DSL-2640U/B1A/T3AEOL EOS
Wireless N150 ADSL2+ Modem Router
Description
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.
Security
The DSL-2640U wireless router 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.
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 an access point 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.
Configuration and management
You can configure and manage the settings of the DSL-2640U router via the user-friendly web-based interface (the interface is available in several languages).
