Description

ADSL port and 4-port switch
ADSL router is equipped with a port for connecting to ADSL line. Built-in 4-port switch allows you to connect computers equipped with Ethernet adapters, game consoles and other devices to your network. In addition, any Ethernet port of the device can be used to connect to a private Ethernet line.
 
Wireless interface
You can quickly create a wireless network at home or in the office, which will allow your employees or members of your family to connect to a wireless network almost anywhere (within range of a wireless network.) The router can operate as an access point for connecting wireless devices, which support 802.11b, 802.11g and 802.11n standards. The device supports several security standards (WEP, WPA/WPA2), MAC address filtering and the WPS function. In addition, the device is equipped with a button for switching Wi-Fi network off/on. If needed, for example, when you leave home, you can turn off the router's wireless network at the touch of a button, while the devices connected to the LAN ports on the router will stay online.
 
Security
The DSL-2640U wireless router includes a built-in firewall. Enhanced security functions minimize threats of hackers and prevent intrusions to your network and block access to unwanted websites for users of your local network.
 
Easy setup and update
You can configure the settings of the DSL-2640U wireless router via the user-friendly web-based interface (the interface is available in several languages). Now you can simply update the firmware: the router itself finds approved firmware on D-Link update server and notifies when ready to install it.
