   Important

   Do not use the Xbox 360 Wireless Networking Adapter or its antenna to lift the console. It could break and the console could fall.

Home wireless networks are also called infrastructure networks. In an infrastructure network, a wireless access point, wireless gateway, or wireless router distributes your Internet connection to your wireless home computer and devices. With a wireless networking adapter, your console becomes one of the wireless devices on your home network.

If you don't have an existing home wireless network yet, you'll want to make a few decisions before you get started. Specifically, you'll need to decide on the wireless standard you'll use, the network hardware you'll need, and your network security.

Wireless Network Basics

Your wireless networking adapter communicates by radio transmission. Radio waves travel in all directions, and can be transmitted through walls and floors. The radio signal weakens rapidly as it travels through structures, especially masonry, such as stone and brick. Metal objects, such as refrigerators and mirrors, reflect radio signals, preventing straight path communication. The layout of your home can be a factor in what wireless network standard you choose.

Choose a Wireless Network Standard

The Xbox 360 Wireless Networking Adapter conforms to all three current wireless network standards (802.11a, 802.11b, and 802.11g), and so works with networking devices that support any of these standards. (802.11 is a series of radio communication standards developed by the Institute of Electrical and Electronics Engineers (IEEE) for wireless local area networks.)

The main features that distinguish these standards are connection speed and radio frequency.

When selecting your wireless network standard, keep the following guidelines in mind:

1. The 802.11a standard offers the same speed as 802.11g. A 5-GHz band (802.11a) is also less susceptible to interference from common devices, such as 2.4-GHz cordless telephones, cell phones, and microwave ovens. Further, in areas where neighboring wireless networks can be detected, interference can be a problem. Because of the limited number of channels and the popularity of 2.4-GHz networks, a 5-GHz network is likely to experience less interference from a neighboring wireless network than a 2.4-GHz network and provide a better overall wireless connection. Although a 5-GHz network offers many channels, 802.11a networks are not widely supported by other devices that you may also want to add to your network, such as laptop computers.
2. An 802.11g wireless network is compatible with both 802.11g and 802.11b devices. However, any 802.11b devices operating on your 802.11g network will slow it down. If you have a dual-band router (with both 802.11a and 802.11g bands), try using your Xbox 360 console and wireless network adapter on the 802.11a band and your other devices on the 802.11g and 802.11b bands. The Xbox 360 console in this configuration will have the maximum bandwidth while remaining networked with other devices on 802.11g or 802.11b.
3. If you use wireless controllers, you may get better performance using 802.11a (5-GHz band) for your network connection, since the wireless controllers operate on the 2.4-GHz band.

Choose Your Network Hardware

Consider the following guidelines when purchasing network hardware:

• Use a compatible access point or router (802.11 a+g recommended).
  
  For a list of Xbox Live Compatible hardware for Xbox 360, see Compatible Home Networking Equipment.
• Some compatible routers are dual-band a+g (dual-band 2.4-GHz/5-GHz, 802.11a + 802.11g/b). Using a dual-band router lets you configure your console to achieve maximum bandwidth and the best possible connection. This is particularly important if you are using Microsoft Windows Media Center or Windows Media Connect with your console for activities like watching TV.
  
  
• When using a dual a+g access point or router, make sure the 802.11a and 802.11g networks have unique network names (SSIDs).

Make Your Wireless Network Secure

Because wireless networks use radio signals, it's possible for other wireless network devices outside your immediate area to pick up the signals and either connect to your network or capture the network traffic. To help prevent unauthorized connections and reduce the possibility of eavesdroppers listening in on your network traffic:

• Position your router or access point as close as possible to the center of your home. This decreases the strength of the signal outside your home.
• Enable wireless security on your router or access point. Your wireless networking adapter supports WPA and WEP security. When you enable wireless security, you establish a key that "encrypts" the data being wirelessly transmitted so that it is decipherable only by computers with the same key. Furthermore, WPA automatically changes keys on a frequent basis, making your system more secure.

  Note

  Some copies of the instruction manual for the Xbox 360 Wireless Networking Adapter state that the adapter is compatible with the WPA2 security standard. At this time the adapter works only with WPA and WEP security.

Connecting your Xbox 360 console to a new or existing wireless network is easy as long as you know what your wireless network settings are. It's a good idea to write down these settings before you begin. (All computers and devices accessing the network with a wireless connection need to use the same wireless network settings.)

You can access most of your wireless network settings on the set-up screens for your router or wireless access point. Check your device documentation for instructions about how to reach the device set-up screen. If your network was set up by someone else, contact the installer for a user name and password to access the set-up screens of your wireless access point.

To connect your console to a wireless network:

1. Turn on your console and any wireless networking devices (such as a router or an access point).
2. Attach the wireless networking adapter to the back of your console as described above.
3. Go to the System area of the Xbox Dashboard to enter your network settings.
4. If all settings are correct, exit the System area. Your console should now be connected to your wireless network.

Make sure the power light on the adapter is on. If it isn't, check the USB connection. Try disconnecting the adapter cable and connecting it again.

Console Doesn't Detect Wireless Network

You might be out of range of your wireless network. Place your Xbox 360 console in the same room as your wireless router or second Xbox 360 console and try again. You can also try the following suggestions:

• Verify that an Ethernet cable is NOT plugged into your console's Ethernet port.
• Verify that your network's wireless access point, gateway, or router is powered on.
• Make sure that your router is broadcasting a wireless network name (SSID). The wireless router broadcast of the SSID might be disabled. See your router documentation for information about enabling SSID broadcast.
• Remove any obstructions between your Xbox 360 console and your wireless access point.
• Turn off any devices that may interfere with your wireless network (for example, microwave ovens or 2.4-GHz telephones).
• If you are using an infrastructure network, make sure the security settings on your wireless adapter match those on your wireless access point, gateway, or router (for example, your WEP key or WPA passphrase must match).
• If you are establishing an ad-hoc network, make sure the network name, channel, band, and security settings match the settings on the device with which you are establishing a connection.

Some wireless devices using the 2.4-GHz radio frequency band—including the wireless adapter (MN-740) designed for the original Xbox console, most 2.4-GHz phones, some cell phones, and microwave ovens—may interfere with your wireless networking adapter.

If you experience network performance issues, try moving your 2.4-GHz device(s) away from your console (or vice versa). Or, upgrade your wireless network for 802.11a/g operation and set your adapter to operate on 802.11a, which should reduce interference and improve throughput.

Before relocating your console or wireless access point:

• Imagine a straight line between your Xbox 360 console and the access point.
• Locate your console and access point or router so that as few obstructions as possible exist along the straight line.
• Allow no more than two walls or two floors between the wireless adapter and the central access point.

When connecting a PC running Windows Media Center to an 802.11 a+g access point or router, use 802.11a for the PC and 802.11g for your other wireless devices, such as laptop computers.

Restore the factory defaults on the wireless networking adapter. When you go to the System area of the Xbox Dashboard to restore the factory defaults, the adapter status light will blink green and red, and then turn solid red to indicate that the defaults have been restored.

When entering your wireless security settings, remember that WEP keys must be in hexadecimal (0–9, A–F) format and WPA passphrases may be alphanumeric (consisting of both letters and numbers).

The status lights on the Xbox 360 Wireless Networking Adapter indicate the following:

• Green steady: Adapter is on and connected to a wireless access point (infrastructure) or another wireless device (ad-hoc).
  
  
• Red steady: Adapter is ready to be connected to a wireless network.
  
  
• Red blinking: Hardware failure.
