DNS Failed on Xbox 360 Live Test

And the reason for this part to fail differs along with the difference of the type of connection you are using as follows:

a. Direct connection to modem:

1. Using a modem you can't connect more than one device so make sure that the only device connected to the modem is the Xbox 360 console.
2. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore To Factory Defaults" and when it ask you to apply settings select "test Xbox Live"

3. Turn the modem off then turn it back on after couple of seconds, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
4. If it still not working, try to get the DNS addresses (primary & secondary) from your PC as mentioned before and set them manually on the dashboard of your Xbox 360 console, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".

b. Wired or Wireless connection to router:

1. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore To Factory Defaults" and when it ask you to apply settings select "test Xbox Live"
2. Turn the router off then turn it back on after couple of seconds, by that I mean to unplug it from the wall socket then reconnect it back.
3. If you are using a Wireless connection go on the Dashboard of your Xbox 360 console to the "system" area then "Network Settings" then "Edit Settings" then select your wireless settings part down there "Wireless Mode, Network Name,..." the console will automatically then search for your wireless network and when it find it and you select it, it will ask you to enter your wireless key which is called WEP or WPA key - you can find it written on your wireless router or then you need to contact your ISP (Internet Service Provider) to get it from them - when it ask you to apply settings select "Test Xbox Live".
If it's a Wired connection Just try once more to "Test Xbox Live Connection"4. If it's still not working, set the DNS (primary & secondary) with the same number of the Gateway on the IP settings, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Edit Settings" you'll find the gatway on the IP settings put it the same on the Primary & secondary DNS.
5. If it's not working still, then you have to go to your PC and get the DNS Server Address from there as mentioned before, and set it manually on the Dashboard.
6. If it's still not working, you have to contact your ISP or router manufacturer to open or forward the 3 Xbox live ports which are:

• UDP 88
• UDP 3074
• TCP 3074

Or you can check it on www.portforward.com, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".

c. ICS:

1. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore To Factory Defaults".
2. Allow the ICS option on the PC as mentioned before and make sure the the "Local Area Connection" then is showing connected.
3. If it's still not working, turn any firewall on your PC off.
4. If it's still not working, try to get the DNS addresses (primary and secondary) from your PC as mentioned before and set them manually on the dashboard of your Xbox 360 console, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
5. If it's still not working, you have to contact your ISP or router manufacturer to open or forward the 3 Xbox live ports which are:
