Chapter 1 Introduction
1.1 Product Overvie w
Thank you for choosing the TD-W8151N 150M bps Wireless N ADSL2+ Modem Router. T h e
device is designed to provide a simple and cost-effective ADSL Internet connection for a private
Ethernet or I E E E 802.11n/ I EE E 802.11g/ I E EE 802.11b wireless network.
The TD-W8151N 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 networ ked and connected to the Internet using a single Wide Area Network
(WAN) interface and single global IP address. The advanced security enhancements, IP/M AC Filter, Application Filter and URL Filter can help to protect your network from potentially
devastati ng intrusions by m ali cious agents from the outside of your network.
Quick Start of the Web-based Utility is supplied and friendly help messages ar e provided for the
configuration. Network and Router management is done through the Web-based Utility which can
be accessed through local E thernet usi ng any w eb brows er.
ADSL
The TD-W8151N supports full-rate ADSL2+ connectivity conforming to the ITU and ANSI

dual latenc y ADSL2+ framing (fast and interleaved) and the I.432 ATM Physical Layer.
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-bit WEP encryption security,
WPA-PSK/WPA2-PS K authentic ation, as well as TKI P /AE S encryption s ecurity.
