HIGH-SPEED INTERNET

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.

FIREWALL PROTECTION & QoS

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.

The wireless router portion supports 802.11n speeds up to 300 mbps and is backwards compatible with older WiFi specifications as well. The router is IPv6 ready and has a number of security and speed enhancements over older products in the line. The router has WPA/WPA2 and WEP data encryption. It also has four fast Ethernet ports to connect to local computers.

The router also has TR-069 management support and is compatible with any ISP according to D-Link. Other security features include SPI, a hacker attack log that inspect packets before they come in, and protection against DoS attacks. The new modem is available right now for $79.99 online and in stores.

WISH is short for Wireless Intelligent Stream Handling, a technology developed to enhance your experience of using a wireless network by prioritizing the traffic of different applications.

Enable WISH:

Enable this option if you want to allow WISH to prioritize your traffic.

HTTP:

Allows the router to recognize HTTP transfers for many common audio and video streams and prioritize them above other traffic. Such streams are frequently used by digital media players.

Windows Media Center:

Enables the router to recognize certain audio and video streams generated by a Windows Media Center PC and to prioritize these above other traffic. Such streams are used by systems known as Windows Media Extenders, such as the Xbox 360.

Automatic:

When enabled, this option causes the router to automatically attempt to prioritize traffic streams that it doesn’t otherwise recognize, based on the behaviour that the streams exhibit. This acts to deprioritize streams that exhibit bulk transfer characteristics, such as file transfers, while leaving interactive traffic, such as gaming or VoIP, running at a normal priority.

WISH Rules:

A WISH Rule identifies a specific message flow and assigns a priority to that flow. For most applications, the priority classifiers ensure the right priorities and specific WISH Rules are not required.

WISH supports overlaps between rules. If more than one rule matches for a specific message flow, the rule with the highest priority will be used.

Name:

Create a name for the rule that is meaningful to you.

Priority:

The priority of the message flow is entered here. The four priorities are defined as:

BK: Background (least urgent)
BE: Best Effort.
VI: Video
VO: Voice (most urgent)

Protocol:

The protocol used by the messages.

Host IP Range:

The rule applies to a flow of messages for which one computer’s IP address falls within the range set here.

Host Port Range:The rule applies to a flow of messages for which host’s port number is within the range set here.
