DSL-2640U/RB
Wireless N150 ADSL2+ (Annex B) Router with Ethernet WAN Support
Apraksts
ADSL Port and 4-port Switch
The router is equipped with an ADSL port to connect to an ADSL line. The built-in 4-port switch enables you to connect Ethernet-enabled computers, 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 are able to quickly create a wireless network at home or in your office, which lets your relatives or employees connect to your wireless network 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.
The router supports multiple functions for the wireless interface: several security standards (WEP, WPA/WPA2), MAC address filtering, and the WPS function.
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.
Security
The wireless router DSL-2640U 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.
Built-in Yandex.DNS service protects against malicious and fraudulent web sites and helps to block access to adult content on children's devices.
Easy configuration and update
You can configure the settings of the wireless router DSL-2640U via the user-friendly web-based interface (the interface is available in two languages – in Russian and in English).
The fast and easy configuration wizard allows you to specify all needed parameters in several simple steps.
You can simply update the firmware: the router itself finds approved firmware on D-Link update server and notifies when ready to install it.
