My xbox will not connect to wireless network, i have tried using both wep and wpa passcodes, unplugged and replugged both the wireless router and the wireless adaptor on the xbox, i have fiddled with firewall settings and the light on the adaptor is on to show it is working. plz help.

Connect the appropriate wireless network adapter to the console. On the Xbox, a Wi-Fi adapter that connects to the Ethernet port (sometimes also called a wireless network bridge) must be used. Alternatively, the Xbox 360 is also designed to work with certain Wi-Fi game adapters that connect to a USB port.

Turn on the console and navigate to the wireless settings screen. On the Xbox, the menu path is "Settings -> Network Settings -> Advanced -> Wireless -> Settings" On the Xbox 360, the menu path is "System -> Network Settings -> Edit Settings."

Set the SSID (network name) on the Xbox to match that of the wireless router. If your wireless router has enabled SSID broadcast, the SSID name should appear pre-selected on the Xbox display. Otherwise, select the "Specify Unlisted Network" option and enter the SSID there.

Specify "Infrastructure" as the Network Mode. (Infrastructure is the mode used by wireless routers.)

Set the Security Type to match that of the wireless router. If your router uses WPA encryption and the type of adapter connected to the Xbox does not support WPA, you will need to change your router settings to use WEP encryption instead.

Note that the standard Microsoft Xbox 360 Wireless Network Adapter supports WPA while the standard Microsoft Xbox Wireless Adapter (MN-740) only supports WEP.
Save your settings and verify the network is functional.

On the Xbox, the Wireless Status screen displays whether a connection has successfully been made with the wireless router, and the Connect Status screen displays whether a connection has successfully been made through the Internet to Xbox Live.

Reset Belkin WEP key or WPA pass phrase

SSID, WPA and WEP are things used to identify and access an wireless network/router.

SSID is the name of the wireless network you want to connect to.
WPA and WEP are forms of encryption/security for the wireless network. Basically it's the password to get onto the wireless network.

Most routers broadcast the SSID information, so you should be able to select it from a list on your Xbox (Scan for Networks option). If not you can also manually enter it.

The WPA/WEP you'll have to know and enter manually. If you forgot it, you can find it in your router's settings. Here's a guide to finding/accessing the password; all you need is access to a computer that is already on the wireless network.

And just in case, here's an official guide from Microsoft for troubleshooting wireless network problems.

Hope you get it sorted out!
(Personal opinion: Wireless is a pain; just use an wired ethernet connection)
