Overview of the 802.11g Router

The 802.11g Router is a small desktop router that sits between your local
Ethernet network and a remote network (e.g., the Internet). The 802.11g
Router contains an WAN port connecting to an external ADSL/Cable
modem, a DMZ port, a four-port 10/100Mbps Ethernet switch for
connection to PCs on your local wired net wor k, and a wireless interface fo r
connection to your local wireless network (supporting a data rate of up to
54 Mbps).

Data comes into the 802.11g Router from the local wired and wireless
LAN and then is “ro uted” t o the Int ernet , and vice ver sa.

802.11g Router Applications

ACCESSING THE INTERNET

The most common use of the 802.11g Router is to provide shared Internet access to allow everyone
on your LAN to surf the web and send/receive emails or files. The 802.11g Router can automatically
acquire a public IP address when connecting to the Internet. In turn, it will automatically assign IP
addresses to PCs (requesting DHCP client devices) on your LAN - you don’t have to apply for and
assign IP addresses to PCs o n your net wor k.

ACCESSING SERVERS FROM THE PUBLIC NETWORK

If you want special ser vers t o be accessi ble to r emot e users ac ross th e Inter net ( e.g., an e- mail s erver , an
FTP server, or a web ser ver ) , you ca n co nf ig ure th e 80 2 .11g Rout er to pro xy the service using its (public)
IP address. It means a remote user can access the server by using the 802.11g Router’s IP address.
Upon receiving a r equ e st, t h e 802.1 1 g Rou t er wil l r e- dir ect th e r eq ue st t o th e ac tu a l ser ver o n yo ur l ocal
network.

OPERATING AS AN ACCESS POINT

Additionally, the Wireless Router can also be configured as an Access Point, and acts as the central
point of your local wir eless networ k suppo rting a d ata r ate of up to 54 Mbp s. It all ows client device s on
your wireless network to access the Internet, to communicate with other wireless devices on your
wireless network, or to com municate with d evices o n your wired LAN n etwork.

Since 802.11g is based on the same 2.4GHz radio band as the 802.11b technology, the 802.11g Router
can inter-operate with existing 11Mbps 802.11b devices. Therefore you can protect your existing
investment in 802. 11b cl ient cards, an d migrat e to th e high- speed 802.1 1g stan dar d as your ne eds gr ow.

802.11g Router User’s Guide

High Level Configuration Steps Required for the 802.11g Router

This section describes configuration required for the 802.11g Router before it can work properly in
your network.

Normally, devices on both LANs (except for the Web servers) are configured to obtain their IP
addresses automat ica lly. De pendin g on wheth er ther e is a s epar ate DHC P server a vail able in your LAN
environment network, thus to determine if you need to enable the built-in DHCP server in the
Wireless Router. The following configuration step assumes that the route r’s built-in DHCPS will be
used.

Additionally, sin ce you need t o perfor m variou s configu ration chan ges to t he 802.11g Rout er, in cludi ng
the SSID, Channel number, the WEP key, …, etc., it is necessary to associate a fixed IP address with
the 802.11g Router, which is why the 802.11g Router will be shipped with a factory default private IP
address of 192.168. 1.1 (and a networ k ma sk of 255.25 5.2 55.0).

802.11g Router User’s Guide

Setting up a Windows PC or wireless client as DHCP clients

The following will give detailed steps of how to configure a PC or a wireless client to “obtain IP
addresses automatically”. For other types of configuration, please refer to the corresponding user
manual.

For the case of using a LAN attached PC, the PC must have an Ethernet interface installed properly,
be connected to the 802.11g Router either directly or through an external LAN switch, and have
TCP/IP installed and configured to obtain an IP address automatically from a DHCP server in the
network.

For the case of using a wireless client, the client must also have a wireless interface installed properly,
be physically within the radio range of the 802.11g Router, and have TCP/IP installed and configured
to obtain an IP addr ess aut oma tica lly fro m a DHCP serv er in the n etwork.

