Router type: Linkys WRT110
The XBOX detects 3 NAT types. Open(you connect quickly to others and can join/host games) - Moderate(its about 50/50 on who you can play with - and Closed=Im guessing means you cannot connect to anyone.
How does NAT affect online gaming?
When you have a NAT warning, you might experience the following symptoms:
* You cannot hear a certain a player within a game or someone cannot hear you.
* You cannot join a party or your friend cannot join your party.
Some things to be aware of:
* NAT problems do not affect game play speed. A NAT warning affects the ability to connect and communicate with other players.
* You should not experience a NAT warning if you are using a wired modem connection.
* If you are using the network at your workplace or college, there is a good chance that you are behind a proxy server or firewall, which is why you are experiencing NAT issues. Contact your network administrator for help.
* If you’re using hardware that is compatible with Windows Vista or Windows 7, NAT issues should not occur.
As far as I can tell, and I am a little tech savvy- is that somewhere through the wireless router you must have to open ports that the XBOX360 communicates through. I have accessed my router and changed all of these to match the IP address I gave my 360 it was whatever my router was plus .200 I read a website that said- since I disconnect and reconnect it so often to assign a static IP address to the xbox and since other CPU's(roomies) connect and disc from the wifi and they are not static- to assign it out of range of the numbers to avoid the wifi of assigning the same ip to a laptop and disconnecting me .

I opened the ports for my 360 .200 and restarted everything, but nothing happened.
