Xbox Network Connection using Hub

This is the most common network configuration and is also the easiest to setup.
Step #1: Plug your network cable(RJ-45 cable) that comes from your cable/DSL modem into the uplink port of your hub. (Make sure that your uplink is switched to "on").
Step #2: Take an RJ-45 cable and run it from one of the ports of the hub, directly to the Network Interface Card (NIC) installed in your computer.
Step #3: Take another RJ-45 cable and run it from a different port of your hub directly to your xbox.
**NOTE** A switch may be used in place of a hub with the same basic setup.**

That's it! No other network changes should be needed for this configuration. Your Xbox is now on the same network as your PC.

Xbox Network Connection using Router

This is another common network configuration.
Step #1: Plug your network cable(RJ-45 cable) that comes from your modem into the WAN port of your router.
Step #2: Take an RJ-45 cable and run it from one of the ports of the router, directly to the Network Interface Card (NIC) installed in your computer.
Step #3: Take another RJ-45 cable and run it from a different port of your router directly to your xbox.

**NOTE** In steps #2 and #3, you should not use a port that is directly beside the "uplink" port on your router, if your uplink port is being used to connect to another routing device.** If your router has a built in firewall, you will need to forward ports 8602 both incoming and outgoing to the internal ip address of your pc. Consult your device manaul for port forwarding.

That's it! Your Xbox is now on the same network as your PC

Xbox Network Connection using Crossover Cable

This is the last network configuration. For this setup you need at least one NIC card.
Step #1: Plug your USB cable that comes from your modem into your PC's USB port. This should already be done, if you have a usb modem for your current internet connection.
Step #2: Take an RJ-45 cable and run it from an installed NIC card on your PC, directly to the Xbox.

**NOTE** A crossover cable is only needed if you are connecting the Xbox directly to the second NIC card. If you have a device such as a switch, hub or router in between you should use a standard RJ-45 cable. This type of network setup also requires "Winroute©", a program downloadable from the world wide web. Consult the manual for specific instructions on how to set this up. Also if you have a USB ethernet adapter, you may use any of the setups described herein. USB ethernet adapter basically converts a USB cable into an RJ-45 cable.

That's it! Your Xbox is now on the same network as your PC.

look out for the driver of the wireless card. check the system configuration were you have all installed hardwares and see if you can find thr card there. if it is not there, then you may have to get the driver cd and re install it. other wise uninstall the driver and re install it again. but first, go to network connections and see if it is there or if it has been disabled. if it is disabled, enable it and you will be fine

You can use a wireless network to share Internet access, files, printers, and more. Or you can use it to surf the Web while you're sitting on your couch or in your yard. Plus, it's easier to install than you think.
There are 4 steps to creating a wireless network:
1.
Choose your wireless equipment
2.
Connect your wireless router
3.
Configure your wireless router
4.
Connect your computers
For Windows XP users, Windows XP Service Pack 2 is not required for wireless networking, but it does make things much easier. Service Pack 2 also helps protect you against hackers, worms, and other Internet intruders.

Connect your computers
If your computer does not have wireless network support built in, plug your network adapter into your USB port, and place the antenna on top of your computer (in the case of a desktop computer), or insert the network adapter into an empty PC card slot (in the case of a laptop). Windows XP will automatically detect the new adapter, and may prompt you to insert the CD that came with your adapter. The on-screen instructions will guide you through the configuration process.
Note: The steps below only apply if you're using Windows XP Service Pack 2. If you're running Windows XP and you don't have Service Pack 2 yet, plug your computer into your wireless router and download and install Windows XP Service Pack 2.
Windows XP should show an icon with a notification that says it has found a wireless network.
Follow these steps to connect your computer to your wireless network:
1.
Right-click the wireless network icon in the lower-right corner of your screen, and then click View Available Wireless Networks. If you run into any problems, consult the documentation that came with your network adapter. Don't be afraid to call their tech support.
2.
The Wireless Network Connection window should appear and you should see your wireless network listed with the network name you chose. If you don't see your network, click Refresh network list in the upper-left corner. Click your network, and then click Connect in the lower-right corner.
3.
Windows XP prompts you to enter a key. Type the encryption key that you wrote down earlier in both the Network key and Confirm network key boxes, and then click Connect.
4.
Windows XP will show its progress as it connects to your network. After you're connected, you can now close the Wireless Network Connection window. You're done.
Note: If the Wireless Network Connection window continues to show Acquiring Network Address, you may have mistyped the encryption key.
