Introduction
Congratulations on the purchase of your new TEW-635BRM. The 300Mbps Wireless N
ADSL 2/2+ Modem Router is a multi-function device providing the following services:
•ADSL Modem.
•Shared Broadband Internet Access for all LAN users.
•Wireless Access Point for 802.11b, 802.11g and 802.11n Wireless Stations.
•4-Port Switching Hub for 10BaseT or 100BaseT connections.
Features
The 300Mbps Wireless N ADSL 2/2+ Modem Router incorporates many advanced features,
carefully designed to provide sophisticated functions while being easy to use.
Internet Access Features
•Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the Wireless ADSL Router, using only a single external IP Address. The local
(invalid) IP Addresses are hidden from external sources. This process is called NAT
(Network Address Translation).
•Built-in ADSL Modem. The Wireless ADSL Router has a built-in ADSL modem,
supporting all common ADSL connections.
•IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless ADSL Router
supports all common connection methods.
•Auto-detection of Internet Connection Method. In most situations, the Wireless
ADSL Router can test your ADSL and Internet connection to determine the connection
method used by your ISP.
•Fixed or Dynamic IP Address. On the Internet (ADSL port) connection, the Wireless
ADSL Router supports both Dynamic IP Address (IP Address is allocated on connection)
and Fixed IP Address.

2
Advanced Internet Functions
•Application Level Gateways (ALGs). Applications which use non-standard connec-
tions or port numbers are normally blocked by the Firewall. The ability to define and
allow such applications is provided, to enable such applications to be used normally.
•Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows
users to connect to Servers on your LAN using a Domain Name, even if you have a dy-
namic IP address which changes every time you connect.
•URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
•Access Control. Using the Access Control feature, you can assign LAN users to differ-
ent groups, and determine which Internet services are available to each group.
•Firewall. As well as the built-in firewall to protect your LAN, you can define Firewall
Rules to determine which incoming and outgoing traffic should be permitted.
•Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate only at
certain times. This provides great flexibility in controlling Internet -bound traffic.
•Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog
Server. Log data can also be E-mailed to you.
•Port Triggering. This feature, also called Special Applications, allows you to use
Internet applications which normally do not function when used behind a firewall.
•Port Forwarding. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
•QoS Support Quality of Service can be used to handle packets so that more important
connections receive priority over less important one.
•VPN Pass through Support. PCs with VPN (Virtual Private Networking) software
using PPTP, L2TP and IPSec are transparently supported - no configuration is required.
Wireless Features
•Standards Compliant. The Wireless ADSL Router complies with the IEEE802.11g
(DSSS) specifications for Wireless LANs.
•Supports 11n Wireless Stations. The 802.11n Draft standard provides for backward
compatibility with the 802.11b standard, so 802.11n, 802.11b and 802.11g Wireless sta-
tions can be used simultaneously.
•WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of
64 Bit and 128 Bit are supported. WEP encrypts any data before transmission, providing
protection against snoopers.
•WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission,
providing protection against snoopers. The WPA-PSK is a later standard than WEP, and
provides both easier configuration and greater security than WEP.
•WPA2-PSK support. Support for WPA2 is also included. WPA2 uses the extremely
secure AES encryption method.
•802.1x Support. Support for 802.1x mode is included, providing for the industrial-
strength wireless security of 802.1x authentication and authorization.
•Wireless MAC Access Control. The Wireless Access Control feature can check the
MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless
Stations can access your LAN.
•WPS Support. WPS (Wi-Fi Protected Setup) can simplify the process of connecting any
device to the wireless network by using the push button configuration (PBC) on the Wire-
less Access Point, or entering PIN code if there's no button.
•WDS Support. Support for WDS (Wireless Distribution System) allows the Wireless
Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point Bridge
modes are supported.

