CHAPTER 5: CONFIGURING THE ROUTER
Proxy ARP
Proxy ARP is the technique in which one host, usually a router, answers
ARP requests intended for another machine. By "faking" its identity, the
router accepts responsibility for routing packets to the "real" or intended
destination. This hightens the security for your network.

The Router keeps time by connecting to a Network Time Protocol (NTP)
server. This allows the Router to synchronize the system clock to the
Internet. The synchronized clock in the Router is used to record the
security log and control client filtering. Select the time zone that you
reside in. If you reside in an area that observes Daylight Saving, then
check the checkbox for Enable Daylight Saving. The system clock may not
update immediately. Allow at least 15 minutes for the router to contact
the time servers on the Internet and get a response. You cannot set the
clock yourself.
You can specify which NTP servers the Router will use to update the
system clock, although doing this should only be necessary if you are
experiencing difficulty.

TROUBLESHOOTING
■
Check that the Router is connected to your computers and to the
telephone line, and that all the equipment is powered on. Check that
the LAN Status and SYNC LEDs on the Router are illuminated, and that
any corresponding LEDs on the NIC are also illuminated.
■
Ensure that the computers have completed their start-up procedure
and are ready for use. Some network interfaces may not be correctly
initialized until the start-up procedure has completed.
■
If the link status LED does not illuminate for a port that is connected,
check that you do not have a faulty cable. Try a different cable.
If you have connected your Router and computers together but cannot
browse to the Router configuration screens, check the following:
■
Confirm that the physical connection between your computer and the
Router is OK, and that the LAN Status LEDs on the Router and
network adapter are illuminated and indicating the same speed
(10Mbps or 100Mbps). Some NICs do not have status LEDs, in which
case a diagnostic program may be available that can give you this
information.
■
Ensure that you have configured your computer as described in
Chapter 3. Restart your computer while it is connected to the Router
to ensure that your computer receives an IP address.
■
When entering the address of the Router into your web browser,
ensure that you use the full URL including the http:// prefix (e.g.
http://192.168.1.1).
■
Ensure that you do not have a Web proxy enabled on your computer.
Go to the Control Panel and click on Internet Options. Select the
Connections tab and click on the LAN Settings button at the bottom.
Make sure that the Proxy Server option is unchecked.
104
CHAPTER 6: TROUBLESHOOTING
■
Connecting to the
Internet
Forgotten Password
and Reset to
Factory Defaults
If you cannot browse to the Router, use the winipcfg utility in
Windows 98/ME to verify that your computer has received the correct
address information from the Router. From the Start menu, choose
Run and then enter winipcfg. Check that the computer has an IP
address of the form 192.168.1.xxx (where xxx is in the range 2-254),
the subnet mask is 255.255.255.0, and the default Router is
192.168.1.1 (the address of the Router). If these are not correct, use
the Release and Renew functions to obtain a new IP address from the
Router. Under Windows 2000 and Windows XP, use the ipconfig
command-line utility to perform the same functions.
If you can browse to the Router configuration screens but cannot access
web sites on the Internet, check the following:
■
Confirm that the physical connection between the Router and the
telephone line is OK, and that the DSL LED on the Router is
illuminated.
■
Ensure that you have entered the correct information into the Router
configuration screens as required by your Internet Service Provider. Use
the Internet Settings screen to verify this.
■
Check that the PPPoE or PPPoA user name and password are correct.
■
Ensure that your computers are not configured to use a Web proxy.
On Windows computers, this can be found under Control Panel >
Internet Options > Connections.
If you can browse to the Router configuration screen but cannot log on
because you do not know or have forgotten the password, follow the
steps below to reset the Router to its factory default configuration.
CAUTION: All your configuration changes will be lost, and you will need
to run the configuration wizard again before you can re-establish your
Router connection to the Internet. Also, other computer users will lose
their network connections whilst this process is taking place, so choose a
time when this would be convenient.
1 Power off the Router.
2 Disconnect all your computers and the telephone line from the Router.
3 Re-apply power to the Router, and wait for it to finish booting up.
Wireless Networking
105
4 Press and hold the Reset button on the rear panel (see “The rear panel
(Figure 4) of the Router contains four LAN ports, one ADSL port, a reset
button, a power switch, and a power adapter socket.” on page 15) for 5
seconds.
