Wireless Router Features

The Wireless Router incorporates many advanced features, carefully

designed to provide sophisticated functions while being easy to use.

In tern et Access

Features

◆ Shared Internet Access. All users on the LAN or WLAN can access

the Internet through the Wireless 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).

◆ DSL & Cable Modem Support. The Wireless Router has a

10/100Base-T Ethernet port for connecting a DSL or Cable

Modem. All popular DSL and Cable Modems are supported.

SingTel RAS and Big Pond (Australia) login support is also

included.

◆ PPPoE, PPTP, SingTel RAS, and Telstra Big Pond Support. The

Internet (WAN port) connection supports PPPoE (PPP over

Ethernet), PPTP (Peer-to-Peer Tunneling Protocol), SingTel RAS

and Telstra Big Pond (Australia), as well as “Direct Connection”

type services.

◆ Fixed or Dynamic IP Address. On the Internet (WAN port)

connection, the Wireless Router supports both Dynamic IP

Address (IP Address is allocated on connection) and Fixed IP

Address.

Advan ced

In tern et

Fun ction s

◆ Communication Applications. Support for Internet

communication applications, such as interactive Games,

Telephony, and Conferencing applications, which are often

difficult to use when behind a Firewall, is included.

◆ Special Internet Applications. Applications which use non-

standard connections 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.

◆ Virtual Servers. This feature allows Internet users to access

Internet servers on your LAN. The required setup is quick and easy.

◆ Multi-DMZ. For each WAN (Internet) IP address allocated to you,

one PC on your local LAN can be configured to allow unrestricted

2-way communication with Servers or individual users on the

Internet. This provides the ability to run programs which are

incompatible with Firewalls.

◆ URL Filter. Use the URL Filter to block access to undesirable Web

sites by LAN users.

Download from Www.Somanuals.com. All Manuals Search And Download.

Introduction

◆ Internet Access Log. See which Internet connections have been

made.

◆ Access Control. Using the Access Control feature, you can assign

LAN users to different groups, and determine which Internet

services are available to each group.

◆ 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 Router complies with the

IEEE802.11g (DSSS) specifications for Wireless LANs.

◆ Supports both 802.11b and 802.11g Wireless Stations. The

802.11g standard provides for backward compatibility with the

802.11b standard, so both 802.11b and 802.11g Wireless stations

can be used simultaneously.

◆ Speeds to 54 Mbps. All speeds up to the 802.11g maximum of 54

Mbps are supported.

◆ WEP support. Support for WEP (Wired Equivalent Privacy) is

included. Key sizes of 64-bit and 128-bit are supported.

◆ 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.

◆ Simple Configuration. If the default settings are unsuitable, they

can be changed quickly and easily.

LAN Features

◆ 4-Port Switching Hub. The Wireless Router incorporates a 4-port

10/100Base-T 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 Router can act as a DHCP Server for devices

on your local LAN and WLAN.

◆ Multi Segment LAN Support. LANs containing one or more

segments are supported, via the Wireless Router's RIP (Routing

Information Protocol) support and built-in static routing table.

AT-WA1004G User’s Guide

Con figuration

an d

◆ Easy Setup. Use your WEB browser from anywhere on the LAN or

WLAN for configuration.

Man agem en t

◆ Remote Management. The Wireless Router can be managed from

any PC on your LAN. And, if the Internet connection exists, it can

also (optionally) be configured via the Internet.

◆ UPnP Support. UPnP (Universal Plug and Play) allows automatic

discovery and configuration of the Wireless Router. UPnP is by

supported by Windows ME, XP, or later.

Security

Features

◆ Password - protected Configuration. Optional password

protection is provided to prevent unauthorized users from

modifying the configuration data and settings.

◆ Wireless LAN Security. WEP (Wired Equivalent Privacy) is

supported, as well as Wireless access control to prevent unknown

wireless stations from accessing your LAN.

◆ NAT Protection. An intrinsic side effect of NAT (Network Address

Translation) technology 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 Router.

