Ultimate Internet connection

The DSL-2640R wireless ADSL router is an affordable high performance ADSL router fit for homes and small offices. With integrated ADSL2/2+ supporting up to 24Mbps download speed, 802.11g wireless LAN, firewall protection, Quality of Service (QoS) and 4-port switch, this router provides all the essentials that a home or small office needs to establish a secure and high-speed remote link to the outside world.

Affordable high-speed connection for homes & small offices

Designed as a very affordable high performance ADSL router for home and SOHO users, the DSL-2640R provides not only low-cost, high-speed Internet connection, but also the security and Quality of Service (QoS) required by users in today’s high risk and versatile Internet environments.

Ready wired & wireless LAN connection

The DSL-2640R 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. It also provides four 10/100Mbps Ethernet switch ports for ready workstations connection. These built-in functions save you the cost and trouble of installing a separate wireless access point and an Ethernet switch.

Firewall protection & QoS

Security features prevent 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 protection. 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 smooth network connection of inbound and outbound data without concern of traffic congestion. This QoS support allows users to enjoy high ADSL transmission for applications such as VoIP, streaming multimedia and online games over the Internet.
