Ok heres the deal I just bought a xbox 360 slim a few months ago. Ever since I bought it I have been having connection issues. It connects to Xbox Live during start up, but when I go to play a game online it wont allow me nor will it allow me to do a update from xbox live. The updates will start for a second and then stop and a error message will pop up saying it cannot connect and to do a test. Sometimes before during online play it would say that the NAT was restrictive and woulndnt allow me to play. I have an older XBOX 360 (non slim) that I use a wireless connection for also and it works just fine. I dont understand why the new slim is having a problem.
