Dual-Band Wireless A+G Broadband Router
Chapter 1: Introduction
The Dual-Band Wireless A+G Broadband Router is like four devices in one
box! The Router function lets you securely share one high-speed Internet con-
nection among your entire network, while the 4-port full duplex 10/100 Switch
jump-starts your wired-Ethernet network. Connect four PCs directly, or daisy-
chain out to more hubs and switches to create as big a network as you need.

The Dual-Band Wireless A+G Broadband Router also contains two Wireless
Access Points, supporting all three wireless networking specifications. The
first Access Point uses the 2.4GHz radio band, supporting both the popular and
inexpensive Wireless-B (802.11b) standard at 11Mbps, and the new, almost
five times faster, Wireless-G (draft 802.11g) at 54Mbps. The second Access
Point radio operates in the 5GHz band, and supports Wireless-A (802.11a) net-
working, also at 54Mbps. Since the two radios operate in different bands, they
can work simultaneously, blanketing your wireless zone with bandwidth.

To protect your data and privacy, the Dual-Band Wireless A+G Broadband
Router can encrypt all wireless transmissions. The MAC Address filter lets
you decide exactly who has access to your wireless network. The Router also
serves as a DHCP Server, has NAT technology to protect against Internet
intruders, DMZ capability, supports VPN pass-through, and can be configured
to filter internal users' access to the Internet. Configuration is a snap with the
web browser-based configuration utility.
