Hey, I downloaded Halo pc demo on my computer and when I tried join a game online it would start, and after about 15 seconds it will freeze, then disconect saying Unable to connect to server or something like that. I tried going to the Microsoft support site but that stuff didn't help. I have Comcast cable internet and run it through a wireless router and usb wireless ethernet adapter, 802.11b . If I close the game right after the message, it shows wireless connection unavalabile, then connects imediatelly back to exccelent signal. Please help if anyone of you smart computer dudes know what to do cause I am not into networking that much. Thanks a lot guys.