•Simple Configuration. If the default settings are unsuitable, they can be changed
quickly and easily.
LAN Features
•4-Port Switching Hub. The Wireless ADSL Router incorporates a 4-port 10/100BaseT
switching hub, making it easy to create or extend your LAN.
•DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The Wireless ADSL Router can act as a
DHCP Server for devices on your local LAN and WLAN.
Configuration & Management
•Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configu-
ration.
•Configuration File Upload/Download. Save (download) the configuration data from
the Wireless ADSL Router to your PC, and restore (upload) a previously-saved configura-
tion file to the Wireless ADSL Router.
•Remote Management. The Wireless ADSL Router can be managed from any PC on
your LAN or Wireless LAN. And, if the Internet connection exists, it can also (optionally)
be configured via the Internet.
•Network Diagnostics. You can use the Wireless ADSL Router to perform a Ping or
DNS lookup.
Security Features
•Password - protected Configuration. Password protection is provided to prevent
unauthorized users from modifying the configuration data and settings.
•Wireless LAN Security. WPA-PSK, WEP and Wireless access control by MAC ad-
dress are all supported. The MAC-level access control feature can be used to prevent
unknown wireless stations from accessing your LAN.
•NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech-
nology is that by allowing all LAN users to share a single IP address, the location and
even the existence of each PC is hidden. From the external viewpoint, there is no network,
only a single device - the Wireless ADSL Router.
•Firewall. All incoming data packets are monitored and all incoming server requests are
filtered, thus protecting your network from malicious attacks from external sources.
•Protection against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much band-
width and so many resources that Internet access becomes unavailable. The Wireless
ADSL Router incorporates protection against DoS attacks.

Wireless Performance Considerations
There are a number of factors that can impact the range of wireless devices.
1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at
an angle. The more material the signal has to pass through the more signal you will lose.
2. Keep the number of obstructions to a minimum. Each obstruction can reduce the range of
a wireless device. Position the wireless devices in a manner that will minimize the amount
of obstructions between them.
3. Building materials can have a large impact on your wireless signal. In an indoor environ-
ment, try to position the wireless devices so that the signal passes through less dense
material such as dry wall. Dense materials like metal, solid wood, glass or even furniture
may block or degrade the signal.
4. Antenna orientation can also have a large impact on your wireless signal. Use the wireless
adapter’s site survey tool to determine the best antenna orientation for your wireless de-
vices.
5. Interference from devices that produce RF (radio frequency) noise can also impact your
signal. Position your wireless devices away from anything that generates RF noise, such as
microwaves, radios and baby monitors.
6. Any device operating on the 2.4GHz frequency will cause interference. Devices such as
2.4GHz cordless phones or other wireless remotes operating on the 2.4GHz frequency can
potentially drop the wireless signal. Although the phone may not be in use, the base can
still transmit wireless signal. Move the phone’s base station as far away as possible from
your wireless devices.
If you are still experiencing low or no signal consider repositioning the wireless devices or
installing additional access points. The use of higher gain antennas may also provide the
necessary coverage depending on the environment.

PC Configuration
Overview
For each PC, the following may need to be configured:
•TCP/IP network settings
•Internet Access configuration
•Wireless configuration
Windows Clients
This section describes how to configure Windows clients for Internet access via the Wireless
ADSL Router.
The first step is to check the PC's TCP/IP settings.
The Wireless ADSL Router uses the TCP/IP network protocol for all functions, so it is essen-
tial that the TCP/IP protocol be installed and configured on each PC.
TCP/IP Settings - Overview
If using the default Wireless ADSL Router settings, and the default Win-
dows TCP/IP settings, no changes need to be made.
•By default, the Wireless ADSL Router will act as a DHCP Server, automatically providing
a suitable IP Address (and related information) to each PC when the PC boots.
•For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP
client.
If using a Fixed (specified) IP address, the following changes are re-
quired:
•The Gateway must be set to the IP address of the Wireless ADSL Router
•The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must re-
configure the Router itself. Refer to Chapter 8 - Ad-
vanced Setup for details.