Configuring a PC running MS-Windows 95/98/Me:

1. Click the Start Butt on, and select Set tings .

2. Click the Control Panel. The Win95/98/Me Control Panel will appear.

3. Open the Net work s et up w i ndow by dou ble- cl ick ing t he Net work icon.

4. Check your list of Net wor k item s. If TC P/IP is al read y instal led, pr ocee d to step 5. Oth erwis e:
(You may need your Windows CD to complete the installation of TCP/IP.)

 Click the ADD button.
 In the Network Component Type dialog box, select Protocol.
 In the Select Networ k Pro tocol dialog box, select Micr oso ft.
 In the Networ k Prot o co ls a rea o f the same dial o g b o x, select TCP/IP and cl ic k O K.

5. With TCP/IP inst alled , sele ct TCP/I P from t he li st of N etwork Comp onent s.

6. In the TCP/IP window, ch eck e ach of the tabs an d ver ify the f ollow ing sett ing s:

Bindings: Sele ct Client for Microsof t Network s and Fi les and print er shar ing for Micro soft

Networks
Gateway: All fields are blan k.
DNS Configuration: Select Disable DNS.
WINS Configuration: Selec t Use DHCP for WINS Reso lution.
IP address: Select th e Obtai n IP addr ess aut omat ically r adio butt on.

7. Reboot the PC.

Configuring a PC run ning MS- W indow s XP/ 2000:

1. Click the St ar t but to n, and ch oose Cont rol P anel ( in Cl assi c Vie w).

2. In the Control Panel, double-click Network Connections.

3. Double-click Local Area Connection.

4. In the LAN Area Connection Status window, select Internet Protocol (TCP/IP) and click
Properties.

5. Select the Obt a in an IP address au to ma ti ca lly and the Obt ain DN S ser ver addr e ss auto m ati cal ly
radio buttons.

11

6. Click OK to finish the conf igurati on.

Confirming your PC’s IP Configuration:

There are two t ools useful f or fi nd ing ou t a computer's I P add re s s and d efau lt gateway:

WINIPCFG (for Windows 95/98/Me) Select the Start button, and choose Run. Type winipcfg, and a
window will appear li sting t he I P configur ation . You ca n also type winip cfg in the MS-DOS prompt .

The procedure required to set a static IP address is not too much different from the procedure
required to set to “obtain IP addresses dynamically” - except that at the end of step 7, instead of
selecting “obtain IP addresses dynamically, you should specify the IP address explicitly.

Connecting More Devices Through A Hub To The 802.11g Router

The Wireless Router provides four LAN ports to allow up to four PCs or Workstations to be
connected to it direct l y. If yo u want t o conn ect mor e d evic es, you can connect an external hub or
switch to any of the LAN p ort s using a LAN cable.

802.11g Router User’s Guide

Basic Configuration of the 802.11g Router

This section contains basic configuration procedure for the 802.11g Router. It
describes how to set up the 802.11g Router for Internet Access operation, and how
to set up the LAN configur ation .

Although the Command Line Interface (CLI) may also be used to configure the 802.11g Router, the
browser-based configuration mechanism is generally preferred for its ease of use. The Internet
Explorer 6.0 and up are sup po rted .

The 802.11g Router is designed so that all basic configuration may be invoked through the a standard
Web browser such as Internet Expl orer.

To access the WLAN 11g Router’s management interface for the first time, enter the default IP
address of the WLAN 11g Router in your Web browser http://192.168.1.1/

.

Chapter

3

Note: The IP address of your PC must be in the same IP subnet as the 802.11g Router. It is preferred that you
configure the PC to obtain an IP address auto matically from the 802.11g Rou ter.

13

The Home Page of the 802.11g Router screen will appear, with its main menu displayed on the
screen, showing the following top-level choices: Setup Wizard, Device Status, System Tools,
Advanced Setting s, and Hel p. Sele cting any will allow y ou to navi gate to ot her con fi guratio n menus.

Logging On

When you attempt to access a configuration screen from the browser menu, an administrator login
screen will appear, prompting you to enter your password to log on. Once you are logged in, you will
not be asked to log in again unle ss you r “sessi on” expi res su ch as du e to in activ ity t imeout .

If you are logging in for the first time after you received your 802.11g Router, you should use the
factory default pa sswor d, “p assword” to lo g in. (Y ou shou ld ch ange it as soon as aft er you lo g in.)

Characters you type (as your password) will be echoed back as a string of asterisks (“*”) for security
reasons. After you enter the password, clicking the LOG ON button will begin the password
verification pr ocess and, if succ essful , your configu rati on sessi on c an begin.

Note: Should there be no settings or access on the web management screen, system will logout
automatically in 10 minutes.

Setup W iz a rd

The Setup Wizard will guide you through a series of configuration screens to set up the basic
configuration of your 802.11g Router. At the end of the Setup Wizard screens, you should press the
“finish” button, and all your configuration modifications will take effect.

SETTING UP YOUR LOCAL TIME ZONE AND DATE/TIME

After logging in, the Time Settings page appears. The router time will first be set to the local time of
the PC (on which the browser is running). If this time is not correct, modify the appropriate fields as
necessary, and th en cli ck “N EXT”.

14

802.11g Router User’s Guide

DEVICE IP SETTINGS

The Device IP setting screen allows you to configure the IP address and subnet mask of your

802.11g Router: you can conf igur e a stati c IP addr ess an d a subnet mask, or conf igur e it to ob tain an I P

address and a subne t mask automat icall y from a DHCP s erver on th e loc al net work .

If you choose to assign a static IP address manually, check the button that says, “Assign static IP to

this device” and then f i ll i n t he fo llowi n g fi el ds
IP Address and IP Subnet Ma sk: These val ues def au lt to 192.1 68. 1.1 and 255.2 55. 255.0, r espect ively.

This IP address can be modified if necessary, to either a different address in this same subnet or to an
address in a differ ent subne t.

15

When you modify it, if the DHCP server function of your 802.11g Router is enabled, the pool of
IP addresses it will use for assignment purpose s will also be automatcailly adjusted accord in gly. For
example, if the default IP address is used, the IP address pool for assignment consists of addresses
from 192.168.1.2 to 192.168.1.254. However, please do not change the default IP address unless
you know exactly what you wan t to achi eve.

Then you should press Next to get to the next screen.
If you choose to use an external DHCP Server to automatically assign an IP address to your 802.11g

Router, check the button that says, “Use the DHCP protocol to auto matica lly ge t the IP a ddress
for this device”, and then press Next to the next screen.

When an IP address is dynamically assigned to the router, its value can change depending on the IP
address assignment policy used by the DHCP server in the network. Since you need to use an IP
address to control and manage your 802.11g Router, without the knowledge of its IP address, in order
to access it, you will need to use UPnP (Universal Plug and Play) or other management tools that do
not depend on a fixed I P add ress.

It is strongly recom mend ed th at you sel ect the m anual stati c IP add res s.

CONFIGURE THE ISP PROFILE

In the following configuration screen, as with the usual convention, radio buttons are used to
make a selection when only one out of multiple mutually exclusive choices can be selected, while
square check boxe s can be used to select m u ltiple non-m utually-exclusive choices.

When configuring the device for Internet access, decide which one of the following multiple
choices to select (through radio buttons):

1. You can use a static IP ad dress provided by your ISP to connect to the Internet. In this c ase,
you need to configure the following information:

• IP Address Assigned by your ISP: the IP address of the WAN interface of your router.

• IP Subnet Mask: the IP subnet mask of t he WAN interface of your router.

• ISP Gateway IP Address: the I P add ress of your ISP’s Gateway.

•

DNS IP Address: the IP address of the DNS server .

2. You use the user name and password assigned by your ISP to connect to the Internet
(required for the underlying PPPoE protocol). In this case, you need to configure the
following infor m ation:

• User name: the username of your ISP account.

• Password: the passwor d of your ISP account.

• Idle time: The Idle Timeout is the number of seconds of "inactivity" before an

established PPPoE connection is taken down.

16

802.11g Router User’s Guide

The idle time out val ue s hould be b etw een 0 t o 6 0 min ute s, w ith 5 (minu tes) being the de fau lt. A
value of 0 means the connection will never time out.

3. You use DHCP to connect to the Internet (most likely through a cable modem connection).
In this case, your ISP may require you to configure the Host Computer Name:

•

Host Name: The Host Name provided by your ISP.

