Troubleshooting



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.



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 informa-

tion from the Router. From the Start menu, choose Run and then enter

winipcfg

Check

that

the

computer

has

address

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 Win-

dows XP, use the

ipconfig

command-line utility to perform the same func-

tions.

CONNECTING TO THE

INTERNET

If you can browse to the Router configuration screens but cannot access 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 GREEN on.



Ensure that you have entered the correct information into the Router configu-

ration screens as required. Use the “Internet Settings” screen to verify this.



Check that the user name and password are correct.



Ensure that your computers are not configured to use a Web proxy. On Win-

dows computers, this can be found under Control Panel >Internet Options >

Connections.

FORGOTTEN PASSWORD

AND RESET TO FACTORY

DEFAULTS

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 it’s factory default configuration.

All your configuration changes will be lost, and you will need to configure again your network 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 conven-

ient.

Switch off the Router.

Disconnect all your computers and the telephone line from the Router.

Re-apply power to the Router, and wait for it to finish booting up.

Press the Reset button on the rear panel for a while.

The Router will restart, and when the start-up sequence has completed,

browse to: http://192.168.1.1 and configure your network.

Reconnect your network as it was before.

WIRELESS NETWORKING



Ensure that you have an 802.11b, 802.11g or 802.11n wireless adapter for

each wireless computer, and that it is correctly installed and configured. Ver-

ify that each Wireless computer has either Windows 98SE or higher or MAC

OS 10.x or higher.



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 Router Wireless LED.



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 simultane-

ously 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 effective

coverage you can try reorientating your antenna. Additionally consider mov-

ing the wireless computer closer to the Router to confirm that the building

structure or fittings are not adversely affecting the connectivity. If this re-

solves 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, 802.11g

and 802.11n. This is generally a licence free band for low power applica-

tions, 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/g and 802.11n standards will automati-

cally 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. And the 802.11n supports until

100Mbps.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 an-

tenna 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.

FREQUENTLY ASKED

QUESTIONS

How do I reset the Router to Factory Defaults?

See How To “... change the

administrator password”.

How many computers on the LAN does the Router support?

Up to a maxi-

mum of 256 computers on the LAN are supported.

The Quality of Service (QoS) is related to the guaranteed level of throughput (the amount of data

transferred from the Router to the clients). As many clients are connected as lower is the Quality as

Service.

How many wireless clients does the Router support?

A maximum of 15

wireless clients are supported.

How are additional computers connected?

You can expand the number of

connections available on your LAN by using hubs, switches and wireless ac-

cess points connected to the Router. Wireless access points and hubs and

switches provide a simple, reliable means of expanding your network; contact

your supplier for more information, or visit: http://www.pirelli.com/

The crossed-out wheeled bin symbol on this electric or electronic equipment, or on its packaging, indi-

cates that, at the end of its life, it must not be disposed of as unsorted household waste. Instead it must

be separately collected.

As a consumer you must, therefore, use the specific collection schemes and, in particular, the municipal

collection schemes provided for waste electrical and electronic equipment.

The separate collection and appropriate treatment of the equipment at the time of disposal helps to con-

serve natural resources and to ensure that it is recycled in a manner that protects human health and the

environment from materials, components and substances that can be dangerous to the environment and

harmful to human health.

Furthermore, the separate collection and appropriate treatment of the equipment, at the time of disposal,

facilitates its possible reuse or possible materials recovery.
