Xbox live dont work please help

(this is a solution that i gave someone who had a wireless router... you will also need to forward the same ports even if you have a wired router...)

Ok... I have the best solution to this problem... Obviously you have wireless internet... so that means you have a wireless router... you need to login to the wireless router settings... usually it is192.168.1.1 that you type into your browser by default... if it is not192.168.1.1 in order to find your router address you need to click on start.... run... type in cmd... then in the command prompt type in ipconfig/all... your router address will be the number next to default gateway... put that into your browser and login to the router... dont exit the command box just minimize it because you will need it later...if you have not changed the password its usually either password...admin.... or nothing at all.... once you are logged into your router you need to forward the open the ports for your xbox 360 for it to be able to connect to xbox live with an open NAT... (meaning you can connect to everyone without problems) once you get to port range forwarding you are going to have to put in 6 ports for best performance... name them all XBL or XboxLive... and forward these ports... 87-89 UDP.... 3073-3075 UDP..... 80-80 TCP... 88-88 UDP...3074-3074 BOTH... and 53-53 BOTH... make sure they are enabled... find out what your start ip address is... i changed mine to 192.168.1.200with a maximum number of users at 50... (this will come in handy and i will tell you why later...) turn on your xbox 360 and go to network settings and manually change your settings... so if you have your ip address range from 192.168.1.200 - 192.168.1.249 like me... change the ip address of your xbox 360 to 192.168.1.240 (the computers that connect to your wireless router always take the low ip addresses... so setting your xbox 360 ip address to 192.168.1.240 will make it so there arent any ip address conflicts...) remember the box i told you to minimize? you are going to have to input the numbers in the command box into the boxes in the xbox.... 255.255.255.0 for the subnet mask...default gateway for the gateway... enter in th e dns settings... first one is primary... second one is secondary... save and you are done with that... if you have your ethernet cord hooked up from your computer to your xbox 360 click on start... control panel... network connections...click and highlight the network bridge and your wireless connection...once you have them both highlighted... right click... and click on bridge connections... and everything should work fine...

The reason for this part to fail differs along with the difference of the type of connection you are using to connect your Xbox 360 console as follows:

a. Direct connection to modem:

1. Make sure first no other devices connected to the modem at the same time as some modems has an Ethernet port along with a USB port so, you might think you can use both at the same time & connect the PC through USB with the console through Ethernet & that's incorrect so, we need to disconnect the PC first.
2. Turn the modem off then turn it back on after couple of seconds (by turning the modem off I mean to unplug it from the wall outlet even if you have a power button for it), then 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. If it's still not working we need to get the Physical Address of your PC to put it on the dashboard of your Xbox 360 console as some cable companies are preventing any unknown MAC Addresses from connecting, to get the Physical Address of you PC connect the PC only to the modem then follow these steps here, the physical address will look like this 00-E0-98-C1-88-C2.
4. Go on the dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Edit Settings” then “Additional Settings” tab then select “Advanced settings” & put the Physical Address of your PC without the dashes on the “Alternate MAC Address” part and select "Done", when it asks you to Apply Settings choose “Test Xbox Live”.

b. Wired connection to router:

1. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore To Factory Defaults", 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, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
c. 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", when it ask you to apply settings select "Test Xbox Live"
2. 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".
3. Just a kind of higher security that some router may use than the WEP & WPA key, you have also to accept the Xbox 360 connection to your wireless network on the router settings, you have to access to your router settings as mentioned before to check on the wireless security part whether your router apply a MAC filtering option, which is an option that blocks any unknown MAC address (the ID of any device) from accessing to your wireless network, and if it applies that kind of security you’ll find your Xbox 360 MAC address on the list there so, allow the Xbox 360 to get connected to the network, or even you can just turn off the MAC access control option instead of that, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
4. If it's still not working, you can put the Xbox 360 console - as a trial - in a closer position to the router to see wither it's going to pick up an IP address or not.
5. If even after you turn off the MAC filtering option on your router settings your Xbox 360 can't still get connected to Xbox Live you need then to update your router firmware (The router software) and if you don't know how to do so then call your ISP (Internet Service Provider) to assist you with that, then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
d. ICS (Internet Connection Sharing):
1. Go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then “Restore to Factory Default" when it asks you to Apply Settings choose “Test Xbox Live”.
2. Allow the ICS option on the PC as mentioned before, then test Xbox Live.
3. If it's still not working, set the IP Settings manually to be:
IP Address: 192.168.0.2
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.1
Then go on the Dashboard of your Xbox 360 console to “System” area then “Network Settings” then "Test Xbox Live Connection".
4. If it's still not working, you can get the IP address of your connection from the PC as mentioned before then set your IP manually on the Dashboard of your Xbox 360 console using this IP address, when it asks you to Apply Settings choose “Test Xbox Live”.