4. You use PPTP to connect to the Internet. In this case, your ISP requires you to configure
PPTP's tunnel IP address, the username, and password. In this case, configure the static IP
address as in the above and then configure the following information:

• PPTP Local IP Address: the IP address on the local side of the PPTP tunnel provided

by your ISP.

• PPTP IP Netmask: the Netmask on the local side of the PPTP tunnel provided by your

ISP.

• PPTP Remote IP Address: the IP address of the remote side of the PPTP tunnel

provided by your ISP.

• User Name: the username of your ISP account.

• Password: the passwor d of your ISP account.

• Idle time: The Idle Timeout is the number of seconds of "inactivity" before the PPTP

connection is taken down.

0 meaning the connection will never time o ut.

Cloned MAC Address: Some ISPs expect a PC to be connected to their service, and use the MAC
address of this PC’s LAN card for identification purposes. By checking the following “Cloned MAC
address” square check box, your 802.11g Router allows a MAC address to be configured and
“cloned” in the router to simulate a PC.

If the device is a PC based on WIN 95/98/Me, you can run wi nipcfg to find out the MAC Address
of its LAN card. If the device is a PC based on WIN 2000/NT/XP, you need to run "ipconfig/all"
to find out the MAC address of it s LAN card.

Multi pl e D MZ

The router s upports one hardwa re DMZ port, multiple softw are DMZ ports, plus one default
DMZ port.

The hardware DMZ is implemented throu gh the hardware: the rou ter has a separate hardwa re
Ethernet port, to which multiple devices with public IP addresses assigned by the ISP can be
connected. Incoming data for these devices from the Internet will be sent by the router to the
hardware Ethernet port directly. No configuration would be required.

Both the default and mul tiple DMZ ports are implemented through software.
When the router receives incoming data from the Internet, it will search through an internal

address translation table to perform address translation function. If a match cannot be found, the
data will be forwar ded to a special device for processing.

An additional feature is to allow devices with WAN IP addresses to be used by the Internet users
to access private devices in your local LAN. In this case, you need to configure the mapping
between the WAN IP address and the private IP address.

To add the default DMZ, you need to select “Default DMZ” and enter the local DMZ IP
address, followed by pressing the ADD button.

To add a device for multiple DMZ, first select “Multiple DMZ”, add a name, a public WAN
IP address , and the local DMZ IP address on the LAN, followed by pressing the ADD button.

You can delete a DMZ entry by selecting the corresponding entry and press the DELETE
SELECTED button.

29

Virtual Server Settings

A Virtual Server is a server built on a single or a cluster of real servers. A DMZ server is a term
commonly used to describe the default Virtual Server - the router will redirect all traffic from the
Internet witho ut a vali d port addres s mapping to th is device . An HTTP se rver with a p rivate IP
address on the LAN allows access from the Internet by mapping a special port to the HTTP
server. In this case , th e HTTP service will be mapped to a port of the Rout e r.

You can add a virtual server mapping by (1) selecting the service name (such as HTTP, FTP,
TELNET, SMTP, POP3, CUSTOM), (2) enter the public port number to be used (either a
single port number or a range), (3) enter t he local IP address of the server on your LAN, (4)
enter its local port number to map to (either a single port number or the starting port number
of a range), (5) followed by pressing th e ADD button.

You can delete a mapping by selecting the corresponding entry and press the DELETE
SELECTED button.

Note: Virtual Server Setting and IP Filtering may affect with each other.

IP Routing Settings

Dynamic Routing: enable g ateway to c hange t he ro utin g table dyn amic ally th rough LAN por t.
Static Routing:

If you have routers on your LAN or WAN, you can configure static routes on the

802.11g Router to route network traffic to a specific, predefined destination. The 802.11g Router
can route packets based only on the packet's destination not on the source of a packet. Static
routes must be defined if the LAN or WAN are segmented into subnets. For example, a subnet
can be created to isolate a section of a company, such as finance, from traffic on the rest of the
LAN or WAN.

