Affordable High-Speed Connection for Home & Small Office

Ready Wired & Wireless LAN Connection
The DSL-2640B provides an integrated 802.11g WLAN interface supporting wireless speeds of up to 54Mbps and interoperability with 802.11b wireless devices on the 2.4GHz frequency band. These built-in functions save you the cost and trouble of installing a seperate wireless Access Point and an Ethernet switch.
Firewall Protection & QoS
Security features prevents unauthorized access to the home and office network from internet intruders. The router provides firewall security using Stateful Packet Inspection (SPI) and Denial of Service (DoS) attack prevention. SPI inspects the contents of all incoming packet headers before deciding what packets are allowed to pass through. Router access control is provided with packet filtering based on port and source/destination MAC/IP addresses. For Quality of Service (QoS), the router supports multiple priority queues to enable a group of home or office users to experience the benefit of a smooth network connection of inbound and outbound data without concern of traffic congestion. This QoS allows users to enjoy high ADSL transmission for bandwidth-hungry applications like VoIP, streaming multimedia and online gaming over the internet.
