D-Link DAP-1620

Description

Wireless Interface

The wireless extender DAP-1620 is a portable device designed to increase the operational range of your wireless network. The extender supports operation with wireless devices of the standards 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac. DAP-1620 delivers reliable, high-speed wireless performance up to 867Mbps for 5GHz using the 802.11ac standard and up to 400Mbps for 2.4GHz. Simultaneous activity of 2.4GHz band and 5GHz band allows performing a wide range of tasks.

Secure Wireless Connection

The device supports multiple functions for the wireless interface: several security standards (WEP, WPA/WPA2), MAC address filtering, different operation modes (repeater, client, access point), WPS, WMM.

Advanced Capabilities of Wireless Network

The Super MESH¹ function allows to quickly connect multiple D-Link devices supporting Super MESH into one transport network, for example, when it's required to provide high-quality Wi-Fi coverage without dead zones in living units of complicated planning or it's needed to create a large temporary Wi-Fi network for an outdoor event.

Multi-user MIMO technology allows to distribute the extender's resources to let multiple wireless clients use the Wi-Fi network efficiently, keeping high rates for HD media streaming, lag-free gaming, and fast transfer of large files.

Transmit Beamforming technology allows to flexibly change the antennas' radiation pattern and to redistribute the signal directly to wireless devices connected to the extender.

Smart adjustment of Wi-Fi clients is useful for networks based on several D-Link access points or routers – when the smart adjustment function is configured on each of them, a client always connects to the access point (router, extender) with the highest signal level.

LAN Port

The wireless extender is equipped with one Gigabit Ethernet LAN port, which can be used to connect a wired client to the extender or to connect DAP-1620 to a wired router.

Signal Strength LED

The LED clearly shows the signal level of the wireless network to which DAP-1620 is connected. Due to this, you can easily find the best location for the extender.

Security

The SSH protocol support provides more secure remote configuration and management of the extender due to encryption of all transmitted traffic, including passwords.

Now the schedules are also implemented; they can be applied to MAC filter rules and used to reboot the extender at the specified time or every specified time period and to enable/disable the wireless network.

Easy Configuration and Update

You can configure the settings of the DAP-1620 device via the user-friendly web-based interface (the interface is available in several languages).

The configuration wizard allows you to quickly switch the extender to the access point, repeater, or client mode and configure all needed settings for the selected mode in several simple steps.

You can simply update the firmware: when the Internet access is provided, the extender itself finds approved firmware on D-Link update server and notifies when ready to install it.

Repeater Mode

You can connect DAP-1620 in the repeater mode to a wireless router for extending the range of the existing wireless network.

Client Mode

In the client mode, you can let a wired PC connected to DAP-1620 access the network of a wireless router.

Access Point Mode

You can connect DAP-1620 in the access point mode to a wired router for adding a wireless network to the existing local network.

¹Super MESH is not compatible with EasyMESH. Super MESH can be unavailable in some FW versions (for the latest data, please refer to the page of the relevant device).

¹Maximum wireless signal rate is derived from IEEE standard 802.11ac and 802.11n specifications. In order to get the rate of 400Mbps in the 2.4GHz band, a Wi-Fi client should support MIMO 2x2 and QAM256 modulation scheme. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate. Environmental factors will adversely affect wireless signal range.
