Power Adapter CD-ROM with Installation Wizard, User Manual, and Special Offers One twisted-pair telephone cable used for ADSL connection One straight-through Ethernet cable One Quick Installation Guide Note: Using a power supply with a different voltage rating than the one included with the DSL-2740B will cause damage and void the warranty for this product. System Requirements ADSL Internet service Computer with: 200MHz Processor 64MB Memory CD-ROM Drive Ethernet Adapter with TCP/IP Protocol Installed Windows XP/2000 Internet Explorer v6 or later, FireFox v1.5 D-Link Click'n Connect Utility Computer with Windows 2000/XP D-Link DSL-2740B User Manual 3 Section 1 - Product Overview 11 Introduction HIGH-SPEED ADSL2/2+ INTERNET CONNECTION Latest ADSL2/2+ standards provide Internet transmission of up to 24Mbps downstream, 1Mbps upstream. HIGH-PERFORMANCE WIRELESS Embedded 802.11n technology for high-speed wireless connection, complete compatibility with 802.11b/g wireless devices TOTAL SECURITY Firewall protection from Internet attacks, user access control, WPA/WPA2 wireless security. ULTIMATE INTERNET CONNECTION The DSL-2740B ADSL2+ router is a versatile, high-performance remote router for home and the small office. With integrated ADSL2/2+ supporting up to 24Mbps download speed, firewall protection, Quality of Service (QoS), 802.11n wireless LAN and 4 Ethernet switch ports, this router provides all the functions that a home or small office needs to establish a secure and high-speed remote link to the outside world. ULTIMATE WIRELESS CONNECTION WITH MAXIMUM SECURITY This router provides maximize wireless performance by connecting this router to computer interfaces and stay connected from virtually anywhere at home and in the office. The router can be used with 802.11b/g/n wireless networks to enable significantly improved reception. It supports WPA/WPA2 and WEP for flexible user access security and data encryption methods. FIREWALL PROTECTION & QoS Security features prevents unauthorized access to the home and office network, be it from the wireless devices or from the Internet. The router provides firewall security using Stateful Packet Inspection (SPI) and hacker attack logging for 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 and streaming multimedia over the Internet. *Maximum wireless signal rate derived from IEEE standard 802.11n specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate. Environmental factors will adversely affect wireless signal range. D-Link DSL-2740B User Manual 4 Section 1 - Product Overview Features Faster Wireless Networking - The DSL-2740B provides up to 270Mbps* wireless connection with other 802.11n wireless clients. This capability allows users to participate in real-time activities online, such as video streaming, online gaming, and real-time audio. Compatible with 802.11b and 802.11g Devices - The DSL-2740B is still fully compatible with the IEEE 802.11b and g standards, so it can connect with existing 802.11b and g PCI, USB and Cardbus adapters. DHCP Support - Dynamic Host Configuration Protocol automatically and dynamically assigns all LAN IP settings to each host on your network. This eliminates the need to reconfigure every host whenever changes in network topology occur. Network Address Translation (NAT) - For small office environments, the DSL-2740B allows multiple users on the LAN to access the Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user. NAT improves network security in effect by hiding the private network behind one global and visible IP address. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection. Precise ATM Traffic Shaping - Traffic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the Quality of Service for ATM data transfer. High Performance - Very high rates of data transfer are possible with the Router. Up to 24Mbps downstream bit rate using the G.dmt standard. (For ADSL2+) Full Network Management - The DSL-2740B incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based network management via Telnet connection. Easy Installation - The DSL-2740B uses a web-based graphical user interface program for convenient management access and easy set up. Any common web browser software can be used to manage the Router. *Maximum wireless signal rate derived from IEEE standard 802.11n specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate. Environmental factors will adversely affect wireless signal range.
