he DSL-2740U Wireless N ADSL2 4-Port Wi-Fi Router is a versatile, high-performance router
for home and the small office. With integrated ADSL2/2 , supporting download speeds up to
24 Mbps, firewall protection, Quality of Service (QoS), 802.11n wireless LAN, and 4 Ethernet
switch ports, the Wireless N ADSL2 4-Port Wi-Fi Router provides all the functions that a home
or small office needs to establish a secure and high-speed link to the Internet.

Ultimate Wireless Connection
The DSL-2740U reaches wireless speeds that are up to 4 times faster than 802.11g1. Maximize
wireless performance by connecting it to computers equipped with wireless N interfaces and
stay connected from virtually anywhere at home and in the office. It can also be used with
802.11g and 802.11b wireless networks to enable significantly improved reception.

Secure Connection
The DSL-2740U’s security features prevent unauthorized access to the home and office network
from wireless devices or from the Internet. 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 supports priority queues to enable
a group of home or office users to experience the benefit of a smooth network connection
without worrying about traffic congestion. Additionally, it supports WPA/WPA2 and WEP for
flexible user access security and data encryption methods, while a built-in WPS button provides
an easy way to establish a secure wireless connection.

Compatibility Assurance
The Wireless N ADSL2 4-Port Wi-Fi Router is backward compatible with existing 802.11b
and 802.11g wireless equipment, ensuring compatibility with a wide range of wireless
devices, making your older devices still relevent. In addition, it includes four Ethernet ports for
connecting Ethernet-enabled PCs, print servers, and other devices, making the DSL-2740U the
logical choice for users wanting a versatile and fast Wi-Fi router.
