1Introduction
1.1 Overview
Thank you for choosing this Wireless Broadband Router. This
Wireless Broadband Router is a multi-function device featuring a
wireless 54Mbps Access Point, a 4-port LAN switch and a WAN port,
which extends the existing broadband Cable/ADSL connection. It
allows the Internet connection to be shared through either the
54Mbps Access Point feature or the 10/100Base-TX Ethernet switch,
which also eliminates the purchase of additional hub or switch. Now
the wired and wireless networks are integrated to allow various
applications to access the Internet.
With the support of the newly emerged 802.11g standard, the
Access Point provides data transfer of up to 54 Mbps, up to 5 times
faster than 802.11b.Since 802.11g operates on the same frequency
of 2.4 GHz as 802.11b, it is backwards compatible with existing Wi-
Fi 802.11b devices. The benefit is that you can preserve the existing
802.11b infrastructure while migrating to the new 802.11g
infrastructure.
The router has a DHCP server that automatically assigns IP
addresses to your LAN or WLAN devices. With the built-in Network
Address Translation (NAT) function, your LAN/WLAN can access
the Internet through a single external IP address and at the same
time protected from outside intruders. The router can also be
configured to filter internal access to the Internet. It is designed to
provide a reliable Internet access solution for the corporate
environment as well as for the small office home office (SOHO).