Static Routes are configured when network traffic is directed to a specific destination on the network

whether it is the LAN or WAN. For instance, you can configure the 802.11g Router to route
traffic from a computer, 192.168.1.100, on the LAN to a specific computer on the LAN,

192.168.168.2 7 usi n g the f o llo wing st ep s:

802.11g Router User’s Guide

Wireless Settings

You can use this screen to conf igure var ious param eter s of your 802 .11g Rout er.
Beacon Interval: The 802.11g Router broadcasts beacon frames regularly to announce its existence.

The beacon Interval specifies how often beacon frames are transmitted - in time unit of milliseconds.
Its default value is 10 0; a va lid valu e shoul d be betwe en 1 and 10 00.

RTS Threshold: RTS/CTS frames are used to gain control of the medium for transmis sion. Any
unicast (data or control) frames larger than specified RTS threshold must be transmitted following the
RTS/CTS handshake exchange mechanism. The RTS threshold should have a value between 256-

37

2432 bytes, with a default value of 2432. A value of zero activates the RTS/CTS handshake before
every transmiss ion. It is rec ommende d that t his val ue does not devi ate fr om the d efault too muc h.

Fragmentation: When the size of a unica st frame exceeds the fragmentation thr eshold, the frame wil l
be fragmented before transmission. The threshold should have a value of 256-2346 bytes, with a
default value of 2346. If you experience a high packet error rate, you should slightly decrease the
Fragmentation Threshol d.

DTIM Interval: The 802.11g Router buffers packets for stations that operate in the power-saving
mode. A Delivery Traffic Indication Message (DTIM) contains information on which power­conserving stations have packets waiting to be received. The DTIM interval specifies how often
beacon frames should contain DTIMs. It should have a value between 1 and 65535, with a default
value of 3.

RADIUS Settings

RADIUS (Remote Access Dial In Service) servers provide centralized authentication services to
wireless clients. Up to two RADIUS servers can be defined, one acting as a primary, and the other
acting as a backup .

Enable Primary Server: To configure the primary server, check the “Enable Primary Server” box,
and configure the f ollowi ng param eters:

Authenticate: Two user authentication methods can be enabled: one based on MAC address f ilt er , th e
other based on 802.1 x EAP/MD 5. You can s ele ct eith er or both .

38

802.11g Router User’s Guide

MAC address filtering based authentication requires a MAC address filter table to be created in
either the 802.11g Router and/or the RADIUS server. During the Authentication phase, the
MAC address filter table is searched for a match against the wireless client’s MAC add ress to
determine whet her the st ati on is to b e allowed or deni ed t o acces s the netw ork.

The RADIUS server can also be used for 802.1x EAP/MD5 authentication. IEEE 802.1x is an
IEEE standard which is based on a framework that involves stations to be authenticated (called
Supplicant), an authentication server (a RADIUS Server) that provides authentication services,
and an authenticator that provides necessary translation and mediating functions between the
authentication serv er and statio ns to b e auth enticat ed, i n this c ase your 802.11 g Rout er.

During EAP authentication, the 802.11g Router relays authentication messages between the
RADIUS server and c lient s being authent icated .

Server IP: The IP addr ess of the RADIUS ser ver
Port Number: The port number your RADIUS server uses for authentication. The default setting is

1812.
Shared Secret: This is used by your RADIUS server in the Shared Secret field in RADIUS protocol

messages. The sh ar ed secret configu red i n th e 802 .11g Router must m atch t h e sha r ed secr et co nfi g ured
in the RADIUS ser ver. The shared secret can con tain u p to 64 alp hanu meri c chara cter s.

Time Out: The number of seconds the 802.11g Router should wait before authentication is
considered to h av e f a iled in the Ret r y Tim es ( se c) f ield.

Retry Times: The number of times the 802.11g Router should attempt to contact the primary server
before giving up.

Enable Secondary Server: To configure the secondary server, check the “Enable Secondary Server”
box, and configure the same par ameter s as for the pr imar y ser ver.

RADIUS Server Reattempt Period: This is the amount of time the router will wait before it will try
to reconnect to the primary RADIUS server if the secondary RADIUS server is in operation at the
time, and vice ver sa.

39

Dynamic DNS Settings

Some people advertise the IP addresses of their routers so that Internet users c

an access these
routers (which is really to access virtual servers behind these routers) using these IP addresses.
However, for those routers that are assigned dynamic IP addresses from the ISP, since IP
addresses change, this approach requires additional work.

