CHAPTER 2. OVERVIEW
General Information
The DIR-620S device is a wireless router supporting 3G/LTE with a built-in 4-port switch. It
provides a fast and simple way to create a wireless and wired network at home or in an office.
You are able to connect the wireless router DIR-620S to a cable or DSL modem or to a private
Ethernet line and use a high-speed Internet connection to successfully fulfill a wide range of
professional tasks. The built-in 4-port switch enables you to connect Ethernet-enabled computers,
game consoles, and other devices to your network.
The router is equipped with a USB port for connecting a USB modem, which can be used to
establish connection to the Internet. In addition, to the USB port of the router you can connect a
USB storage device, which will be used as a network drive, or a printer.
In order to use the multifunction USB port effectively, the router supports simultaneous operation of
several USB devices. For example, you can access multimedia content of the connected HDD
storage and at the same time share a USB printer.

You can use any Ethernet port of the router as LAN or WAN port. The new-generation firmware
supports assigning several WAN ports, for example, in order to configure the primary and backup
WAN connection of different ISPs. In addition, you can configure the WAN failover using a 3G/4G
modem.
Using the DIR-620S device, you are able to quickly create a wireless network at home or in your
office, which lets computers and mobile devices access the Internet virtually anywhere (within the
operational range of your wireless network). The router can operate as a base station for connecting
wireless devices of the standards 802.11b, 802.11g, and 802.11n (at the wireless connection rate up
to 300Mbps).
The router supports multiple functions for the wireless interface: several security standards (WEP,
WPA/WPA2), MAC address filtering, WPS, WMM.
In addition, the device is equipped with a button for switching the Wi-Fi network off/on. If needed,
for example, when you leave home, you can easily switch the router’s WLAN by pressing the
button, and devices connected to the LAN ports of the router will stay online.
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) with the highest signal level.
Support of guest Wi-Fi network allows you to create a separate wireless network with individual
security settings. Devices connected to the guest network will be able to access the Internet, but will
be isolated from the devices and resources of the router's LAN.
The wireless router DIR-620S includes a built-in firewall. The advanced security functions
minimize threats of hacker attacks, prevent unwanted intrusions to your network, and block access
to unwanted websites for users of your LAN.
