2.4GHz Wireless Broadband Router

DI-724P

Wireless Cable/DSL Router

With 802.11g Wireless LAN, 4-Port Switch & Parallel Print Server

The DI-724P is a versatile router that combines wireless broadband Internet sharing with robust firewall security, print server and
built-in 4-port switch for ready printer and workstation connection. Designed for home and office use, this router provides both
performance and advanced network functions, including high-speed wireless LAN connection, Internet protection and policy-based
content filtering.

Simplified, Cost-saving Broadband Internet
Connection

The DI-724P provides users with easy and cost-saving access to
the broadband Internet through a DSL or cable modem without
the need for wiring. To let everybody logon, this device
automatically creates and assigns an IP number for each user,
simplifying every one's logon operation.

High Wireless Speeds

At up to 54Mbps, this router provides wireless LAN users a very
high data transfer rate. Real wireless LAN throughput is about 8
times faster than that of 802.11b devices. In addition, adoption
of the 2.4GHz frequency, now available for public use in most
countries, makes this router an ideal solution for bandwidth
intensive WLAN applications.

Compatible With 802.11b and 802.11b+

In addition to providing 54Mbps rate when operating with
wireless users using D-Link AirPlusXtremeG+ equipment, this
router is also compatible with existing 802.11b and 802.11b+
wireless devices. This means that you may sacrifice some of the
router's high speed when you mix with your existing 802.11b
and 802.11b+ devices, but you will not lose any ability to
communicate.

Key Features

54Mbps high-speed wireless broadband Internet access *
10/100BASE-TX port for DSL/cable modem connection
WAN port supports PPPoE for DSL dial-up mode to save ISP
connection fee
Built-in 802.11g wireless LAN with real throughput 8 times
faster than 802.11b devices **
WLAN supports Dynamic Channel Selection (auto-selection of
least utilized channel of operation)
4 built-in 10/100BASE-TX switch ports with auto MDI/MDIX
support
Built-in parallel printer port/print server supporting Windows,
MacOS, Linux
Multi-sessions with VPN pass-through

Integrated Fast Ethernet Switch & Print Server

An integrated 4-port switch with auto MDI/MDIX support
provides plug-and-play connection to 4 computers. In
addition, a parallel print server port allows you to share a
parallel printer among your users.

Built-in Firewall & Access Security

To prevent unwanted Internet intruders from accessing your
private network, this router provides a feature-rich firewall
and access security. Filters can be set based on MAC
address, IP address, URL and/or domain name. Additional
advanced features include pass-through of multiple
concurrent IPSec and PPTP VPN sessions for
telecommuters or for anyone who needs to transmit
sensitive information securely.

Easy Setup

A simple yet intelligent, web-based setup wizard allows you
to quickly set up the router for secure computer connection
to share high-speed Internet connection, files, resources,
games, or just to communicate.