5 The Router will restart, and when the start-up sequence has completed,
browse to:
http://192.168.1.1
and run the configuration wizard. You may need to restart your computer
before you attempt this.
6 When the configuration wizard has completed, you may reconnect your
network as it was before.
Wireless
Networking
■
Ensure that you have an 802.11b or 802.11g wireless adapter for
each wireless computer, and that it is correctly installed and
configured. Verify that each Wireless computer has either Windows
98 or higher or MAC OS 8.5 or higher.
■
Verify that your wireless computers are configured to work in
Infrastructure mode and not Ad Hoc mode. The Router contains an
Access Point that is designed to operate in Infrastructure mode. Ad
Hoc mode is not supported by the Router.
■
If you have a wired and a wireless NIC in the same computer, ensure
that the wired NIC is disabled.
■
Check the status of the WLAN LED, it should be lit if wireless is
enabled and will flash when there is wireless activity. If not lit go to
“Wireless Settings” on page 43 and enable wireless networking.
■
Ensure that the TCP/IP settings for all devices are correct.
■
Ensure that the Wireless Clients are using the same SSID or Service
Area Name as the Router. The SSID is case-sensitive
■
Ensure that the encryption method and level that you use on your
clients are the same as those configured on the Router. The Router
cannot simultaneously support WPA and WEP encryption.
■
Ensure that you have the Wireless computer enabled in the list of
allowed MAC addresses if you are using MAC Address Filtering on the
Router.
■
If you are having difficulty connecting or are operating at a low speed
try changing the antenna positions on the rear of the Router. For more
106
CHAPTER 6: TROUBLESHOOTING
effective coverage you can try reorientating your antennae. Place one
antenna vertically and one horizontally to improve coverage.
Additionally consider moving the wireless computer closer to the
Router to confirm that the building structure or fittings are not
adversely affecting the connectivity. If this resolves the problem
consider relocating the Wireless computer or the Router, or trying a
different channel on the Router.
■
Sources of interference: The 2.4Ghz ISM band is used for 802.11b and
802.11g. This is generally a licence free band for low power
applications, and you may have other devices at your location that
operate in this frequency band. You should take care to ensure that
there are no devices like microwave ovens for example close to the
Router or wireless computers as this could affect receiver sensitivity
and reduce the performance of your network. If you are unsure try
relocating both the wireless computers and the Router to establish
whether this problem exists.
■
Most wireless computer Adapters will scan the channels for the
wireless Router. If a wireless computer has not located the Router then
try initiating a search manually if the client software supports this
feature or manually set the channel on your wireless computer to
correspond to the Router channel number. Please refer to your
Wireless computer adapter documentation and vendor to do this.
■
Speed of connection: The 802.11b and 802.11g standards will
automatically choose the best speed depending on the quality of your
connection. As the signal quality weakens then the speed falls back to
a lower speed. The speeds supported by 802.11g are 54 Mbps,
48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, and 6 Mbps. The
speeds supported by 802.11b are 11 Mbps, 5.5 Mbps, 2 Mbps and
1 Mbps. In general the closer you are to the Router the better the
speed. If you are not achieving the speed you had anticipated then try
moving the antenna on the Router or moving the Wireless computer
closer to the Router. In an ideal network the Router should be located
in the centre of the network with Wireless computers distributed
around it. Applications are generally available with the computer
wireless card to carry out a site survey. Use this application to find the
optimal siting for your wireless computer. Consult your Computer
Card documentation and vendor for more details.

A
IP ADDRESSING
The Internet
Protocol Suite
The Internet protocol suite consists of a well-defined set of
communications protocols and several standard application protocols.
Transmission Control Protocol/Internet Protocol (TCP/IP) is probably the
most widely known and is a combination of two of the protocols (IP and
TCP) working together. TCP/IP is an internationally adopted and
supported networking standard that provides connectivity between
equipment from many vendors over a wide variety of networking
technologies.
Managing the
Router over the
Network
To manage a device over the network, the Router must be correctly
configured with the following IP information:
IP Addresses and
Subnet Masks
■
An IP address
■
A Subnet Mask
Each device on your network must have a unique IP address to operate
correctly. An IP address identifies the address of the device to which data
is being sent and the address of the destination network. IP addresses
have the format n.n.n.x where n is a decimal number between 0 and 255
and x is a number between 1 and 254 inclusive.
