managing device settings, and can help fill an area with Wi-Fi. Handy features a built-in Ethernet port that can handle Gigabit speeds, and a physical on/off switch it an appropriate tool for extending the reach of your router. Still, it serves up patchy performance and is so large that it risks blocking adjacent AC outlets.
Despite some irregular performance, the D-Link DAP-1720 works particularly well when pushing signals to a floor below or above. That makes it one of the best Wi-Fi extenders available for getting signal to every floor of a multistory home, making it the perfect choice for anyone who finds their Wi-Fi signal dropping out when they go down or up the stairs.
Rather than being housed in a significant case with a separate AC adapter, D-Link's DAP-1720 plugs directly into an AC outlet. Like the Motorola MX1200, the DAP-1720 uses a two-prong plug built into the extender's back rather than a three-prong plug, like TP-Link RE650's, which can cause some problems in homes with old electrical wiring.
The 6.4 x 3.3 x 1.5-inch device is larger than Motorola's MX1200 but smaller than the RE650. It's a tight fit, and this extender might block an adjacent outlet. My advice is to plug it into the upper outlet and hope for the best.
The front of the DAP-1720 includes five LEDs: One at the top shows that the device is turned on and connected, while the four at the bottom serve as a signal-strength indicator to help guide your placement. The more green lights that are visible, the better the connection with the host router, while an amber or red light means the extender is disconnected or there's an operational error. Unlike with many other extenders, there's no way to turn the lights off.
