Problems connecting to XBox live

check for firewalls on both the rtrs and the modem and try to restore xbox to factory defaults on Xbox and check .

Okay, to connect to Xbox Live using Wireless Internet you will need this:

One Xbox Wireless connection unit, There are two types, the black and white versions. The black one is able to pick up the most diverse signals and has a higher potential for speed so I recommend that one.
You will also need, of course, a high speed internet source (modem) and a wireless router connected to the modem. When looking for wireless routers look for ones with marks claiming to be compatible with Xbox Live or a Windows OS. Those have been tested to work with Xbox.

Before trying to set up your Xbox Live, make sure your Router is set up with your computer, and set to be used as a wireless router. That's another tip all together but just follow your installation CD.

Okay so here we go!

First, Connect the wireless networking adapter to the back of your Xbox.
If you have a network cable plugged into your xbox, unplug it. Check to make sure the adapter's light is on.


Here's what the light's mean:
On the gray adapter:
No light: It's not getting enough power( try plugging it another USB slot)
Green light: It is connected to a wireless router, gateway or wireless access point.
Red light: It is not connected, and is ready for configuration.
Flashing red: There is a malfunction. (try again, if the problem persists return it for a replacement)

On the black adapter:
No light: It's not getting enough power( try plugging it another USB slot)
Green light: It is connected to a wireless router, gateway or wireless access point.
Flashing green: The adapter is attempting to connect to a wireless router, gateway, or access point.
Red light: It is not connected, and is ready for configuration.
Flashing red: There is a malfunction. (try again, if the problem persists return it for a replacement)

Now the CONFIGURATION, the reason most of you are reading this:

Turn your Xbox on and go to "My Xbox"
Go to "System Settings"
Go to "Network Settings"
Go to "Configure Network"
On the basic settings tab select "Wireless mode"
Select "Scan for Networks"
Select your Wireless source.

NOTE: If your Network isn't listed you will have to manually enter it.
To do this select "Specify unlisted network"
You will need to enter your SSID
Then choose which security you used to set it up on your Computer (ie: WPA, WEP...) Then enter your security code. If there is no code then select "no security"

Your adapter should have a green light now.

Now go back to "Network Settings" and select "Test Xbox Live Connection"

If it works your good to go!

Hope this tip helps :) Tell your friends and ratings are nice. Just kidding, I just hope I helped.

It might be due to bad data cable connecting both XBOX and Modem try to Change it

USB to PC is fine, make sure you have the original installation disk for it. Then you can connect the Xbox via network cable. There shouldn't be any problem as your modem can take 2 connections by the sound of it.

go here, www.portforward.com you can find how to setup your xbox here.

If were talking a common router you will have to have a broadband connection going to the box from a local provider and a good signal along with a ethernet cable that you will need to plug into the back of the router and connect to the XBOX 360 ( Note: XBOX ) does not have access to XBOX360 Live . Microsoft offers alot of Tech support on www.xbox.com

in your case id try hooking up a wireless modem

I would greatly suggest to call Xbox live Techsupport. They will help you regarding connectivity issue and its for free!!!

xbox live connection test MTU failed

we had the same issue. Here is how we fixed it. I had the xbox 360 plugged directly into the westell 6100 modem via ethernet cable. the mtu test failed everytime. I was extremely frustrated and called microsoft and verizon (dsl) about 10 times each and they kept giving me the wrong solution. (get a new modem, get a new server, pay us money and we'll figure it out etc...) Here is what a man at microsoft told me to do and finally it worked. Power cycle your equipment (unplug modem and xbox 360 for 30 sec.) then, plug in modem first and wait until all lights are back on. Then plug in xbox and run test. In my case mtu failed again. I was then instructed to go to my dashboard and restore xbox to factory default which I did and rerun the test. This time everything FINALLY passed. We were in business. I then decided to try connecting through my airport extreme router. I power cycled again starting with the airport then the modem then the xbox and ran the test and unbelievable as it sounds it all passed and my son is now sitting happily on the couch playing a game online with his xbox 360. This took away days of my life to get this simple thing done. I was given codes to change and change back on the computer, phone calls to everyone and the solution was so simple when you finally reach a knowledgeable person. Hope this will help save someone else the time I spent!