However, an IP Address alone is not enough to make your device operate.
In addition to the IP address, you need to set a subnet mask. All networks
are divided into smaller sub-networks and a subnet mask is a number
that enables a device to identify the sub-network to which it is
connected.
110
APPENDIX A: IP ADDRESSING
For your network to work correctly, all devices on the network must have:
■
The same sub-network address.
■
The same subnet mask.
The only value that will be different is the specific host device number.
This value must always be unique.
An example IP address is ‘192.168.100.8’. However, the size of the
network determines the structure of this IP Address. In using the Router,
you will probably only encounter two types of IP Address and subnet
mask structures.
Type One
In a small network, the IP address of ‘192.168.100.8’ is split into two
parts:
■
Part one (‘192.168.100’) identifies the network on which the device
resides.
■
Part two (‘.8’) identifies the device within the network.
This type of IP Address operates on a subnet mask of ‘255.255.255.0’.
See Table 3 for an example about how a network with three computers
and a Router might be configured.
Table 3 IP Addressing and Subnet Masking

255.255.255.0
Router
192.168.100.72
255.255.255.0
Type Two
In larger networks, where there are more devices, the IP address of
‘192.168.100.8’ is, again, split into two parts but is structured differently:
■
Part one (‘192.168’) identifies the network on which the device
resides.
■
Part two (‘.100.8’) identifies the device within the network.
How does a Device Obtain an IP Address and Subnet Mask?
111
This type of IP Address operates on a subnet mask of ‘255.255.0.0’.
See Table 4 for an example about how a network (only four computers
represented) and a Router might be configured.
Table 4 IP Addressing and Subnet Masking

There are three different ways to obtain an IP address and the subnet
mask. These are:
■
Dynamic Host Configuration Protocol (DHCP) Addressing
■
Static Addressing
■
Automatic Addressing (Auto-IP Addressing)
The Router contains a DHCP server, which allows computers on your
network to obtain an IP address and subnet mask automatically. DHCP
assigns a temporary IP address and subnet mask which gets reallocated
once you disconnect from the network.
DHCP will work on any client Operating System such as Windows® 95,
Windows 98 or Windows NT 4.0. Also, using DHCP means that the same
IP address and subnet mask will never be duplicated for devices on the
network. DHCP is particularly useful for networks with large numbers of
users on them.
Static Addressing
Auto-IP Addressing
You must enter an IP Address and the subnet mask manually on every
device. Using a static IP and subnet mask means the address is
permanently fixed.
Network devices use automatic IP addressing if they are configured to
acquire an address using DHCP but are unable to contact a DHCP server.
Automatic IP addressing is a scheme where devices allocate themselves
112
APPENDIX A: IP ADDRESSING
an IP address at random from the industry standard subnet of
169.254.x.x (with a subnet mask of 255.255.0.0). If two devices allocate
themselves the same address, the conflict is detected and one of the
devices allocates itself a new address.
Automatic IP addressing support was introduced by Microsoft in the
Windows 98 operating system and is also supported in Windows 2000.

APPENDIX D: OBTAINING SUPPORT FOR YOUR PRODUCT
GLOSSARY
802.11b
The IEEE specification for wireless Ethernet which allows speeds of up to
11 Mbps. The standard provides for 1, 2, 5.5 and 11 Mbps data rates.
The rates will switch automatically depending on range and environment.
802.11g
The IEEE specification for wireless Ethernet which allows speeds of up to
54 Mbps. The standard provides for 6, 12, 24, 36, 48 and 54 Mbps data
rates. The rates will switch automatically depending on range and
environment.
10BASE-T
The IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5
twisted pair cable.
100BASE-TX
The IEEE specification for 100 Mbps Fast Ethernet over Category 5
twisted-pair cable.
Access Point
An Access Point is a device through which wireless clients connect to
other wireless clients and which acts as a bridge between wireless clients
and a wired network, such as Ethernet. Wireless clients can be moved
anywhere within the coverage area of the access point and still connect
with each other. If connected to an Ethernet network, the access point
monitors Ethernet traffic and forwards appropriate Ethernet messages to
the wireless network, while also monitoring wireless client radio traffic
and forwarding wireless client messages to the Ethernet LAN.
