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).
