Setting up a wireless network is a common business in todays cmputing world. Windows 2000,XP,Vista makes it easy to setup a wi-fi network.
For a wi-fi network you need:
ISP internet account
computers with wireless card
optional gateway
Most wireless cards are either PCI interface for desktop PC’s or PCMCIA cards for laptops. USB wireless cards will work for both laptops or PC’s.
It’s a good idea to install the drivers or software for any wireless device you have before actually connecting the device to the computer. This software should come with the device or be available for download from the manufacturers website.
Once software is installed, XP can be configured to utilize windows wireless network manager or use a third party wireless network managing software.
Configure Your Computers For Wireless Network
These settings need to be made to your computers that will be in your wireless network
These images are Vista but Xp/2000 are very similar.
In Vista/XP/2000:
Click start
Right click network
In Vista you see Network and sharing Menu first - Under Tasks click Manage Network Connections
You should Find your wireless card listed here, highlight it,
Right click
Click properties (you may need to enter an administrators password)
Highlight TCP/IP
Click properties
Check both Obtain IP address automatically, Obtain DNS address automatically

Using and Setup a Wireless Gateway/Router
A gateway is the physical routing device that connects your DSL/Cable signal from the phone company to your computer network. If you use a wireless gateway device these are the steps you have to take to make it work:
Connect the gateway to your phone line or cable modem box (to ensure that you see a green indication for a live internet connection on your cable modem and gateway you may need to power off both devices one at a time - start with the cable modem)
Usually you need to configure the wireless options of your gateway before you can use the wireless capability.
Connect an ethernet cable from the gateway to your computer so you can configure the wireless options
Typically the gateway is setup with DHCP enabled and its LAN IP address set to 192.168.1.1 it maybe different so check the documentation. Log in to the gateway to change its options by opening up your browser and typing (192.168.1.1 for example) or the default IP address recommended in the documentation.
Your gateway may have a wizard which can discover some settings for you. Using the wizard may be easier.
These setting are necessary to set up the gateway:
Set up your gateway to be the DHCP server:
Typical settings are:
IP address 192.168.1.1
Subnet mask 255.255.255.0
Set a range of IP addresses for your network so that each computer device will have its own IP address (example 192.168.1.2 thru 192.168.1.30).
Your ISP (internet service provider) may have specific settings and software for you to use or you can have your gateway get settings automatically from the ISP; WAN IP address, DNS server addresses.
Set your gateways wireless connectivity to broadcast SSID (you can turn this off later if you wish)
You can name your SSID whatever you like (example BOBS-WIRELESS-INTERNET).
Optional WI-FI Security Measures
You can choose to setup a wireless connection with WPA or WEP security, a password will need to be entered by every computer or device that attempts to connect. Choose a password and remember it. Be sure all devices can access with the type of security you have used.
Set MAC access control; get the MAC address for each wireless card or device that accesses your gateway connection and input these addresses into the access list. Only devices that have these MAC addresses will be allowed to connect to your wireless network (sample address 00:A0:E0:F5:5E:10).
Some Gateways have firewalls that can help secure your internet connection, you should use either the gateway firewall or the windows firewall or a third party firewall software that you’ve installed. Using firewalls on top of firewalls can cause trouble that is harder to trace. So try turning on both the gateway firewall and the windows firewall and observe if you can access the internet without any trouble.
ICS - Internet Connection Sharing Instead Of A Gateway
If you are not using a gateway device and are instead sharing one computers internet connection with the other computers in your network. Follow these additional instructions instead:
In vista:
On the computer that has the internet connection that you want to share:
Click start
Right click network
In Vista you see the Network and Sharing Menu first - under Tasks click Manage Network Connections
You should find your wireless card listed here, highlight it,
Right click
Click properties (you may need to enter an administrators password in Vista)
Click sharing Tab
Check the Allow other Users to Connect… box

In XP/2000
On the computer that has the connection to be shared:
Click Start
Click Control Panel
Click Network Setup Wizard
The wizard will guide you through the process.
To Connect To A Wireless Network
In Vista
Click All programs
Click Connect To
Show all connections
or right click the network connection icon on the task bar
Click View Available Connections.
At this point you may see several available wireless networks that are broadcasting in your area. Pick the one that you want to connect to.
If this connection is security enabled then you will need a key (a password).
Troublehooting Wireless Network Connectivity
When you are using (ICS) internet connection sharing, the computer that has a connection you are sharing will be given a static LAN IP address (for instance 198.162.1.1) and the other computers should be set to obtain their IP address automatically from the host computer which acts as the DHCP server. If you run into snags be sure to be sure of the following:
Wireless cards have been installed properly.
TCP/IP protocol has been installed and enabled for use with the wireless cards.
Powering devices off and back on may be needed.
Disable firewalls until a connection becomes successful.
Once you are up and running review my safe internet surfing practices. Happy Computing!