Ad Hoc mode
Ad Hoc mode is a configuration supported by most wireless clients. It is
used to connect a peer to peer network together without the use of an
access point. It offers lower performance than infrastructure mode, which
is the mode the router uses. (see also Infrastructure mode.)
130
GLOSSARY
Auto-negotiation
Some devices in the range support auto-negotiation. Auto-negotiation is
where two devices sharing a link, automatically configure to use the best
common speed. The order of preference (best first) is: 100BASE-TX full
duplex, 100BASE-TX half duplex, 10BASE-T full duplex, and 10BASE-T
half duplex. Auto-negotiation is defined in the IEEE 802.3 standard for
Ethernet and is an operation that takes place in a few milliseconds.
Bandwidth
The information capacity, measured in bits per second, that a channel can
transmit. The bandwidth of Ethernet is 10 Mbps, the bandwidth of Fast
Ethernet is 100 Mbps. The bandwidth for 802.11b wireless is 11Mbps.
Category 3 Cables
One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586
standard. Category 3 is voice grade cable and can only be used in
Ethernet networks (10BASE-T) to transmit data at speeds of up to 10
Mbps.
Category 5 Cables
One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586
standard. Category 5 can be used in Ethernet (10BASE-T) and Fast
Ethernet networks (100BASE-TX) and can transmit data up to speeds of
100 Mbps. Category 5 cabling is better to use for network cabling than
Category 3, because it supports both Ethernet (10 Mbps) and Fast
Ethernet (100 Mbps) speeds.
Channel
Similar to any radio device, the Wireless Cable/DSL router allows you to
choose different radio channels in the wireless spectrum. A channel is a
particular frequency within the 2.4GHz spectrum within which the Router
operates.
Client
The term used to described the desktop PC that is connected to your
network.
DHCP
Dynamic Host Configuration Protocol. This protocol automatically assigns
an IP address for every computer on your network. Windows 95,
Windows 98 and Windows NT 4.0 contain software that assigns IP
addresses to workstations on a network. These assignments are made by
the DHCP server software that runs on Windows NT Server, and Windows
95 and Windows 98 will call the server to obtain the address. Windows
98 will allocate itself an address if no DHCP server can be found.
GLOSSARY
DNS Server Address
DSL modem
131
DNS stands for Domain Name System, which allows Internet host
computers to have a domain name (such as 3com.com) and one or more
IP addresses (such as 192.34.45.8). A DNS server keeps a database of
host computers and their respective domain names and IP addresses, so
that when a domain name is requested (as in typing “3com.com” into
your Internet browser), the user is sent to the proper IP address. The DNS
server address used by the computers on your home network is the
location of the DNS server your ISP has assigned.
DSL stands for digital subscriber line. A DSL modem uses your existing
phone lines to send and receive data at high speeds.
Encryption
A method for providing a level of security to wireless data transmissions.
The Router uses two levels of encryption; 40/64 bit and 128 bit. 128 bit is
a more powerful level of encryption than 40/64 bit.
ESSID
Extended Service Set Identifier. The ESSID is a unique identifier for your
wireless network. You must have the same ESSID entered into the router
and each of it's wireless clients.
Ethernet
Ethernet Address
Fast Ethernet
A LAN specification developed jointly by Xerox, Intel and Digital
Equipment Corporation. Ethernet networks use CSMA/CD to transmit
packets at a rate of 10 Mbps over a variety of cables.
See MAC address.
An Ethernet system that is designed to operate at 100 Mbps.
Firewall
Electronic protection that prevents anyone outside of your network from
seeing your files or damaging your computers.
Full Duplex
A system that allows packets to be transmitted and received at the same
time and, in effect, doubles the potential throughput of a link.
Half Duplex
A system that allows packets to transmitted and received, but not at the
same time. Contrast with full duplex.
132
GLOSSARY
Hub
A device that regenerates LAN traffic so that the transmission distance of
that signal can be extended. Hubs are similar to repeaters, in that they
connect LANs of the same type; however they connect more LANs than a
repeater and are generally more sophisticated.
IEEE
Institute of Electrical and Electronics Engineers. This American
organization was founded in 1963 and sets standards for computers and
communications.
