Chapter 1. Product Overview
1.1 Overview of the Router
Thank you for choosing the TD-W8920G 108M Wireless ADSL2+ Router. The Router is
designed to provide a simple and cost-effective ADSL Internet connection for a private Ethernet or
802.11g, 802.11b wireless network.
The Router is easy to use. The TD-W8920G connects to an Ethernet LAN or computers via
standard Ethernet ports. The ADSL connection is made using ordinary telephone line with
standard connectors. Multiple workstations can be networked and connected to the Internet using
a single Wide Area Network (WAN) interface and single global IP address. The advanced security
enhancements, IP Filtering and MAC Filtering can help protect your network from potentially
devastating intrusions by malicious agents from the outside of your network. Parental Control
provides flexible access control so that parents or network administrators can establish restricted
access policies for children or staff.
The Router is easy to install and manage. Quick Setup of the Web-based Utility is supplied and
friendly help messages are provided for every step. Network and Router management is done
through the Web-based Utility which can be accessed through local Ethernet using any web
browser. Remote management is provided so that you may configure the Router through WAN
port by the use of any Web browser.
ADSL
The TD- W8920G 108M Wireless ADSL2+ Router utilizes integrated ADSL2+ transceiver and
high speed MIPS CPU. The Router supports full-rate ADSL2+ connectivity conforming to the ITU
and ANSI specifications.
In addition to the basic DMT physical layer functions, the ADSL2+ PHY supports dual latency
ADSL2+ framing (fast and interleaved) and the I.432 ATM Physical Layer.
The TD- W8920G 108M Wireless ADSL2+ Router is a complete plug-and-play solution. The
Router integrates 4-port switch, firewall and NAT-Router. Its design is dedicated to Small
Office/Home Office (SOHO) wireless network solutions.
Wireless
In the most attentive wireless security, the Router provides multiple protection measures. It can be
set to turn off the wireless network name (SSID) broadcast so that only stations that have the
SSID can be connected. The Router provides wireless LAN 64/128/152-bit WEP encryption
security, WPA/WPA2 and WPA-PSK/WPA2-PSK authentication, as well as TKIP/AES encryption
security.
The router adopts 2x to 3x eXtended Range™WLAN transmission technology so that
transmission distance is 2-3 times of traditional IEEE 802.11g/b solutions. It is compatible with all
IEEE 802.11g and IEEE 802.11b products. In addition, it also adopts 108M Super G™WLAN
Transmission Technology, which offers the highest throughput performance available on the

market today, and data rates of up to 108Mbps. In dynamic 108M mode, the router can attach
IEEE 802.11b, 802.11g and 108Mbps Super G™devices at the same time in an integrated
environment.
