My vista laptop connects to my network just fine. My desktop and my 360 were not connecting and having the same problem. They would "connect" but not get the right IP address. I remembered something and changed the Key Index of the WEP security on my desktop to "2" and restarted and it worked just fine. I'm pretty sure I need to change the key index on the 360 to 2 as well, but I can't find out how to do it. Is it even possible? If so, how? If not, why doesn't microsoft let me do this?
