Product Description:
The DSL-2640T wireless ADSL router is a
versatile, high-speed remote router for home and the small office. With
integrated ADSL2/2+ supporting up to 24Mbps download speed, firewall
protection, Quality of Service (QoS), 802.11g 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.
High-Speed ADSL Connection.
The DSL-2640T features the latest
ADSL2/ADSL2+ standards, providing speeds of up to 24Mbps downstream and
1Mbps upstream (ADSL2+), or 12Mbps downstream and 1Mbps upstream
(ADSL2). This router auto-senses the connection type and
auto-negotiates the best modulation scheme, using the G.hs (handshake)
protocol.
Ready Wireless LAN & Ethernet Connection for Workgroup.
The
DSL-2640T provides an integrated 802.11g WLAN interface supporting
wireless speeds of up to 54Mbps and interoperability with 802.11b
wireless devices on the 2.4GHz frequency band. It also provides four
10/100Mbps Ethernet switch ports for ready workstations connection.
These built-in functions save you the cost and trouble of installing a
separate wireless access point and an Ethernet switch.
Firewall Protection.
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. Access control is provided with packet filtering based on
port and source/destination MAC/IP addresses. With Virtual Server
Mapping, the router can be set to allow separate FTP, Web, and multiple
games to share the same Internet-visible IP address while still
protecting your servers and workstations from hackers. You can
configure any of the built-in LAN ports of the router to function as a
DMZ port. VPN pass-through is provided to let mobile users access files
and mail from offices to work at home without having to use complex VPN
client software.
Quality of Service Features.
The DSL-2640T supports 4 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 you to
enjoy high ADSL transmission for applications such as VoIP, multimedia
and on-line games over the Inter

Description
3-IN-1 DEVICE
The D-Link ADSL2/2+ Modem with Wireless Router (DSL-2640B) is a 3-in-1
device that combines the function of a high-speed DSL modem, wireless G
access point, and 4-port Ethernet router. The DSL-2640B supports the
latest ADSL2/2+ standards to provide higher performance (up to 24Mbps*
downstream and 3.5Mbps* upstream) and longer reach from your Internet
Service Provider’s (ISP) Digital Subscriber Line Access Multiplexer
(DSLAM).
ACCESS HIGH-SPEED INTERNET
Unlike a dial-up
Internet service, a DSL Internet connection is always on so that you do
not have to wait to access the Web. Setting up the DSL-2640B is simple
since it automatically detects your DSL settings to quickly establish a
connection to the Internet. With support for TR-067, compatibility with
your Internet Service Provider’s (ISP) infrastructure is ensured. This
device also supports TR-069, which automatically updates the firmware
and other settings when they become available from your ISP.
CONNECT NETWORKING DEVICES – WIRED OR WIRELESS
With the DSL-2640B, you can create a wireless network to connect
802.11g/802.11b devices as well as a wired network to connect up to
four 10/100 Ethernet devices. Share your high-speed DSL Internet
connection, photos, music, videos, printers, and Network Attached
Storage (NAS) with multiple users. The DSL-2640B includes a built-in
QoS engine that helps prioritize Internet traffic to enable smooth
Internet phone calls (VoIP) and lag-free online gaming. In addition,
this device includes Dual Active Firewalls (SPI and NAT) to help
protect your network from potential attacks from across the Internet.
To prevent unauthorized wireless access into your network, the
DSL-2640B supports the latest encryption including WEP, WPA™, and WPA2™.
Whether
it is for a home user who wants to share high-speed Internet access or
for a small office that needs Internet access for conducting essential
business activities, the ADSL2/2+ Modem with Wireless Router
(DLS-2640B) is the ideal all-in-one broadband and wireless networking
solution.
WHAT THIS PRODUCT DOES