◆ Stateful Inspection 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 bandwidth and so many

resources that Internet access becomes unavailable. The Wireless

Router incorporates protection against DoS attacks.

use different Channels with at least a 2 channel separation.

2. Connect LAN Cables using standard LAN cables to connect PCs to

the Switching Hub ports on the Wireless Router. Both 10Base-T and

100Base-T connections can be used simultaneously.

If required, connect any port to a normal port on another Hub, using

a standard LAN cable. Any LAN port on the Wireless Router will

automatically function as an “Uplink” port when required.

3. Connect the DSL or Cable modem to the WAN port on the Wireless

Router. Use the cable supplied with your DSL/Cable modem. If no

cable was supplied, use a standard cable.

◆ Netscape V4.08 or late

◆ Internet Explorer V4 or later

Preparation

Before attempting to configure the Wireless Router, please ensure that:

◆ Your PC can establish a physical connection to the Wireless

Router. The PC and the Wireless Router must be directly

connected (using the Hub ports on the Wireless Router) or on the

same LAN segment.

◆ The Wireless Router must be installed and powered ON.

◆ If the Wireless Router's default IP Address (192.168.1.1) is already

used byanotherdevice, the otherdevice must be turned OFFuntil

the Wireless Router is allocated a new IP Address during

configuration.

Usin g UPn P

If your Windows system supports UPnP, an icon for the Wireless Router

will appear in the system tray, notifying you that a new network device

has been found, and offering to create a new desktop shortcut to the

newly-discovered device.

◆ Unless you intend to change the IP Address ofthe Wireless Router,

you can accept the desktop shortcut.

◆ Whether you accept the desktop shortcut or not, you can always

find UPnP devices in My Network Places (previously called

Network Neighborhood).

◆ Double - click the icon for the Wireless Router (either on the

To establish a connection from your PC to the Wireless Router:

1. After installing the Wireless Router in your LAN, start your PC. If your

PC is already running, restart it.

2. Start your WEB browser.

3. In the Address box, enter “http://” and the IP Address of the Wireless

Router, as in this example, which uses the Wireless Router's default

IP Address: http://192.168.1.1.

If you cannot connect

If the Wireless Router does not respond, check the following:

The Wireless Router is properly installed, LAN connection is OK, and it is

powered ON. You can test the connection by using the “Ping”

command:

◆ Open the MS-DOS window or command prompt window.

◆ Enter the command: ping 192.168.1.1 If no response is received,

either the connection is not working, or your PC's IP address is

not compatible with the Wireless Router's IP Address. (See

below.)

◆ If your PC is using a fixed IP Address, its IPAddress must be within

the range 192.168.1.2 to 192.168.1.254 to be compatible with

the Wireless Router's default IP Address of 192.168.1.1. Also, the

Network Mask must be set to 255.255.255.0. R e f e r to C h apter 4,

A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP

address to a DHCP Client (PC or device) upon request.

◆ The client request is made when the client device starts up

(boots).

◆ The DHCP Server provides the Gateway and DNS addresses to the

client, as well as allocating an IP Address.

◆ The Wireless Router can act as a DHCP server.

◆ Windows 95/98/ME and other non-Server versions of Windows

will act as a DHCP client. This is the default Windows setting for

the TCP/IP network protocol. However, Windows uses the term

Obtain an IP Address automatically instead of “DHCP Client”.

◆ You must NOT have two or more DHCP Servers on the same LAN

segment. (If your LAN does not have other Routers, this means

there must only be one (1) DHCP Server on your LAN.)

Win dows Clien ts

This section describes how to configure Windows clients for Internet

access via the Wireless Router.

The first step is to check the PC's TCP/IP settings.

The Wireless Router uses the TCP/IP network protocol for all functions,

so it is essential that the TCP/IP protocol be installed and configured on

each PC.

TCP/ IP Settin gs If using the default Wireless Router settings, and the default Windows

TCP/IP settings, no changes need to be made.

Overview

◆ By default, the Wireless 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

required:

◆ The Gateway must be set to the IP address of the wireless router.