IETF
Internet Engineering Task Force. An organization responsible for
providing engineering solutions for TCP/IP networks. In the network
management area, this group is responsible for the development of the
SNMP protocol.
Infrastructure mode
Infrastructure mode is the wireless configuration supported by the Router.
You will need to ensure all of your clients are set up to use infrastructure
mode in order for them to communicate with the Access Point built into
your Router. (see also Ad Hoc mode)
IP
Internet Protocol. IP is a layer 3 network protocol that is the standard for
sending data through a network. IP is part of the TCP/IP set of protocols
that describe the routing of packets to addressed devices. An IP address
consists of 32 bits divided into two or three fields: a network number and
a host number or a network number, a subnet number, and a host
number.
IP Address
Internet Protocol Address. A unique identifier for a device attached to a
network using TCP/IP. The address is written as four octets separated with
periods (full-stops), and is made up of a network section, an optional
subnet section and a host section.
IPsec
IP Security. Provides IP network-layer encryption. IPSec can support large
encryption networks (such as the Internet) by using digital certificates for
device authentication. When setting up an IPSec connection between
two devices, make sure that they support the same encryption method.
ISP
Internet Service Provider. An ISP is a business that provides connectivity to
the Internet for individuals and other businesses or organizations.
GLOSSARY
LAN

Local Area Network. A network of end stations (such as PCs, printers,
servers) and network devices (hubs and switches) that cover a relatively
small geographic area (usually not larger than a floor or building). LANs
are characterized by high transmission speeds over short distances (up to
1000 metres).
MAC
Media Access Control. A protocol specified by the IEEE for determining
which devices have access to a network at any one time.
MAC Address
Media Access Control Address. Also called the hardware or physical
address. A layer 2 address associated with a particular network device.
Most devices that connect to a LAN have a MAC address assigned to
them as they are used to identify other devices in a network. MAC
addresses are 6 bytes long.
NAT
Network Address Translation. NAT enables all the computers on your
network to share one IP address. The NAT capability of the Router allows
you to access the Internet from any computer on your home network
without having to purchase more IP addresses from your ISP.
Network
A Network is a collection of computers and other computer equipment
that are connected for the purpose of exchanging information or sharing
resources. Networks vary in size, some are within a single room, others
span continents.
Network Interface
Card (NIC)
Protocol
A circuit board installed into a piece of computing equipment, for
example, a computer, that enables you to connect it to the network. A
NIC is also known as an adapter or adapter card.
A set of rules for communication between devices on a network. The
rules dictate format, timing, sequencing and error control.
PPPoE
Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method
of data transmission originally created for dial-up connections; PPPoE is
for Ethernet connections.
PPTP
Point-to-Point Tunneling Protocol is a method of secure data transmission

RJ-45
A standard connector used to connect Ethernet networks. The “RJ”
stands for “registered jack”.
Router
A device that acts as a central hub by connecting to each computer's
network interface card and managing the data traffic between the local
network and the Internet.
Server
A computer in a network that is shared by multiple end stations. Servers
provide end stations with access to shared network services such as
computer files and printer queues.
SSID
Service Set Identifier. Some vendors of wireless products use SSID
interchangeably with ESSID.
Subnet Address
An extension of the IP addressing scheme that allows a site to use a single
IP network address for multiple physical networks.
Subnet mask
A subnet mask, which may be a part of the TCP/IP information provided
by your ISP, is a set of four numbers configured like an IP address. It is
used to create IP address numbers used only within a particular network
(as opposed to valid IP address numbers recognized by the Internet,
which must assigned by InterNIC).
Subnets
A network that is a component of a larger network.
Switch
A device that interconnects several LANs to form a single logical LAN that
comprises of several LAN segments. Switches are similar to bridges, in
that they connect LANs of a different type; however they connect more
LANs than a bridge and are generally more sophisticated.
TCP/IP
Transmission Control Protocol/Internet Protocol. This is the name for two
of the most well-known protocols developed for the interconnection of
networks. Originally a UNIX standard, TCP/IP is now supported on almost
all platforms, and is the protocol of the Internet.
TCP relates to the content of the data travelling through a network —
ensuring that the information sent arrives in one piece when it reaches its
destination. IP relates to the address of the end station to which data is
being sent, as well as the address of the destination network.
GLOSSARY
