In this Article, Linksys equipment is specified, however equivalents are available from a number of manufacturers, and this does not constitute a recommendation of Linksys over other manufacturers.

Note: although most Cable Modems are supplied with an Ethernet and USB connection, in general only one of these can be used at a time as only a single IP address is allocated to the Cable Modem.

There was an exception to this in that ntl: used to supply the "Console Service" which allocated two IP addresses to the Cable Modem. However this service is now discontinued from sale.

The following diagram assumes that 2 PCs and 1 Laptop will be connected.

The Router is connected to the Cable Modem or Set Top Box (STB) by a network cable known as a CAT5 cable. This cable can in theory be up to 100 metres long so the Router can be next to the Cable Modem / STB or in a different part of the house.

One Desktop PC is next to the Router and uses another CAT5 cable to connect. To do this it will need a Network Adapter (aka Ethernet Card or NIC) to be installed

The second Desktop PC is connected wirelessly using a USB Network Adapter.

The Laptop can be connected by a USB Network Adapter, or a Notebook Adapter (PC Card)

Four Tips:

Make sure you take a look at the website of the manufacturer and get the latest software drivers etc.

Whenever you change a connection to a Cable Modem or STB always power it off for 30 seconds then back on for a minute before powering up the new device.

Set the Router up with a wired connection first if you can. There are a lot of variables (aka "things to go wrong") with wireless!

Always set up security settings on wireless! If not your neighbours can use your service for free, and if they do something inappropriate it looks like you did it.

Power everything down.
First of all the cablemodem will plug into the back of the wrt54g. into the Internet port or the WRT54G.

The WPC54g will go into the Laptop, and the WUSB54G onto the Desktop.

When you connect The WRT54g power off your cablemodem and your WRT54G.
Wait 30 seconds then power up the CM first. Wait until diagnostics has run and modem is ready. Now power on WRT54G, leave it to do its diagnostics etc., for a couple of minutes.

For setup purposes of the WRT54G i would strongly advise you to first add the laptop to the port 1 on the WRT54G using the ethernet connection. this is so you can setup the wireless side of the Router first of all.

to get to the setup open you browser and type 192.168.1.1

username: root
password: admin

then you will see the setup of the WRT54G. goto wireless.

http://192.168.1.1/Wireless_Basic.asp

set wireless mode to G only

SSID to whatever you like.

Channel 11 seems to be overall best.

as to enabling SSID i would use this to start with....

click on save settings

then click on next tab Wireless security

Set to WPA PreShared Key
AES
and a password of your choosing
group renewal 3600

Then click on save settings.

Now exit router setup. and disconnect router from laptop. now plug in WPC54G and setup the drivers. a reboot may be required.

Once rebooted then you'll need the WPC54G software to reconsing the wireless connection by adding the WPA PSK, AES and Password settings to it.

Once this is done you should be able to surf ok then using the laptop.