◆ The DNS should be set to the address provided by your ISP.

Note

If your LAN has a router, the LAN administrator must reconfigure the

router itself.

Operation

Once both the Wireless Router and the PCs are configured, operation is

automatic.

However, there are some situations where additional Internet

configuration may be required:

◆ If using Internet-based Communication Applications, it may be

necessary to specify which PC receives an incoming connection.

Ref e r to C h apter 6, A d vanced F e atures on page 81 for further

details.

◆ Applications which use non-standard connections or port

numbers may be blocked by the Wireless Router's built-in firewall.

You can define such applications as Special Applications to allow

them to function normally. R e f e r to C h apter 6, A d vanced F e atures

on page 81 for further details.

◆ Some non-standard applications may require use of the DMZ

f e ature. R e f e r to C h apter 6, A d vanced F e atures on page 81 for

Dyn am ic DNS (Dom ain Nam e Server)

This free service is very useful when combined with the Virtual Server

feature. It allows Internet users to connect to your Virtual Servers using a

URL, rather than an IP Address.

This also solves the problem of having a dynamic IP address. With a

dynamic IP address, your IP address may change whenever you connect,

which makes it difficult to connect to you.

The Service works as follows:

1. You must register for the service at http://www.dyndns.org

(Registration is free). Your password will be e-mailed to you.

2. After registration, use the “Create New Host” option (at

www.dyndns.org) to request your desired Domain name.

3. Enter your data from www.dyndns.org in the Wireless Router's

DDNS screen.

4. The Wireless Router will then automatically ensure that your current

IP Address is recorded at http://www.dyndns.org

5. From the Internet, users will be able to connect to your Virtual

Servers (or DMZ PC) using your Domain name, as shown on this

screen.

one PC can use each Special application at any time. Also, when

one PC is finished using a particular Special Application, there

may need to be a “Time-out” before another PC can use the same

Special Application. The “Time-out” period may be up to 3

minutes.

Note

If an application still cannot function correctly, try using the “DMZ”

feature.

Multi-DMZ This feature, if enabled, allows the DMZ computer or computers on your

LAN to be exposed to all users on the Internet.

◆ This allows almost any application to be used on the “DMZ PC”.

◆ The “DMZ PC” will receive all “Unknown” connections and data.

◆ If the DMZ feature is enabled, you must select the PC to be used

as the “DMZ PC”.

If you have multiple Internet IP addresses, you can assign one DMZ PC

for each Internet IP address.

If you only have one WAN IP address, only “DMZ 1” can be used, and only

one PC can be the DMZ PC. The current WAN IP address is displayed. If

this address is assigned upon connection, and no connection currently

exists, then this address will be blank or 0.0.0.0.

Virtual Servers

This feature, sometimes called Port Forwarding, allows you to make

Servers on your LAN accessible to Internet users. Normally, Internet users

would not be able to access a server on your LAN because:

◆ Your Server does not have a valid external IP Address.

◆ Attempts to connect to devices on your LAN are blocked by the

firewall in this device.

The “Virtual Server” feature solves these problems and allows Internet

users to connect to your servers, as illustrated below.

Figure 30 Virtual Servers

IP Address Seen

by In tern et

Users

Note that, in this illustration, both Internet users are connecting to the

same IP Address, but using different protocols.

To Internet users, all virtual Servers on your LAN have the same IP

Address. This IP Address is allocated by your ISP.

This address should be static, rather than dynamic, to make it easier for

Internet users to connect to your Servers.

However, you can use the DDNS (Dynamic DNS) feature to allow users to

connect to your Virtual Servers using a URL, instead of an IP Address.

Overview

◆ If you don't have other Routers or Gateways on your LAN, you can

ignore the “Routing” page completely.

◆ If the Wireless Router is only acting as a Gateway for the local LAN

segment, ignore the “Routing” page even if your LAN has other

Routers.

◆ If your LAN has a standard Router on your LAN, and the Wireless

Router is to act as a Gateway for all LAN segments, enable RIP

(Routing Information Protocol) and ignore the Static Routing

table.

◆ If your LAN has other Gateways and Routers, and you wish to

control which LAN segments use each Gateway, do NOT enable

RIP (Routing Information Protocol). Configure the Static Routing

table instead. (You also need to configure the other Routers.)

◆ If using Windows 2000 Data center Server as a software Router,

enable RIP on the Wireless Router, and ensure the following

Windows 2000 settings are correct:

— Open Routing and Remote Access.

— In the console tree, select Routing and Remote Access, [server

Local Router

The local router is the Router installed on the same LAN segment as the

Wireless Router. This router requires that the Default Route is the

Wireless Router itself. Typically, routers have a special entry for the

Default Route. It should be configured as follows:

Normally 0.0.0.0, but check your router

◆ For a router with a direct connection to the Wireless Router's local

Router, the Gateway IP Address is the address of the Wireless

Router's local router.

◆ For routers which must forward packets to another router before

reaching the Wireless Router's local router, the Gateway IP

Gen eral Problem s

Cannot connect to the Wireless Router to configure it.

Check the following:

◆ The Wireless Router is properly installed, LAN connections are OK,

and it is powered ON.

◆ Ensure that your PC and the Wireless Router are on the same

network segment. (If you don't have a router, this must be the

case.)

◆ If your PC is set to “Obtain an IP Address automatically” (DHCP

client), restart it.

◆ If your PC uses a Fixed (Static) IP address, ensure that it is using an

IP Address within the range 192.168.0.2 to 192.168.0.254 and thus

compatible with the Wireless Router's default IP Address of

192.168.1.1. Also, the Network Mask should be set to

255.255.255.0 to match the Wireless Router.

In Windows, you can check these settings by using Control Panel-

Network to check the Properties for the TCP/IP protocol.

Troubleshooting

In tern et Access

When I enter a URL or IP address I get a time out error.

A number of things could be causing this. Try the following

troubleshooting steps.

◆ Check if other PCs work. If they do, ensure that your PCs IP settings

are correct. If using a Fixed (Static) IP Address, check the Network

Mask, Default gateway and DNS as well as the IP Address.

◆ If the PCs are configured correctly, but still not working, check the

Wireless Router. Ensure that it is connected and ON. Connect to it

and check its settings. (If you can't connect to it, check the LAN

and power connections.)

◆ If the Wireless Router is configured correctly, check your Internet

connection (DSL/Cable modem etc) to see that it is working

correctly.

Some applications do not run properly when using the Wireless

Router.

The Wireless Router processes the data passing through it, so it is not

transparent.

Use the Special Applications feature to allow the use of Internet

applications which do not function correctly.

If this does solve the problem you can use the DMZ function. This should

work with almost every application, but:

◆ It is a security risk, since the firewall is disabled.

◆ Only one (1) PC can use this feature.

Wireless Access

My PC cannot locate the Wireless Access Point.

Check the following:

◆ Your PC is set to Infrastructure Mode. (Access Points are always in

Infrastructure Mode)

◆ The SSID on your PC and the Wireless Access Point are the same.

Remember that the SSID is case-sensitive. So, for example “Work-

group” does not match “workgroup”.

◆ Both your PC and the Wireless Router must have the same setting

for WEP. The default setting for the Wireless Router is disabled, so

your wireless station should also have WEP disabled.

◆ If WEP is enabled on the Wireless Router, your PC must have WEP

enabled, and the key must match.

◆ If the Wireless Router's Wireless screen is set to Allow LAN access

to selected Wireless Stations only, then each of your Wireless

stations must have been selected, or access will be blocked.

◆ To see if radio interference is causing a problem, see if connection

is possible when close to the Wireless Router. Remember that the

connection range can be as little as 100 feet in poor

environments.

Wireless connection speed is very slow.

The wireless system will connect at the highest possible speed,

depending on the distance and the environment. To obtain the highest

possible connection speed, you can experiment with the following:

◆ Wireless Router location.

