XBOX 360 Elite problem

Depending on which type of chat session you are connected to... everyone needs to be in the same chat menu. Sometimes when switching from game chat to party chat you might still be stuck in game chat while others are in private chat or visa versa.

To talk to only players in your game: Press the Guide button, then select Party, Party Options, Chat Channel, and Game Chat.

To talk to only members of the party: Press the Guide button, then select Party, Party Options, Chat Channel, and Party Chat.

To mute an individual: Press the Guide button, then select Party, the player's gamertag, and Mute.

It is a possibility that you are not in the same chat session with your friends. they might be in a party chat with others while you are in game chat. (note you can only have a max of 8 people in one party chat) Or you might still be in a party chat (that everyone else has left) and they are in game chat.

Check to make sure that your talkback cable is plugged in tightly. Try unplugging it and then plugging it back in. If you're still having trouble, just contact them at [email protected] and they'll take care of you!

It is a compulsary update for your Xbox 360 system so it can support the feature you are trying to do. So you really might want to join to Xbox Live by creating an Xbox Live account and by signing in to Xbox Live, it will automatically install the latest firmware to update your system.

That happened to me once. You should check the wireless device or your ethernet cable( whichever one your using ). If your ethernet cable isnt plugged in on the way it will only let you log into xbox live and that may be it. Lastly try resetting your router and make sure all the wires are plugged in good.
Also Check your NAT settings. If your trying to connect to a friend, You or your friend most probably do not both have an OPEN connection. To find out if you do or dont, go to your xbox's network settings and run a test, if it comes up with a "More Information" button click it, and it will tell you what type of NAT, your xbox is set too. However if it does not come with a More Info button, then your xbox is OPEN.
Make sure both you and your friend do these tests.
If one of you is not OPEN, then you will need to either open some ports up or turn on DHCP and UPnP. But I wont go into detail until you've done the test.
Hope this helps.

your nat type is strict you can change this by opening up your internet explorer go to tools then internet options and make the needed changes

tell your friend to set his party to anyone and not just friends or invite only. its in a settings tab within his party options

there might be a reset switch on the back of the router sometimes near the power supply port if so then press that and the user name and password will be reset to default and the default settings should be either in the manual or on the bottom of you router

What is their internet connection speed?

Your friend may not have port forwarding on their home network and the network router filters the Internet NAT redirection...

Setting up a DMZ (Demilitarized Zone) on the router for the Xbox gives it unrestricted access to the internet; also puts your Xbox outside you routers firewall.

DMZ ports have to be programmed manually and the IP address also must be manually entered; The DHCP Automatic IP address puts the Xbox back behind the firewall; just duplicate the automatic DNS Server settings and the Netmask. Then choose a IP address outside the Automatic IP range (e.g. 192.168.1.175)

If that does resolve the issue see if the other Xbox needs a Live Update.

What is the model name?
