Set Up a New Wireless Home Network  

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.  
Standard   Connection speed  Radio frequency band 
802.11a  Up to 54 Mbps  5 GHz 
802.11b  Up to 11 Mbps  2.4 GHz 
802.11g  Up to 54 Mbps  2.4 GHz 
Note 
Connection speeds are quoted only in reference to IEEE standards. The speeds quoted are the 
maximum attainable under ideal environmental conditions and at close distances. In addition, the 

standards specify usable payload data rates that are less than half of the connection speed. Your 
usable connection speed will be significantly lower than the IEEE standards quote.  
When selecting your wireless network, keep a few 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.  
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 an Xbox 360 compatible access point or router (802.11 A+G recommended). For more 
information about approved Xbox compatible access points or routers, go to 
www.xbox.com/connect.  
• Some Xbox 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® XP Media Center or Windows Media Connect with your console for 
activities like watching TV. For more information, go to www.xbox.com/pcsetup. 
• 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 is 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: 
• Locate your router or access point toward 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-2, 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. Further, WPA and WPA-2 automatically change keys on a 
frequent basis, making your system more secure. 
Connect to Your New Wireless Network or an Existing Wireless Network 
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. Use the spaces provided under "Your Network 
Settings" to write down these settings before you begin.  
Note 

You can access most of your wireless network settings on the set-up screens for your wireless 
access point. Check your device's documentation for instructions about how to reach the device's 
set-up screen. If your network was set up by someone else, you will need to 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 an access point or 
router). 
2. Attach the wireless networking adapter to the back of your console (see "Attach the 
Adapter to Your Console"). 
3. Go to the System area 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. 
Your Network Settings 
Use this section to record your network settings. All computers and devices accessing the network 
with a wireless connection need to use the same wireless network settings.

Connect Your Console to Another Console 
Console-to-console system link wireless networks are also known as ad-hoc networks. In ad-hoc 
networks, a wireless adapter on one device connects directly to a wireless adapter on another 
device. An Internet connection isn't shared with this type of network, and the console-to-console 
system link connection is typically temporary. 

For console-to-console system link play, you need: 
• Two Xbox 360 consoles. 
• Two Xbox 360 Wireless Networking Adapters. 
• An Xbox 360 game that supports system link play. 
To wirelessly connect your console to another console: 
1. Attach a wireless networking adapter to the back of each console (see "Attach the Adapter 
to Your Console"). 
2. On each console, go to the System area to enter your network settings. (They will be the 
same for each console.) 
3. If all settings are correct, exit the System area. The consoles should now be wirelessly 
connected to each other. 
Troubleshooting 
If you encounter problems, try the possible solutions provided below. 
For help with a game that supports console-to-console system link play, see the game’s Web site or 
documentation. For help signing up or connecting to Xbox Live®, go to www.xbox.com/live. 
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. 
Make sure that your router is broadcasting a wireless network name (SSID). The wireless router’s 
broadcast of the SSID might be disabled. See your router documentation for information about 
enabling SSID broadcast. 
Console Doesn't Recognize Wireless Networking Adapter 
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. 
Signal Is Intermittent 
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 cause interference 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, where less interference and improved throughput is available.  
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.  
TV Pauses When Used with Console and Windows XP Media Center 
When connecting a Windows XP Media Center PC to an 802.11 A+G access point or router, use 
802.11a for the Windows XP Media Center PC and 802.11g for your other wireless devices, such as 
laptop computers.  
Unable to Save Network Settings or Password 
Restore the factory defaults on the wireless networking adapter. When you go to the System area 
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.  
Note 
Restoring factory defaults on the adapter will override your current adapter settings. 
Wireless Security Settings Rejected 
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).  
Status Light Indications 
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.