Try adjusting the location and orientation of the Wireless Router.

◆ Wireless Channel

If interference is the problem, changing to another channel may

show a marked improvement.

◆ Radio Interference

Other devices may be causing interference. You can experiment

by switching other devices OFF, and see if this helps. Any “noisy”

devices should be shielded or relocated.

◆ RF Shielding

Your environment may tend to block transmission between the

wireless stations. This will mean high access speed is only possible

when close to the Wireless Router.

About Wireless LANs

Modes

Wireless LANs can work in either of two (2) modes:

◆ Ad-hoc

◆ Infrastructure

Ad-h oc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet)

LAN. Wireless Stations (for example, notebook PCs with wireless cards)

communicate directly with each other.

In frastructure In Infrastructure Mode, one or more Access Points are used to connect

Wireless Stations (for example, Notebook PCs with wireless cards) to a

wired (Ethernet) LAN. The Wireless Stations can then access all LAN

resources.

Mode

Note

Access Points can only function in “Infrastructure” mode, and can

communicate only with Wireless Stations which are set to

“Infrastructure” mode.

BSS/ ESS

BSS A group of Wireless Stations and a single Access Point, all using the same

ID (SSID), form a Basic Service Set (BSS).

Using the same SSID is essential. Devices with different SSIDs are unable

to communicate with each other.

ESS A group of Wireless Stations, and multiple Access Points, all using the

same ID (ESSID), form an Extended Service Set (ESS).

Different Access Points within an ESS can use different Channels. In fact,

to reduce interference, it is recommended that adjacent Access Points

SHOULD use different channels.

As Wireless Stations are physically moved through the area covered by

an ESS, they will automatically change to the Access Point which has the

least interference or best performance. This capability is called Roaming.

(Access Points do not have or require Roaming capabilities.)

About Wireless LANs

Ch an n els

The Wireless Channel sets the radio frequency used for communication.

◆ Access Points use a fixed Channel. You can select the Channel

used. This allows you to choose a Channel which provides the

least interference and best performance. In the USA and Canada,

11 channelare available. Ifusing multiple Access Points, it is better

if adjacent Access Points use different Channels to reduce

interference.

◆ In “Infrastructure” mode, Wireless Stations normally scan all

Channels, looking for an Access Point. If more than one Access

Point can be used, the one with the strongest signal is used. (This

can only happen within an ESS.)

◆ If using “Ad-hoc” mode (no Access Point), all Wireless stations

should be set to use the same Channel. However, most Wireless

stations will still scan all Channels to see if there is an existing “Ad-

hoc” group they can join.

WEP

WEP (Wired Equivalent Privacy) is a standard for encrypting data before

it is transmitted.

This is desirable because it is impossible to prevent snoopers from

receiving any data which is transmitted by your Wireless Stations. But if

the data is encrypted, then it is meaningless unless the receiver can

decrypt it.

If WEP is used, the Wireless Stations and the Access Point must have

the same settings for each of the following:

WEP

Key

Off, 64-bit, 128-bit.

For 64-bit encryption, the Key value must match.

For 128-bit encryption, the Key value must match.

WEP

Open System or Shared Key.

About Wireless LANs

Wireless LAN Con figuration

To allow Wireless Stations to use the Access Point, the Wireless Stations

and the Access Point must use the same settings, as follows:

On client Wireless Stations, the mode must be set to

“Infrastructure”. (The Access Point is always in

“Infrastructure” mode.)

Mode

Wireless Stations should use the same SSID (ESSID)

as the Access Point they wish to connect to.

Alternatively, the SSID can be set to “any” or null

(blank) to allow connection to any Access Point.

SSID (ESSID)

The Wireless Stations and the Access Point must use

the same settings for WEP (OFF, 64-bit, 128-bit).

WEP Key: If WEP is enabled, the Key must be the

same on the Wireless Stations and the Access Point.

WEP

WEP Authentication: If WEP is enabled, all Wireless

Stations must use the same setting as the Access

Point (either “Open System” or “Shared Key”).