The 802.11g Router implements the dynamic DNS feature so that each time it is booted, it will
re-register its domain-name-to-IP-address mapping with DynDNS.org, the standards
organization that provides domain name to IP address mapping. This is so that you can advertise
your router by providing your domain name, while Internet users can access the router using the
domain name, not the router’s IP address.

To activate this feature, you need to check the “Enable Dynamic DNS Client using

DynDNS.org” box first, and then configure the following parameter s:
Hostname: the hostname (domain name) registered with DynDNS.org by you.

40

802.11g Router User’s Guide

Username: the username required to log in to the domain name server maintained by

Most commands are sin gle- l ine co m mand s, and com m ands ar e not cont ext sen s it iv e: eac h comm an d is

The command syntax is straightf or war d.
The following briefly summarize s the guideline for the interface.
 At any time, the user can type a “?” (preceded by a space) to request context-sensitive help on

what the user can en ter ne xt.

will be displa yed, and the user can

command. Note

 At any time, the user can type control-p (^p, by pressing both the Ctrl key and the p key at the

same time) to repeat the previous command, or control n to return to the following (next)
command. At startup, typing ^p or ^n will not cause anything to happen - since previous

802.11g Router User’s Guide

commands do not yet exist. In normal operation, typing ^p will cause the previous command to
show, and the cursor will sit at the end of the command. At this point, the user can either type a
carriage return to accept the command, or type backspaces to edit the command from the end.
Up to 15 previously ent ere d commands can be invok ed th rough ^p ’s and ^n ’s.

 If a keyword is expected when the user types “ ?”, all valid keywords will be displayed. The

command typed in so far will then be displayed again along with the cursor sitting at the end,
waiting for the us er to conti nue.

 If the user types in part of the keyword but does not type in the entire word, the user can then

enter a tab or space for the system to automatically complete the keyword if the characters typed
in so far can uniquely identify the keyword. If the characters typed in so far do not uniquely
identify a keyword , a li st of po ssible k eywor ds wil l be di spl ayed.

If the user is not sure what to type next, he or she can type "?” to display the possible keywords
that match the current CLI command input.

If an interactive mode is entered, the system will prompt for each required parameter, such as:

…

select regulatory domain (fcc, fcc/etsi/france/spain/japan):
enter channel number (10, 1-14):

…

The first prompt means there are five choices (FCC, ETSI, France, Spain, or Japan), with FCC
being the default. The second prompt means a number between 1 and 14 is expected, with 10
being the default.

During the first time a particular parameter is configured, typing a carriage return will cause the
default value to be selected. Otherwise, typing a carriage return means no change to the current
value.

Express Mode vs. Advanced Mode of operation

The Command Line Interface operates in one of two modes:

Mode

. In Express Mode, not all parameters are displayed. Default values are set for those
parameters not displayed in mult i-line commands. In Advanced Mode , users have the opti on to
modify all possib le values appropriate to each operation.

The user can toggle between Express Mode and Advanced Mode by typing ^E (Control-E) at any
time. Normally, the system prompt will be changed by appending “>>” to the configured prompt
when in Advanced Mode.

 [ ] indicates a required or o ptio nal paramet er , or choi ce of par ameter s;
 MacAddr, or XX-XX-XX-XX-XX-XX means any MAC address in hexadecimal format,

where each XX can be 00, 01, ... 99, 0A, 0B, 0C, 0D, 0E, 0F, 10, 11,… FF;

 ipAddr, netmask, or xxx.xxx.xxx.xxx means any ip address or network mask, where xxx is a

decimal integer bet ween 0 a nd 255;

 the term string means a string of characters up to the specified length, which may be enclosed

in double quotes (“) (requir ed if the st ring cont ain s embedd ed blank s;

 Names representing filters and MAC addresses should be up to 30 characters in length;

password and SNMP community read/write strings are up to 15 characters in length. When
the password and SNMP community writ e string are enter ed, they are echoed back as a string
of “*”s for protection, while other parameters, such as WEP keys, are echoed back the way
they are typed (i n cl ear text ) .
