N300 Performance

The D-Link ADSL2+ Modem with Wireless N300 Router (DSL-2740B) is a versatile, high-performance router for your home or small office. With integrated ADSL2/2+ supporting up to 24Mbps download speed1, firewall protection, Quality of Service (QoS), 802.11n wireless connectivity 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

The ADSL2+ Modem with Wireless N300 Router provides wireless speeds that are superior to 802.11g2. Maximize wireless performance and stay connected from virtually anywhere at home or in the office. The DSL-2740B supports WPA™/WPA2™ and WEP data encryption methods for flexible user access security.

Safe and Secure

Security features prevent unauthorized access to the home and office network from wireless devices or from the Internet. The ADSL2+ Modem with Wireless N300 Router provides firewall security, such as Stateful Packet Inspection (SPI) and hacker attack logging. SPI inspects the contents of incoming packets before they are allowed in, while hacker logging helps to protect your network against Denial of Service (DoS) attacks. For Quality of Service (QoS), the router prioritizes traffic to enable a group of home or office users to enjoy the benefit of a smooth network connection without concern of traffic congestion.

Compatibility Assurance

The ADSL2+ Modem with Wireless N300 Router is backward compatible with existing 802.11b and 802.11g wireless equipment, ensuring compatibility with a wide range of wireless devices. In addition, this router includes four Ethernet ports ready for you to connect Ethernet-enabled PCs, print servers and other devices.
